Globally Building Consumes upto 38% of total energy and emits 35% Carbon Dioxide.The Sector is growing at much faster rate and by year 2030,the consumption of electricity is expected to increase upto 50% globally.Taking Indian Scenario,the building sector consume total of 70% of electricity generated in entire country.Various research shows that more than 52% energy is required for resident comforts like heating,cooling(24*7).This trend in energy consumption will set to increase until there is enough effort to design energy efficient building and add renewables to compensate for increasing energy demand. The building Sector is now laying emphasis on Construction of Net Zero Energy building i.e. a building with Zero Net Energy Consumption.It can be explained that total amount of energy used in buildings on annual basis is equal to quantity of energy produced by site renewable. Also these buildings has lesser impact on green house gases and are climate friendly buildings. The design of Net Zero building focus on Operational Energy, leaving behind embodied environment impact over to life cycle of building. The building is evaluated for its energy efficiency by drawing relationship between embodied energy and operational energy. Careful Selection of building material and making appropriate placing technique of building element can reduce and optimize the EE(Embodied Energy) and OE(Operational Energy) of buildings. Also by choosing appropriate LCA (Life Cycle Assessment) technique has significant impact on EE.
