Rating of wall and roof sections—Thermal considerations
Abstract Several parameters are in vogue which provide the comparative thermal performance of wall and roof sections. They are either based on steady state heat conduction or do not respond to changing conditions of climate, design and usage. A criteria based on inside surface temperature and peak heat gain, for unconditioned and conditioned buildings respectively, of wall and roof sections has been suggested in this paper. The parameter known as thermal performance index (TPI) provides the relative thermal rating of several combinations of different layers of building materials of varying thickness and thermophysical properties. For the selection of a particular combination for summer period the lower the value of TPI better shall be the thermal performance. The data has also been classified depending on the range of TPI and class B has been found the most acceptable range both from thermal as well as economic point of view. The TPI values of prevalent combinations, single and multilayer, have been worked out for a representative climate. Some of data is presented in this paper. The data finds wide acceptability in field application and has been included in Indian Standard code of practice.
