Best Practices

Illuminating a night-time landscape effectively and efficiently is an art and a science. The first line of defense for New Mexico's night sky and night-time environment is an informed community of architects and engineers. These professionals influence the number and selection of lighting fixtures for both new installations and renovations/retrofits on commercial and public projects, and in some cases large residential developments.

Many lighting engineers are members of the Illuminating Engineering Society of North America (IESNA), a professional organization dedicated to improving the lighted environment. The IESNA makes its design guides available for purchase by non-members. We recommend architects, engineers, contractors, developers, and decision makers for commercial and public facilities take advantage of these valuable resources. A selection of useful IESNA design guides and other design resources appears below.

In addition, we recommend the following general design guidelines:

Design Criteria for Good Outdoor Lighting
♦ Comply with applicable codes and outdoor lighting ordinances
♦ Design in accordance with IESNA recommendations
♦ Follow IDA (International Dark-Sky Association) information and guidelines
♦ Determine if it is really necessary for an area to be lit and then apply these four elementary concepts:
   1. Shield it
   2. Point it down
   3. Don't use more than you need
   4. Turn it off when you are done and not there
