UPDATE: Zero Net Energy Workshop Scheduled at the CPUC - June 15, 2011

BOMA San Francisco Members:

UPDATE - May 24, 2011

The Public Utilities Commission will conduct a public workshop on June 15 to discuss California’s policy goals relative to achieving Zero Net Energy (ZNE) in all new commercial buildings by 2030. While there is still debate over the definition of ZNE, at a minimum this policy goal will require almost all of a building’s energy supply to come from on-site sources. In addition to cost concerns, there are also serious physical design constraints which must be addressed, as was shown by a recent technical report commissioned by BOMA California.

That report analysis showed that a very energy-efficient 15-story commercial building in Oakland would still need nine acres of solar panels to cover its annual energy needs under such a policy. If that building were to use every inch of rooftop space for solar, that energy system would only generate enough power to cover 4% of the needed power supply.

We support the state working towards the goal of ZNE, but caution against adopting “stretch goal” mandates that knowingly cannot be reached. We are working with the state to consider other strategies in addition to ZNE, such as carbon-neutral buildings and neighborhoods, and increasing the overall supply of renewable energy at the source.

The workshop is scheduled for June 15 in San Francisco. Click here to read the state ZNE Action Plan, designed to identify the key actions required to achieve plan milestones, secure leaders for the steps to achieve these actions, and track and report on progress against the plan.

Please click here to read the California Long Term Energy Efficiency Strategic Plan--the commercial section starts on page 35--regarding Zero Net Energy (ZNE) use by new and existing buildings in California, and when such an energy standard should go into effect.  The Strategic Plan provides the necessary background information on ZNE and articulates the California Public Utilities Commission's (CPUC) long-term energy efficiency goals for each economic sector and identifies specific strategies to assist in achieving those goals.

Our BOMA California staff is working on the ZNE issue with the CPUC but they need to hear from BOMA San Francisco members as to what they think of GOAL 1: all new developments to be zero net energy users by 2030; and GOAL 2: half of existing buildings must be retrofitted to be zero net energy users by 2030.

BOMA California is also seeking a better clarification on the California Energy Commission's definition of ZNE, because, as it now stands, it would mean onsite energy production. If we can broaden the definition to include off-site clean energy such as solar, wind, hydro, biomass, etc., it might become a lot more palatable and achievable for the BOMA San Francisco membership to accomplish.
