This new greenhouse was built last year. It took the place of an older, less efficient one.
"When we tore the old greenhouse down which was comprised primarily of concrete glass and aluminum we recycled nearly 100% of the old greenhouse. So the construction debris was almost zero," says Grindle.
The new greenhouse was made from recycled materials too. "The whole glass itself is more than 20% recycled content," Gridnle adds.
And there's a high tech control system that limits the amount of energy used to heat and cool the greenhouse. Grindle says, "the building has a very advanced control system to operate. So we minimize the amount of energy we put into the building."
This greenhouse is part of a larger building project that will be certified green.
"As part of our leeds accreditation we have to continue to educate our students in sustainability practices and things we do here at the college. We are very committed to encouring more people to become sustainable," says Grindle.
