This paper will provide information about the concrete brand produced in the factory for the prefabricated elements and the comparison of the results given by the test of resistance to compression and the results of the test of the hammer impact of the sclerometer. The idea and the need to conduct this study arose for 2 main reasons: first, from the poor results often obtained from sclerometer impact to the elements in the field, despite the compression resistance test with cubic samples taken in the concrete cast and the carrot test directly on the element assembled in the building provides good results. Secondly, to have a connection between the values of the concrete brand resulting from the pressure resistance test with a press performed in the laboratory and the impact test with the sclerometer hammer which is often performed in the field under different conditions. The sclerometer impact tests will be performed on each cube sample before it is broken, in the press, and the sclerometer impact tests will be performed on the concrete elements from which the cube sample was taken on the day that this sample will be destroyed. The predicted results are relatively close values related to the age between14th day and the 28th day of the concrete maturity, as determined by the manual of the sclerometer that the study is going to use, and other values for the other days (1, 3,7,14,28). But in fact, just like in the field tests done before, it is noticed that the results obtained from the blows with the sclerometer hammer are weak. The aim of the paper is to find a logical connection between the results of these 2 types of tests. This study will contain information on the composition of the concrete produced in the IXHEM SHPK factory (ltd) located in Durres-Albania, the brands of concrete on different days for different elements, and the comparison of the results between the 2 methods mentioned above.

Acoustic pollution is one of the main pollutants nowadays but it is not considered of great importance in the construction field, despite some studies showing that most of acoustic pollution is produced by buildings under construction and roads with high traffic. The aim of the paper is to compare the noise levels at different time of the day in two different buildings which have different characteristics and different construction materials. The goal is to understand how well sound isolated civil buildings are and how engineers have calculated the noise levels based on the specific area. The buildings are located at “Zogu Zi”, Tirana, Albania. The case study area is an area that consistently harvests noise from heavy traffic. The impact of the noise and the sound insulation materials in the wellbeing of the inhabitance is going to be analyzed too. The aim of this paper is displaying a comparative study on the actual noise levels generated by this area. It indicates the acoustic properties of the current building materials followed by a more suitable soundproof insulation.

A bioclimatic eco-renovation project can be implemented in every cell of the city, both in the existing buildings and in the new ones. Reducing the demand for energy can result in the creation of zero-energy houses. Implementing a bioclimatic eco-renovation project is a courageous and innovative initiative. The heat exchange through the building envelope should be controlled since in the early stage of design. The passive design strategies depend on the orientation of the different areas of the building, considering also the glazing areas, the use of different shading devices, the thermal trap zone, thermal masses, ventilation strategies, etc. Greenhouses as one of the basis systems of passive strategies, are designed to conduct desired air to other spaces via direct opening adding special materials for conduction. Greenhouses are constructed to connect inner spaces as a heat transferor. They have the character of a transitional space, located between the indoor and outdoor environment. During the winter their inner temperature is higher as a consequence of the thermal trap meanwhile during summer such structures must be ventilated. Thermal mass is generally applied to the floor or masonry. The use of shading devices is also important during summer in order to reduce the penetration of solar radiation into the building as well as planting vegetation. The applied green houses in Tirana case study are sized according to the international normative, considering also the climate characteristics of the zone. The implementation of the solar chimneys (another passive system) is necessary in order to subtract the fresh air form the anti-bombing underground tunnels, bringing it to the customers (residents). The benefits of such strategy are enormous. The combination of them with the anti-bombing tunnels located in the selected neighborhood in Tirana is crucial, in order to subtract the cool air from the underground due to temperature and air pressure differences. The aim is to include the existing buildings within the comfort zone without the use of mechanical systems. There are also undermined temperature measurements of the underground and ground surface, very close to the zone during winter and summer, in order to better clarify the temperature differences between the areas. It is found that the temperatures of the underground area are relatively constant compared to the ground surface. Photovoltaics panels implemented in the project can convert sunlight into electricity and are considered as solar systems. According to the electricity demand of the inhabitants, specific calculations using Canadian RETScreen expert application in order to fulfill their electricity requirements for one of the buildings located in the neighborhood are undermined. It is observed that the implementation of the PV panels will reduce the GHG emission compared to the base case and also the gross annual GHG will be reduced too. The recycling of the rain water and wastewater is considered too, using reed bed strategy and fertilizing bathing tubes. The solar tube is another technology applied in all the dwellings, which turned to have a very good performance, saving a lot of electrical energy. A specific and unique proposal is designed in order to fulfill graphically the proposed ideas in combination with a software simulation application, MEEC (Montenegrin Energy Efficiency Certification) which is finally used as a tool of better understanding the thermal performance of the considered building as part of the neighborhood. Two scenarios are involved in order to draw conclusions and enhance the building thermal performance category. It is revealed that the added greenhouses involved in the second scenario contribute massively improving the thermal performance of the building.

