DRAFT <br /> <br />Subd. 11. Environmental Sustainability Component. The PUD Master Plan shall <br />incorporate green building and design principles where feasible, and shall meet the <br />following requirements: <br /> <br />A. Building design. New buildings over fifteen thousand (15,000) square <br />feet in gross floor area shall incorporate at least two of the following <br />features: <br /> <br />1. Daylighting of building interiors, using window placement, <br />skylights, solar tubes, and similar techniques; use of energy <br />efficient, Dark Sky-compliant outdoor lighting for all outdoor <br />building and site lighting. <br /> <br />2. Meeting a green building performance standard such as LEED, <br />B3, or EnergyStar. <br /> <br />3. Incorporation of renewable energy features, including solar, wind <br />energy or geothermal systems, into the building or site. This may <br />include using the Army’s water treatment process to develop <br />geothermal energy generation capability and/or the use of land and <br />buildings for solar or wind energy generation. <br /> <br />4. Energy Efficiency: A minimum of a thirty-five (35%) percent <br />increase in overall building energy efficiency as compared to the <br />Minnesota Energy Code. Energy efficiency is to be defined by the <br />use of purchased (generated or refined at a separate site) or on-site- <br />generated fuels consumed per square foot of occupied space. <br />Calculations can take into account the use of the following: <br /> <br />a. On-site generated renewable energy, including photovoltaic, <br />wind, or hydro generation of electricity; passive solar systems using <br />solar heat or light; geothermal source; or other use of renewable <br />fuels displacing the use of non-renewable fuels in the building’s <br />systems. <br /> <br />b. Efficiency of all building mechanical systems that burn, convert, <br />or transform the energy in natural gas, electricity, oil, coal, steam, or <br />purchased heat or cold in any form. <br /> <br />c. Calculations shall not include manufacturing or mechanical <br />processes for which the State of Minnesota has not set a minimum <br />standard. <br /> <br />DRAFT: 6/3/2010 <br />Page 46 of 50
