Abstract and Figures

Global environmental problems are one of the most critical problems of humankind. Increasing energy consumption and CO 2 emissions are among the most important causes of global environmental problems. The existing building sector is vital in increasing energy consumption and CO 2 emissions. Buildings are responsible for 30% of greenhouse gas emissions and about 40% of energy consumption. Energy used for heating and cooling is one of the most important causes of energy consumption in the building sector. Reducing the energy used for heating and cooling is possible with sustainable building design. One of the most essential criteria of sustainable building design is using passive air conditioning strategies. Traditional architecture is a crucial guide for using passive air conditioning elements. This paper presents an architectural taxonomic proposal for passive cooling strategies used in traditional architecture in hot and dry climate areas of the globe. The aim is to facilitate and simplify access to all cooling strategies and provide a guide for their adaptation to modern architecture. A total of 55 passive cooling strategies were identified in the research. Within the taxonomic proposal's scope, the strategy was first divided into four groups: settlement scale, building scale, space scale, and building environment scale, depending on the usage criteria. Then, this grouping was split into 16 subgroups. A taxonomic proposal was created by considering the intended use of the identified strategies. The findings indicate that although traditional architecture in hot and dry climates primarily focuses on heat protection and heat dissipation is also highly utilized. It has been determined that thermal insulation, shading and natural ventilation cooling strategies come to the fore. In addition, it has been determined that approximately 50% of the strategies used for cooling purposes are related to thermal insulation, shading, and natural ventilation. The taxonomic proposal guides modern adaptations in the built environment by combining traditional passive design strategies and simplifying their use. It can also be adapted to different climates and contribute to creating new modern building design guidelines.

Abstract
Global environmental problems are one of the most critical problems of humankind. Increasing energy consumption
and CO2 emissions are among the most important causes of global environmental problems. The existing building
sector is vital in increasing energy consumption and CO2 emissions. Buildings are responsible for 30% of greenhouse
gas emissions and about 40% of energy consumption. Energy used for heating and cooling is one of the most
important causes of energy consumption in the building sector. Reducing the energy used for heating and cooling is
possible with sustainable building design. One of the most essential criteria of sustainable building design is using
passive air conditioning strategies. Traditional architecture is a crucial guide for using passive air conditioning
elements. This paper presents an architectural taxonomic proposal for passive cooling strategies used in traditional
architecture in hot and dry climate areas of the globe. The aim is to facilitate and simplify access to all cooling
strategies and provide a guide for their adaptation to modern architecture. A total of 55 passive cooling strategies were
identified in the research. Within the taxonomic proposal's scope, the strategy was first divided into four groups:
settlement scale, building scale, space scale, and building environment scale, depending on the usage criteria. Then,
this grouping was split into 16 subgroups. A taxonomic proposal was created by considering the intended use of the
identified strategies. The findings indicate that although traditional architecture in hot and dry climates primarily
focuses on heat protection and heat dissipation is also highly utilized. It has been determined that thermal insulation,
shading and natural ventilation cooling strategies come to the fore. In addition, it has been determined that
approximately 50% of the strategies used for cooling purposes are related to thermal insulation, shading, and natural
ventilation. The taxonomic proposal guides modern adaptations in the built environment by combining traditional
passive design strategies and simplifying their use. It can also be adapted to different climates and contribute to
creating new modern building design guidelines.

Natural ventilation cooling: In traditional architecture with hot and dry climates, streets were generally
narrow and high in the north-south direction. This usage ensured that the streets were usually shaded.
The junctions of the streets receive more solar radiation, while the narrow side streets have a higher
shading ratio. This temperature difference between the streets creates a pressure difference and thus
provides ventilation and cooling (Fernandes & Da Silva, 2007; Kamal, 2014).

Courtyards provide shading by blocking solar radiation on hot summer days (Algburi & Beyhan,

The working principle of courtyards for ventilation and cooling depends on air movements.
During the daytime, the courtyard air, heated by the interior spaces and direct solar radiation,
rises and is expelled towards nighttime, while the cold air outside settles in the courtyard. The
settled cold air is used to cool the surrounding rooms the next day (Algburi & Beyhan, 2019;
Almatarneh, 2013; Edwards, Brian; Sibley, Magda; Hakmi, Mohammad; Land, 2006; Fathy,
1986; Koch-Nielsen, 2007; Mohamed, 2015; Reda Abdallah et al., 2020)

The courtyards provide thermal insulation as they are the buffer zone between the space and the
external environment.
Evaporative cooling is also provided in the integration of courtyards with water. An example of
this is the use of a pool in the courtyard or wetting the floor (Fig. 11) (Erdemir, 2014; Hailu et
al., 2021)

