The SunKit shows you how to build using cost-efficient solar strategies in tune with your general climate and then tweaked for the local mico-climate. Two of the six options, sun tempered houses and sunroom additions, work well in almost any climate. Sun tempered houses often cost no more to build than a standard house but can save as much as 30% on heating and cooling.

When your site conditions allow, the Sunkit shows you how to adjust your house to add even more windows and greater thermal mass - things such as double drywall, radiant floor slabs and passive solar options.
