Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Prerequisite 1 Erosion & Sedimentation Control Intent Control erosion to reduce negative impacts on water and air quality. Design to a site sediment and erosion control plan that conforms to best management practices in the EPA’s Storm Water management for Construction Activities, EPA Document No. EPA-832-R-92-005, Chapter 3, OR local Erosion and Sedimentation Control standards and codes, whichever is more stringent. The plan shall meet the following objectives: - Prevent loss of soil during construction by storm water runoff and / or wind erosion, including protecting topsoil by stockpiling for reuse. - Prevent sedimentation of storm sewer or receiving streams and / or pollution with dust and particulate matter. Technologies & Strategies Adopt an erosion and sedimentation control plan for the project site during construction. Consider employing strategies such as temporary and permanent seeding, mulching, earth dikes, silt fencing, sediment traps, and sediment basins. SLC+ Recommended Strategies Provide stormwater, sediment and erosion control plan to City and to SLC+ certifier, and coordinate design reviews and construction process with appropriate agencies, offices and SLC+ certifier. Sites_v10.doc 2 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Prerequisite 2 Public Facilities Siting Site major cultural, entertainment, recreation/sports, governmental, health care and other intensive, publicuse facilities at locations that support Master Plan and long-term City visions of a sustainable future, under guidance of SLC Planning Department. SLC+ Intent Strengthen City functions and values through integrated, cooperative planning and site selection.. Sites_v10.doc 3 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Prerequisite 3 Site Characterization and Assessment (SLC+) Prepare a brief, written summary of site characteristics and relationships with neighborhood(s), transit and transportation systems, demographic and development history and trends, and City plans for encouraging qualities such as infill, walkability, and emergency access. Identify: important neighborhood or area public facilities, parks, recreation facilities; natural features such as waterways, wetlands, woods or undisturbed vegetation communities important wildlife populations (in addition to threatened & endangered species), such as migratory shorebirds and waterfowl, small mammals, and winter range for large ungulates. Sites_v10.doc 4 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 1 Site Selection Intent Avoid development of inappropriate sites and reduce the environmental impact from the location of a building on a site. SLC+ Enhanced Intent Encourage site selection in city center, neighborhood centers, or sites that contribute to urban compactness, thereby avoiding development of sensitive riparian, Lakeshore, playa and remnant wetlands habitats. Requirement Credit 1.0 (1 point) criteria: - Do not develop buildings on portions of sites that meet any one of the following Prime farmland as defined by the American Farmland Trust Land whose elevation is lower than 5 feet above the elevation of the 100-year flood as defined by FEMA Land which provides habitat for any species on the Federal or State threatened or endangered. Within 100 feet of any wetland as defined by 40 CFR, Parts 230-233 and Part 22, OR as defined by local or state rule or law, whichever is more stringent Land which prior to acquisition for the project was public parkland, unless land of equal or greater value as parkland is accepted in trade by the public landowner (Park Authority projects are exempt) SLC+ additional criterion: - Land that provides habitat for significant populations of migratory birds, or that is of riparian or other rare habitat type for which SLC plans seek long-term preservation, restoration, or public space corridor rights. Technologies & Strategies During the site selection process, give preference to those sites that do not include sensitive site elements and restricted land types. Select a suitable building location and design the building with the minimal footprint to minimize site disruption. Strategies include stacking the building program, tuck-under parking, and sharing facilities with neighbors. SLC+ Technologies & Strategies Salt Lake City should prepare and keep current a GIS database and set of maps, conveniently accessible to Planning staff and public, to inventory, track and serve as basis for planning of LEED Credit 1 and SLC+ criteria for strategic siting. Transferable development rights (TDRs) should be thoroughly developed as devices to offer alternatives to property owners wishing to develop land in critical areas (e.g., Northwest Quadrant, Emigration Canyon, Jordan River Corridor), encouraging dense cluster development or, where feasible, incremental preservation of complete habitat, farmland, floodplain, wetlands, parkland or public trails areas. SLC land exchange bank, acquiring infill development areas to offer as alternatives in trade for criteria properties proposed for development. Sites_v10.doc 5 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 2 Urban Redevelopment Intent Channel development to urban areas with existing infrastructures, protecting greenfields and preserving habitat and natural resources. SLC+ Intent Channel development to urban areas with existing infrastructures, protecting greenfields and preserving habitat and natural resources. Wherever possible, choose and utilize a site to facilitate infill development and adaptive reuse of existing facilities, as