The main bioclimatic passive strategies include optimization of the use of natural light, reducing the need for artificial light, maximizing the solar gain using thermal traps and promotion of natural ventilation in order to avoid the need for air conditioning for cooling. The usage of cool air passing through the underground tunnels located in the selected neighborhood in Tirana in order to enhance the cooling process is of huge importance. On the other hand, the building must benefit from the passive solar systems and thermal energy conservation strategies implementing thermal insulation materials. These strategies improve both the indoor comfort and economic aspect. The aim is to be aware of the community for the big benefits of such strategies, increasing the number of passive bioclimatic implementations not only in Albania but also in the region. Through the use of such systems the building can obtain indoor thermal comfort without a traditional cooling system. The passive systems discourage the use of mechanical systems for lighting, cooling, and heating, supporting the natural phenomena such as power of the sun, underground constant temperature, wind direction, and other climate parameters. The selection of the proper thermal insulation materials is complex and sometimes determinant in order to reduce heat gain. The thermal accumulation capacity depends on material width, material type, density, and porosity of the material. The top insulating materials are mostly used in the Tirana. Albania is the expanded polystyrene (EPS). The energy needed for its production is relatively low compared to the other insulating materials. Passive design encourages the application of such kind of materials, reducing the ecological footprint of the buildings. Water recycling is another aspect that bioclimatic design takes into consideration, promoting it. The use of specific materials in order to recycle the rain water through drainage is an important task. The building is faced with significant thermal losses due to the windows. The sizing of the glass area, the orientation, as well as the choice of glass determine the penetration of solar radiation in the building. The selection of the correct type of window is also a complex task. The designer should consider the climate type, the area of the openings, the typology of the window, and the characteristics of the window materials and its thermal performance before implementing it. The usage of the high thermal capacity materials (stone, water) is getting noticed nowadays in bioclimatic and passive building designs. These materials are efficient when having large surfaces and face a strong solar radiation. PCM (phase change materials) are innovative materials that undergo a physical transformation stabilizing the temperature fluctuations in the indoor area of the building archiving and improving thermal comfort parameters inside the building. The typology of such materials and their field of implementation is a very large one. Such materials have resulted to be an added value when implemented and are part of passive systems such as Trombe wall, enhancing its performance. The piezo-electric materials are another group of innovative materials used to gain energy. Their role in energy gaining nowadays is very small but the future belongs to them. The use of such materials is promoted by bioclimatic design benefiting by their mechanical properties, producing electricity. The Empathic house is one of the examples of the future generations. The implementation of some other materials such as ETFE in the building envelope in contrast to glass allows the long-wave penetration inside the building increasing the solar gain capacity. The visibility of such materials is still under examination.

The stock of Albania buildings dating between 1955 and 1985 during the communist period is a very powerful and important footprint not only in the city of Tirana, Albania, but all over the country. This category of buildings is positioned mostly in the center of the city, within the inner historical ring of the city of Tirana. They are designed considering the mottos: standardization and typification representing the standards of the time. In the city of Tirana almost in every neighborhood are located underground anti-bomb tunnels. Since the majority of them nowadays are out of functions, they are destroyed. Despite this fact, the specific neighborhood taken into consideration includes in the inner block area these shelters. The socialist regime and professionals of the time do not consider the orientation of the building toward sun in order to benefit from the solar radiation. Furthermore, the buildings are placed randomly in the urban structure of the city. Regardless to that fact the analysis of the WWR and WFR showed relatively good results compared to the international case studies. Building thermography and U-value measurements of the building showed poor results compared to international and national standards. Taking into consideration this fact, immediate improvements are needed in order to include the buildings within the comfort zone, enhancing its thermal potential category. The analysis of the existing building structures and their construction materials is crucial in order to have a better understanding of the thermal potential of them. The structures are measured and designed according to their actual physical conditions. The buildings require an immediate energetic requalification, avoiding at the maximum the thermal bridges as part of them.

