Energy Conservation at Sun
Common sense and flexibility are standard operating procedures for
Sun's energy conservation efforts. Starting in 1995, the company
initiated a sensible, easy-to-implement plan to optimize energy
consumption.
In 1996, the company became a partner in the Energy Star
Buildings Program, a voluntary partnership between commercial energy
users and the US Environmental Protection Agency. The plan is
implemented through incremental changes that are already resulting in
real energy savings, including:
- Time clocks and photo cells control outside lighting
- Energy saving devices such as programmable thermostats
regulate heating and air-conditioning systems, and new or retrofitted
LED-based exit signs save electricity.
- Adjustable motion sensors to optimize indoor lighting
control and turn off office lighting when the office is unoccupied.
- Sun's desktop workstations (of which the company uses many
thousands internally) utilize Energy Star Power Management™ software
that allows the computer to power down and go to a lower
energy-consuming state when idle.
- Deployment of Sun's new SunRay technology that replaces
conventional desktop computers. To read more about his interesting and
environmentally friendly product line click here.
- Devices installed at Sun's campuses that work with an
occupancy sensor in each office to turn off electrical equipment
plugged into some outlets.
- Switching to ultra-low energy flourescent lamps in offices.
- In 2004, the company's Burlington, Mass campus completed
several energy
efficiency initiatives that earned the company nearly $500,000 in
rebates from the local utility company in addition to reducing Sun's
operating costs. The installation and operation of the upgraded
equipment and systems will reduce the campus' energy consumption by
well over one million kilowatt hours (kWh) per year.
The upgrades include:
-- Reprogramming the automated controls system to more efficiently
operate the chillers in the central utility plant.
-- Installation of a heat exchanger in the central plant, which makes
use of cold outdoor air in the winter to provide "free cooling" of the
chilled water system.
-- Energy efficient light fixture selections and lighting control
measures for other buildings
-- Reprogramming rooftop air handling units on each building for more
efficient operation.
