Effects of temperature and humidification in the office environment

In this paper, the links between temperature and Sick Building Syndrome symptoms on the one hand and temperature and workers'perceptions of air dryness in environments with and without humidification on the other hand are evaluated .The average intensity of symptoms and perceptions of dry air relative to room temperature in humidified and non-humidified conditions are studied. The results are presented then analysed .

Evaluating comfort with varying temperatures : a graphic design tool

A graphic tool is presented in this paper. The daily swings of temperature can be represented on this graph, and this point can be compared with the comfort zones for different activity levels. The graph allows the representation of climatic variables, the definition of comfort zones, the selection of bioclimatic design resources.

Material properties, room-climate measurements and building history - an interdisciplinary project to set the conditions of restoration and re-use for the fortress of Kufstein, Tyrol, Austria

For the restoration of the historic fortress of Kufstein, the high humidity problems encountered have required special investigations : the capillary water up-take characteristics of the wall stones and identification of the ventilation deficiencies have been studied.
Results show that a controlled ventilation system may help to reduce the problems associated with humidity and condensation.

Adaptive comfort temperature model of air-conditioned building in Hong Kong

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.

The dynamics of comfort and behaviour in buildings

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.

To be or not to be comfortable : basis and prediction

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.

Indoor air humidification, sick building syndrome symptoms, and perceived indoor air quality in the office environment

Dryness is still one of the major complaints concerning indoor air quality in office buildings and respective nonindustrial environments. Dampness in buildings in terms of excess amounts of water in the solid parts, and the harmful consequences have been discussed vigorously in recent years. Indoor air humidity, which means water vapour in the indoor air, has been given less attention.

Predicting indoor temperatures in closed buildings with high thermal mass

Temperatures in buildings with low and high thermal mass levels have been monitored during the warm period in Kenya. The effect of thermal mass in lowering the maximum indoor daytime temperatures has been evaluated as very effective.

Prediction of indoor gaseous pollutant dispersion by nesting sub-zones within a multizone model

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.

Development of PCM air filter and its application to a constant temperature air supply system

DEVELOPMENT OF A PCM AIR FILTER AND ITS APPLICATION TO A CONSTANT The authors have developed a PCM air filter which stabilizes the temperature of air passing though it. This PCM filter has great potential for applications that require a constant temperature air supply. In addition, it can simplify temperature control systems and can contribute to energy conservation. The material in the filter consists of sponge fibers coated with paraffin followed by a coating of resin to prevent leakage and vaporization of the paraffin.
