This federal courthouse building, originally built in 1966 and renovated in 2004, required retrocommissioning services to perform a comprehensive energy and water evaluation to lower building energy consumption. Tenant comfort and building health issues were also important to the client.
Using ASHRAE commissioning guidelines, the detailed plan included HVAC, lighting, plumbing, and building envelope systems. The project consisted of site investigations and performance testing to identify potential improvements necessary for optimal building operation, including correcting building operational deficiencies. Final deliverables included a list of Environmental Control Measures (ECMs), with documentation supporting the viability of replacing building mechanical equipment. The final report included estimated payback and lifecycle cost information. The building remained in operational use during the entire process. The full scope of work for this study included the following:
While this LEED Silver® building was already running at a highly efficient level, retrocommissioning revealed energy savings equivalent to an estimated 10% reduction in total energy and domestic hot water costs.
