Thanks for all descriptions and comments related to differences beween EAp1 and EAc3. I`m still confused about Exemplary Performance and it`s "comprehensive envelope commissioning". I will greatefull if someone could describe it (how to achieve extra EP point and what CxA should do) in some other words than it has been written in LEED manual.

For now I`m guessing that its about enhancing the exterior thermography and heat flow control.

Thanks
