The present study intended to evaluate thermal comfort conditions in microclimates of the urban historical areas of Isfahan, Iran during a heatwave. The thermal comfort conditions of different historical sites were compared during the daylight hours to determine the best time to visit each historical site. Using the results of this study, tourists...

The growing interest in thermal comfort of outdoor environments yields in different analysis on courtyards as a common space between urban and architectural scales. However, there is a limited knowledge regarding the microclimatic behavior of such spaces. Using ENVI-met simulations, this paper aims to numerically discuss the thermal performance of...

Daylighting is a passive strategy which is significant in increasing the liveliness, performance, and visual comfort of the residents. It helps to reduce the overall electrical energy consumption of a building. The absorbed radiation by the façade and building interior varies depending on different factors including the sky, environmental barriers,...

This research aims to demonstrate a model of Double Skin Facade (DSF) that functions efficiently in hot and dry climates. Knowing that DSF performs well in winter at hot and dry climates as thermal mass is needed. However, this method during summer evinces overheating between the two skin layers. This paper introduces some modifications in order to...

Assessing sunlight conditions in urban environments is crucial, as high-quality natural light is essential for human health and well-being while supporting the production of clean and affordable energy. This systematic review examines the current state of research on solar access in urban and neighborhood contexts, identifying key variables and the...

The quality of thermal environment in outdoor spaces greatly affects pedestrians' health and their reaction to microclimatic conditions, ultimately influencing their likelihood of spending time in those areas. The significance of these issues in urban environments has prompted worldwide research on microclimates and outdoor thermal comfort (OTC), e...

Over the past two decades, global greenhouse gas emissions have surged, leading to rising sea levels and climate change. Solar energy has emerged as an excellent solution to this problem. This study aims to assess daylight availability and energy consumption in urban canyons and blocks in a semi-arid climate while exploring the correlation between...

Proper sunlight access has a positive impact on the physical and mental health of citizens, as well as on reducing energy consumption. This capacity may be limited by inappropriate urban morphology, and urban canyons and buildings are deprived of proper daylight. The purpose of this research is to study the current solar potential on the surface of...

The importance of climate change mitigation and energy efficiency as a growing global concern has intensified the development of techniques to reach and improve thermal comfort and energy efficiency of buildings. The study of the effect of the height of the openings on the internal natural airflow in one-story buildings can be found in many studies...

Reducing the pollution concentration on the urban street ventilation is significant for creating a healthy urban living environment. In this study, the effects of source location on airflow patterns and pollutant transmission in street canyons under the influence of wind and thermal buoyancy forces have been investigated using the CFD approach. Als...

The increasing urban population of the world highlights the importance of urban public spaces, including urban green spaces. Many studies revealed the health benefits associated with being in constant connection with urban green spaces. Thermal comfort is one of the factors that can affect being benefitted from the green space. Green space motivate...

This study investigated the role of urban geometry and urban shading in improving the pedestrians’ thermal comfort in hot climate of Ahvaz, Iran. Six urban canyons are selected in Ahvaz. To determine the outdoor thermal comfort range, micrometeorological measurements and questionnaire survey were conducted in July 2018. ENVI-met is used to investig...

Thermal comfort is one of the main factors affecting pedestrian health, and improving thermal comfort enhances walkability. In this paper, the impact of various strategies on thermal-comfort improvement for pedestrians is thoroughly evaluated and compared. Review studies cover both fieldwork and simulation results. These strategies consist of shadi...

Natural ventilation and cooling have played an essential role in providing comfort conditions. Windcatchers are passive cooling systems and one of the most familiar elements in Iranian architecture. They can significantly influence on reduce cooling loads and supply the necessary ventilation rate of buildings. This paper aims at providing an in-dep...

p>Designing urban facades is considered as a major factor influencing issues such as natural ventilation of buildings and urban areas, radiations in the urban canyon for designing low-energy buildings, cooling demand for buildings in urban area, and thermal comfort in urban streets. However, so far, most studies on urban topics have been focused on...

Natural ventilation is application of natural drift power of wind. Wind can enter and exit buildings through the openings on facades. Hence, Form of facades can impact the air flow behaviour and consequently natural ventilation because they can change the pressure distribution on facades. Moreover, difference between wind-induced pressure on windwa...

Buildings and its surrounding environment contribute to producing greenhouse gases associated with more pollution and creation of urban heat island. Residential buildings have a major part in energy consumption, resulting in wasting natural and renewable energy. For this reason, optimizing the energy usage for housing is vital. The most critical pa...

Urban geometry is defined by the height, length, width, and distance of buildings, which affect the urban environment and its microclimate, especially a high-rise and high-density urban environment, such as Tehran. In this regard, the Sky View Factor (SVF) may often be a desirable criterion in identifying the interaction between urban geometry and...

Green systems, as green fecades and green walls, are often used as a well-known beauty feature in buildings. However, they can have many benefits such as environmental and economic and social benefits. Vertical green systems can be a sustainable solution for new buildings and rebuild existing buildings, in order to reduce energy consumption for coo...

Soil is among the cheapest and most available materials found in the human living environment. Seeking refuge in the heart of earth and benefitting from soil's thermal property, based on experience, is a strategy employed in the past across some regions. Also the passive systems are amongst the cheapest methods of providing heating and cooling dema...

یکی از مهم ترین مسائل که ممکن است در طراحی و برنامه ریزی ساختمانها در نظر گرفته شود، هماهنگی با طبیعت و اقلیم منطقه و بهره گیری از پارامترهای آب و هوایی از قبیل نور و روشنایی طبیعی، جریان هوا و ... می باشد.کاهش مصرف انرژی الکتریکی و روشنایی مصنوعی روشی موثر در بهینه سازی مصرف سوخت می باشد، چراغ ها و لامپ ها با تولید گرمای همزمان با روشنایی عامل مهم...

Atrium refers to an open interior space that can be potentially related to an exterior environment. Indeed, atrium is considered as a filter and obstacle blocking undesirable exterior environmental phenomena such as rain, snow and wind. A well designed atrium can contribute to have a significant effect on both; the building's energy performance and...
