The home also utilizes water efficient products and landscaping, design for optimum indoor air quality, and reused and recycled products.

This home demonstrates a variety of resource efficient features and strategies that can be easily replicated in other projects. Jackie O'Neil has actively sought to show her home and share her experiences so that more zero energy and resource efficient homes will be developed in Philadelphia in the future.
