Green Home Assessment Tool
(click on the tree icon)
This is a do-it-yourself home environmental rating tool for
existing homes. This tool is updated every month or so based upon user input. It is a work in progress and intended to provide you simple feedback as to how successful you are at being "green".
US Green Home strongly recommends your review of the LEED standards and checklist for a more complete assessment.
Consider professional testing to determine home air tightness and heater safety.
