Many indoor models have been developed to describe thermal indoor discomfort, but are they relevant to outdoor or semi-outdoor environments ? They have not been yet critically validated . So, the thermal comfort of more than one thousand subjects living in outdoor and semi-outdoor locations in subtropical Sydney has been investigated by a questionnaire on the one hand and measured with micro-meteorological instruments.

This paper describes a numerical model that takes into account the indoor air moisture and its transport by the airflow, within an enclosure. That model is a potential useful tool for correctly estimating the indoor environment in steady and homogeneous thermal conditions.

The nesting of a new zonal model within a multizone model has allowed an increased resolution in the prediction of local air flow velocities, temperature and concentration distributions between rooms and within rooms.

The objective of the European project AIRLESS was to develop strategies, principles and protocols to improve and control the performance of HVAC systems and their components to be incorporated in codes and guidelines.This paper is a sum-up fo the first-phase of the AIRLESS project : definition of air pollution caused by HVAC systems, investigation to prevent this pollution and definition of strategies to keep away that pollution.

This paper describes a new tool, ils architecture and its predictive performance. BACH is a computational tool for air flow simulation in and around buildings in the early stages of the design process.

An effective sensor for thermal comfort index is necessary for a successful comfort index-based HVAC control system. A comfort sensor with a new structure is proposed in this paper. This instrument consists of an equivalent temperature sensor, a relative humidity sensor and a temperature sensor.
Simulations show that the suggested PMV and SET sensor can have a good measurement of PMV, but for SET more research is needed.

Objective measurement, CFD modelling and subjective assessment have been used in that study to evaluate the thermal comfort of an air-conditoned lecture theatre in the tropics. The simulated parameters are temperature, airflow rate and relative humidity.The parameters were found in the limits of the comfort standard. Occupants' vote show that they were uncomfotable and dissatisfied.

The dispersion of contaminants in an office environment has been investigated. The first experiment was made in a full-scale typical office equipped with two workstations located in the middle of the room and separated by a low-level partition, and the second experiment took place in a room separated in two halves with a low level partition, with one workstation at each corner. A constant injection of tracer gas allowed the measurement of the concentration of contaminant in the chamber for both the layouts.

This paper deals with thermal comfort as part of the dynamic interaction between people and their environment. The comfort temperature is continuously changing. The author introduces the idea of an adaptive thermal comfort through an exploration of the results from thermal comfort surveys in that field. Implications of this approach for building is studied along with how existing technologies should be modified or extended to predict energy use and comfort in occupied buildings.

In the EDF comfort-laboratory, realistic environmental chambers have been designed, furnished and decorated like offices and flats. A large panel of representative consumers has been evaluated on their preferences in terms of comfort, in parallel a small panel of trained experts has carried out sensation measurements. Then a correlation between the data of both studies has been used to explain the preferences in terms of sensations (sensation mapping).
