Commissioner Blank inquired if a 3,500-4,000 square foot home would change any of the calculations. Mrs. Rondash replied that this number relates to standard construction measures and applying green measures. She noted that the City’s current Green Building Ordinance would apply to a 3,500-square-foot home in the same way as CALGreen would apply to a 3,500-square-foot home.She added that the City would not anticipate any price change for construction. Mr. Corbett noted that the question of cost came up at the Chamber of Commerce’s first meeting with stakeholders, and this was the initial information from the CBIA. He added that staff then reviewed a study done by a consultant in Alameda County who looked at different types of projects, specifically 3,500- and 4,500-square-foot homes in the City’s climate zone, and the numbers for the 2,500-square-foot home were fairly comparable. He indicated that in both commercial and residential structures, the larger the structure the greater the cost reduction and payback time. Chair Olson noted that the staff report did not reference a 3,500- to 4,500-square-foot increase. He stated that he took the expensive side of those ranges, added it up, divided it by 2,100 square feet, and he arrived at a cost per square foot increase of $3.17. He inquired how staff arrived at $1.67 to $2.14 per square-foot increase. Mr. Corbett replied that the figures were provided by CBIA to staff in mid-August. He noted that CBIA, along with the AIA and other organizations, has been involved in the development of the code from the start. He indicated that CBIA is a stakeholder in developing the code and that they represent the builders and are supportive of cities going to the Tier 1 measures. Mr. Corbett added that costs would rise dramatically as one chooses the high end of construction materials. He used as an example the range of costs for toilets, depending on the type. Commissioner O’Connor inquired if having two different water meters for domestic use and for exterior use is an option or a requirement. Mrs. Rondash replied that it is a requirement listed in the CALGreen Code. She added that staff would be amending it to indicate that separate water meters would be required for indoor water and for outdoor water to meet the Tier 1 standard. Ms. Stern clarified that this is an amendment staff is suggesting. Mr. Corbett noted that having separate meters is a non-residential requirement and not a residential requirement. He added that it is currently a common practice and mandated for non-residential projects with over 5,000 square feet of landscape area, breaking it down to a smaller threshold or to 1,000 square feet of landscaped area.
