La Jolla, Calif., April 22nd – Optimum Energy LLC, a Seattle-based software company that develops and implements innovative technologies that sharply reduce HVAC energy consumption levels in high rises and other large commercial buildings, participated in the “Green” grand opening of the Aventine at La Jolla building on Earth Day 2008.

Glenborough LLC, a San Mateo, Calif., property-investment and management company recently finished the retrofitting and remodeling of one of their La Jolla, Calif. facilities. The software, from Seattle-based Optimum Energy, was installed in the Aventine at La Jolla office building and was commissioned December of 2007. The energy savings are expected to run about $110,000 a year, Glenborough says. This is a reduction from an average efficiency of 1.33kW/ton down to an average efficiency of 0.37kW/ton with Optimum Energy’s software controlling the buildings chiller plants. "We're looking at almost total payback in three years, which is very good considering how energy prices continue to rise." says Carlos Santamaria, Director of Engineering for Glenborough.

As an example, the period between March 1st and April 1st, Optimum Energy’s software operated the plant at an average kW/ton plant efficiency level of .37kW/ton. During this period, the average entering condenser water temperature from the cooling tower was 67.28 F. Savings for the month were calculated at 66,709 kWh or $10,006 for the month. The carbon footprint was reduced by over 81,650 lbs.

PlantPROCORE Calculating potential savings for the entire year, taking into consideration seasonal changes, the expected savings are as follows: $110,000/yr in energy savings, 756,000 kWh/yr savings, peak demand reduction at 67 kW and CO2 reduction of 937,000 lbs/yr.

“The Glenborough company really put on a first rate event for their tenants and it reinforces their commitment to “GREEN” buildings, said Optimum Energy’s Chris Roman. “They really are proud of their efforts to reduce Aventine’s environmental footprint and it is paying off huge dividends as they have earned the EPA Energy Star Rating and is registered with the US Green Building Council to attain LEED certification.”
