- Seal adequately: Make sure the new addition is thoroughly sealed to prevent air leaks and loss of energy. Caulk around doors and windows and their frames. Apply weatherstripping to block drafts. Ensure HVAC ductwork is tightly connected at all segments and that connections are sealed with mastic.
- Use natural lighting: Design the addition to take the best advantage of natural lighting possible. Include skylights, dormers, clerestory windows, and other sources of natural lighting. Control natural lighting with drapes and shades.
- Use energy-efficient appliances, HVAC equipment, and lighting: Where possible, replace older appliances and heating and cooling equipment with newer high-efficiency models. Replace old-style incandescent light bulbs with newer compact fluorescent or LED models that use less energy.
- Install sufficient insulation: Insulation in the walls, floors, and ceilings will prevent heat loss in the winter and the entry of heat in the summer. Make sure there is plenty of insulation in all portions of the new addition. Pay particular attention to attic spaces, which can be a significant source of energy loss.
