A heat recovery ventilator (HRV) is a balanced mechanical ventilation system that exhausts stale indoor air and supplies fresh outdoor air while transferring heat between the two streams through a heat exchanger core. An energy recovery ventilator (ERV) works the same way but also transfers moisture, which helps keep indoor...
A heat pump works in a building by moving heat instead of creating it. Using a refrigerant cycle driven by an electric compressor, it pulls thermal energy from the outside air, ground, or water and delivers it indoors for heating. In summer the cycle reverses, pushing indoor heat outside to...
Radiant floor heating is a system that warms a space by circulating heat through the floor itself, using either water-filled tubing (hydronic) or electric heating elements installed beneath the surface. Heat rises evenly across the room instead of blowing from vents, which keeps temperatures steady and removes the cold spots...
A building management system (BMS) is a computer-based control network that monitors and operates a building's mechanical and electrical equipment, including heating, ventilation, air conditioning, lighting, and energy meters. It links sensors, controllers, and software so operators can run these systems from one interface and keep performance steady. Most large...
Low-E glass vs standard glass comes down to how each handles heat. Low-emissivity glass carries a microscopic metallic coating that reflects infrared energy while letting daylight through, so a building stays warmer in winter and cooler in summer. Standard glass has no coating and allows far more heat to pass...
A structural insulated panel (SIP) is a load-bearing building component made of a rigid foam insulation core bonded between two structural skins, usually oriented strand board (OSB). According to the U.S. Department of Energy, SIPs replace studs, sheathing, and insulation in one factory-made panel for walls, floors, and roofs. For...
