I have a question regarding using ResCheck to demonstrate compliance with EA 2.1 Pre-requisite Basic Insulation.

LEED permits using RESCHECK to establish 5% improvement to get credit EA 2.2 but there is no similar provision mentioned for establishing compliance with EA2.1.

Secondly, the IECC 2004 code allows you three approaches of establishing compliance. Can we use any of those approaches to meet this LEED Pre-requisite?

My first question is a derivative of the second.

Thanks in advance for your response.
