Residential Lighting Code Builder

residential lightning
Issue of Residential Artificial lighting accounts for a substantial portion of energy use in homes. Use of innovative lighting technologies can reduce lighting energy use in homes by 50 to 75 percent. Advances in lighting controls offer further energy savings by reducing the amount of time lights are on without serving a useful purpose and by turning lights on automatically as needed. Overview of Residential Lighting High efficiency lighting continues to be one of the most efficient way...

Residential HVAC

Issue of Residential HVAC Heating and cooling to maintain appropriate conditioning of indoor air consume a large portion of building energy use. Installing the right size equipment to heat and cool homes is essential to getting the best performance and comfort and reducing inefficiencies. A system that is too large will not keep the building comfortable because of frequent ‘on/off’ cycling. Incorrect sizing can also put stress on system components, shorten the equipment’s life, and lead to wa...

Commercial Fenestration

commercial building
Issue As the primary barriers between indoor and out, the openings of the building envelope, high performance windows, doors, and skylights (fenestration) are essential to an energy efficient building. Choosing such products involves several considerations, including appearance, energy performance, human factor issues, technical performance, and cost. Other factors like building orientation, natural and artificial shading, and climate will influence the properties selected for windows, doors,...

Air Sealing

air sealing
Issue Inadequately sealed building envelopes can lead to the movement of unconditioned air into and out of conditioned spaces. This process, known as air leakage, decreases the comfort of a building by allowing moisture, drafts, and undesired noise to enter. It applies to any holes, cracks, or gaps in the building envelope. It is important to control air movement in buildings because research indicates that air leakage can cause huge energy losses, accounting for up to a third of a home’s ene...

Residential Water Heating

water heating
Issue Circulating hot water systems distribute hot water to faucets on a “closed loop” system that circulates water to deliver it on demand. Heating water accounts for up to 25% percent of energy use in a typical home. High efficiency water heaters use 10% to 50% less energy than standard models. When combined with complementary products like insulation blankets and timers, advanced systems can save significantly on utility costs. Energy savings from high efficiency water heaters depend o...

Commercial Air Sealing

air sealing
Issue Inadequately sealed building envelopes can lead to significant air leakage that decreases the comfort of a building by allowing moisture, drafts, and undesired noise to enter. Air leakage may also reduce indoor air quality by permitting dust and airborne pollutants to infiltrate the building.   Overview A building envelope constructed with proper air sealing can provide many benefits, including: Increased comfort: A tighter building envelope reduces the amount of unco...

Water Heating

water heating
Issue In commercial buildings heating water can account for more than 25% of energy use. Depending on the type of commercial establishment the water heater is being installed in. A laundromat, hotel, or hospital may use large amounts of hot water where a office building may not. In any case, savings from high efficiency hot water heaters can be substantial. High efficiency water heaters use 10% to 50% less energy than standard models. When combined with complementary products like insulati...

Commercial Lighting

commercial light buildings
Issue Artificial lighting accounts for a substantial portion of energy use in homes and commercial buildings. Use of innovative lighting technologies can reduce lighting energy use in homes by 50 to 75 percent. Advances in lighting controls offer further energy savings by reducing the amount of time lights are on but not serving a useful purpose and by turning lights on automatically when and where they are needed. Overview High performance lighting with optional controls is a key element f...

Commercial Ventilation

Commercial Ventilation
Issue The air within businesses can become stale from moisture, odors, and pollutants that penetrate the building or are generated internally by human activity and out gassing from building materials and furnishings. A steady supply of fresh outdoor air can increase indoor air quality and improve occupant comfort. Commercial buildings have had consistent building codes requiring a specific amount of outdoor air to be ventilated in to the building. As envelope construction practice has improve...
