HONOLULU(KHNL)- These days, more and more companies are going green.
One example is the University of Hawaii Medical School.
You can't tell by looking at it, but the glass windows are making a difference.
"All of the windows are coated with a reflective coating that keeps out heat but allows in sunlight," said Greg Takayama, UH spokesperson.
It's just one way the University of Hawaii Medical Building is helping the environment and its bottom line. Another way, is by using motion sensors in the classrooms. When students and professors leave, the lights automatically turn off after three minutes.
The building also features light shelves which sit just above the windows. They help to bring more natural light into the classrooms.
Then there's the air conditioning system. The ocean helps to cool it.
"There are two wells that are below our campus, 800 feet deep that bring up ocean seawater at a temperature of about 60 degrees," said Takayama.
That's cold enough to go through a chiller plant and help them save $300,000 a year. That's not all.
"They've received $213,000 in rebates so far," said Darren Pai, spokesperson for Hawaiian Electric.
HECO gives money to residential and commercial customers who try to improve their energy efficiency.
"We can have our engineers and customer service people work with you and figure out what's gonna be best for your project," said Pai.
HECO says there are resources and rebates available. Both can help you now and down the road.
