Size:                 Larger home=more resources/more $ 

                        Smaller home=less resources/less $

Building Design:  takes advantage of natural light (less need for artificial lighting), shaded from direct sun

Green Building Materials:  non toxic building materials,  low- and zero-VOC (volatile organic compound) paints and sealants, use of salvaged and recycled material,  use of rapidly renewable resources such as bamboo and FSC (forest Stewardship Council) certified wood.

Windows & Doors:  seal their openings tightly to avoid heat gain in summer and heat loss in winter.

Energy Efficiency: A green home has energy-efficient lighting, heating, cooling and water-heating systems. Appliances should have ENERGY STAR® ratings.

Renewable Energy:  Ideally, the home should generate some of its own energy with technologies like photovoltaic systems or wind energy

Water Efficiency:  water-conserving irrigation system and water-efficient kitchen and bathroom fixtures, Rainwater collection and storage system.

Indoor Air Quality:  The HVAC (heating, ventilation and air conditioning) system should filter all incoming air and vent stale air outside.
