2. Approval of Minutes
3. LAH Green Building ordinance:
Jim Blomquist provided the perspective of a HERS rater on green building and energy
efficiency measures that can be implemented during construction and remodels.
• ACCA J,D,S – potential for 15-60% energy and dollar savings due to common
oversizing of components; cost of calcs may be similar to T24 building modeling
for a contractor with the software and experience. There may be an issue with city
plan review expertise. Jim claims $8,300/ year gas + electric spend on HVAC.
• Duct inspection – 40% leakage or more is common; 6% is the spec for new ducts.
So a 30% leakage rate reduced to 15% on inspection and repair is reasonable for
existing ducting. As-built duct performance is HERS verifiable; QII insulation
and duct work that will be inspected may be twice as expensive. Post-construction
duct inspections are already required in other CA climate zones.
• T24 compliance in remodels – Most remodel T24 calcs are done using an
“existing plus” model, so there is some consideration of the existing building.
• B.I.G – other municipalities (Santa Cruz) have their own Build-it-Green
checklists, and impose different requirements for post-construction checking.
The committee noted that the climate in LAH is more mild, and some of the high ROI
commonly attributed to HVAC efficiency improvements may not be realized here.
The committee also discussed the state of confusion in emerging green building
standards including LEED vs. Build-it-Green vs. CalGreen.
4. BACC Steering Committee report
NOTICE TO PUBLIC
Any writings or documents provided to a majority of the Environmental Initiatives Committee regarding any
item on this agenda will be made available for public inspection in the City Clerk’s office located at Town
Hall, 26379 Fremont Road, Los Altos Hills, California during normal business hours.
Raj Reddy attended the June 23 BACC steering committee meeting. Tracy George
reported that green jobs are growing more rapidly than the economy in general (mainly
due to solar) while energy consumption is falling. Steering Committee topics of interest
are solar energy, green buildings and EVs. People are interested in increasing EV’s and
PHEV’s in municipal and corporate fleets, consistent green building standards including
T24 + 20% performance and HERS II for existing homes and expanding energy audit
requirements.
5. Proposition 23 (AB32 suspension)
6. Acterra/High Energy Homes assessment program/partnership update
7. EIC meeting date change
The committee agreed to move its regular meeting date to the 4th Thursday of the month.
