GreenHouseTM Certified homes are designed to be approximately 20% more energy efficient than a minimum code-built house. Substantial energy savings are the result of using proven, advanced building assemblies, techniques and standards. What follows is a summary of many of the energy reduction strategies outlined in the GreenHouse Certification program.
Insulation - Increased insulation is a cornerstone of energy efficient design. Insulation levels are increased in exterior walls, attics, basement walls and foundations to minimize heat loss and, therefore, energy consumption.
High Efficiency Furnace - A state-of-the-art furnace burns less fuel more efficiently which reduces both heating costs and greenhouse gas emissions.
Windows – ENERGY STAR® qualified windows are big energy savers. When installed with proper flashing, the risk of moisture damage can be greatly reduced.
Air Barrier - A tight building envelope minimizes air-leakage through walls, ceilings and basements. A well-sealed home, properly ventilated with a Heat Recovery Ventilator, helps save energy for heating and cooling as well as increases comfort!
Heat Recovery Ventilators (HRV) - Controlled ventilation through air exchange systems removes the energy from outgoing (exhaust) air and transfers it to incoming fresh air, recovering 60-70% of energy that would otherwise be lost.
Electrical Savings - ENERGY STAR® qualified appliances, energy-efficient lighting and a host of other measures, reduce electricity consumption which, in turn, reduces the need to burn coal and helps reduce greenhouse gas emissions.
Hot Water - Hot water accounts for about 20% of a home’s energy use, so it’s a great place to look for savings. Incorporating an efficient hot water heater and a waste water heat recovery system can deliver real savings.
