TCAAP Energy Integration Resiliency Framework <br />Brief <br /> <br /> <br /> 10 <br /> The advantage of large scale deployment to optimize economies of scale. <br /> Focus on replicable designs and proven technologies to simplify developer implementation. <br /> Emphasis on building performance based standards, instead of only design conditions. <br /> Important strategic partnerships with Xcel Energy and the Center for Sustainable Building <br />Research at the University of Minnesota. <br />High-Efficiency Commercial Buildings <br />As development moves forward it is recommended that the County, the JDA, and development <br />consultants utilize building standards, technical resources, planning tactics, and proposal criteria to <br />attract and streamline energy efficient development. <br />Utilize SB 2030 <br />Minnesota’s Sustainable Buildings 2030 (SB 2030) is a performance <br />based building energy standard developed to incrementally move <br />new commercial building construction to net-zero energy by 2030. <br />On average, SB 2030 will require commercial buildings to be 35% to <br />45% more efficient than the new building code (IECC 2012). As <br />nearly 75% of the energy loads for TCAAP are estimated to be in <br />the retail, commercial, and flex areas of the development, energy <br />conservation measures for these areas will be paramount for <br />successful achievement of the Energy Vision. The key way to <br />incentivize use of SB 2030 is to give preference during the RFP review process to proposals that plan to <br />implement these standards. <br />Sub-metering <br />Commercial and multi-family building sub-metering is an important consideration because the <br />additional design cost is relatively low when considered up front, but has the potential to maintain <br />lower energy use since tenants directly see and pay for their energy use. <br />Sub-metering has been shown to save up to 21% in leased building spaces.1 The material, software, <br />and labor cost for each sub-meter ranges from $5,000 to $7,500. Several metering companies provide <br />sub-metering services by owning, operating, and maintaining the meters. Monthly fees are based on <br /> <br />1 “Tenant Occupants of Green Office Buildings: Driving the Market for Improving Existing Building Stock” McGraw-Hill Construction and <br />CBRE.