Climate has a strong influence on urban planning and also plays a fundamental role in soil composition affecting the character of plants and animals. The climate is a combination of different meteorological factors that characterized a specific region over a specific time. The movement of the Sun and Earth inclination toward it is the most important factors which determine the characteristics of the climate. The global movement of the air from equator toward poles and vice versa influences also drastically the climate change. In this section are also included breezes. Also air relative humidity plays an important role shaping the climate. It plays a very important role in cloud formation. The built environment can influence the urban climate of the city through height, form, and applied building materials. Building form and shape, building materials, openings in the façade, and their orientation often are determined by climate parameters. Urban density, directions, and street network and their shape are related to the climate change, apart from topography. Density of urban structures produces important effects on the microclimatic conditions in external spaces. The bioclimatic behavior of each type of outdoor spaces depends on the relationship with its surrounding elements. The city of Tirana is included in Mediterranean climate characterized by hot dry summers and mild cold wet winters with high daily thermal excursions. All of the countries bordering the Mediterranean Sea benefit from the Mediterranean climate. Specifically spotted, Tirana is part of Mediterranean coastal zone (<22 °C in temperature) with an annual temperature of 15.3 °C. In the inner city can be found areas with high pollution, which normally contain a high percentage of business and industry, settlements, and traffic, so-called “sealed” areas. They constitute “hyperthermic areas” or “heat islands”. The term “heat island” describes built-up areas which are hotter than nearby rural areas. Heat islands can affect communities by increasing summertime peak energy demand, air-conditioning costs, air pollution, greenhouse gas emissions, heat-related illness and mortality, and water quality. The aim of the bioclimatic design is also the reduction of the heat-island phenomenon. The use of materials with different energy absorption capabilities and integration of green spaces into urban life is important. The vegetation effects on microclimate and in the built environment are present. Trees are necessary and indispensable to human life. They provide shelter for us, provide food, and their fibers cloth us. Implementation of the green belts in the city is one of the strategies in order to reduce heat-island effect. Vegetation also can provide a deep feeling of attachment to certain places and trees which are part of it. The use of trees avoids monotony and ensures diversification. They play a crucial role creating microclimates which influence the thermal comfort of people reducing heating or cooling loads. Vegetation also creates cooler microclimates around the building through evapotranspiration, reduces wind speed, regulates humidity, and reduces temperature. It is observed that tree species have a greater influence on humidity than on temperature. Trees can also absorb and reduce the reverberation time of the sound, behaving as sound buffers. The benefits of tree plantation in the inner city are enormous and they can’t be neglected.

The bioclimatic architecture is still fascinating to all of us. The lack of energy that the world is facing nowadays is forcing architects and engineers to implement smart solutions benefiting at the maximum from nature itself without considering the primary sources of energy that the world is actually using. Bioclimatic design has the roots in history, despite the fact that little attention has been paid to it throughout history. It is important to understand how natural systems operates, creating closed or semi-closed systems that mirror the ecological systems on Earth. The components of bioclimatic design deal mostly with: climate type and requirements; adaptive thermal comfort; vernacular and contextual solutions; tools and assessment methods; microclimate; sun path; wind; rain; passive and active systems and responsive forms. The aim of the bioclimatic design is to improve the natural environment through the utilization of clean energy and renewable energy system; to reduce the need for energy for heating purposes; and to reduce the energy for cooling proposes, air conditioning and lighting. Furthermore, bioclimatic design involves changes in regulation, improves the house comfort, and also improves urban quality of life. Bioclimatic buildings also include the use of building elements such as walls, windows, roofs, and floors, in order to collect, store, and distribute solar thermal energy and to prevent overheating. The aim is to manage the energy flows providing comfortable conditions during the entire year and the entire day. Minimization of thermal losses and utilization of climatic conditions (climate; microclimate, sunrise) are other important issues to consider. According to many studies, the best orientation for a building in order to maximize the heat gain during winter is east–west and the primary façade should face south. Sustainability is mostly an outcome, rather than a goal or a process. The aim of all designers is to reduce the ecological footprints and to improve the quality of life. The energy sustainability and the use of natural resources must be an integral part of a sustainable development. Nowadays, there are softwares that are developed in order to carry out environmental assessment tools and standards, in order to draw conclusions about internal thermal comfort; uncomfortable times in the building during the entire year; the need for shading devices and their dimensions; energy use, energy cost, etc. Simulations are essential in the design process. Examples chosen as case studies participate to have a better insight into the overall approach of the bioclimatic design. Applying the principles of bioclimatic design remains still a challenge in redefining the perfect bioclimatic house.

The city of Tirana during the period of socialism (1944–1990) has been through a relatively large change in the field of construction. The motto of the time was standardization and typification in order to build quick, and to meet the needs of the population, fulfilling the demands of the market for new constructions. The quality of the constructions was very poor in terms of building materials and surface area predicted per inhabitance. Meanwhile, the predicted static parameters of the buildings reveal to be in good performance. The specific area taken into consideration located in the outskirts of the inner historical ring of Tirana is characterized by constructions realized during 1965–1980. The buildings are standing using retaining walls, according to the technical construction parameters of the time. The aim of the questionnaire implementation in the neighborhood is to have better insights into the social, economic and inhabitance behavior within the neighborhood. It is going to be analyzed their lifestyle, pollution in the area, their level of satisfaction, the actual conditions of the buildings, electricity consumption, water consumption, heating and cooling instruments, ventilation habits, etc. The results showed that the level of loyalty to the buildings is high, although the building physical conditions are very poor and their level of satisfaction living in the neighborhood is above average. Their level of satisfaction considers more the location of the neighborhood than the physical conditions of the buildings. The inhabitance agreed with a hypothetic thermal performance improvement of their buildings although sometimes the additional surface is required as the main priority and as a very important quality of life parameter.