alternatives to “centrifugal” or “sprawl” development, waste of embodied energy and previously developed resources inherent in existing facilities, and in order to encourage compact growth patterns, which in turn support balanced transportation options, mixed-use development, walkability and other ‘SLC LEED+’ functions and values. Requirement Credit 2.0 (1 point) Increase localized density to conform to existing or desired density goals by utilizing sites that are located within an existing minimum development density of 60,000 square feet per acre (2 story downtown development). Technologies & Strategies During the site selection process, give preference to urban sites with high development densities. Quantify the development density of the project as well as the surrounding area. Sites_v10.doc 6 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 2.1 (1 point) Increase Credit for 2.0 Downtown Infill (SLC+) Award an additional point for LEED Credit 2.0, for Downtown, highest density infill. SLC+ Intent Areas qualifying for this credit are rare in Salt Lake City, found only in very limited parts of the core downtown. SLC+ desires to make siting in qualifying-density areas additionally attractive. Cost is often greater and administrative obstacles more complex to develop in downtown area, warranting additional incentive credit. Credit 2.2 (1 point) Neighborhood and Downtown-Margin Infill (<60,000 sf/ac) (SLC+) Increase neighborhood or downtown-margin compactness by utilizing vacant or available sites that are located in previously developed areas. SLC+ Intent SLC needs, and many neighborhoods can benefit from, significant infill in existing lower-density neighborhood centers, along present and future transit corridors, and in relatively low-density areas around the City center. This credit is to reward an intermediate stage of urban infill. SLC+ Technologies & Strategies Develop database, in GIS software environment, of floor-area ratio (FAR), number of dwelling units, and other spatial measures of density, for each property in the City. Utilize GIS to analyze existing densities and to plan density goals for downtown, downtown margins, neighborhood centers, transit and pedestrian corridors, and urban edges. Develop financial incentives and assistance programs to induce site choices that contribute to planned compactness goals. Develop outreach for businesses, individuals and institutions seeking sites to educate and inform about benefits of siting in existing urbanized areas, in coordination with City Planning density goals and objectives. Sites_v10.doc 7 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 2.3 (1 point) Adaptive Reuse of Existing Buildings (SLC+) Reuse an existing building or buildings, or an appropriate, existing facility for at least 30% of new facility requirements. SLC+ Intent Beyond materials, embodied energy and resource preservation and reuse, encourage preservation of existing buildings (“whole buildings” preservation for historical value, neighborhood landscape/streetscape, social ‘place’ and interrelationships, etc.) instead of short-cycle replacement or choice of peripheral sites. SLC+ Technologies & Strategies Create and maintain a readily accessible database/catalog of existing buildings that are available, or that could be induced to be available, for adaptive reuse at sites that contribute to City Planning Dept. goals and objectives. Develop incentives, including financial and design support tools, to induce choice of existing buildings over undeveloped sites. Sites_v10.doc 8 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 2.4 (1 point) Siting for Energy Efficiency and/or Renewable Energy Choose a site and orientation of building or facility to optimally develop building passive solar-thermal, solar-electric, site cooling, or other passive or active, orientation-critical or site-specific energy technology potentials. SLC+ Intent Site choice and building orientation are the crucial basis for the energy efficiency, passive and active solar, and other renewable energy technologies covered in LEED 2.0 Energy & Atmosphere Chapter, and in the SLC+ enhancement of that Chapter. Providing a single, additional point to incent attention to this factor is inadequate, relative to its environmental performance significance, but it provides a beginning. Sites_v10.doc 9 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 2.5 (1 point) Urban Archeology, Prehistory and History (SLC+) Analyze and record site prehistory (paleontology, archeology, or other significant prehistoric remnants) and/or history on the site. Integrate what is learned into monuments or informational edifice elements. Assure that appropriate governmental agencies (e.g., State Historical Preservation Office, US Geological Survey, State Paleontologist, State Archeologist, etc.) are notified of any discoveries prior to further excavation, filling or other construction operations. Assure that competent, licensed (where required by law) personnel are engaged for excavation and documentation of physical remains, and make available all artifacts to appropriate public institutions for expert conservation, preparation and exhibition. Utilize significant finds in place names, where possible, and in public information signage to share awareness of knowledge acquired. SLC+ Intent Encourage shared awareness of prehistorical and historical context in which City development occurs. Create incentives for participation in common access to well-developed information. SLC+ Technologies & Strategies Integrate prehistory and history into property