Energy Efficiency

Energy efficiency is using less energy to provide the same level of energy service. An example would be installing insulation to use less heating and cooling energy to achieve the same temperature. Another example would be installing skylights instead of incandescent lights to attain the same level of illumination. Efficient energy use is achieved primarily by means of a more efficient technology or process rather than by changes in individual behavior.

Each energy assessment from Pfister Energy includes an evaluation of each porton of your building envelope, including noninvasive infrared scanning. Utilizing information about the age, construction, structural integrity and condition of the building, Pfister Energy will propose appropriate energy-saving retrofit options.

Building Envelope Improvements

• Applying cool roof materials to reflect the sun's heat before it enters the interior of the building.
• Upgrading insulation to maintain the building’s interior temperature.
• Adding window film or solar awnings to reduce the amount of sunlight entering the building.
• Applying green roof materials (plants, waterproof membranes and growing medium) to help the roof absorb less heat.

HVAC Equipment Improvements

• Installing highly efficient chillers or rooftop units.
• Adding a highly efficient heat pumpscan, which can save almost half of your heating and cooling costs.
• Checking and repairing leaking duct work to avoid heating or cooling loss.
• Maintaining and repairing roof top units to avoid energy inefficiencies.

Indoor Lighting Improvements

• Installing daylighting units to reduce energy costs and supply the building with natural light.
• Replacing incandescent bulbs to CFL's to reduce energy costs.
• Installing light sensors in spaces that are often left unoccupied for periods of time.
