Native plantings H. Geothermal heating and cooling system I. ENERGY STAR appliances and light fixtures J. Local stone K. Gray-water recovery L. Passive solar heating M. Rain-water collection

Why is adequate insulation important?

Approximately 50% of energy used in a home is for heating and cooling. Adequate insulation will help keep warm air in during the winter and keep cool air in during the summer

List three ways to reduce the amount of water used in a home.
