You know the gas mileage of your car; you know the nutritional value of the foods you eat. But what about your home? OK, you can't drive it or eat it, but it does have performance, health, and sustainability metrics - if you know where to look. Like a nutritional label, our Sustainability Scorecard provides an easy reference for the ecological footprint of our homes.
The first section of our Sustainability Scorecard indicates how a home scores on the U.S. Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) for program Homes, the leading green building certification program. The second section explains the reduced impact of the operation of the home, and the third section explains the reduced impact of the construction of the home.
We also created a chart to help you understand the different ecological footprints of standard site-built homes, versus LEED Silver or Platinum homes. The greater the LEED score, the lower the negative impact – on your family’s health and the community in which you live.
