The Massachusetts Department of Environmental Protection (MassDEP) is on the hunt for new office space in Boston and Worcester, and is giving preferential treatment to potential landlords that keep it green.

A request for proposals (RFP) using new green guidelines that include strict property energy management and water conservation is now underway as MassDEP seeks new lease agreements for its central headquarters in Boston, and a regional office in Worcester, the agency said.

Proposals that include sustainable and green practices will receive preference in the state review process, adding an incentive for potential landlords to commit to affordable, progressive environmental practices.

The new green lease guidelines require landlords submitting proposals for MassDEP offices to equip the premises with energy management systems, meet water conservation standards for all new plumbing fixtures, and provide bicycle commuting facilities at their building, among other green measures. Six pages of environmentally friendly initiatives like these are included in MassDEP office leasing documents to encourage green proposals, contracts and agreements between the state and office building landlords.

"Businesses want to do the right thing – the green thing – to reduce their carbon footprint," said MassDEP Commissioner Laurie Burt. "By promoting the use of this unique Green Lease model, MassDEP is paving the way for other state agencies and local businesses that want to bring environmental sustainability to their commercial leasing options."

The guidelines were drafted in conjunction with the state Division of Capital Asset Management (DCAM), which is responsible for major public construction and real estate services for the Commonwealth.
