A bioclimatic house for Tamare, Venezuela, designed to provide psychological, physical and social well being through improved comfort and less energy consumption is explained. Digital and analog models were built to analyze sunlight and shadow behavior and computer simulations to predict thermal performance. Assuming a maximum comfort temperature of 30° C we achieve<! 95% of satisfaction when we ventilated at night and closed the building during daytime.
The examination of the "Young-am House", a traditional folk house located in the middle region of the Korean peninsula, aims to analyze and to inform the bio-climatic design of the building and interior spaces based in the traditional architecture of Korea. As a consequence of the examination, it was evident that bioclimatic design performed an important part in creating a natural environment for comfortable living by taking consideration of the changing local climatic conditions.
In equatorial warm humid climates, ventilation has been largely adopted as a major strategy for natural passive cooling. In those climates the use porous elements are common to allow for permanent ventilation as temperature rarely drops below 20°C. Nevertheless, the performance of many building components has not been thoroughly determined, making it difficult to predict buildings performance as ventilation rates, estimated in most simulation codes are often based on apertures typologies from temperate and cold regions.
Studies at the Oxford Brookes University have shown that opportunities for improving a building's fabric thermal storage performance relate more to aspects of its configuration, control and ventilation strategy than the choice of structural system.
Air movement in a naturally-ventilated room can be induced through the use of a solar chimney or Trombe wall. In this work Trombe walls were studied for summer cooling of buildings. Ventilation rates resulting from natural cooling were predicted using the CFD (computational fluid dynamics) technique. The renoramlization group ( RNG) k-e turbulence model was used for the prediction of buoyant air flow and flow rate in enclosures with Trombe wall geometries.
Gives an overview of current developments into passive ventilation technologies within office buildings and their impact on current ventilation practices. Covers prevention of heat gains, modulation of heat gains, and heat dissipation.
