Effective and efficient ventilation is essential when improving energy performance and Indoor Air Quality (IAQ) of buildings. Reducing air permeability can considerably improve the energy performance of buildings; however, making the buildings more airtight may result in lower rates of natural...

As the twenty first Century approaches, more emphasis is given to energy conservation and passive systems in order to maintain a clean environment. New strategies showed the necessity of reviewing some design elements and their evaluation techniques. Architects should seek to increase their...

This study is based on the analysis of the data obtained through a yearlong thermal comfort survey in one of the even naturally ventilated buildings in Oxford. It is concerned with how much the use of available controls contributes to thermal comfort by modifying the indoor thermal environment....

A 2D unsteady computational fluid dynamics (CFD) model is employed to simulate buoyancy-driven turbulent ventilation in attics with different pitch values and ceiling insulation levels under summer conditions. The impacts of roof pitch and ceiling insulation on the cooling load of gable-roof...

The paper discusses the possibility of offering thermal comfort, without inducing mechanical energy cost, in new habitations, built in European style and situated in a hot and humid climate, by means of a construction element: the Roof Solar Collector (RSC), which is made by using concrete...
