N.H. Admin. Code § Ed 321.09
The utilization rate of a school building shall be calculated by dividing the design capacity by the educational capacity and expressing the figure as a percentage. A 100 percent utilization rate shall not be required. For a proposed new building or addition to an existing building, the educational capacity shall be calculated by dividing the design capacity by the planned utilization rate. For purposes of determining eligibility for school building aid, planned utilization rates shall not be less than 85% for high schools, 90% for middle schools, and 95% for elementary schools. The minimum utilization rate shall not apply when only one general purpose classroom is assigned per grade.
