Retro-Commissioning for Larger BuildingsOct 10, 2014
According to the U.S Department of Energy, retro-commissioning can produce energy savings of up to 20% — in some cases adding up to millions of dollars in savings annually. Which is one of the reasons that retro-commissioning is of greater value to larger buildings than smaller ones in terms of energy savings, billable hours and the expense of the retro-commissioning process.
When we say that retro-commissioning benefits larger buildings more than small buildings, we mean buildings 50,000 square feet or larger. The majority of retro-commissioning projects are in fact focused on buildings 50,000 square feet and above.
For building owners who are concerned about the cost of retro-commissioning, there is good news. Reports have indicated that retro-commissioning projects that cost an average of $0.30 per square feet yield 16% energy savings while generating a payback of only 1.1 years.
Retro-commissioning can greatly reduce operating costs, with savings being impacted by factors like location, type of building, and the scope of the project. A study conducted by Lawrence Berkeley National Laboratory found that businesses could save $0.11 to $0.72 per square foot by means of retro-commissioning.
Some of the best candidates for retro-commissioning are building types that naturally tend to meet or exceed the 50,000 square feet mark. Buildings like hospitals, libraries, multi-tenant buildings, data centers, and laboratories are all good candidates for retro-commissioning because these types of large facilities have large air changes, quality facility staff, and a complex amalgamation of components.
