State-funded buildings in New Hampshire over 25,000 sq. ft. must comply with ASHRAE Standard 189.1-2009 and High Performance Green Building Standards except for sections 4, 9, and 10 to the furthest extent possible without hindering the facility’s ability to recoup the costs of meeting these requirements over a 10 year period. This standard addresses site sustainability, water use efficiency, energy efficiency, indoor environmental quality (IEQ), and the building’s impact on the atmosphere, materials, and resources.There are some buildings that are exempt from this regulation, including temporary structures, buildings without HVAC systems, and some others.