Roof openings provide ventilation depending on the buoyancy effect. During the night, cold air from
the outdoor space can settle into the indoor space due to the reverse buoyancy effect. During the daytime,
the air heated indoors rises and is expelled (Bahadori & Haghighat, 1985; A. Heidari et al., 2017;
Mohamed, 2015; Özdeniz et al., 1998; Reda Abdallah et al., 2020; Shaikhli & Shafie, 2020; Singh et
al., 2011). Roof openings have been used differently in different regions depending on the type and form
of use. The "a yi wang" used in the Uyghur, Gansu and Ningxia regions of China (Liu et al., 2006; Xuan
& Lv, 2017), the "chebbek" used in the M'zab region of Algeria (Aydeniz & Fellahi, 2019; Bensayah et
al., 2019), "khishkhan" in Yazd, Iran (Sahebzadeh et al., 2017) and "kolak" in Sistan (A. Heidari et al.,
2017) (Fig. 19).

Glass type: Glass coated with colored and various patterns provides insulation in traditional architecture.

5. Conclusion
The present study analyzes the purpose, form, and interrelationships of passive cooling strategies used in traditional
architecture with hot and dry climates. In this context, a taxonomic proposal is presented. The main aim is to simplify
the usage characteristics of passive cooling strategies used in traditional architecture with hot and dry climates and to
facilitate inspiration for interpreting their modern versions. Combining and simplifying these strategies will help
understand their use and priorities in contemporary architecture.
In the study, all strategies are categorized into four main groups: settlement scale, building scale, space scale, and
building environment scale. The identified strategies were subdivided into subgroups depending on their use, and
their intended use was determined. Many passive design strategies have been developed for indoor cooling in
traditional architecture with hot and dry climates. These strategies have been applied at different scales according to
the type and purpose of use. Although the scales are different, most of them work in conjunction with each other. In
addition, the strategies are usually designed for more than one purpose. Heat protection is at the forefront of this
climate architecture, and heat dissipation is utilized extensively. In this context, natural ventilation, cooling, shading,
and insulation come to the fore. The strategies used for these purposes are interrelated. In this study, combining
traditional passive design strategies is a guide for modern adaptations. The following recommendations can be
presented for sustainable building design in this context.

... It is well-known as the "industry of 40 %" [3], and one of the most energy-consuming industries and accounts for around (29 %) of worldwide energy consumption [4]. The construction methods still lack effective proposals for reducing energy consumption [5], resulting in buildings with high energy expenditure throughout their entire life cycle and, consequently, a large ecological footprint, and high operating costs [6], taking into consideration the expected global changes, which could increase the cooling and heating energy demands by (83 %) by 2050 [7]. Awareness of energy efficiency in buildings over the operation phase is increasing worldwide since this period is responsible for most energy consumption for heating, cooling, lighting, and hot water equipment [8]. ...
... The analysis of sequences with low impact on increasing energy efficiency of the case study is presented in Fig. 6. The effect of the examined factorial designs on energy efficiency compared to the best EUI value in Rio de Janeiro, Fig. 6, varies between (7,91 %) in sequence (5), and (10,17 %) in sequences (11 and 12). It can be observed that using the base model of the building design for the façade and roof could increase the EUI value by (8,47 %) within the North orientation; (9,04 %) within the South orientation; and (10,03 %) within the East and West orientation, respectively. ...

Buildings are distinguished by their high energy demand over their lifespan. Iimproving energy efficiency in buildings necessitates mitigating the operation energy performance by evaluating more sustainable building components such as green infrastructures. The novelty herein is to conduct a BIM-based parametric energy analysis of green building components for the roofs and facades, taking into consideration the climate classification and orientation of the building. The proposed framework of this study uses Autodesk Revit software and Autodesk Green Building Studio as BIM tools, and Minitab software as a parametric analysis tool to estimate the energy performance of several alternative components based on Energy Use Intensity (EUI) and Annual Peak Demand (APD). A case study of a residential building is examined in four cities within different climate zones in Brazil; Rio de Janeiro (climate zone 08), Macaé (climate zone 05), Petrópolis (climate zone 03), and Nova Fri-burgo (climate zone 02). The base model design of components of the building includes a reinforced concrete roof and ceramic masonry façade. The utilized alternatives are roof components (i.e. green roofs and expanded clay roofs), and green façade. This work insight using green façade for all elevations and green roofs to enhance energy efficiency in terms of EUI by (10,17 %) in Rio de Janeiro, (6,67 %) in Macaé, (11,43 %) in Pertópolis, and (16,43 %) in Nova Friburgo. While the efficiency in terms of APD would be about (28,07 %) in Rio de Janeiro, (22,79 %) in Macaé, (21,67 %) in Pertópolis, and (12,58 %) in Nova Friburgo. When the construction project is designed to install a green façade to the main elevation only, this work recommends using green roofs rather than the expanded clay roof or the base model design roofs to increase energy efficiency in such types of buildings. This work contributes to integrating green building components into building designs to improve energy efficiency and empower decision-making and sustainability in buildings.

