A slice of history in downtown San Francisco – the Flood Building - is moving into the low-carbon future with energy retrofits recommended by Carbon Lighthouse.
The Flood Building has stood on Market Street since 1904. Surviving both the 1906 and 1989 earthquakes, the 12-story building is still in use, with over 350 commercial and retail tenants.
Energy solutions provider Carbon Lighthouse, along with the Flood Building’s property managing agent Wilson Meany, entered a partnership in late 2012 seeking to unlock the energy saving opportunities in the building.
The Flood Building is now more energy efficient than over 75 percent of similar commercial buildings. The building’s tenants will receive a fifteen percent reduction in utility costs, which translate to lifetime savings of about $4 per square foot.
“In addition to saving out tenant’s money on their utility bills, this project makes a significant dent in our carbon footprint,” said building owner Jim Flood.
The retrofit project has a lifespan of about twelve to fifteen years, during which time over one million dollars in energy costs will be saved and around 870 tons of carbon dioxide will be eliminated yearly.
Carbon Lighthouse uses a proprietary thermodynamics engine to locate hidden but substantial energy savings. The engine, dubbed as MOE, taps into twelve years of weather satellite data and highly granular building characteristic data to predict and model energy savings for ten year in the future.
Carbon Lighthouse and its clients then execute building improvements to achieve the energy savings seen by MOE.
In the case of the Flood Building, three types of improvements were put into place. These were the installation of a computerized central management system; improvements to the buildings H.V.A.C. system and lighting improvements.
These improvements were made while keeping in mind the preservation of the historical integrity of the building and with minimal disruption to the day to day business of the tenants which included the clothing boutiques Gap, Urban Outfitters and Anthropologie. – EcoSeed Staff
