• <br />• <br />Proper Application and Detailing. Materials must be properly applied and correctly detailed, <br />especially at the base of buildings, along cornices, eaves, parapets or ridge tops, and around <br />entries and windows. Material changes must not occur at external corners, but may occur at <br />"reverse" or interior corners or as a "return" at least four feet from external corners. <br />Proper Application and Detailing. Material changes shall occur at <br />interior or reverse corners (a), or as a "return" of at least four feet from exterior corners (b). Material <br />changes shall not occur at external corners (c). <br />Prohibited Preferred <br />Consistent Application on Facades. All sides of buildings that face streets, parks, or other pedestrian - <br />oriented areas shall have the same level of architectural detail and fenestration (windows.) Entries at <br />corners should address both sides. <br />Energy Conservation and Climatic Response <br />The effects of the Minnesota climate can be mitigated through intelligent building design, <br />configuration, and landscape treatments. The following approach will also foster a regional <br />"sense of place." <br />Daylighting. Daylighting techniques minimize the need for electric lighting and can reduce peak - <br />hour energy consumption by as much as 20 percent. While windows are the most common form <br />of daylighting, light from windows rarely penetrates more than about 20 feet. Additional <br />daylighting can be obtained with clerestories, lightshelves, and skylights. <br />Ventilation and Thermal Mass. To lessen dependence on air conditioning, natural cross <br />ventilation should be maximized. Operable windows, transoms, doors, and vents are preferred <br />to facilitate airflow across a space. These openings are especially useful on sides facing toward <br />and opposite prevailing winds. <br />Passive Heating and Cooling. Site and building design shall consider passive heating and cooling <br />strategies such as deciduous tree plantings that provide shade in the summer and sun in the <br />DRAFT — 2/6/04 26 PAGINATION TO BE ADJUSTED <br />
