Old Buildings Get Smart Comfort Upgrade

Many older buildings, particularly in New York City, suffer from uncomfortable temperatures due to outdated heating systems. A new generation of horseshoe-shaped heat pumps, resembling window air conditioners but capable of both heating and cooling, are emerging as a solution. Gradient has introduced Nexus software, enabling these units to be networked within multifamily buildings.

This innovation is especially beneficial for aging structures needing HVAC modernization. Gradient has piloted its heat pumps in New York City public housing and an affordable housing complex in Tracy, California. The Nexus software allows building managers to set energy consumption limits, preventing overuse of heating or air conditioning.

One building manager reported a 25% reduction in energy consumption after implementing heating limits. Gradient's heat pumps are presented as a cost-effective alternative to replacing end-of-life boilers. Furthermore, they can provide air conditioning to units previously only equipped with steam radiators, offering a defense against increasingly severe heat waves.

Installation of these window units is rapid, often completed within hours, and avoids the need for electrical upgrades required by other systems. The Nexus software can even reduce power draw during peak grid demand, potentially preventing grid overload and lowering energy costs. Gradient aims to demonstrate that widespread electrification can coexist with grid stability.
