Mandatory Energy Audits in San Francisco
Could Increase Use of Energy-Efficient Glass

Owners of San Francisco's commercial buildings will have to send
an annual energy benchmark summary, per the city's Existing Commercial
Buildings Energy Performance Ordinance. Adopted in 2011, the ordinance
is being phased-in over three years for existing nonresidential
buildings 10,000 square feet and larger.
"This is going to help owners of existing facilities in San
Francisco become more educated about their own costs for energy
and opportunities to reduce expenditures associated with it,"
says Stewart P. Jeske, president of JEI Structural Glazing Systems
Engineering of Kansas City. "This will drive retrofit and renovation
efforts to reduce those costs and by that help the glass and glazing
industry in the San Francisco region. As owners become educated
about options to reduce those energy costs, there will be a natural
investment toward upgrading to energy efficient glazing systems."
Each whole nonresidential building larger than 10,000 square feet
must be benchmarked using the Energy
Star Portfolio Manager (ESPM). An annual energy benchmark summary
includes: contact information and gross square footage; energy use
intensity (how much energy the building used per square foot for
the year); 1-100 performance rating provided by the ESPM, where
applicable; greenhouse gas emissions from energy usage and; assessor's
parcel number (APN or block/lot).
"We're hoping that the new ordinance motivates building owners
to take advantage of the advances in fire-rated glass that we and
other manufacturers have made," says Jeff Griffiths, director
of business development at Safti First in San Francisco. "California,
especially San Francisco in particular, has always been a leader
when it comes to environmental stewardship and the preservation
of natural resources. Unfortunately, many design and building professionals
believe that the Leadership in Energy and Environmental Design certification
label doesn't necessarily assure long-term energy efficiency for
newly constructed buildings, and may be too costly for renovation
projects. Periodic audits of a building's energy performance based
on actual daily use seem to be a far more practical means of guiding
and monitoring energy efficiency."