databases. Include information in City literature, signage, walking tour guides, events. Develop financial and motivational incentives (awards, ceremonies, etc.) for conscientious performance of this criterion. Sites_v10.doc 10 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 3 Brownfield Redevelopment Intent Rehabilitate damaged sites where development is complicated by real or perceived environmental contamination, reducing pressure on undeveloped land. SLC+ Intent Incent commitment to Brownfields sites more closely in proportion to time and cost differentials between clean sites development and Brownfields. SLC has many areas near the City Center that qualify as Brownfields, but which will be expensive, time-consuming and possibly risky to purchase and develop. It is critical to downtown vitality and to bridging of east-west disconnectivity that all Brownfields sites be utilized to highest possible planning expectations. LEED 2.0 credits are insufficient, even when supported by tax incentives, to motivate redevelopment of many, if not most, of these sites. Credit 3.0 (1 point) Develop on a site classified as a Brownfield and provide remediation as required by EPA’s Sustainable Redevelopment of Brownfields Program requirements. Credit 3.1 (2 points) Develop on a Brownfield site greater than one acre but less than five acres. Credit 3.2 (3 points) Develop on a Brownfield site greater than five acres but less than ten acres. Credit 3.3 (4 points) Develop on a Brownfield site greater than ten acres. Technologies & Strategies During the site selection process, give preference to Brownfield sites. Identify tax incentives and property cost savings by selecting a Brownfield site. Adopt a site remediation plan and clean up the site using remediation strategies such as pump-and-treat, bioreactors, land farming, and in-situ remediation. SLC+ Technologies & Strategies City should develop and maintain a database of candidate, qualifying Brownfields sites, with as much information about development parameters as may be convenient to potential developers. City should support liability relief and clean-up closure measures to provide a potential Brownfields buyer/developer with reasonable legal protection from damage claims, after agency verification of successful cleanup. City should require a formal plan, to include a comprehensive analysis of the project, showing the following, at minimum: - all significant impacts, in addition to environmental issues - benefits and neighborhood ramifications of redeveloping the Brownfield - how the development implements or complements the City’s area master plan Salt Lake City will provide a central resource of incentives, assistance and lists of EPA and RDA loans and grants available. The potential for local tax incentives and loan programs will be investigated with City assistance. Sites_v10.doc 11 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 4 Alternative Transportation Intent Reduce pollution and land development impacts from automobile use. Requirement Credit 4.1 (1 point) Locate building within ½ mile of a commuter rail, light rail or subway station or ¼ mile of 2 or more bus lines. Credit 4.2 (1 point) Provide suitable means for securing bicycles, with convenient changing/shower facilities for use by cyclists, for 5% or more of building occupants Credit 4.3 (1 point) Install alternative-fuel refueling station(s) for 3% of the total vehicle parking capacity of the site. Liquid or gaseous fueling facilities must be separately ventilated or located outdoors Credit 4.4 (1 point) Size parking capacity not to exceed minimum local zoning requirements AND provide preferred parking for carpools or van pools capable of serving 5% of the building occupants, OR add no new parking for rehabilitation projects AND provide preferred parking for carpools or van pools capable of serving 5% of the building occupants Technologies & Strategies Perform a transportation survey of future building occupants to identify transportation needs. Site the building or facility near mass transit and design the building with transportation amenities such as bicycle racks and showering/changing facilities, alternative fuel refueling stations, and carpool/ van pool programs. Also consider sharing transportation facilities such as parking lots and refueling stations with neighbors. SLC+ Technologies & Strategies Provide “ universal-access” transit passes for building occupants, including construction workers. Encourage creating secure accommodations for other small, zero-emission vehicles, in addition to bicycles. Consider utility vehicle sharing programs among tenants/occupants and neighbors. Narrow excessively wide streets, using traffic calming devices and markings, while preserving bicycle lanes, emergency access and snow storage. Sites_v10.doc 12 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 5 Reduced Site Disturbance Intent Conserve existing natural areas and restore damaged areas to provide habitat and promote biodiversity. Requirement Credit 5.1 (1 point) On greenfield sites, limit site disturbance including earthwork and clearing of vegetation to 40 feet beyond the building perimeter; 5 feet beyond primary roadway curbs, walkways and main utility branch trenches; and 25 feet beyond pervious paving areas that require additional staging areas in order to limit compaction in the paved area; OR, on previously developed sites, restore a minimum of 50% of the remaining open area by planting native or adapted vegetation. Credit 5.2 (1 point) Reduce the development footprint (including building, access