Encinitas City Hall
The City Council voted unanimously for Xnergy’s proposal to retro-fit the Civic Center and meet LEED certification. Scope:
- 100 kW Solar PV on roof. This provides “free” power during the most expensive time of the day.
- Addition of a “Cool Roof” over the existing.
- New 120-ton water-cooled central plant along with new 4-pipe air handlers.
- New TES (Ice Storage). Makes and stores the chill water at night when the electrical rates are half of what they are during the day.
- Natural lighting including Solatubes and skylights.
- Lighting Controls.
The Solar PV project for Southwest Traders included a 333 kW system mounted on the rooftop.
Equity Office Properties
Xnergy provided the EPC (Engineering, Procurement, & Construction) for over 6 MW of CHP (Combined Heat & Power) systems for the large real estate firm Equity Office Properties. The natural gas engines were used in combination with absorption chillers to offset utility electrical and gas usage for 10 class 'A' high-rise office buildings. These projects have saved millions of kilowatt-hours and dollars for the owners.
Abbott Vascular Site Expansion
The $25M contract for the Abbott Vascular expansion project required the conversion of an existing 122,000' sq facility to an ISO and cGMP compliant clean manufacturing space. The 1000-ton complex chiller central plant, ancillary equipment, and supporting offices and lobby space had to be fast-tracked. The design-build project from initial concept to completion took just 7 months and won the Associated Builders & Contractors Project of the Year.
Xnergy installed (4) 400kW hydrogen fuel cells at two separate Cox Communications facilities. The 1.6 MW of electricity offsets the dirty grid power from the utility. The fuel cells use natural gas as their fuel source, and then use an electrochemical process (no combustion) to efficiently produce very clean electricity and water.
This ground-mount 500kW solar PV project was included in Hawaiian Electric Company's (HECO) Feed-In Tariff program. The electricity produced is being sold to HECO and helping provide grid stability and clean energy for the island customers.
