Proper Application and Detailing. Materials must be properly applied and correctly detailed, especially at the base of buildings, along cornices, eaves, parapets or ridge tops, and around entries and windows. Material changes must not occur at external corners, but may occur at "reverse" or interior corners or as a "return" at least four feet from external corners. Proper Application and Detailing. Material changes shall occur at interior orr reverse corners (a), or as a "return" of at least four feet from exterior corners (b). Material changes shall not occur at external corners (c): � /Vy • • • •1• Prohibited Preferred Consistent Application on Facades. All sides of buildings that face streets, parks, or other pedestrian - oriented areas shall have the same level of architectural detail and fenestration (windows.) Entries at corners should address both sides.. Energy Conservation and Climatic Response The effects of the Minnesota climate can be mitigated through intelligent building design, configuration, and landscape treatments. The following approach will also foster a regional "sense of place." Daylighting. Daylighting techniques minimize the need for electric lighting and can peak- hour energy consumption by as much as 20 percent. While windows are the most common form of daylighting, light from windows rarely penetrates more than about 20 feet. Additional daylighting can be obtained with clerestories, lightshelves, and skylights. Ventilation and Thermal Mass. To lessen dependence on air conditioning, natural cross ventilation should be maximized. Operable windows, transoms, doors, and vents are preferred to facilitate airflow across a space. These openings are especially useful on sides facing toward and opposite prevailing winds. Passive Heating and Cooling. Site and building design shall consider passive heating and cooling strategies such as deciduous tree plantings that provide shade in the summer and sun in the winter. Heat - retaining thermal mass (such as concrete or brick) designed into building walls or columns absorbs heat during the day and radiates heat at night.
