The impacts of indoor thermal environment on body physiology have been carried on for four years (2003-2007) in laboratory in Chongqing, a typical city located in hot-summer and cold-winter region in China. Experimental objectives used are healthy university students. The range of indoor air temperature in summer is 25 C - 37.5 C.The objectives physiological changes (Motor nerve Conduction Velocity, Sensory nerve Conduction Velocity, Skin Temperature etc.) under different temperatures and ventilations have been tested.

Concerns about energy efficiency, has brought new constructive trends researches. Aspects as environmental comfort is quite important, with regard to new constructive technologies, showing the need of standardizing Brazilian buildings to acquire thermal comfort. The necessity of new internal environment data in buildings has motivated surveys about it. The proposal is to present the constructive typologies of buildings and their indoor variables in Curitiba city, Parana state, South of Brazil, relating it to the Bioclimatic Chart, proposed by Givoni [1], for countries in development.

Currently, numerical simulation research on indoor air and human thermal comfort usuallyfocuses on the air-conditioning room in summer. This paper uses an Air-conditioneddormitory in winter as a model to study indoor airflow and human thermal comfort. Thispaper uses k -e three-dimensional turbulence model and N-S equation, considers airflowwith room shape and obstacles as one, calculates the indoor airflow and heat transferproblems with overall solution, studies indoor air form especially velocity field withnumerical simulation.

Energy efficient behaviour was studied by a questionnaire addressing office workersaltogether in 34 office buildings in Finland, Sweden, the Netherlands, France and Italy. AFinnish occupancy study of the possibilities to adjust working environment and thus gainbetter working efficiency offered comparative reference results on similar themes.The possibility to control personal working environment was most important for the officeworkers. The qualitative building automation had a positive influence on the feedbackregarding workspaces.

This paper presents the findings of a short-term monitoring exercise and questionnaire surveyto assess the thermal comfort conditions actually being achieved in 6 Iranian Office buildings.The findings of the questionnaire and monitoring are compared to give confidence that thequestionnaire is accurately reflecting the calculated comfort conditions obtained from thephysically monitoring and site observations.

Subjective experiments were carried out in a climate chamber using 16 Japanese subjects ofboth genders, in order to evaluate human comfort at very low humidity. Two levels ofabsolute humidity were set, 2.0 g/kg(DA) and 10.0 g/kg(DA). Three air temperatureconditions with absolute humidity of 2.0g/kg(DA), 20.0C/13%RH, 25.0C/10%RH and30.0C/8%RH, and 3 conditions with 10.0g/kg(DA), 20.0C/68%RH, 25.0C/50%RH,30.0C/38%RH, were examined. People were exposed in a chamber for 90 minutes withsedentary activity.

Physiological parameters measured by an embedded body sensor system were demonstratedto respond to changes of the air temperature in an office environment. The thermal parameterswere monitored with the use of a wireless sensor system that made possible to turn anyexisting room into a field laboratory. Two human subjects were monitored over dailyactivities and at various steady-state thermal conditions when the air temperature of the roomwas altered from 22-23C to 25-28C. The subjects indicated their thermal feeling onquestionnaires.

This study investigated on a subject’s thermal sensation and use of a “Cool Chair” in two actual warm offices. We developed a chair-mounted isothermal airflow generator called the Cool Chair that adjusts the local thermal environment by changing airflow v

Thermal comfort studies and standards show that room temperatures should be higher in thewarmer season than in the colder season. An interview survey with a sample size of 3,094people was performed in Finland. The respondents were asked to state the Celsius values ofroom temperature they prefer in the winter and summer season in living room at home. Theresults show that people have a false idea of comfortable temperatures. 41% of therespondents think that room temperature should be lower in the summer season than in thewinter season.