roads and parking) to exceed the local zoning’s open space requirement for the site by 25%. Technologies & Strategies Perform a site survey to identify site elements and adopt a master plan for development of the project site. Select a suitable building location and design the building with the minimal footprint to minimize site disruption. Strategies include stacking the building program, tuck-under parking, and sharing facilities with neighbors. Establish clearly marked construction boundaries to minimize disturbance of existing site and restore previously degraded areas to their natural state. SLC+ Technologies & Strategies Credit 5.1, on sites with significant trees, limit site disturbance, including earthwork and clearing of vegetation, to the limits allowed by preserved shade tree drip line and root extent, as required for each tree. If building plans call for excavation near large trees, consult a certified arborist, develop a tree preservation plan, and adhere to the plan rigorously. Keep excavations well clear of root zone, and maintain watering for tree stress reduction, as recommended by arborist. Do not stockpile materials or maneuver or park large equipment within drip line of large trees. Construct water-retention basin around trees during construction, while normal water systems are out of order, and water according to schedule directed by arborist. Sites_v10.doc 13 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 5.3 (2 points) Vegetation Preservation and Maintenance Plan and Training Assess existing vegetation and formulate a plan for site utilization that optimizes preservation of existing trees, shrubs and other important vegetation. Engage a certified arborist or tree appraiser to visit the site to determine what should be saved and protected and what can be removed, with penalties for failure to implement the plan. Based on the preservation plan, protect trees with sturdy fencing and a water catchment placed at or outside of dripline (not just around trunk). Inspect on a regular basis to ensure maintenance of protective measures and periodic watering, as recommended in the arborist’s plan. Excavations which may disturb or cut roots within drip line will be avoided or, where unavoidable, addressed case-by-case in the arborist’s preservation plan, and all special instructions followed. SLC+ Intent Introduce sufficient training and knowledge into planning, design, construction, operations and maintenance to dramatically decrease tree & shrub mortality, and to increase growth and urban forest health. Present maintenance services and maintenance personnel are guilty of unacceptable practices, such as girdling young trees with weedeaters, compacting soil under trees during construction, encroaching inside drip lines with paving (by design) and construction staging, and careless operation of heavy equipment such as backhoes and cranes. SLC+ Technologies & Strategies Develop model training guides, design outlines, construction documents guidelines (for specifications and contract documents modifications to accomplish these objectives). Train City staff, including planners, building inspectors and environmental staff in essentials of both enforcement and outreach for Credit optimization. Sites_v10.doc 14 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 5.4 (1 point) Wetlands and Riparian Protection Plan. (SLC+) Preserve site wetlands and riparian areas, minimizing disturbance to existing soils, hydrology and vegetation communities by preparing a wetlands and/or streamside zone protection and management plan to prevent damage during construction and subsequent use. Assure that other site landscaping and landscaping maintenance activities do not hydrologically alter or chemically impact wetlands and riparian areas, either on site or on sites downstream. SLC+ Intent Whereas Credit 1.0 for Site Selection offers only a point for avoidance of wetlands, there is no requirement in LEED 2.0 for developing a protection and management plan. Some of the City’s most ecologically critical remnant areas are in the crosshairs of development, especially the Northwest Quadrant, near the Great Salt Lake’s south shore, and Emigration Canyon/Creek, one of the City’s last functioning riparian ecosystems. In the latter case, a developer has tried to muscle past the Corps to build, literally, on the creek. Because of steep-sided stream profile, the ‘100 feet’ restriction in Credit 1.0 not only is not meaningful in most places in that site; it will be ignored by some property owners, who have been taught to resent idea of wetlands as they cry “taking.” The arbitrary restrictions in Credit 1.0 also won’t be very meaningful around playa areas (often not technically ‘wetlands’ but just as ecologically important) in the Northwest Quadrant, near the Great Salt Lake, where all the dozens of species of migratory birds that nest here by the millions (really) nest on the ground. More protection can be accomplished through understanding and through responsible, accountable development of a plan. SLC+ Technologies & Strategies Salt Lake City can contribute immensely to habitat, species and wildlife diversity and populations protection by conducting and maintaining a reasonably thorough database, with GIS capabilities to facilitate comparative overlay with other development events and trends, and to perform specific spatial queries. The ecological picture will change in response to many factors other than surface development: air pollution, global warming, recreational use, watershed management, wildlife restoration programs, weather