The research in this thesis aims to provide information about the uncertainty attached to the prediction of thermal comfort in buildings, in the context of the specific case of a naturally ventilated office building.

A new room model has been developed and validated in order to be used for the assessment of HVAC sensors, assuming non-homogeneous room conditions and distinguishing between different sensor positions. .

This CD gives information to understand and apply the new French Thermal Regulations RT 2000, which are applicable to new residential and commercial buildings and which mainly concern the calculation of energy consumption of buildings and comparison with reference values.
The CD includes the official texts of the regulations, a slide presentation of the regulations, software tools enabling the user to make sensitivity analysis of the calculation results to various parameters of the building.

Describes the testing methods of filters intended to be used in ventilation systems, and their classification according to their performance.

This article describes a new system developed and patented by a Belgian firm for air purification, using photocatalysis (UVA radiation + titania dioxide) for VOC and odour removal. Results from degradation tests are presented.

This report describes the actions which were operated since the end of 1999 for setting up the French Permanent Survey on Indoor Air Quality.

This paper reports some findings from IEA ECBCS Annex 35 about wind driven flow through building openings. Wind tunnel studies have been performed on simplified buildings, in order to know if pressure distributions on sealed buildings can be used to predict airflow through facade openings. A new parameter, the catchment area, is introduced by author.

A large opening has first been defined as "an opening where the flow is not fully unidirectional". Then an experimental setup has been installed to conduct wind tunnel measurements on several models of a circular disk, in order to characterize the pressure distribution on simple objects provided both with and without openings.

This paper intends to find a simplified method for the prediction of natural ventilation in a cross ventilated room . This method is based on the use of pressure boundaries instead of the modelling of a larger domain.

This paper reports experiments carried out in a scale model, about possibilities to use buoyancy forces to distribute air and heat through horizontal openings. Water and saline water have been used as operating fluids. This study focuses on the effect of a staircase on the fluid exchange through the horizontal opening. This research is planned to be carried on in a full scale 2 storey-building.
