 Residential Home Design & The Affect On Energy Usage



This project was created due to a request for a research site for public school students studying house design and its affect on energy usage.  This area of the website is a compilation of data, facts, and information to be used by students in the elementary through high school grades to study how the design, location and positioning of a residential house structure affects energy requirements. 

Of course it can be used by anyone interested in learning how much you could save by simply positioning your house different ways...where to plant deciduous (lose their leaves) trees...or will a radiant barrier in your attic help you save on air conditioning costs.
