This whitepaper examines the growing use of on-site renewable energy production and energy storage and the impact these combined strategies can have on a building’s energy use profile. Co-authors Adam McMillen, IMEG Director of Sustainability, and Sean Smith, Chief Engineer for Trane Technologies, show how the right timing of production, storage, and use of on-site energy can enable facilities to eliminate their use of the electric grid during peak demand hours, save on energy cost, and reduce their carbon footprint.