The building sector is among the most critical factors affecting environmental sustainability due to its impacts, such as energy consumption and greenhouse gas production.The reasons for energy consumption and greenhouse gas production in the building sector may vary according to climatic characteristics. In hot and arid climate regions, a significant portion of energy consumption is caused by indoor cooling, especially since the focus is on reducing the indoor temperature. In the periods when traditional architecture was developed, the lack of technological products that would increase energy consumption was effective in providing indoor air conditioning with passive design strategies. This study aims to identify the building openings for natural ventilation and cooling used in the traditional architecture of hot and dry climates and to analyze and evaluate their modern interpretations. A total of 235 award-winning projects were analyzed, and 21 were included in the study. In this context, it was determined that 16 different strategies used in traditional architecture were re-interpretation, and their modern interpretations were analyzed through award-winning projects. The traditional passive design strategies identified in this context have been adapted to modern architecture in 18 types. Wind orientators come to the forefront. In addition, it was determined that the strategies adapted to modern architecture are generally integrated. This study guides modern interpretations of traditional passive design strategies for sustainable building design

Climate change is one of the most significant threats facing the world today. Buildings are one of the largest energy consuming sectors in the world. Most contemporary buildings are highly dependent on air conditioning systems and electricity, reliant on fossil fuels and increasingly unable to adapt to a warming climate. Iran's hot and cold climatic regions are vast, and significant amount of energy is consumed in these areas for heating, cooling, and ventilation. However, in the same climatic conditions in the past, numerous effective strategies had been used in vernacular residences to confront the harsh circumstances. Traditional buildings in Iran have employed some ingenious passive techniques especially in hot regions in order to restore thermal comfort and coordinate with the local environment and climate. A comprehensive overview of Iranian vernacular architecture principles, in addition to comparative analysis of its elements, shows the dominant effects of natural environmental factors. It is important to note that Climatic issues are considered as the most significant factors in architectural design and have an important influence on architectural development of Iran. These creative passive techniques have a high potential for today's architecture getting revived to decrease the fossil energy consumption. The main purpose of a research is describing and analyzing the principal and methods of vernacular architectural designs in Shavadan and Shabestan and also sunken garden which are kind of underground and semi-undergrounding building in dry and hot area. The three case studies analyzed in this paper could increase designer's awareness toward environmental sustainable contemporary architecture.

Modern buildings are associated with a lot of shortcomings, such as consumption of an excessive amount of non-renewable energy and resources, environmental pollution and depletion of natural landscapes, etc. Vernacular buildings can be argued to help in reducing environmental problems for local society. Libya, as a developing Arab country, has also faced several urbanization problems in recent years. However, the country has a remarkable span of vernacular architecture patterns. Vernacular architecture that the country owns may be a solution to combat such challenges. There are three types of traditional vernacular dwellings in three regions of the country as underground housing (the mountain region), compact dwelling (the desert), and the courtyard house (coastal region). Thus the aim of this study is to make a comparison between underground and modern housing in Gharyan, Libya, with regards to thermal performance and humidity. Thermal performance in both underground and above ground houses was measured with an instrument called a hygrometer. The result from the thermal measurement that was done in one month of the winter season (21/01/2019-18/02/2019) demonstrates that the underground house has an indoor mean temperature and humidity of 16.12°C and % 62.07 RH while the other house type has an indoor temperature and humidity of 12.70°C and % 70.13 RH. The underground house seems to have a relatively reasonable and stable indoor temperature compared to the modern house indoor. In addition, the underground house seems to be relatively less humid compared to the modern house for indoor environment in particular.

