TCAAP Energy Integration Resiliency Framework <br />Policy White Paper – Energy Efficiency Strategies (Demand-Side Management) <br /> <br /> 34 <br />greenfield, implementing energy efficient design practices on TCAAP would have substantial and long - <br />lasting impacts. By constructing buildings with higher performing envelopes, efficient mechanical <br />systems, and responsive technologies, some buildings can cost-effectively be built to consume as much <br />as 80% less energy than the average building or home. <br />A wide array of efficient design strategies could be applied on TCAAP, as is noted in the comprehensive <br />list in Exhibit III, but five high-impact approaches are highlighted in this section: <br /> Advanced building envelope design and heating systems <br /> Advanced and monitoring-based building commissioning <br /> Direct current utilization <br /> High-efficiency appliances and installation of smart plugs <br /> High-efficiency street illumination <br />Each of these strategies is seen as particularly relevant for TCAAP and could be implemented through <br />the development process, through city policy, or strategic partnerships. <br />6.4.1. Advanced Building Envelope Design and Alternative Heating Systems <br />In Minnesota, residential and commercial building and energy codes are set at the state level. While <br />enforced at the local level, cities and counties currently do not have the authority to adopt a more <br />stringent building code. While the City cannot adopt a more stringent energy code for TCAAP, the JDA <br />could urge developers to meet higher energy design standards through the request for proposal <br />process. The JDA may choose to elect a third-party set of energy or sustainability guidelines (e.g. SB <br />2030 or LEED) as a requirement or goal of buildings on the site, or they may choose to encourage a <br />select number of custom development guidelines. <br />The following subsections go into further detail about the design elements that will have the greatest <br />energy impact by building type. <br />6.4.1.1. Single-Family and Low-Density Homes <br />Starting in February 2015, Minnesota will begin enforcing the 2012 energy code (IECC). The updat es <br />will require homes to be more well-sealed and insulated,6 to have increased window efficiency, and <br />will require 75% of permanent lighting to be high efficiency. While these changes will result in more <br />efficient single-family houses and townhomes compared to current residential code, as part of the <br /> <br />6 International Energy Conservation Code 2012 <br />http://publicecodes.cyberregs.com/icod/iecc/2012/icod_iecc_2012_re4_sec003_par005.htm
