UC Davis Selects Induction Based on New
Design Criteria
Released by the Department of Energy
Research
shows that brighter is not always better in exterior lighting applications. According
to an exterior lighting guide published by the Department of Energy (DOE) in
collaboration with the Federal Energy Management Program, Lawrence Berkeley
National Laboratory, and the California Lighting Technology Center at UC Davis,
studies have shown that excessive lighting can lead to glare and over-illumination
– sometimes making people more vulnerable to criminal activities.1
The
guide was designed to assist facilities managers in choosing the correct
luminaires and practices for their spaces to reduce energy use while making
their spaces more visually appealing and safer for visitors. “When designing
exterior lighting systems, it is the quality of light instead of the quantity
of light that is typically related to safety.”1
Because exterior lights are typically on for
extended periods of time, it is important to install energy efficient fixtures.
Combining high quality lighting technologies with SMART bi-level sensor
controls will reduce energy while saving money and increasing safety. To
demonstrate this, energy-efficient EverLast® induction shoe box parking lot
fixtures with bi-level occupancy controls that dim to low light levels during
unoccupied periods were recently installed at UC Davis's School of Veterinary
Medicine as part of a campus-wide commitment to reduce electricity use by 60%
by the end of 2015. The EverLast® fixtures produce a balanced light
distribution that provides enhanced security to students and faculty while
helping the campus reach its goal of reducing energy consumption.
Two
metrics are commonly used to determine lighting quality: correlated color
temperature (CCT) and color rendering index (CRI). CCT describes the color
appearance of a light source and is measured in Kelvin (K) degrees. CCTs
ranging between 5000-6000K deliver a white light that is better for identifying
potential threats at night. CRI is used to describe color rendering accuracy of
a light source and is measured on a scale ranging up to 100. A light source
with a high CRI denotes good color rendering ability, which is important for
safety and security.
Lighting that has a
CCT ranging between 5000-6000K and a high CRI is often perceived as brighter,
even if the light source provides fewer lumens per watt. This perception is due
to the light being high quality. As a
result, it is important to understand who, when, and why individuals will use
the space being lit, and adapt the lighting design to provide the type of illumination
that suits the needs of the expected occupants.1
