The thermal behaviour of an office building is presented and discussed, as well as the results of a sensitivity study, which analyses the impact of architectural decisions and the effect of occupancy in terms of energy consumption (cooling and heating loads). This study was carried out using one floor of an office building, with large glazed facades, recently built in S. Paulo in Brazil, which was monitored for a short period (11 days)]. This building has been used as reference, for the sensitivity studies carried out for two climates, S. Paulo in Brazil and Lisbon in Portugal.
The Mosque of Cordoba is the best example of the Islamic religious buildings that survived in Spain. Its typology corresponds to a mosque of a large scale with the common plan of the early Muslim art. This model became an architectural reference for the mosques of Western Islam. The paper presents the results of measurements undertaken to assess the environmental performance of this building.
The buildings of this Environment Educational Center, designed with innovative energy saving features, minimize the impact on the preexisting environment. Renewable energy concepts have been applied to the building design, and intelligent control of lighting and air-conditioning has been included. Most of the buildings are green roof underground buildings, where domes that allow spans up to 42 m have been designed. Average energy saving is over 70% on heating and cooling demands and 60% in lighting.
Research and development of new-type passive solar houses are the main purpose of this paper. The proposed passive solar houses haven an air circulation system in brick walls combined with passive heating and cooling systems. A prototype model house with a solar collector and Trombe walls was constructed and its thermal performance was measured to evaluate this new system. The efficiency on the real size model house with attached green houses is discussed through thermal performance simulations.
The article describes experiments with wall-mounted air terminal devices. The airflow from an air terminal device influences the occupants' thermal comfort and, therefore, it is important to develop an expression for the flow in the occupied zone. The velocity at the floor is influenced by the flow rate to the room, the temperature difference and the type of diffuser. The flow is stratified at Archimedes numbers larger than four. The article gives expressions for the velocity distribution close to the floor.
This paper describes the measurements and evaluation of the indoor thermal environments in a large domed stadium. This stadium was built mainly for professional baseball games, but it has a lot of other purposes. It will be used not only for many sport games but also for various entertainment events. To satisfy such purposes, various intelligent mechanical systems were equipped to control and create a suitable space and environment without consuming excessive energy.
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
A recent European project explored combinations of radiative and evaporative cooling processes involving the roof for application in the Mediterranean region. The paper introduces the experimental applications which were built and tested as part of the project and the design considerations and applicability data derived from simulation models validated with the experimental results
