Improvement of the indoor thermal environment over pilotis of RC buildings

摘要

In winter, surface temperature of indoor floors that cover outdoor pilotis is often too low for persons to work for a long time. In this research we tried to improve indoor thermal environment in meeting rooms on bridges that connected northern and southern buildings of Niigata Institute of Technology, Kashiwazaki, Niigata, JPN, by using floor carpets. We showed that thermal loss from floor surface to pilotis was greatly reduced because of large thermal resistance of carpets. And also we clarified that estimation of air temperature in closed spaces between ceiling panels over pilotis and floors of upper rooms was possible by using observed data of outdoor air temperature in pilotis.
