Query
Can we reuse Air Conditioners from another building in a GRIHA project?
Solution
Project team can reuse split ACs from another building.
Assumption for the EPI calculation or energy simulation :
The deterioration of efficiency has to be factored in. Project team has to EITHER consider lower EER factor / COP of AC (1 star lower from the rating at the time of installation, if it is not older than five years from the date of installation) OR provide third party testing/commissioning report for the AC and consider the same power consumption in EPI calculation.
Documentation:
1. Provide either the initial installation purchase order OR year of manufacturing.
2. Technical specification data sheet and model number.
3. Provide third party testing/commissioning report for the AC OR its star rating.
