Ventilated courtyard as a passive cooling strategy in the hot desert climate

Traditional architecture gives ideas to enrich modern architecture. In traditional architecture, local materials and renewable energy resources have been used. The courtyard was one of the traditional architecture solutions as a climate modifier. The inclusion of an internal courtyard in buildings design is attributed to the optimization of natural ventilation in order to minimize indoor overheating conditions.

Environmental effect of courtyard in sustainable architecture of Iran (Hot-arid regions, meso-climate BWks)

This paper concentrates on the results of sustainability caused by Courtyard as a climatic element in Iranian traditional architecture of hot-arid regions. Traditional architecture of Iran is perceived sustainable for having sustainable features. It is able to response to environmental problems from a long period.

Environmental effect of courtyard in sustainable architecture of Iran (Cold regions)

This paper concentrates on the results of sustainability caused by Courtyard as a climatic element in Iranian traditionalarchitecture of cold regions. Traditional architectureof Iran is perceived sustainable for having sustainablefeatures. It is able to response to environmental problems from a long period. Its features are based on climatic factors as well as local construction materials of cold regions and Courtyard (hayate- markazi) is one of this features .Courtyard as one of the determining and organizing factor of traditional architecture in cold regions involves varies aspects.

A thermal comfort survey of courtyard housing in Iran.

This paper describes a thermal comfort survey of people living in courtyard housing. The study took place in the Iranian city of Ilam, which experiences a hot, dry climate. The survey compared the thermal comfort conditions of people outside using the courtyard housing, and was conducting during the hot summer season. Over 570 subjects responded to thermal comfort questionnaires. At the same time physical measurements were taken of such parameters as dry bulb air temperature, relative humidity and air velocity.

Courtyard microclimate: a hot arid region case study.

This paper examines the conditions of a relatively large courtyard (45 by 10 meters), enclosed by a one-story building, located in the Negev Lowlands. The region is characterised by hot, dry summer days, and wide temperature and relative humidity fluctuations. The courtyard was monitored under extreme conditions typical of the hot spells, common during transition periods, during which even night minima are sometimes well above the comfort zone.

Natural ventilation characteristics of courtyard buildings in Singapore.

Researches into natural ventilation characteristics of courtyard buildings have been carried out extensively in climates very different from tropical climate. Nevertheless, courtyards have been incorporated for centuries in traditional shop houses and also adopted in many modern commercial buildings in tropical countries such as Singapore. This paper discuses a study to investigate the natural ventilation characteristics of courtyard buildings in Singapore. Four typical courtyard buildings are examined.

Natural cooling in Hispano-Moslem residential architecture: the case-study of the Court of the Lions and the Court of Comares in the Alhambra (Granada).

The XIV-century Palaces of the Lions and Comares constitute the principal residential complex of the Alhambra in Granada. Both are distributed around gardens enclosed in courtyards, originally with abundant vegetation and water. This paper includes a series of measurements carried out in the rooms and the courtyards in order to contrast the different microclimates, as well as some solar-penetration diagrams. It also focuses on the analysis of the Hispano-Moslem residential type in relation to ifs environmental performance

Wind driven and thermal air flow patterns at courtyards.

Air flow patterns and temperature distribution within courtyard have been studied. Wind and thermally driven flow have been thoroughly analysed as a function of the depth to width ratio (Aspect ratio) as main parameter. CFD results show a quite similar behaviour regarding to velocity profiles for all the cases, though temperature profiles are highly affected by dimensions of the courtyard. The whole study can be extrapolated to urban canyons, where air flow patterns are quite similar as a result of having the same geometry.

Air flow pattern in courtyards.

The relationships, in courtyards, between wind flow pattern and temperature distribution have been studied. Thus, in the first part of this study a dimensionless temperature based on the exchange of heat by convection is defined. Then, using the ratio of depth to width (Aspect Ratio) as the main parameter, we are able to explain the curious behaviour observed. Finally, courtyards are divided into several zones in order to separate the different heat sources in each one, allowing us a stratification study.

Air flow simulations in a place dedicated to meditation. The Cistercian Cloister.

Confronting the high density of town planning, architects and towr1 planners are led to design mall outdoor places which are inserted into the city but offer specified properties: serenity, calmness, unusual surrounding ... Within the framework of the CERMA laboratory, we are looking for reference architectural examples likely to meet such needs and transposable into a contemporary architectural project.
