In the previous study, it was found that urban heat island intensity in National University of Singapore (NUS) campusas high as 4oC at around 13:00. It is also concluded that the presence of dense greenery in NUS environment is very important in keeping low ambient temperature.National University of Singapore has announced its new master plan in 2005, entitled NUS Master Plan 2005. Many new buildings will be built and in some areas existinggreenery will be removed.

The objective of this work is to compare the thermal behaviorof two systems of beam ceilings used in the Collegeof Architecture of the Independent University of Chiapas - Mexico. The beam ceiling base (show room) is of reinforced concrete with 10 (ten) centimeters of thickness that will be reference for comparative degree how much to the internal temperature of air in relation the construction covered with developed technology of in the College of Architecture of the UNACH that has water blade of 15 (fifteen) centimeters of thickness.

The European research project “EULEB – European high quality Low Energy Buildings” intends to provide information about good examples of energy efficient buildings in use, in order to reduce prejudices and lack of knowledge of many key actors of the build

Illuminance and daylight availability are important parametersin daylighting design for passive, low energy architecture. In Malaysia, the only climatic parameter that can be used for determining daylight availability is global solar irradiation, which is measured at major meteorologicalstations around the country. However, it is possible to estimate the global illuminance from global solar irradiation data if the global luminous efficacy is known.

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.

“Energy Towers” is the name of a technology which was developed at the Technion--Israel Institute of Technology, to produce electricity in arid lands, taking its predicament - a lot of hot dry air - and turning it into an asset. “EnergyTowers” is an econo

The energy rehabilitation of listed buildings is of great importance as they are many limitations of the possibletechnical interventions. The paper presents the outcomesof a study concerning the possible interventions in an existing building focusing in the minimization of the energy consumption and the achievement of the desirablethermal and visual comfort.The building is located in the centre of the city of Athens,Greece with total heated area of approximately 896m2. The building has areas with different use, such as offices, seminar room, and restaurant.

The paper reports on a series of short projects undertaken in the course of the 2006-07 academic year as part of the AA School’s Masters Programme in Sustainable Environmental Design. The objective was to explore the architectural potential of adaptive co

The goal of this study was to suggest a low-density typologyfor commercial buildings to be applied in the cultural and climatic context of Athens, Greece, with minimal demand for conventional cooling. More specificallya typology of double enclosure was studied with self-contained structures sheltered within an outer shell. The research develops through studies of built examplesin Athens and analysis of the parameters affectingthermal comfort and adaptability. Dynamic thermal simulations were used to gain understanding of the energybehaviour of the double enclosure typology.

The paper provides a technical discussion on the developmentof zero energy building design strategies in the UK. Two building simulation software (TAS and TRNSYS) are employed to investigate various facade parameter studies as well as a solar service system. TAS building simulation is used to assess the effectiveness of passive strategies by taking building materials, window sizes and shading devices into consideration. TRNSYS is used for the investigation of the feasibility of using solar domestic hot water system in UK.
