This paper shows the building of the Intelligent Energy Research Center - CPEI, built at the Federal Center of Technological Education of Minas Gerais (CEFET-MG). This center was conceived with many strategies of bioclimatic architecture in a way to minimize the energy consumption besides improving the thermal gain and luminous comfort. To achieve this purpose many procedures were taken since the beginning of the design stage. The architecture solution is very important to improve the thermal and luminous performance.
Climate of the Po Valley, in northern Italy, typically is hot humid during summer and cold during winter. In such region new house constructions are often defective in dealing, by passive means, with solar radiation and outdoor temperatures, the majority of new buildings is designed with light envelope, and no care is taken over many issues like solar control, albedo of external surfaces, natural ventilation strategies. The negative result is a substantial growth of electrical demand associated to housing cooling, since A/C systems are becoming cheaper and more popular.
The study that is being undertaken at the University of Porto, Portugal, aims at creating a decision tool, based on the appropriate ventilation strategies for the cooling of buildings in hot humid climates. The climatic conditions of the Amazonic region of Manaus are taken as an example of this type of climate. First, we have to identify every single architectural or climatic parameter related with the ventilation of indoor spaces and evaluate their impact on ventilation efficiency.
This paper presents a simulation case that shows the impact on energy consumption of a building applying photovoltaic shading systems. In order to make photovoltaic application more economical, the effect of a photovoltaic facade as a passive cooling system can result in a considerable energy cost reduction, with positive influence on the payback time of the photovoltaic installation. Photovoltaic shading systems can be applied to both refurbishment of old buildings and to new-build, offering attractive and environmentally integrated architectural solutions.
In this paper the effect of insect screens and vent configuration of a tunnel greenhouse cultivated with a tomato crop on airflow, temperature and humidity patterns was numerically analyzed using a commercial computational fluid dynamics (CFD) code. The numerical model was firstly validated against experimental data, which were carried out in an arch plastic covered greenhouse with continuous side openings. The three components of air velocity and the spatial distribution of air temperature and humidity were measured using a sonic anemometer and fast response sensors respectively.
This paper deals with the use of computer simulations both for design support of a new building including its heating, ventilation and airconditioning (HVAC) systems and for optimization of the HVAC control strategy during operation of the completed building. In the early design phases for a new commercial building in Prague computer simulations were carried out in view of possible effects of night cooling ventilation.
Environmental and natural phenomena play a very significant role in laying the region's interrelated cultural, economic and social infrastructures. The buildings in the Iranian desert regions are constructed according to the specific climatic conditions and differ with those built in other climates. Due to lack of access to modern heating and cooling equipment in ancient times the architects were obliged to rely on natural energies to render the inside condition of the buildings pleasant.
Providing optimum cooling and heating of residential buildings of hot and dry regions in Iran so far has been according to the relations of ecology, so that using architectural methods based on climate, local materials and also culture has damaged the environment as little as possible.
This paper’s aim is to present a building design case study in a Mediterranean urban environment using as main assessment tool, a comparative dynamic thermal and daylight computer simulation. The scope is to describe the methodology based on which the sim
The study of thermal environment around buildings is of great importance for residential microclimatic conditions. Temperature of external building surfaces, ground and outside air as well, affect the sense of thermal comfort for a person sitting outside a house. The microclimatic components that can be modified through design and that strongly affect thermal comfort in the open areas close to the buildings is sun radiation and thermal radiation emitted by the surrounding objects.
