Sustainable Sites (Continued)
Light Pollution Reduction (1)
1.C8
Intent:
Eliminate light trespass from the building site, improve night sky access, and reduce development impact on
nocturnal environments.
Requirement:
Do not exceed Illuminating Engineering Society of North America (IESNA) footcandle level requirements as
1
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
Consult IESNA Recommended Practice Manual: Lighting for Exterior Environments for Commission Internationle
/Strategies:
de I'Eclairage (CIE) zone and pre and post curfew hour descriptions and associated ambient lighting level
requirements. Ambient lighting for pre-curfew hours for CIE zones range between .01 footcandles for areas with
dark landscapes such as parks, rural, and residential areas, and 1.5 footcandles for areas with high ambient
brightness such as installation/base areas with high levels of nighttime activity. Design site lighting and select
lighting styles and technologies to have a minimal impact off-site and minimal contribution to sky glow. Minimize
lighting of architectural and landscape features. Exterior lighting should be consistent with security lighting
requirements.
Optimize Site Features
1.C9
Intent:
Optimize utilization of the site's existing natural features and placement of man-made features on the site.
Requirement:
Perform both of the following:
1
Maximize the use of free site energy.
Plan facility, parking and roadways to "fit" existing site contours and limit cut and fill.
Technologies
Evaluate site resources to ascertain how each can enhance the proposed project and visa versa. Work to
/Strategies:
maximum advantage of the site's solar and wind attributes. Use landscaping to optimize solar and wind
conditions and to contribute to energy efficiency; Locate and orient the facility on the site to optimize solar and
wind conditions.
Facility Impact
1.C10
Intent:
Minimize negative impacts on the site and on neighboring properties and structures; avoid or mitigate excessive
noise, shading on green spaces, additional traffic, obscuring significant views, etc.
Requirement:
Cluster facilities to reduce impact, access distance to utilities and sufficient occupant density to support mass
1
transit.
Collaborate with installation/base and community planners to identify and mitigate potential impacts of the
1
project beyond site boundaries, and transportation planners to insure efficient public transport.
Technologies
Involve local/regional planners and community members in installation/base master planning processes.
/Strategies:
Recognize the context and the impact of a project beyond site boundaries, and integrate it with the larger
installation/base/community context/land use.
Site Ecology
1.C11
Intent:
Identify and mitigate all existing site problems including contamination of soil, water, and air, as well as any
negative impacts caused by noise, eyesores, or lack of vegetation, enhancing or creating new site habitat.
Requirement:
Develop site environmental management and mitigation plan.
1
Technologies
Understand site and surrounding ecosystem interdependence and interconnectivity. Plan landscaping scheme to
/Strategies:
incorporate biodiversity. Preserve/enhance existing trees, hydrological features, ecosystems, habitats, and
cultural resources. Increase the existence of healthy habitat for native species. Reintroduce native plants and
trees where they have been destroyed by previous development.
