Recently built cold storage facility gets LEED Gold

By Randyl Drummer | November 16, 2009 | CoStar Group

El Cajon, CA-based Hamann Construction earlier this year delivered its 134,946-square-foot build-to-suit cold storage facility for Innovative Cold Storage Enterprises, Inc., (ICE) in San Diego County's Otay Mesa. And now the marvel of renewable energy and conservation has won LEED Gold certification from the U.S. Green Building Council.

Called ICE II, the property located on 6.78 acres near State Route 905 at 7350 Britannia Court is used as a refrigerated warehousing and storage facility for pre-packaged food items which are stored at minus-10 degrees Fahrenheit. The facility has a clear height of 60 feet, can hold 29,000 pallets and has a storage capacity of 7.5 million cubic feet.

The facility includes a one-megawatt solar photovoltaic roof developed jointly by Hamann and San Diego Gas & Electric. One 504 kilowatt Hamann-owned system will produce about 883,008 kilowatt-hours per year, directly providing about 36% of the facility’s energy requirements. The other 504 kilowatt system, owned by SDG&E, will provide locally generated power to the community.

The freezer interior has extremely narrow aisle racking to maximize the use of space. Additionally, the facility uses radio frequency technology and energy efficient electric forklifts. Other energy efficient features include day-lighting and high-efficiency lighting, a cool roof, increased ventilation, carbon dioxide monitors, reflective concrete and water re-use and conservation. The facility also includes about 5,000 square feet of office space.

The facility took four years to design and 14 months to build, said Gregg Hamann, vice president and CFO of Hamann Companies.

"We not only value green building from an environmental standpoint, we value it from an economical one as well," Hamann said. "Much consideration and evaluation was conducted on all possible energy-efficient measures, and we worked closely with expert subcontractors."

The ICE facility is 62% more energy efficient than a standard cold storage facility, and the energy efficiency features alone will save more than 3.4 million kilowatt-hours annually at an annual estimated savings of more than $408,000 at today's energy prices.

Between the entire solar roof system and the 10, one-kilowatt wind turbines mounted on the parapet, 73% of the facility’s energy will be provided through renewable energy sources.
