Engineering services for HVAC and process support systems, including a Natural Gas use reduction effort for a facility of 1.5 million square feet of manufacturing, warehouse, and office spaces. A heating system was replaced, and the connected steam load reduced. A steam system was converted from high to low pressure steam, utilizing the existing steam distribution systems, and converting industrial parts washers from high to low pressure steam. In addition, a new boiler plant has been installed and winterization energy management processes were developed to close up the building and to ensure summer ventilation equipment is shut down. This $3.0 M project was offset by a Department of Energy (ARRA) Grant for $1.3 M.
