Abstract
Street lighting design aims to ensure adequate night visibility conditions for both
vehicular and pedestrian traffic as well as to improve security conditions for
persons, goods and property in the neighbourhood. In addition to this, and in
order to meet concerns about environmental protection and sustainable
development, the design of street lighting should take into account the
optimization of its energy efficiency, as excessive energy usage is associated
with an increase in polluting emissions, namely CO2. Considering that street
lighting generally presents a significant consumption of electricity that is often
possible to reduce, the use of good design practices which will maximize the
efficiency of lighting equipments and accessories as well as minimize the
upward light emissions and adjust the intensity of lighting according to outdoor
needs is crucial. The main goal of this work is to present a new simple tool
which can assess street lighting performance in the context of energy efficiency.
Three indicators were developed: one to evaluate lighting performance and two
others to evaluate energy performance. These indicators were quantified and
combined according to weighting and aggregation procedures, resulting in a
synthetic score for the street lighting design. The assessment tool was applied to
a business park located in Viana do Castelo, in Portugal, and the results are
discussed.
Keywords: street lighting, street lighting design, street lighting assessment,