Buildings contribute to environmental problems due to unrestrained consumption of energy and other natural resources during the construction, maintenance and operation of the buildings. Hence the interest on reducing emission of greenhouse gases, caused by fossil fuels to power the cooling and heating requirements of the buildings has stimulated the interest towards climate conscious designs of buildings. The traditional buildings of the past constitute outstanding evidence of being climate responsive architecture. In this paper the author has tried to evaluate various climate responsive passive design features that have been employed in the traditional architecture of Jeddah in hot and humid climate. Mashrabiyas as climatic modifier has been laid emphasis upon. Further, a case of King Abdullah University of Science and Technology (KAUST), a contemporary design paradigm which integrates innovative strategies borrowed from traditional architecture of Saudi Arabia has also been studied.

Sustainable architecture is a key approach for creating sustainable cities and reducing the impact of climate change. In hot, arid regions, the passive design traditional architecture is known for its ability to provide comfortable indoor environments and outdoor shaded areas, in contrast to the use of energy-intensive air conditioners in a great deal of modern architecture. Thus, this research used a qualitative methodology based on ENVI-met software to study, investigate, and compare the thermal performance of two urban fabrics as case studies (traditional and modern districts) in the hot, arid climate of the United Arab Emirates. The thermal performance of the old urban districts was better than the new ones, with a lower maximum potential air temperature and an improvement in the level of thermal comfort, measured by a predicted mean vote. Moreover, it was found that enhancing the shade in the outdoor open areas in the modern district, mimicking the traditional passive design solutions, resulted in lower air temperature and PMVs. This research is expected to be one step among many towards creating sustainable, innovative modern architecture.

In Iranian architecture, the emphasis on the use of geometric ratios such as human scale and modularization, caused beauty and harmony. Unfortunately, in contemporary architecture, the use of these scales has been forgotten, and their presence has been diminished. Therefore, the main goal of the present study was to analyze and evaluate the geometry and proportions used in six remaining traditional Iranian sunken courtyards in Yazd and Kashan. For each house, the length, width, height and the ratio between these dimensions were measured for the sunken courtyard, courtyard and earth of the case studies. Then, to find out which kind of proportions were used in these sunken courtyards, we proposed some statistical tests to compare our measurements with the traditional proportions used. In the end, the results showed that the proportions used in the design of the sunken courtyard, courtyard, and earth of the case studies are related and the traditional Iranian sunken courtyards have been designed mostly based on the use of Gereh (a unit of measurement), which was the most appropriate and most widely used scale in housing architecture.

Encyclopedia of Energy Engineering and Technology, Second Edition ISSN: (Print) (Online) Journal homepage: http://www.tandfonline.com/doi/book/ Abstract In response to challenging harsh climatic conditions, man has always been searching for habitable dwellings that offer thermal and visual comfort, security, and peace with the available natural resources such as sunlight, wind, and earth. Climate-responsive architecture has existed for many centuries in various regions with a hot-dry climate as a solution to constraints imposed by local climatic conditions. Building practice incorporates diverse passive design strategies to protect inhabitants from the surrounding hostile environment and provides maximum indoor comfort with minimum energy consumption. These strategies are based upon site selection, planning and layout of settlements, building components design, envelope design, incorporated passive elements, and lifestyle adapted. Although there are now technical means that would allow building design to ignore the climate, there are still good reasons to adopt passive techniques, not only for economy reasons but also to promote environmental sustainability at both local and global levels. This entry aims to give an overview and a comprehensive understanding of the vernacular architectural practices to withstand the harsh climatic conditions of hot-arid lands. It recognizes lessons from the past of having to live sustainably in a passive manner and thereafter pays full respect to a complexity of settlements, their urban dynamics, need for environmental adaptation to hot and arid climate, as well as ingenious solutions on all levels at the urban scale.

In this study, academic staff residential buildings were studied as part of a university campus located in a hot and humid climate zone in Türkiye. Within the scope of the study, the energy efficient architectural and landscape design decisions of the buildings built in 1976 were examined. The aim was to determine the energy performance of buildings built about 50 years ago and to quantify the effect of changing landscape conditions on thermal comfort. In this aim, the outdoor thermal comfort level was determined by creating microclimate simulations for the hottest day and time of the year. Microclimatic analyses were performed with ENVI-met software and thermal comfort was evaluated with two metrics, average PMV and ASHRAE scale. The energy performance of the buildings was determined using ecological design parameters. An approach to global environmental problems is the use of ecological design principles, including architectural and landscape design principles. It is important to consider both architectural design criteria and landscape design criteria when discussing ecological design in the built environment. Architectural and landscape design decisions for hot and humid climate regions together increased energy efficiency by 51.1% to 75.5%. It was found that although the plant design improves energy performance in buildings by that range value, it improved outdoor thermal comfort by 15% to 22%. As a result, the study evaluated climate-balanced plant design with building energy performance in order to improve outdoor thermal comfort.
