HI All.

I have posted to my web site a program that I'm working on at the moment. In New Zealand a part of our Building Code H1, requires us to do some calculations on Domestic building with regards to energy efficancy and Insulation. One of the Requirements is for us to calculate the exterior wall area and the ratio of that to openings. This is what this video shows.

My question here is. Is there any requirements world wide that require a similar process? If so how are you dealing with it at the moment? Before I get to far into finishing this of maybe there is a chance to include other countries requirements.

Your comments will be welcome.

Cheers
