Energy gain in a cold season using mat insulation in different material buildings

Jahangir Payamara

This paper describes how to measure conductivity of a new insulator. Mat is made up of Agave plans which are now produced in Iran; it can be used in walls of buildings to reduce energy loss in cold season. In this work the thermal conductivity for mat is to be 0.06949 J/s.m°c and also from temperature gradient curve it was found that the temperature changes uniformly with thickness of the mat. Finally the difference of the energy gain in the concrete buildings with & without the mat was estimated to be 12.285×10³ kcal and with and without in the brick chamber was calculated to be 1.956x10³ kcal in the cold season in Tehran.
