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.
The objective of this paper is to show the importance of the solar passive design principles in Antonio Gaudi’s Architectural Work from the analysis of one of his domestic buildings constructed in Barcelona in the turn of the XX century: The Batlló House.
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
In the last years, the terms “ecological, sustainable, green” have been used and abused, also in buildings and settlements design. Further, usually, “ecological” aspects are not yet effectively integrated in the design laboratories of architecture and tec
During the summer, the materials, which are used in the “skin” of Greek cities display very elevated surface temperatures. These high temperatures largely affect thermal comfort conditions in the urban open spaces and the development of the urban heat isl
Urban areas tend to have higher air temperatures than their rural surroundings as a result of gradual surface modifications that include replacing the natural vegetation with buildings and roads. The term Urban Heat Island describes this phenomenon. The surfaces of buildings and pavements absorb solar radiation and become extremely hot, which in turn warm the surrounding air. Cities that have been paved over do not receive the benefit of the natural cooling effect of vegetation. As the air temperature rises, so does the demand for air-conditioning (a/c).
