agreement similar to the current Power Purchase Agreements in place. The challenge is ROI after staff time and current market conditions are considered, as well as the availability of eligible metered energy. 4) Wind power: Considering the City has already offloaded most if not all of its peak energy use to solar (soon to be up to 50%), it may be as or more cost effective to elect wind source for some or all of the remaining facility energy needs. This would allow the City to quickly transition the rest of its energy source to renewables. While it would cost a little more per watt than what the City currently pays, it may have a long-term ROI comparable to the solar agreements without utilizing and stretching staff resources. According to the Director of Public Works, we need to also be thinking in relation to renewables what our strategy is in the long term. He points out that while the City can claim a certain percent renewable now at certain cost due to current agreements, in 15-20 years those agreements run out. We will be left with solar equipment we own, but it is uncertain what their production efficiency will be and/or replacement costs. We may need to think in a larger scope about creating a "Sustainability Utility" that considers these costs and establishes a long term funding source and financial plan that can manage finances over a longer term view. 9 CE-IT2S3: Adopt building codes & policies that promote energy efficiency in new and existing buildings. According to the Planning and Building department, the City should evaluate whether the newer code versions provide energy efficiency benefits for new construction, and then evaluate whether we want to adopt them. New codes are available every three years and are next available for review in Jan/Feb 2018. This will initiate a review process, which will inform any case to the Board of Appeals. The Planning Department indicates that guidelines favoring energy efficiency could be included in the new Planned Unit Development (PUD) Guidelines. • Guidelines favoring energy efficiency should be explored in the new Planned Unit Development (PUD) Guidelines as potential "waiver criteria". • Evaluate the adoption of updated building codes to the further advancement of energy efficiency in new buildings in early 2018. 10 CE-IT2S4: Aim to achieve 80% of all points within the Energy & Atmosphere section of the USGBC LEED for new City building construction. The new Recreation Center is on course to earn between 60-79 points (Gold Standard) under the Energy & Atmosphere section of the USGBC LEED rating system. Due to cost, however, the City will not seek formal certification. Interviews with the Planning Department revealed that the LEED system, while popular, may not be the ideal rating system, with suggestions that the Green • Consider adopting a policy recognizing a suitable standard incorporating energy and water conservation (i.e. LEED Gold, Green Globe) for new construction of municipal buildings.
