Best Practices
Glazing
In cold and hot weather regions it is highly recommended that the thermal integrity of a building be maintained through the proper installation of a high efficiency low e glazing system. Solar control window films have proven to significantly reduce solar heatgain and provide air conditioning costs, thus , lowering overall energy costs.
 
Lighting

White LED (light emitting diodes) is one of the few technologies available today that will have a direct positive impact on the global environment through efficiency, lifetime, and safety.

LED lighting provides immediate savings in power consumption. As usage increases, benefits build and accelerate payback. With highest efficiency, no mercury, and very long life, LED lights have the lowest carbon foot print among all other lighting sources. Lowest Power Consumption Reduced Cooling Loads Easily Dimmable Maintenance Free.LED lighting is up to 20% more efficient than traditional fluorescent lighting. Lower heat energy also means reduced cooling load, saving more electricity. LED lighting products last 10 times more (up to 100,000 hours) than traditional fluorescent lights resulting in 500% more in cost savings over florescent lights.

 
Light Control Sensor
Photo sensor technology and controls are cost effective, easy to install and calibrate. Studies have shown when installed correctly they can save at least 35% of energy used for lighting.
 
Air Sealing
Air leakage, or infiltration occurs when outside air enter the building uncontrollably through cracks and openings. Properly sealing such cracks and openings can significantly reduce heating and cooling costs, improve building durability, and create healthier indoor environment.
 
Foam Insulation
Spray foam materials cost more than traditional fiberglass batt insulation. However, since foam insulation provides insulation and air barrier it will reduce air tightness detailing (such as caulking and sealing), and construction time.
 
Insulating Concrete Forms
ICF construction makes a building perform better than a conventional structure. The air tightness of the building envelope, the combination of the concrete’s thermal mass and expanded polystyrene’s R-value result in an outstanding insulating product.

It is estimated that ICF construction can reduce HVAC costs up to 40%.
 
Photovoltaic and Wind Systems

Photovoltaic and Wind systems produce energy from sun light and the wind, generating no air pollution or waste. Sunlight and wind are free and abundant energy source. PV systems allows harvesting sunlight and generate electricity for use as needed. Wind energy systems utilize wind speed instead.

They have both long life expectancies and require minimum maintenance. The benefits far outweigh initial costs of both systems.

All best practices listed below can be implemented with positive returns at all locations visited on this engagement.

 
Digital Thermostats
A savings of 10% on heating and cooling bills can be achieved by simply turning back 10 to 15 degrees for eight hours. This can be done without sacrificing comfort by simply installing abd automatic setback programmable thermostat.
 
Automatic Faucets
Automatic faucets are water control devices helping save 70% of water that otherwise swirls down the drain. Other benefits found they help prevent or mitigate scalding accidents from hot water flow coming out of the faucets.
 
Energy Efficient Hand Dryers
Most people associate hand dryers with poor performance, energy inefficient and frustrating results. As new technology evolves, the hand dryer industry has revolutionize their products by making available new green designs that are effective and economical, as well as energy efficient and environmentally friendly. Greenspec approved product use 80% less energy and can dry hands completely in 10 to 15 seconds. Hand dryers promote hygiene and can provide 95% cost savings over paper towels.
 
Tank Less Water Heaters
Demand water heaters heat water directly without the use of a storage tank avoiding the standby heat losses associated with storage tanks. Demand water heater deliver a constant supply of hot water. Typically demand water heater can be 24 to 34% more energy efficient than conventional storage tank water heaters.
 
Solar Water Heaters
Solar water heaters are really preheaters. They raise the temperature of water before it enters the standard water heating unit. That means the electric element normally used to raise water temperature consumes less fuel. Solar water heating has two main benefits. First it saves costs by reducing the amount of energy. Second, direct use of solar heat has a very low impact on the environment.
