Most homes and commercial buildings were built before today’s zero energy materials and technology when fuel costs were reasonable. Home owners tried to compensate with advanced insulation, air sealing techniques and lowering thermostats to produce warmer homes and lower their energy bills.
But even today´s zero energy buildings waste energy. As energy efficient technologies and equipment are becoming less and less expensive, a zero energy building energy audit is the first step to improve homes energy efficiency.
A certified energy auditor should start with reviewing the cooling and heating appliances, hot water heaters, HVAC equipment, attic, wall and floor insulation, roof, doors and windows, lighting, kitchen and laundry appliances and inspect all the other aspects of your home or commercial building. Blower doors, infrared cameras, and heating system testing devices are used to conduct the building energy audit.
