Harry Street Elementary

Harry Street Elementary was originally built in 1890, then replaced in 1906 and again in 1922 with a 22,000 square foot building housing 12 classrooms and an auditorium—now “B” hall. In 1941, a 12,000 square foot addition created “A” hall with four classrooms, an office, and a health room. In 2000, a 12,000 square foot addition formed “C” hall, adding a multipurpose room, kitchen, library, and four classrooms, along with major HVAC upgrades. A final 7,500 square foot addition in 2010 created “D” hall with five classrooms and restrooms. The school currently totals approximately 49,997 square feet.

Harry Street Elementary has significant opportunities for energy and operational savings. The graph above shows the baseline utility cost and projected future utility expenditure if energy conservation measures, as identified by Navitas' preliminary site audits, are implemented. Currently, this building spends approximately $50,770 annually (Baseline) on electricity and gas, with a baseline energy usage index (EUI) of 42.3. A building with similar systems and operations can have variable energy usage when efficiency measures are upgraded, depending on the occupancy load. The energy usage index can range between 30–40 EUI. The projected numbers are based on conservative efforts and reflect the district reducing the energy usage index to 30, which would result in total utility dollar savings of approximately $282,000 in energy costs over 15 years. This does not include additional operational dollar savings that would be achieved by implementing newer, more efficient systems.
