Montgomery County is taking a major step forward to reduce greenhouse gas emissions and meet climate protection goals with today’s unanimous Council approval of Executive Regulation 21-15 AMII, which adopts the International Green Construction Code (IgCC) establishing green building code requirements.



“I commend the Department of Permitting Services for its persistence in pushing this code forward and I thank the County Council for its approval of the Executive Regulation,” said Montgomery County Executive Ike Leggett.

With adoption of the IgCC, Montgomery County establishes a baseline requirement that new, non-residential construction and additions of 5,000 square feet or more must be designed and constructed to reduce building energy use by at least 50% over the average commercial building energy consumption in the base year of 2000.

In addition to reducing energy consumption by 50%, projects must mitigate heat island impacts associated with development and divert at least 50% of construction and demolition waste material from landfills. This green building code is a critical step in meeting the County’s commitment to implementation of the County’s Climate Protection Plan.

“This green construction code will result in reduced energy spending for building users,” said Diane Schwartz Jones, director of the Department of Permitting Services. “It is essential to reduce environmental impacts from building-related greenhouse gases and places us on a path to leave a far better legacy for future generations.”

The requirements of the IgCC will take effect on Dec. 1, 2017 in Montgomery County.