Tirana, immediately after it was declared the capital of Albania on 11 February 1920, has undergone many changes in its morphology and city context. The capital is located in the heart of the country. During its lifespan, Tirana has adopted four important regulatory plans starting from 1923. The Western ideologies of the time influenced drastically the city development. The influence of such ideologies was stopped immediately though the imposition of communist ideas, after the Second World War. Rational building forms were created which could be standardized in order to reduce construction costs. Meanwhile, in Western Europe, this current was implemented during the 1920s, as a response to social problems. The communist regime established strict anti-urbanization policy that aims to foster the development of rural areas and the suburban industrial districts in order to control urban growth and demographic mobility. All the regulatory master plans of Tirana, climate data of the city, the actual situation of the specific neighborhood, its orientation toward north, are considered in order to gather information and to implement the correct bioclimatic eco-renovation in the area. A special attention will be given to the underground tunnels which were constructed during the communist regime all over the city (1945–1983) as a response to a hypothetic nuclear attack, in order to shelter the inhabitance against bombing. These reinforced concrete tunnels will serve not only as an area for water collection and recycling strategies but also for cooling with zero energy expenditure for the inhabitants as a consequence of differences in temperature and air pressure. This strategy benefits from the underground air temperature in both seasons (winter and summer). It envisages the handover of these tunnels by the community. Nowadays, such structures are abandoned and denigrated. The realization of these structures required large amounts of money from the state budget. Considering that fact they need to be vitalized and reused, using different methodologies and strategies as part of the city. After the communist regime in the city of Tirana, two other regulatory plans were implemented which observe the city from another perspective, determining and evaluating Tirana’s real values as a city of the future, but not defining yet Tirana as an Ecocity. The ecological potential of Tirana including its outskirts is to be considered. Its flora and fauna are very rich, containing a mixt of species and plants. Regardless, the city of Tirana is suffering from different kinds of pollution such as air and noise pollution which are above EU and WHO norms. Tirana benefits from a Temperate Mediterranean climate. Furthermore, the benefits of the solar radiation are enormous. Unfortunately, nowadays, the city of Tirana is not profiting much from it. This chapter is in search of an overall view of the city of Tirana, and its great potential discovering its underground and upper ground historical secrets.

The standards of energy and environmental design are improving day by day, are flexible enough, and in continuous change. The designers are the first ones which introduce the inputs into the system in order to improve it. The overall city should be planned as a socio-natural hybrid system. The LEED program has been developed in the US since 1998. It has been adopted in almost 40 countries and it is widely used by public. The LEED standards are based on reducing overall impact rather than on a specific issue or topic, trying to be green as much as possible. The reliance to outside sources (programs and standards) is also important in order to enlarge the expertise area and the variety of subjects. The green city should be well planned and well documented since the early stage of design, reducing the costs and synchronizing the work of different systems that operates within the building. The LEED standards involve the environmental, economic, and social impact, regardless at this point the standards are socially neutral. The city planned according to LEED standards is a socio-neutral hybrid one. On the other hand, BREEAM is established since 1990 in the UK and certifies the sustainability of buildings. For each environmental certification, there exist differences between various criteria related to building energy efficiency. The evaluation of the performance improvement over specified baseline requirements is the common point of the two building standards. The sustainable assessments such as BREEAM or LEED can be applied or adopted in any region of the world. The Albanian case does not adopt any of them. Based on EPC (energy performance certificate), the building is considered to be in compliance with the minimum performance requirements of energy, aiming to achieve optimal levels of energy consumption for a typical use of the building. The building is considered as zero energy building when the ratio of the total energy consumption of the current building per sqm of the surface is equal or be less than 50% and the ratio of renewable energy produced in the building during a year compared to the consumption of total energy of the current building for one sqm of the surface. Expressed as a percentage is equal to or greater than 50%.

The aim of this paper is to analyse the people behaviour in different age buildings and different buildings typology. In the city of Kruja (Albania) exists mostly three types of buildings: the historical ones (medieval), the socialist ones (which belongs to the former communist regime) and the modern buildings. Each of them has different social and physics characteristics, different energy exchange and different building materials. The influence of all these characteristics in the exchange of energy and how they reflect in changing the lifestyle of Kruja’s people is going to be analysed. A questionnaire will be undertaken to understand the way of life of Kruja’s people and to draw conclusions. A comparative analysis between all these typology of buildings will be undertaken in order to understand better the behaviour of Kruja’s people lifestyle living in these buildings. Although the conditions are not good, people tend to get a high level of place attachment and loyalty to the building they are living. The biggest energy consumers are the historical buildings and socialist ones; although the bills of the electricity are smaller than the third category they consume alternative energies and have major problems with thermal bridges. The most unfriendly categories are the socialist buildings. They prefer not to socialize much in comparison with the other two categories.

