This paper deals with the relevance of Computational Fluids Dynamics (CFD) results confronted tomeasurements carried out under uncontrolled thermal conditions. Experimental tests have been undertaken in a room and in a kitchen of an experimental house. Although the wall surface temperatures and the air intake temperature have not been imposed, the air change rates have been controlled during the measurements. Moreover, since measurements have been carried out in a real environment, air leakage has occurred at the walls.
New methods were used for that study, to evaluate the factors affecting productivity. Parameters of fatigue were investigated along with task performance.
There is research acknowledging that the home environment may be responsible for worsening respiratory conditions, especially for children. The indoor environment is a substantial source of exposure to pollutants e.g. environmental tobacco smoke. Apart from conducting specialised, costly and complex studies a method was needed to understand and assess indoor environments in the UK and how people could be encouraged to improve their indoor environment.
For historical and demographical reasons, in many European countries, an important part of educational building must be retrofitted. These retrofitting must be carried out in a context of reduction of greenhouse emissions and energy consumption.Among different targets for retrofitting, there are the improvement of indoor environment. In fact, educational buildings are particularly vulnerable to indoor environment problems. Studies have indicated a correlation between the way educational buildings are designed, or retrofitted, and student performance.
A heatlhy environment at work has become a real preoccupation. It began first in offices but now it exists in industry which was reluctant up to now in spending money for it, because the output responsibles were not convinced that such an investment could bring an output gain. A loss of productivity can depend on the ambiant temperature for example.
