Homebuilders and homebuyers across the country are increasingly interested in green building. But what exactly makes a home green?
Did you know that a typical home produces twice the pollution that a car produces during the year?
Green building means improving the way that homes and homebuilding sites use energy, water, and materials to reduce impacts on human health and the environment. Building a green home means making environmentally-preferable and sustainable decisions throughout the building process-decisions that will minimize the environmental impact of the home while it is being built and over the many years it will be lived in.
ENERGY STAR certified homes are independently verified to meet strict guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes save money on utility bills, provide a more comfortable living environment with better indoor air quality, and help protect the environment.
Typical features to look for in ENERGY STAR certified homes include:
Each ENERGY STAR certified home can keep 4,500 lbs of greenhouse gases out of our air each year. To put that in perspective, 4,500 lbs of greenhouse gases is enough to fill 275,000 one-gallon milk jugs. And because homes have such long life spans, this environmental benefit lasts for many, many years.
These energy efficiency improvements not only save money, they provide a house that is warm in the winter and cool in the summer. By providing comfortable homes efficiently, homeowners are operating their homes using less power, and less resources, a green choice that continues to give back after the construction has been completed.
Homebuyers can also look for the Indoor airPLUS label — a specification developed by EPA to address the indoor environment component of green building. Homes that achieve this level of excellence are first certified as ENERGY STAR, and then also incorporate more than 60 additional home design and construction features to control moisture, chemical exposure, radon, pests, ventilation, and filtration. Together, these features help protect certified homes and their residents from mold, chemicals, combustion gases, and other airborne pollutants.
EPA's WaterSense® program helps homebuyers purchase high efficiency products that save water without sacrificing performance or quality. The WaterSense® label makes it easy for homebuyers to find and purchase water efficient products and appliances that are backed by third party, independent testing and certification. Products with the WaterSense® label perform as well if not better than their traditional counterparts and are 20 percent more water efficient on average that other products.
Through the ENERGY STAR Certified Homes, Indoor airPLUS, and WaterSense® programs, homebuyers can address two critical green home elements. Then, look to the wide variety of available green home programs to complete the picture with water-efficient products, renewable energy technologies, waste reduction, recycling, and sustainable land development practices.