Ecological and livable cities need an objective method to be judged. This paper is in search of a method to determine the level of livability, ecology, and energy efficiency, beginning with ecovillages, ecocities, ending with Tirana capital of Albania. Examples chosen for this methodology are: Ecovillages: 1. Auroville; India; 2. Sieben Linden, Europe; 3. Ecovillages at Ithaca, USA; 4. Ecoovila, Brazil; 5. Mbam and Faoune, Senegal. Ecocities: 1. DongTang, Shangai, China; 2. Masdar, Abu Dhabi, United Arab Emirates; 3. Arcosanti, Arizona, USA; 4. Chang Chun, China; 5. Zira island, Baku Azerbaijan; 6. Globe Town, Nizhny Novgorod, Russia. A special device is introduced for comprising analyze of this paper. Weighing and final score are evaluated in the conclusion. The livable city should be merged with the overall development, ecological progress, sustainable, passive, and bioclimatic design in order to withstand the test of time. Ecological and sustainable cities need to properly make up for the existence weakness of cities construction under fine ecological environment. The intention of this comparative study is an attempt to assess, even improve the lives of the citizens of Tirana, Albania. There are some attempts nowadays to environmentally render the city but due to the lack of a genuine ecological and renewable energy study in Tirana, the city suffers the consequences. The first settlements which consider the renewable energies are known as Ecovillages. They demonstrate their impact on the community and the energy consumption. Ecovillages have evolved into ecocities of the future, most of them not completed yet or in design phase. For both groups (ecovillages and ecocities) tables of matrixes are constructed in order to better understand their potential and functionality, and their special features and characteristics. This chapter is in search of analyzing the eco-potential and renewable energies for further development of future cities, considering ten case studies all over the world and ending with Tirana. The fossil fuel age is quickly coming to an end, so, the world must be prepared for the implementation strategies and utilization of renewable and alternative energies

Ecological and livable cities need an objective method to be examined. This book is in search of a method to determine the level of livability, ecology and energy efficiency. Ecological and sustainable cities need to properly make up for the existent weakness of the city's construction under fine ecological environment. The intention of this comparative study is an attempt to improve life quality in Tirana, Albania. It gives examples of successful strategies, eg bioclimatic solution through passive solar systems and the use of underground tunnels. This book is aimed at researches, professionals, architects and city planners.

The foundation of a building connects the main body superstructure to the ground. Every form of foundation and footing have a unique application in a given location for a certain weather condition. Understanding the foundation work is crucial for carrying out building activities. Due to the variety of structures they support, foundations are frequently built in different subsoil conditions and are exposed to static loads. The proper evaluation of soil-bearing capacity is fundamental to the construction of various buildings. One of the quick, easy, and affordable ways to determine soil carrying capacity is the plate load test. The effect of subsoil conditions on the test results is assessed and analyzed in thorough parametric investigations. An overview of axial static and dynamic plate load testing will be given in this study. This article presents detailed processes and schematics. In an effort to highlight the differences and shared characteristics of the results, computational test results of the static load plate test and the dynamic load plate test are contrasted. A load cell, a steel plate, a hydraulic actuator mounted on a big truck to apply a load, a load cell to measure the load, and one or more linear variable displacement transformers to measure the vertical displacements make up the test setup. The maximum thrust load that should be applied to a fixed or stationary actuator when it is not moving is known as a "static load depending on the actuator's static load capacity, we can determine what a safe load is. The maximum thrust load that should be applied to the actuator while it is moving is known as a dynamic load. Dynamic load capacity refers to how much force an actuator can exert when driven and extending or retracting. With each method's benefits and drawbacks considered, it can be determined that using them in various situations and agreeing to the confrontation of these tests for the purpose of comparing results is the best course of action in order to have a base that satisfies the construction standards

The incorporation of thermal insulation materials into building walls is a novel strategy for reducing heating and cooling energy consumption. Nowadays, the issues of energy production, consumption, and energy storage have become global problems. Furthermore, the thermal insulation of buildings increases the thermal comfort of residential premises in order to save energy. The use of several kinds of thermal insulation materials is required in the construction sector. This paper compares the thermal and moisture performance of two different types of walls. The buildings taken under consideration are located in two different Tirana neighborhoods, close to each other sharing similar climate parameters. Depending on the presence of thermal insulation, two types of walls were taken into consideration. A wall in which thermal insulation is not present and a wall with a ventilated façade system, are considered. Thermal insulation in the second case is made with rock mineral cotton. In order to obtain the most accurate results, pertinent temperature and humidity, measurements were made at several spots along the walls. The comparative analysis was performed using special measuring instruments. The temperature and moisture level in the internal walls and the temperatures of the external walls, at various spots on the walls, were taken into consideration, along with the layers of the relevant walls in both cases. The aim of this paper is to experimentally study the thermal performance of walls with various types of thermal insulation, including the ventilated façade system, as well as walls without thermal insulation. The purpose of the study is also to show how the technical and architectural methods utilized during construction affect the moisture and temperature fluctuations of the perimeter walls.

