Simulation study has been carried out to assess energy saving potential in air conditioned buildings with application of roof and wall insulation system for a period of one year in composite climate of India. Out of total eleven cases, the first case is untreated and conventional building and is considered as reference building. The other five cases are roof treated building with five different thermal insulations without wall insulation. The remaining five cases are roof treated with similar insulations as previous five cases along with wall treated with EPS insulation from inside of the room. The minimum cooling load was observed amongst eleven cases when roof treated with Elastospray and walls treated with EPS thermal insulation. The study reveals that appropriate insulation can reduce cooling load by 30% when both the roof and walls are treated.
