Enabled Energy (EE) was engaged at five locations across California to assess the existing cooling system and implement mechanical upgrades to the legacy equipment to capture energy savings, increase reliability and capacity, and to extend equipment life at each facility.
The EE team worked with the client to define a project scope to accommodate the client’s payback requirements and current load conditions while maintaining adequate cooling performance of the mechanical equipment.
Enabled Energy’s Solution
Enabled Energy visited each location to define the custom scope of work to lower the PUE of the site with a cost-effective solution. The scope of works included installing VFDs, underfloor plenums containment, and various mechanical upgrades. EE partnered with a local subcontractor to provide an efficient, end of year installation at each location.
These projects reduced the energy demand by roughly 98 kW and yield an estimated annual energy savings of 861,021 kWh in total over the 5 sites. This equates to nearly $138,599 saved on annual energy expenses. The average project payback is 0.94 years for the program.
