Space cooling has utilized lots of electricity in summers which has to be reduced by insulating inside of buildings. This has potential to reduce the environment pollution caused by higher expenditure of energy. The present work has the scope to evaluate thermal performance of a test model house providing cellulose fibre based cardboard insulation and compare the performance with an uninsulated model. The addition of heat through roof, walls and net heat gain during the day has remained lesser for insulated test model than uninsulated test model. The temperature of indoor air has stayed lesser in case of insulated test model than the uninsulated test model during the day particularly in the interval from 12 hrs to 19 hrs The indoor air temperature for the insulated test model has remained lesser by 7°C from 14 hrs till 16 hrs in comparison to uninsulated test model. The energy and financial savings obtainable for summers has value of 144 kWh and Rs 864 respectively for insulated test model. The carbon dioxide emitted has reduced for summers by 226 kg for insulated test model. Hence better thermal comfort conditions have existed in the insulated buildings.

Abstract


Space cooling has utilized lots of electricity in summers which has to be reduced by insulating inside of buildings. This has potential to reduce the environment pollution caused by higher expenditure of energy. The present work has the scope to evaluate thermal performance of a test model house providing cellulose fibre based cardboard insulation and compare the performance with an uninsulated model. The addition of heat through roof, walls and net heat gain during the day has remained lesser for insulated test model than uninsulated test model. The temperature of indoor air has stayed lesser in case of insulated test model than the uninsulated test model during the day particularly in the interval from 12 hrs to 19 hrs The indoor air temperature for the insulated test model has remained lesser by 7°C from 14 hrs till 16 hrs in comparison to uninsulated test model. The energy and financial savings obtainable for summers has value of 144 kWh and Rs 864 respectively for insulated test model. The carbon dioxide emitted has reduced for summers by 226 kg for insulated test model. Hence better thermal comfort conditions have existed in the insulated buildings.
