Insulated Panel Systems
One of the best methods for building a highly energy efficient home is to use an insulated panel system. These may be structural (structural insulated panels are called SIP's) or non-structural. The latter are used to enclose timber frames. SIP's are used for non-timber framed additions in a hybrid home. The panels are constructed of foam insulation -- expanded polystyrene (EPS) or polyurethane -- sandwiched between two layers of 7/16-inch oriented strand board (OSB). The panels employ a tongue and groove connecting system that forms an interlocking, uninterrupted insulation barrier against heat loss, heat gain or air infiltration.
Energy Efficient Windows
The energy efficiency of the walls and roof are not the only R-values today's homeowners need to consider. Windows let in more than just light and scenic views. The wrong choice in windows and doors can negate much of the energy efficiency a well-informed homeowner has been able to gain through an effective insulation system. In addition to their respective insulating properties, any quality window or door greatly reduces the infiltration of outside noises.
Energy Recovery Ventilator
With the energy efficient timber frame, we recommend installation of an energy recovery ventilation system (ERV). An energy recovery ventilation system will improve the indoor quality of the air and keep the humidity in the home at a constant. In any climate, this is beneficial to help control indoor relative humidity. In the heating season, an ERV will preserve essential moisture in the home while keeping it below excessive levels.
During cooling season it minimizes the added moisture that the incoming airflow may contain. An energy recovery ventilator continuously exhausts stale, polluted indoor air and replaces it with fresh outdoor air. Energy from the indoor air (warm air in winter, cool air in summer) is extracted and transferred to the fresh incoming air so there is little energy loss.
The energy recovery ventilator system will be installed by your local heating and air conditioning contractor and be an integral part of your heat and air conditioning system. In heating climates, remember heating the air may dry it to below a desired humidity level, in which case added humidification may be needed. The use of an energy recovery ventilation system in your timber frame home will enhance the indoor air quality and humidity levels to the most comfortable zone for you and your family. |
