In the introduction of the paper are reasons presented, which cause local thermal discomfort. Currently the reasons of asymmetric thermal radiation are not clearly explained. Therefore I oriented my experimetal laboratory measurements, which were carried out in a special microclimatic laboratory on radiant ceiling heating. A special laboratory model of heating of interior was created. The measurements were performed with the help of a thermal mannequin that was used to measure the asymmetric radiation (that is asymmetry of perceived temperature).

A research project is designed to evaluate different aspects affecting human comfort in an architectural space. One of the basic parts of the research project is the evaluation of the auditory, visual and thermal comfort. A university library in Istanbul is selected as the subject of the research. The library building, which has unusual settlement and design peculiarities, is an interesting case from acoustical view point as well, because of the closeness to a heavy traffic road and architectural properties.

The construction of dwellings for people with low incomes in developing countries encompasses a broad range of issues starting from the choice of the building site, to the construction phase and finally to the evaluation of the building itself. For tropical climates, the thermal evaluation of low-cost dwellings should be primarily related to the optimization of internal comfort conditions. Usually low-cost housing projects are implemented throughout Brazil equally, with no concern to the climatic region where houses are to be built.

The indoor environmental quality of a building is intended as the thermal, visual, acoustic and indoor air quality performances as a whole, which provide health and comfort for occupants. In architecture, global approach to environmental quality design is necessary. High levels of quality are needed for each aspect, even though design requirements may at times be opposed. In order to determine opportunities and limits of global approach, problems related to visual and acoustic comfort assessment were examined for a baroque church in Italy.

The aim of this paper is to explain the results of a research project run in Yildiz Technical University which focuses on the optimum building envelope design for visual, thermal and acoustical comfort conditions in the offices placed in Istanbul city center. In this project, the building envelope alternatives are examined in terms of light, heat and sound considering the materials used mostly in Turkey.

The main goal of the present study was to determine thermal comfort parameters for dwellers of low-cost houses for a given set of indoor environmental conditions. 112 people living in over 60 dwellings were interviewed, according to a comfort questionnaire where information regarding age, sex, clothing, level of activity, thermal sensation and preference of the subjects was collected. Environmental factors such as air temperature and humidity were simultaneously registered with T/RH data-loggers. Results were then analyzed by comparing subjective and environmental factors.

This study investigates the behavior of vapor in a ventilated room in which vapor is being produced. A test chamber equipped with three types of ventilation ducts and a vessel filled with heated water for evaporation was analyzed both experimentally and numerically. Experimental results showed that temperature and moisture distributions differed depending on the ventilation types. A numerical model of vapor generation from the heated water was introduced to simulate the evaporation.

Based on the experimental results and predictions of a numerical model, the effects of uncertainty in estimation of imperfection of the interface on moisture transport were studied in the present study. It was found that, even though the imperfection of the interface varied with moisture content during the wetting process, the prediction using a constant resistance of the interface was close to that using an actual value.

This theoretical paper studies of the interaction between air curtains system and purging dilution systems in a real urban underground railway station in order to find the best design to reduce concentration of polluting gas toward adjoining environments. Numerical computations are carried out with NIST package Fire Dynamics Simulator (FDS). The use of an approximate form of the Navier-Stokes equations for low Mach number application is appropriate. Polluted gasses flow towards safe space can be reduced of the 26-53% by operating air curtain systems.

The main objective of our study was to know more about indoor air quality in offices building over a long period. Our study has been carried out in one building located downtown Lyon (France). Measurements have been carried out one day each month during a one year period. Indoor air quality in the offices along with the one of air flows of the HVAC (Heating, Ventilating and Air Conditioning) installation (outdoor air, blown air and returned air) has been characterised by temperature and relative humidity of air, dust concentration level, air biocontamination and CO2 concentrations.
