Montgomery County, Maryland, a suburban county bordering Washington DC with a population over 1 million, is the first county in the nation to pass an energy benchmarking law. Bill 2-14 was part of a package of nine energy bills unanimously passed by County Council on Earth Day, April 22, 2014. The law requires that owners of large nonresidential buildings benchmark energy use on an annual basis. The law was amended on November 17, 2015 with the passage of Bill 35-15. The amendments set the private sector building group deadlines six months earlier than they had been in the original Bill 2-14. The new dates are noted below.
All county-owned nonresidential buildings must benchmark by June 1, 2015. Private, nonresidential buildings greater than or equal to 250,000 square feet must comply with the law by June 1, 2016, while the deadline for private, nonresidential buildings greater than or equal to 50,000 square feet is June1, 2017. A licensed professional must verify benchmarking data before the first submission and every three years thereafter.
