Indoor environmental quality in the residential sector significantly influences the occupants? wellbeing, having consequences on health and productivity. Integration of strategies of solar energy use, in passive system in the building architecture, is intended to reduce not only the energy consumption for heating, from non-renewable sources, but also to provide a healthy and comfortable environment for occupants. This paper presents the results of a study that aimed to assess the quality of the indoor environment ...

Industrial ventilation is an extremely complex area and involving deep knowledge of fluid dynamics in the modern version (CFD), three-dimensional propagation of heat, complex flow of fluids, steady state in transient conditions, operating problems, contaminants inside the industrial objective, and outside respectively. Ventilation and air-conditioning installations in industrial conditions are designed to ensure the purity of the air and the corresponding inside environment for man's activity and the nature of the...

The continuous improvement of building insulation and air tightness means that controlled ventilation is becoming more important every day. The ground-air heat exchanger makes a considerable contribution to this, especially when used in conjunction with an air heat exchanger unit. As well as increasing the quality of life within the building, this also provides significant energy cost reductions by using the embodied ground energy to pre-condition the incoming ventilation air. The Canadian wells use geothermal ene...
