To calculate head load, there are seven things you need to know:
1. Solar heat gain for floor, wall & Roof
2. Solar heat gain for glass & Window
3.Effective room sensible heat load
4.Effective room Latent Heat Load
5.Effective room total heat load
6. Effective room sensible heat factor
7. Dehumidified air flow

What is EPI ? What is the national bench mark of the EPI ?...
EPI Stands for energy performance index of commercial building.
It is one of the key metric used for benchmarking the energy usage of the commercial building.
EPI is nothing but the ratio of energy consumption and build up areas in a year. The unit of the EPI is Kwh/m2 /year.
The ideal bench mark of the EPI between 100 to 150 KWh/m2/year.
The national bench mark of the EPI is 180Kwh/m2/Year.
The EPI of the commercial building will change based on the five climatic zone of the India as specified in BEE.