Is it about energy?! This paper consists of the analysis of the construction of the Fierza's dam, built on the Drin river bed in 1978. During the study of the dam construction scheme and later during the design of the projects, various problems were taken into account, such as the geological conditions of the area where the hydropower plants were erected, the construction materials, the most suitable solution for the type of dam, the auxiliary works, their construction, sequence and time. For centuries, the world's water resources have been developed to benefit mankind. The construction of dams in order to create reservoirs has served many purposes. These are some common uses such as water supply, hydroelectric power, flood control, irrigation, and navigation. The dams are also used to regulate the flow of water in rivers. Water can be released from the reservoir during drier seasons to support wildlife and the environment downstream, and to provide a resource for human uses. Dams have long been viewed as a symbol of human ingenuity and among them is the Fierza's dam, one of the greatest achievements in Albania. During the period of the construction of the dam, Albania was in difficulty to finance the design and the implementation of such works that envisaged large dams. Regardless of everything, the small state of Albania managed to build magnificent hydropower works with great economic value and a high technical and scientific level, such as Fierza's hydropower plant. This paper aims to show the importance of the construction of Fierza's dam in the production of energy in the country with an annual average output of 1,330 GWh. Also, the importance of Fierza, besides energy production, relates to the capacity of its lake, which regulates the annual inflows, increasing the efficient use throughout the cascade.

This article presents information about facades, their thermal insulating role in buildings in Albania. The façade in construction is one of the necessary factors to ensure a longer life of the buildings and indoor thermal comfort. Façade systems are composed of different materials, which provide a protective effect during the life of the building. The article will focus on the characteristic materials used in Albania for the construction of facades and the main materials used from the year 2000 up to today. The article will be informative, statistical, and comparative in order to draw conclusions. Nowadays building facades are again becoming one of the main subjects of discussion, undoubtedly due to the increasing importance of the building envelope in relation to energy consumption. In the 90s, minimal attention was paid to the efficiency and quality of facades; everything was done strictly in relation to residency requirements. But, during this last decade, Albania experienced a construction boom, with a series of good new buildings, which are accompanied by progress in the architectural style and in the techniques of building materials usage. However, the advantages of façade systems in construction are not only to make the building long-lasting. The function of facades always undergoes changes and advances over time, in terms of their impact on the temperature fluctuations inside the building or energy storage.

This paper is going to deal with water absorption in different types of wood such as: pine, oak, beech, and fir. The amount of water absorbed by these types of wood is known as water absorption and it is determined using the material's initial state and after their immersion in water. The major goal of this study is to explain the effects of water absorption in hardwood materials and to demonstrate the changes that will take place in them over the course of 48 hours. Water can be absorbed by wood in a variety of ways, as a liquid, or as an atmospheric vapor. Despite the fact that wood can absorb other liquids and gases, water is the most important. Because of its hygroscopicity, wood, whether as part of a living tree or as a material, always contains moisture. The experiment will be focused on the selection of different types of wood (most popular in the Albanian context), analyzing their water absorption and moisture level. The wooden samples will be submerged in water for 24 and 48 hours in order to obtain the appropriate results. Their moisture level and water level due to capillarity will be analyzed too. The purpose of the study is to follow the behavior of wooden frames in different environments.

Extruded polystyrene (XPS) otherwise known as a thermoplastic polymer has a closed cell structure and is often stronger, with a higher mechanical performance. XPS is a pressed material and is sold in different thicknesses ranging from 2 cm to 10 cm, thus having a weight that varies from 28 to 45 kg/m3 due to the force and pressure exerted on it. In general, XPS material has very low thermal conductivity and is resistant to bending. This material obtains typical values of thermal conductivity between 0.025 and 0.040 W/m∙K., which means that it is ideal for surfaces that have to withstand weight, continuous traffic, etc. It is also resistant to moisture absorption and has a homogeneous density. Other characteristics of the material are good acoustic properties, easy assembly, and high durability over time. It should always be kept in mind that the surface where the thermal insulation will be applied must be leveled, cleaned, and dried. Primer is applied, before placing the thermal insulation on the surface. Then, XPS boards are placed on the surface, adhering to the corresponding mortar. This paper will deal with different cases of application of XPS tiles in the city of Tirana. A closer look at the resistance of this material from the day of application until today will be analyzed. The results during the observations showed high thermal stability of the material and no mold surface. EPS Expanded Polystyrene, otherwise known by the Dow Chemical trademark name STYROFOAM, is a lightweight product made from expanded plastic beads. It was first discovered by Eduard Simon in 1839 in Germany. EPS in its composition has 95% air and only about 5% plastic. This material is used because of its excellent properties, including good thermal insulation, good protective properties, and extremely lightweight. EPS is inert in nature and therefore does not result in any chemical reaction. EPS is durable, strong, and lightweight and can be used as an insulated panel system for facades, walls, roofs, and floors, as floating material in marine construction, and as a lightweight filler in road and railway construction. Different examples from the city of Tirana, of buildings where XPS and EPS materials are applied, are going to be analyzed, drawing conclusions.

