A: It’s easier on the earth, it can lower energy costs, and it provides a healthier home in which to live. According to the Sustainable Building Industry Council (SBIC), housing alone consumes 20% of America’s energy. Homeowners who choose to remodel green can lower their energy consumption by 30-50%. It’s widely agreed that forests produce 40% of Earth's oxygen, and that building supplies use 25% of its forests. Remodeling green by incorporating recycled materials or sustainable species will help homeowners to tread more lightly on Earth’s natural resources. More than 15 million Americans are estimated to have asthma, and more than 28 million Americans suffer from hay fever and other allergies, all of which are aggravated by poor indoor air quality, which can be improved by remodeling green.
