In a dedication ceremony, Hamann Construction, Innovative Cold Storage Enterprises Inc. (ICE), San Diego Gas & Electric (SDG&E), and SunPower Corp. have announced the completion of ICE II, ICE’s new solar-powered 134,511-square-foot cold storage building in San Diego, California. ICE expects to reduce its energy costs by more than 75 percent with the 1.1-megawatt, high-efficiency SunPower solar power system.

Storing four times as much product as the original plant, while using half the power, the “cool roof” solar system, designed to maximize insulation, is projected to generate 72 percent of the energy used by the facility, says ICE. The system also is expected to reduce carbon-dioxide emissions by almost 1.5 million pounds annually.

Financing for the solar power system was shared equally by Innovative Oil and Gas, a Hamann entity, and SDG&E, which will share renewable energy credits. The collaboration was part of SDG&E’s Sustainable Communities Program that sponsors green building, energy efficiency and renewable energy initiatives.

SDG&E awarded Hamann and ICE over $225,000 in incentive funding for the energy-efficient features and advanced technology designed into the building. These features include high-efficiency ammonia refrigeration, motion-detector-controlled LED lighting, ten 1-kilowatt wind turbines, rechargeable forklifts, narrow aisle racking and rainwater collection systems. The building is expected to attain gold certification from the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program.