cycles, transportation infrastructure, etc. All of these variables, and others that may emerge, must be understood. Sites_v10.doc 15 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 5.5 (1 point) Survey and assess wildlife species and ecosystems. (SLC+) Engage a certified ecologist to examine the site for “threatened and endangered” species, as well as for important populations of wildlife. Where nesting migratory waterfowl, shorebirds or neotropical songbirds are found to use the site, avoid disturbance and formulate a plan for maintaining critical habitat elements. SLC+ Intent Where sites possess natural ecosystems or ecosystem elements, functions or values (identified in the Sustainable Sites site characterization), these ecosystem elements are likely to be of great significance because of their scarcity. The vegetation community and hydrological system are critical to almost all wildlife communities that may occupy a site in the Salt Lake City area. Seasonally, it may even be necessary to avoid any activity on site to allow reproductive cycles to play out, especially nesting of birds. SLC+ Technologies and Strategies Sites_v10.doc 16 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 6 Stormwater Management [addressed in Water Efficiency Chapter] Sites_v10.doc 17 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 7 Landscape and Exterior Design to Reduce Heat Islands Intent Reduce heat islands (thermal gradient differences between developed and undeveloped areas) to minimize impact on microclimate and human and wildlife habitat. SLC+ Intent Plan and design plantings to support City aesthetic and quality-of-life values according to the Urban Forestry Plan, and to enhance ecological functions and values through diversity and longevity and urban plants. Requirement Prerequisite 2 Planting and Maintenance Plan and Training. With the guidance of City Forester or qualified arborist, develop a planting and maintenance plan and supporting training program to assure that initial plantings are properly done, fully considering site soils, appropriate soil amendments, microclimate variations, and that best maintenance and irrigation practices contribute to the biological productivity of the site, avoiding damaging or destructive materials and maintenance practices. Plan should assure that tree species, at maturity, are compatible with site uses, available space, streetside sight lines and traffic control devices, signage, and with overhead and underground utilities. Include construction/vegetation plan (coordinated with Credit 5) to guide preconstruction pruning to minimize damage from footing/foundation excavations, cranes and heavy machinery and construction chemicals, anticipating water retention basin creation, dry season irrigation schedules, grade change impacts, stormwater runoff control, and other possible construction damage to trees, shrubs and sensitive native vegetation. SLC+ Intent Distinct from the plan required under Credit 5, this plan addresses new plantings, their planning, design, execution and maintenance. This is one of the most severely neglected of all construction aspects, requiring head-on management. Credit 7.1 (1 point) Provide shade (within 5 years) on at least 30% of non-roof impervious surface on the site, including parking lots, walkways, plazas, etc.; OR, use light-colored/high-albedo materials (reflectance of at least 0.3) for 30% of the site’s non-roof impervious surfaces: OR place a minimum of 50% of parking space underground; OR use open-grid, pavement system (net impervious area of less than 50%) for a minimum of 50% of the parking lot area. Sites_v10.doc 18 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 7.2 (1 point) Use ENERGY STAR Roof-compliant, high-reflectance and high emissivity roofing (initial reflectance of at least 0.65 and three-year-aged reflectance of at least 0.5 when tested in accordance with ASTM E903 and emissivity of at least 0.9 when tested in accordance with ASTM 408) for a minimum of 75% of the roof surface, excluding mechanical equipment, walkways, skylight areas, etc.; OR install a “green” (vegetated) roof for at least 50% of the roof area. Sites_v10.doc 19 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 7.3 (1 point) Additional Non-Roof Shade Provide shade (within 5 years) on at least 50% of non-roof impervious surface on the site, including parking lots, walkways, plazas, etc. SLC+ Intent With or without the threat of global warming, and its implications for exacerbating urban heat islands, we can and must do better than the present landscape, in which > 65% of SLC is hard-surfaced not counting streets, much of the hard, heat-radiating surfaces in support of the automobile. This is a critical feedback loop for global climate change. Sites_v10.doc 20 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 7.4 (1 point) Additional Roof and and Non-Roof, Paved-Area Shade Increase shade on roofs, parking areas and walkways by use of trellises and pergolas (e.g., reclaimed lumber, durable composites) to shade an additional 20% or more of impervious paved, non-roof and low-reflectance roofed areas. Technologies & Strategies Shade constructed surfaces on the site with landscape features and minimize the overall building footprint. Consider replacing constructed surfaces (i.e., roof, roads, sidewalks, etc.) with vegetated surfaces such as garden roofs and open grid paving or specify light-colored, high-albedo materials to reduce the heat absorption. SLC+ Technologies & Strategies Subject to seismic factors and corollary structural material requirements, and to water