• <br />• <br />winter. Heat-retaining thermal mass (such as concrete or brick) designed into building walls or <br />columns absorbs heat during the day and radiates heat at night. <br />Building design that shades openings reduces direct heat gain during the day. Shading elements <br />can also add dimensionality to building facades. Eaves or awnings can be sized to shade <br />windows in the summer but admit sun in the winter when the sun is lower in the sky. <br />Pedestrian Shelter. Building exteriors shall provide pedestrians shelter from the sun, rain, and <br />snow. Awnings, entry porticos, arcades, and overhanging eaves are particularly appropriate at <br />pedestrian pathways. Garden structures such as trellises and arbors (with or without vines) shall <br />be used to shade pedestrian routes and seating areas. <br />Other Structures <br />Service Areas <br />Service areas are places where truck loading takes place, refuse is stored, or mechanical <br />equipment is mounted. Service areas must be located away from and screened from view of <br />streets, parks, and plazas, and landscaped walkways. <br />Appropriate screening strategies include vine- covered walls or fences, trellises, arcades, dense <br />landscaping reaching a height of 6 feet, or some combination thereof. Where service areas cannot <br />be avoided along a street, park or plaza, they must be recessed within a building's envelope. <br />Trash dumpsters shall be enclosed on four sides. On grade mechanical or electrical transformers <br />shall be screened from view. <br />Fences & Walls <br />Walls and fences within view of streets, parks, or plazas must be constructed out of attractive, <br />long - lasting materials, such as wood, wrought iron, masonry, or stone. Chain link and wire <br />fencing must not be used. Walls and fences must not exceed 42 inches in height within 20 feet of <br />streets, parks, and plazas. <br />DRAFT — 2/6/04 27 PAGINATION TO BE ADJUSTED <br />
