Retrofit Existing Buildings offer a chance to improve the energy efficiency of commercial building assets for their long-term usefulness. Retrofitting commonly entails making changes to already-existing commercial buildings that could increase energy efficiency or lower energy demand. Moreover, retrofits are frequently utilized as an opportunity to install distributed generation in a building as well. Energy-efficiency upgrades can save operating expenses. Especially in older buildings, as well as aid in luring tenants and gaining a competitive advantage.

Furthermore, from the initial planning phases to post-retrofit monitoring, the Building Technologies Office’s services enable planners, designers, and owners to concentrate on energy-use goals. How to carry out an energy-efficient retrofit is described in the Advanced Energy Retrofit Guides. Therefore, through simulations, energy modeling software assists in determining the most effective strategies. Additionally, during a refit, the Technology Portal can be consulted to help with fact-based buying decisions. Below are some more government resources.
