Exterior Lighting Design <br />Cottages at Riverton <br />Exterior lighting for the Cottages at Riverton has been selected to enhance the aesthetics, safety, and <br />security of this neighborhood. In general, full cut -off lighting is used to reduce glare and to avoid light <br />trespass onto adjacent properties and into residences. Full cut -off lighting does not emit light above the <br />horizontal plane, instead, it directs light downward. An exception to this application is the lighting at <br />residential porches. In this case, a low- energy luminous fixture is provided to assist in wayfinding (i.e., <br />enter here) and provide a welcoming glow. <br />Light Sources: Lighting will utilize metal halide for post- mounted fixtures and compact fluorescent for <br />building- mounted fixtures to provide high quality white light. Using metal halide instead of high <br />pressure sodium (HPS) will provide better color rendering, <br />which can enhance the feeling of security. <br />Streets: Streets will be illuminated to levels as noted in the <br />Illuminating Engineering Society of North America IESNA) <br />Recommended Practice for Roadway Lighting. Streets <br />internal to the project will be lit to a minimum average <br />maintained illuminance of 0.4 footcandles, with a <br />maximum /minimum ratio not to exceed 6:1. <br />The fixture will a full cutoff luminaire, with a height of <br />approximately 15 feet. The selected fixture is the Eurotique <br />Munich Series. <br />IN <br />i <br />Street Lighting Luminaire <br />Walkways: Walkways will be illuminated to levels as noted in the IESNA <br />Recommended Practice for Exterior Environments. Walkways separate from <br />adjacent streets will be lit to a minimum average maintained illuminance of 0.5 <br />footcandles, with a maximum /minimum ratio not to exceed 10:1. <br />The fixture will be a full cutoff luminaire, with a height of approximately 12 feet to <br />reinforce a more pedestrian scale. The selected fixture is the Eurotique Munich <br />Series, with post -top mounting to provide design continuity throughout the project <br />while differentiating pedestrian -only spaces from streets. <br />Residential Entry: Lighting at residential entries will provide a soft, glowing <br />light. The selected fixture is the Visa Midland ceiling mount with compact <br />fluorescent lamping. <br />r <br />r <br />Pedestrian Post -top Luminaire <br />Residential Entry Luminaire <br />ATTACHMENT I <br />51 <br />
