Many partners provide information on sustainable
lighting design for lighting designers and operators. One of them is the German
Energy Agency (dena), which offers online
tools for energy-efficient indoor and outdoor
lighting (www.lotse-innenbeleuchtung.de /
www.lotse-strassenbeleuchtung.de). At
these sites, municipalities and companies
find lots of practical tips and tools for every
phase of a lighting project – from planning
through to operation.
