Renovation, retrofit, and refurbishment of existing buildings represent an opportunity to upgrade the energy performance of commercial building assets for their ongoing life. Often retrofit involves modifications to existing commercial buildings that may improve energy efficiency or decrease energy demand. In addition, retrofits are often used as opportune time to install distributed generation to a building. Energy-efficiency retrofits can reduce the operational costs, particularly in older buildings, as well as help to attract tenants and gain a market edge.
The Building Technologies Office provides resources that allow planners, designers, and owners to focus on energy-use goals from the first planning stages through post-retrofit monitoring. The Advanced Energy Retrofit Guides outline how to conduct an energy-efficient retrofit. Energy Modeling Software helps identify the most impactful measures through simulations. And the Technology Portal can be accessed to make fact-based procurement decisions during a retrofit. Additional government resources are provided below.
