(#8495) HVAC and lighting load consideration for areas under tenant’s scope.


For Tenant occupied residential buildings, do we consider common area HVAC and lighting; or do we consider lighting and HVAC for areas under the tenant’s scope?


As per the GRIHA V 3.1 , in order to meet the mandatory requirement of Criterion 18, the rated capacity of the proposed renewable energy system should be equal to or more than 1% of the connected load of internal lighting (common area and tenant occupied spaces both), external lighting and HVAC consumption.
Note: In case if internal lighting is not provided at stage of assessment, then consider ECBC base case LPD to calculate internal lighting Energy load demand.
Additionally, the internal lighting energy offset shall be calculated on the basis of overall internal lighting consumption as determined by the energy simulation.
