• Tier 1 and 2 levels encourage local communities to take further action to green their buildings and to reduce greenhouse gas emissions, improve energy efficiency and conserve natural resources. • City staff has evaluated and compared Pleasanton's existing green building requirements with CALGreen's basic measures, and its Tier 1 and Tier 2 optional provisions. Mrs. Rondash indicated that CALGreen will help the State to meet its goals of achieving 33 percent renewable energy by 2020 and will curb global warming by requiring the following • Reducing water consumption, • Diverting construction waste from landfills, • Requiring the installation of low pollutant- emitting materials, • Requiring separate water meters for nonresidential buildings' indoor and outdoor water use, • Requiring moisture- sensing irrigation systems for larger landscape projects, and • Requiring mandatory inspections of all energy systems for nonresidential buildings over 10,000 square feet. Mrs. Rondash stated that CALGreen provisions will be inspected and verified by the City Building Division staff. She noted that the City's current process relies on programs from outside agencies, with commercial and public buildings being handled with LEED requirements produced by the United States Green Building Council (USGBC) and residential projects by Build It Green guidelines. She then provided an example of the LEED scorecard /checklist. Mrs. Rondash stated that the current rating systems measure how environmentally friendly or green a project is based on a point system. She noted that CALGreen is not a point system; it includes mandatory measures and electives with Tier 1 and Tier 2. Mrs. Rondash stated that staff was charged with comparing the two systems, and in order to compare the point system to a non -point system, staff converted measures in CALGreen to the points listed in the City's current programs. She then presented a table which was established to indicate categories evaluated and the minimum points for the current system as well as minimum total points. Staff listed CALGreen basic measures in the first column, CALGreen basic measures plus Tier 1 requirements in the second column, and CALGreen basic measures plus Tier 2 in the third column. Staff then assigned points which were already being required to evaluate how the points for each measure compared to the City's current system. Mrs. Rondash explained that in the LEED scorecard for commercial and public buildings, there is no category minimum; just a total point minimum, which is currently 40 points. She noted that when basic measures are calculated, 15 points are achieved; however, in CALGreen basic measures plus Tier 1 measures, 46 points is achieved, which is equivalent to the City's current system. She then displayed an example of achieving the total minimum points but not all category minimums. EXCERPT: PLANNING COMMISSION MINUTES, September 29, 2010 Page 2 of 15
