(#8197) Building Envelope Peak Heat Gain Factor and EPI threshold for cold climate in GRIHA v2015


The proposed project is located in Guwahati and will be registered under GRIHA v2015. The city comes under cold climate as per ECBC 2007 - Climate zone classification. When we come across Criterion:8 - Energy efficiency, there is no specific Building Envelope Peak Heat Gain Factor (W/sqm) and recommended EPI value mentioned in GRIHA v2015 for the cold climate category.

In this case, how can we proceed further? Kindly guide us on this.


Please refer to the tables below for Peak heat gain through building envelope thresholds and  EPI thresholds for Cold climate for different building typologies.
