DOE Total Funding: $500,000
Cost Share: $63,750
Project Term: 2016-2017
Funding Type: Building Energy Efficiency Frontiers and Innovations Technologies (BENEFIT) – 2016 (DE-FOA-0001383)

Project Objective

Oak Ridge National Laboratory, in partnership with Georgia Tech and IntelliChoice Energy, will integrate its Ground-Level Integrated Diverse Energy Storage (GLIDES) system with HVAC systems to provide efficient building-integrated electrical and thermal energy storage. This system is capable of integrating and using low-grade heat, and reducing the energy requirements of the AC systems. This system enables smarter building-grid integration, as well as the use of low-grade heat, which would otherwise be lost in traditional HVAC systems.

Project Impact

HVAC accounts for 35% of the energy consumed by end use in both residential and commercial buildings, as of 2014, providing a great opportunity for improved energy efficiency1. This integration of GLIDES into HVAC systems has the potential to reach an energy storage roundtrip efficiency of more than 70%, while enhancing the HVAC coefficient of performance (COP) by 35%. The estimated energy savings of this technology is 1.3 quads annually. This efficient system will play a key role in achieving high levels of renewable energy penetration and in increasing electrical grid resilience.
