After a delay, the project team has identified a new site and developed an installation strategy. The team is currently identifying the most suitable equipment to meet the project requirements. Technologies include heat pumps that are powered by utility-provided fossil gas with the exhaust used to provide additional efficiency in heating. This technology will reduce onsite gas consumption, as there is insufficient electrical infrastructure at the site to electrify the building with other technologies.
This project will deploy emerging and replicable gas heat pump technology in an office building on the NBC Universal campus to demonstrate a reduction of gas consumption of at least 35% and to develop replicable approaches for other large commercial buildings. Gas heat pumps are a high-efficiency technology that can supplement or completely replace traditional boiler systems, which use substantial amounts of fossil gas for water and space heating. The technology uses an engine powered by fossil gas to compress refrigerant similar to existing heat pump technologies, but on a larger commercial scale and without a large electrical demand. The heat from the combustion gases is also used to further improve the heating efficiency. Once the quantifiable and measurable benefits are determined, the project team will distribute the information and raise awareness of this potentially innovative technology. Finally, the team will develop a plan to promote and maximize the benefits in an equitable manner for the local communities where this technology will be deployed.
Gas heat pumps are a high-efficiency technology that can be deployed to supplement or replace traditional boiler systems in commercial buildings. By capturing heat from ambient air, gas heat pumps have energy efficiency ratings (Coefficient of Performance) of 1.3 to 2.2. This is significantly higher than traditional boilers (approximate COP of 0.80-85). Gas heat pumps provide energy diversity to increase the resiliency of energy systems.
Reduction in fossil gas use directly results in operational cost savings. Gas heat pumps avoid high electrical peak demand charges for large commercial buildings that coincide with times when space and water heating is greatest.
