Guest Commentary: Water Loop Heat Pumps

| Designing net zero energy buildings for new construction and for renovation of existing buildings presents a diverse set of challenges. It requires analyzing the unique energy use of the entire building and then designing a system that can reduce the net energy footprint without sacrificing functionality or comfort. And as the net energy is reduced, onsite renewable energy plays a larger role in efforts to reach the net zero energy goal. The type of heating, ventilation, and air-conditioning (HVAC) system selected must offer fundamental characteristics. It must provide comfort by independently heating and cooling individual temperature zones, capture and transport waste energy throughout the building, be scalable for any size building, readily connect to and share energy with a wide range of other HVAC and non-HVAC systems within the building, and most importantly, easily connect to onsite renewable energy systems. While this may sound complex, a water source heat pump (WSHP) system can provide solutions. ... READ MORE
