RENEWABLE RESOURCE CHECKLIST FOR BUILDINGS Encourage designs that shade the structure to avoid after-the-fact fixes like solar screens. Encourage design “buffers” on west walls (like garages and closets) to reduce the impact of afternoon summer sun. Sometimes this is as easy as flipping the elevation so the garage is on the west side. Minimize carpet area and make use of the thermal mass of tile and finished concrete floors. Install windows rated by the National Fenestration Rating Council and optimize the climate appropriate window to square footage ratio. Ensure that window placement allows flow-through ventilation, both from prevailing breezes, and by low and high windows that draw air through the house. Optimize insulation levels. Install or encourage high-efficiency appliances. Minimize electrical needs. Reduce hot water needs with water conservation
