What is Daylighting?
Posted by Kaiden Douglass on in Engineering, Fundamentals, Sustainability
Daylighting is the controlled admission of natural light into a building to reduce electric lighting and save energy. Daylight can enter a space through several architectural elements, including windows, skylights, roof monitors, and clerestories. Each of these elements creates a daylighting zone, which must be controlled with a daylighting responsive lighting control system in order […]

Combating Light Pollution
Posted by Mike Ruff on in Engineering
Light trespass and light pollution are on the front burner of many municipalities in the U.S. due to the perception of wasted energy or impingement upon usage options of neighboring properties. There are new codified ordinances that restrict exterior light levels, pole heights, pole locations, lamp type/wattage, or watts/sq ft. The USGBC offers a Light […]

Electrical Engineering : What is Dirty Power?
Posted by Mike Ruff on in Engineering, Fundamentals
“Dirty power” is an abnormality in the power quality that is being delivered to a system. These abnormalities can include low power factor, voltage variations, frequency variations, and surges. All electrical systems are based on a supply of power at a certain voltage and frequency. Equipment and electronic devices are chosen based on this expected […]
