Frederick County Public Schools’ goal for this new middle school was to create a progressive campus for an expected enrollment of 900 students in the County’s under-served rural community. It set out to develop a prototype school that was not only student- and community-centric but that was a model of energy and water efficiency and incorporated the building’s sustainable infrastructure into the curriculum. The project was driven by an energy usage target of less than 30 kBtu/sf/yr.
The project team utilized an integrated design process to maximize cost and schedule efficiencies and produce an exceptionally energy-efficient building. 2RW performed energy modeling early in the project to enable data-driven comparisons of building shell and HVAC alternatives. The data facilitated design decisions that minimized heating and cooling loads and reduced HVAC system requirements. 2RW also helped evaluate and select energy-efficient envelope, HVAC, plumbing, and lighting solutions, including a hybrid geothermal HVAC system with an expected return on investment of fewer than 10 years.
The site’s rural location posed a challenge for water generation and treatment, as it was not served by municipal utilities. 2RW worked closely with the water treatment and management consultant to leverage an artesian well and an innovative on-site wastewater treatment system, enabling the school to source, treat, and relieve all water on-site and achieve Net Zero Water status.
2RW designed the MEP/FP infrastructure for the school which includes learning and office spaces, cafeteria, kitchen, gym, locker rooms, auditorium, and library. The design maximizes natural and LED lighting, incorporates “green light” sensors that notify students of the best times to open windows for fresh air, and augments the curriculum with opportunities to view and study the geothermal system.
In its first year, the school consumed just 26.9 kBtu/sf of energy — 39% of the energy use of comparable secondary schools. Energy consumption is projected to drop more after the building has been in use for some time with operational fine tuning. With an additional investment of approximately $3 million (just 6.9% of the original construction cost), the building could be converted to Net Zero Energy.
