Investigation The Effect Of Bio Phase Change Material On The Thermal Comfort Of Building

Abstract

Office room building envelope gets warmed in summer session due to rise in temperature and reached around almost 40⁰C to 45⁰C which causes overheating of buildings, as a result, thermal discomfort increase and cooling energy demand increases in building especially in Sindh. Also, internationally energy demand rises in building sector, nearby 60% of the total energy used for cooling and heating purpose, Also on other hand unit price of electricity rise day by day in Pakistan. Therefore there is a need to adopt some techniques which minimize these adverse effects, one of them is discussed in this research work which is the passive cooling technique. Therefore this research work will focus on Bio Phase Change Material and their effect on the thermal comfort of the building. Hence, the PCM method can be an effective technique for designing of energy-efficient buildings for this region of the country (Hyderabad, Pakistan) . Thus, the purpose of current investigation is to check the effectiveness of the apply a selective passive cooling strategy to an office building model located in Hyderabad for better thermal performance and to decrease energy use of  building envelope in warm climate
