IES DG-21-15 PDF Download

The IES DG-21-15 standard provides guidelines and criteria for designing lighting systems for residential streets. It emphasizes the importance of complying with local jurisdiction regulations for light levels and light trespass, as well as considering the preferences and needs of the community.

The document suggests using the ANSI/IES RP-8-14 American National Standard for Roadway Lighting as a reference, as it sets out the standards and criteria for roadway lighting. It is important for designers to meet these standards, along with local ordinances and concerns for landscaping design.

The standard highlights several objectives that should be achieved in a residential street lighting installation, including pedestrian and driver safety, obtrusive light control, minimized power usage, creating a pleasing neighborhood ambiance, reducing crime, and ensuring comfortable use of residential streets after dark.
