This paper gives the description of a four-factor simulation design and a statistical procedure for analyzing material VOC time sensitivities with regard to the following parameter variations : VOC diffusion coefficient, VOC partition coefficient, material thickness, surface air velocity, along with their interaction effects.

This paper deals with the results of a large-scale survey performed to develop new notions about ACT (adaptive comfort temperature) in buildings in humid sub-tropical Hong-Kong ; the aim was to determine the adaptive interface relationship between indoor comfort temperature and outdoor air temperature in order to preset the indoor air temperature as a function of the oudoor air temperature.

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.

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.

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).

MARSIAN (Modular Autonomous Recorder System for the measurement of Autonomic Nervous System activity) is an ambulatroy measurement and monitoring portable system designed for the evaluation of emotional and sensorial reactions, especially in case of thermal comfort and discomfort.
Smart textiles integrate sensors, and communication system. Its own fibers have an active role of sensing or communication, in addition with its natural mechanical role.
There are 2 kinds of smart clothes :

Through the body is thermally neutral, it does not mean that there is a constant or equal thermo-equilibrium all over the body. There is a problem about the definition of the term "comfort" and the relationship between the thermal sensation and the affective estimate.

The human body is a thermal machine, immersed in air. In this paper, the thermoregulation of the body is presented and explained. Due to its thermoregulation, the body ensures its independent activity, regardless the outer temperatures. That system is quite complex, performant and reactive with a great adaptabitily.
To be valid and efficient, the modelisation of that system has to integrate all those exceptionnal characteristics.