conservation constraints appropriate to site microclimate, develop all feasible means of heat-island reduction. Recommended Strategies: Start early in the planning process with appropriate expertise to formulate a plan, maintain expertise through design and construction, and carefully train operations/management/maintenance personnel in best vegetation maintenance and improvement practices. Limit number of parking spaces to the minimum number the City will allow for transit-dependent, walkable access to site for permitted use. Use a plant-supporting open pavement system. Use high-emissivity (reflective) roofing for 100% of roof surface, except for mechanical equipment, walkways, skylights or light monitors, and other necessary rooftop appurtenances. Where installing a ‘green’ roof, use low-water vegetation and appropriate, water-conserving irrigation. Analyze ‘green’ roof benefits in light of seismic design impacts and added structural requirements. Shade roof and paved areas as much as possible. Use of photovoltaic panels (PV) for electricity generation also shade surfaces on which they are placed. Sites_v10.doc 21 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 8 Light Pollution Reduction Intent Eliminate light trespass from the building site, improve night sky access, and reduce development impact on nocturnal environments. Restrain noise disturbance from one site to another. Requirement Credit 8.1 (1 point) Do not exceed Illuminating Engineering Society of North America (IESNA) footcandle level requirements as stated in the Recommended Practice Manual: Lighting for Exterior Environments, AND design interior and exterior lighting such that zero direct-beam illumination leaves the building site. Technologies & Strategies Adopt site lighting critical to maintain safe light levels while avoiding off-site lighting and night sky pollution. Minimize site lighting where possible and model the site lighting using a computer model. Technologies to reduce light pollution include full cutoff luminaries, low-reflectance surfaces, and low-angle spotlights. SLC+ Technologies & Strategies Use light-colored and dark-colored paving strategically, where appropriate, to reduce nighttime illumination requirements and consequent energy consumption, render illumination more effective, and to contribute synergistically to energy conservation and to heat-island reduction) without increasing unwanted reflections into sky. Use plantings strategically to screen sky from fugitive, reflected illumination. Put ‘hats’ on historic, downtown ‘Indianhead’ fixtures to block up-cast light. Sites_v10.doc 22 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 9 Noise Pollution Reduction Intent Restrain noise disturbance from one site to another. Requirement Credit 9.0 (1 point) Utilize building noise containment, sound-absorbing plantings, berms or constructed sound barriers to limit noise penetration from site, and to reduce unwelcome noise from streets or adjacent sites. SLC+ Technologies & Strategies Use plantings and landscaping for noise reduction, and choose materials and surfaces with high noisereduction coefficients (NRC), subject to exterior weather-resistance and other architectural objectives. Sites_v10.doc 23 4-7-02/I. Weber Salt Lake City High Performance Building Initiative Leed 2.0 – SLC+ Credit 10 Co-Location Intent Encourage synergistic, functional facility relationships and mixed-use adjacencies, minimize quantitative spatial requirements, and maximize efficiencies of energy and resources through proximity and sharing of systems. Foster diversified economic relationships for mutual advantage. Increase public green spaces, such as parks and shaded walkways by strategically associating commercial and institutional landscaping with residential developments. Requirements Credit 10.1 (1 point) Site Co-Location. Share site by two or more building projects to reduce scale of area and resources consumed. Credit 10.2 (1 point) Eco-Industrial Co-Location. Associate on site two or more appropriate industries or businesses that benefit economically and environmentally from utilization of each other’s waste heat, process water, materials flows or other resources or by-products. Credit 10.3 (1 point) Mixed-Use Co-Location. Place appropriate businesses, industries, services and public-service organizations in site-sharing relationship in mixed-use neighborhood, providing walkable-access and/or transit access to employment or services, for mutual benefit. SLC+ Technologies & Strategies Reviving mixed-use adjacencies that characterized vibrant cities until planning practices in recent decades segregated land uses, site co-location encourages appropriate proximity of uses at all scales, encourages compactness, efficiency and diversity typical of sustainable cities. Based on recognition that there is no waste in nature, “eco-industrial” or “industrial ecology” co-location develops economic and resource synergies to cluster industries and businesses so each benefits symbiotically from the presence and waste products of the other. Mixed-use co-location encourages residence near employment, goods and services; economic production near labor resources and needed services; and service opportunities near markets, both industrial/manufacturing and residents. Non-profit organizations can be paired with for-profit businesses, and all manner of “clean” businesses can associate within a site. Within environmental health and quality-oflife constraints, co-location development can contribute to many/all other SLC LEED+ objectives. Sites_v10.doc 24 4-7-02/I. Weber
