Energy Consultants are experts in the field of energy analysis. They analyze heating, ventilation and air conditioning (HVAC) systems, as well as the physical structure of a building, looking for potential leaks and inefficiencies. These consultants explain possible energy-saving measures, including changes in control settings, modifications to lighting and new controls or equipments that would make the building more energy efficient. They also help estimate potential costs and energy savings that would accrue after changes are made.
The Chicago Green Bungalow program has modeled green rehab techniques that result in energy savings from $575 per year to $1,050 per year in standard Chicago housing stock.
