HVAC

HVAC (heating, ventilation, and air conditioning) systems consist of air conditioners, heat pumps, boilers, furnaces, rooftop units, and chillers, as well as associated air handlers, ductwork, and water and steam piping. Heating and cooling are the largest sources of energy consumption in the residential and commercial building sectors, accounting for roughly 40% in commercial buildings. Because of this, even small performance improvements can generate substantial cost savings.

LIGHTING

Lighting accounts for 20% of energy use in commercial buildings, and many businesses experience high energy bills because of outdated and inefficient lighting. Light emitting diode (LED) technology offers savings in both efficiency and durability. Installing efficient lighting is one of the lowest cost/fastest payoff energy efficiency improvements available today.

BUILDING ENVELOPE

A building’s envelope includes everything that separates a building’s interior from the exterior: external walls, insulation, windows, and roofing. Think of it like a building’s skin.  Advanced building envelope materials can reduce building energy use and costs by lowering heating and cooling loads, which account for roughly 40% of commercial buildings. Additionally, air-sealing systems and efficient windows oftentimes have payback periods of less than five years.