The overwhelming majority of Albania’s urban population is located in Tirana, a city with a very dynamic socio-spatial reality, resulting as an entry point for people from various origins, including multicultural rural societies, and has significant concentrations of finance and other economic activities. Urban areas demonstrate the dynamics that impact society from many angles, including those related to technology, economics, demographics, and culture, via a diverse and changed perspective. Since 1991, there has been a growing separation between classes, genders, and regions, as well as between individuals and vulnerable groups, due to a lack of social protection and governmental measures for these groups and individuals, and the unrestricted power of the free market. Today, there is a noticeable improvement in the real pattern of social group concentration. This paper focuses on various divisions of social groupings in Tirana, how they are reflected in the city’s everyday life, and how they trend to the fragmentation of contemporary urban regions. In order to comprehend the change over time and transition patterns of Tirana from sites of production to places of consumption, the process method is modified by concentrating on the main stakeholders. The background of enhancing cities’ mobility and competitiveness demonstrates the interaction between different social groups and different living patterns in Tirana. The study also shows the socio-spatial pattern of the new city. The significant level of social fragmentation in Tirana is evident from analysis that only investigated a certain percentage of the city’s social groupings. The new master plans predicted in the city will help to overcome the issue.

The overwhelming majority of Albania’s urban population is located in Tirana, a city with a very dynamic socio-spatial reality, resulting as an entry point for people from various origins, including multicultural rural societies, and has significant concentrations of finance and other economic activities. Urban areas demonstrate the dynamics that impact society from many angles, including those related to technology, economics, demographics, and culture, via a diverse and changed perspective. Since 1991, there has been a growing separation between classes, genders, and regions, as well as between individuals and vulnerable groups, due to a lack of social protection and governmental measures for these groups and individuals, and the unrestricted power of the free market. Today, there is a noticeable improvement in the real pattern of social group concentration. This paper focuses on various divisions of social groupings in Tirana, how they are reflected in the city’s everyday life, and how they trend to the fragmentation of contemporary urban regions.

Structuralism can be defined as an important concept of using “units” as elements of form and space-giving, where the whole form is made not only up of a “texture”, a certain flexible grid, or an algorithm of shape-giving, but it depends also on the relationships created and how people use it. The hypothesis of this study is that “Modular Construction” can also have an aesthetically pleasing outlook and that modular housing can definitely have increasing importance in the future. Modular housing due to its cheap, and manufactural way of construction can be replicable in various locations. Structuralism and Modular Construction have been at the core of the Modernist movement. Although postmodernism marked the decline of modular construction adopting methods known for a more close sense of place, vernacular, and locality, which differs from the ubiquitous model of modernism, it is the universality of space and habitation seen since the times of Hippodamus Grid, Japanese Tattami systems, and rational universal space in housing known in Europe that make grid and modular design an excellent system in obtaining, rationality, functionality, flexibility, and energy efficiency, including quick construction and possibility for replication. In this regard, modular construction has a future, especially in times of crisis and economic instability.

The use of modular construction technology has emerged as a promising solution to the challenges of the construction industry all over the world. This paper examines the new horizons and opportunities that modular construction technology offers not only in the Albanian context but also in some European countries. The paper provides an overview of the status of Albania's construction market and emphasizes the advantages of modular construction technology, including quicker construction, lower costs, and better quality control. Unfortunately, prefabricated constructions are not very present Albanian construction industry, and it is not given the proper attention due to lack of infrastructure, organizational purposes, and lack of proper experience. The paper also examines the challenges associated with the implementation of modular construction technology in Albania, exploring the history of prefabricated constructions, also including regulatory barriers, lack of awareness, and the need for skilled labor. Finally, the paper concludes by suggesting strategies to overcome these challenges and promote the adoption of modular construction technology in Albania, such as targeted government policies, education and training programs, and partnerships between industry stakeholders.

The paper presents an analysis of the current state of administrative modular buildings and co-working spaces in some European countries and Latin America. The study provides an overview of the concept of modular buildings and co-working spaces, including their history and evolution and their energy efficiency. They also examine the benefits and drawbacks of these types of buildings, as well as the factors that contribute to their success. The authors analyze several case studies of administrative modular buildings and co-working spaces in different European countries and Latin America, such as the UK, Germany, Slovakia, and Ukraine ending with Brazil. The paper takes into consideration the design and construction of these buildings, as well as the services and amenities they offer. The paper also considers the impact of administrative modular buildings and co-working spaces on the environment, as well as their potential for promoting sustainable development. The authors discuss the challenges and opportunities associated with the development of administrative modular buildings and co-working spaces and provide recommendations for future research in this area. Energy-efficient modular buildings and co-working spaces have the potential to support organizations in achieving their sustainability goals while also providing a range of benefits for employees and stakeholders.

