About this file

This document contains an energy audit template and details of a related federal contract opportunity. The template lists estimated energy and cost savings from potential energy conservation measures across various facility systems at a site, including boiler plant improvements, building automation systems, distributed generation, chilled water and steam distribution, and water conservation. The related federal contract opportunity is a pre-solicitation notice for boiler audits at multiple Department of Veterans Affairs medical centers under Veterans Integrated Service Network 4. The audits are to identify energy and cost savings from boiler plant optimization and upgrades. The notice indicates an official solicitation will immediately follow.
