Retro Fit and Refurbishment Projects

There are ways to retrofit existing HVAC systems to improve indoor air quality and save energy. High-impact retrofits include installing air economizers, heat and energy recovery ventilation, demand control ventilation, and building automation systems. There are other energy-efficiency upgrades that can help to reduce the cost of providing outdoor air for ventilation. 

Installing air economizers can help ventilate and cool a building in an energy-efficient way. Air economizers draw in outdoor air in order to meet the thermostat setpoint without using the air conditioner.