Hospitals must have adequate lighting so that medical personnel can do their duties and attend to the requirements of patients and visitors. A comfortable recuperation environment may be created with the aid of good lighting. The relationship between daylighting and artificial lighting and their role in the design process will be mentioned. Specific areas of the hospital will be under adequate lighting analysis. The areas taken into consideration are entrance and waiting areas, circulation areas, operating theatres and clean rooms, wards and bedrooms, ancillary areas, restaurant and kitchen, and exterior lighting. Some of these areas are also analyzed regarding the case study of the Military Hospital (University Trauma Hospital) of Tirana Albania. The purpose of this paper is to compare different lighting standards, the EU standards, and the Albanian ones. Solutions can be provided for lighting systems, starting from luminaries and lamps, to lighting controls and lighting management systems, from the early stage of design. The architect is the enabling partner to develop meaningful lighting solutions for all areas of healthcare facilities.

Albania is part of the emerging economies of the Western Balkan region. Polis University is one of the pioneering institutions in the field of architecture, built environment, and city sciences that represents innovative methodologies and concepts for educational and scientific purposes. Nowadays, many constructions in Albania involve a wide range of different materials. The building envelope is one of the main elements that provide protection from the outside environment but also the required thermal comfort for the inhabitants. The necessary balance must be archived between energy efficiency and the durability of buildings. This paper will focus on the thermal performance and materials composition of two different types of masonry walls, a constituent part of Polis University's main building. The study will be based on an experiment using specific instruments to diagnose these typologies of wall composition. The results are further analyzed and compared. Specific instruments such as the thermal camera (Testo 882), U-value(Testo 435-2), and “Silverline Digital Moisture Meter” (from POLIS Energy lab) are engaged. The collected data are further interpreted through graphs, tables, and diagrams for both cases. It is observed that ventilated facades perform much better than standard facades, therefore their usage is strongly recommended.

Cities and towns are expanding and thriving as a result of urbanization, which also significantly changes the local climate. One of the most significant phenomena associated with urbanization is the Urban Heat Island (UHI) effect. This phenomenon is increasingly being studied worldwide. The paper aims to investigate the UHI phenomenon in the metropolitan area of Tirana, Albania. It analyses the impact of the UHI on four specific locations in Tirana, its causes and mitigation measures, as well as variations in surface temperature, CO2 emissions, and relative humidity. The regions are measured and observed using a specific instrument such as the Testo 435. Considering the mean surface temperature variations between urban and rural regions ranging from 28.4°C to 33.7 °C, CO2 emissions from 302.9 ppm to 416.2 ppm, and relative humidity from 34.1% to 41.2%, it is found that the UHI impact in Tirana is significant. The lack of green spaces, high building density, urban patterns, building materials used, transport, and energy use are the main contributors to the UHI in central Tirana. Increasing green spaces, using reflective materials, and promoting sustainable urban design are some of the mitigation techniques suggested to reduce the UHI effect in Tirana.

Metaphor plays a central role in changing the architectural process. In order to better appreciate the nature of architectural creativity, generating more positive forms and volumes is required. Exists many conclusions which demonstrate that metaphors plays an important role shaping the design creativity. The aim of this paper is about understanding the exact role of the metaphor in architecture design from the concept of Aristotle to nowadays. Essentially it is the process by which most of the ideas come into being. Metaphors structure our understanding and perceptions. They make our thoughts more interesting and more vivid. There are similar distinct uses of metaphor in architectural criticism, which is often heavily reliant on metaphor both as a form of expression and a tool of analysis. There is a dimension of meanings attached to the various uses of metaphor, ranging from the ornamental view at one hand to the rational view at the other [1].Metaphors role in the ecological design is essential and necessary. Architects use a variety of methods and techniques to enrich the architectural language. This process is accomplished with the infiltration of metaphors as a literary figure. By adopting the models of nature, there is a chance to work more sustainably and produce more sustainable products. Is this the paradigm shift we have been looking for? Maybe biomimicry and nature could be super metaphors in order to develop sustainable design. This paper should take in consideration also the metaphor as a tool implemented into design reflecting either positive or negative reactions. This theory should be explained by concrete examples. The working metaphor in the design process is another important issue to be judged. The aim of this paper is to demonstrate that architectural metaphors corporate in coherent ways with architectonic language shaping its functionality. Metaphor helps to perceive things from a different perspective that is new to us, changing and bringing new ideas. Architectural metaphors can be found everywhere also in the Albanian case. It is very evident how metaphor stretches architectural functionality.
