ADDING-SOLAR-POWER-FOR-NET-ENERGY-ZERO-BUILDING.pdf

This paper deals with Building Energy Audit conducted at buildings located in a hilly region of West Bengal state and also provides the prospect of using solar energy to make all buildings achieve the status of Net Energy Zero Building. The study was conducted during the month of November-December 2017. This paper focuses on 13 identified buildings having roof of either flat or shed type which are shadow free and suitable to install roof top solar PV power plant. The total connected load, its type and roof area for each building is computed during the audit process. From the preliminary building energy audit data, the cost saving potential is calculated along with payback duration. As the buildings are in hilly region, we have also most hydro power plants (micro , mini and small) located similar to these regions thereby it can be implemented into all of hydro power stations across India. Solar power can be utilized through building integration or through floating solar PV plants in the reservoir (dam water storage areas) of hydro power stations.
