Abstract
In this study, the energy consumption of two relocatable classrooms located on the southern portion of the campus of Chapel Hill High School in Chapel Hill, NC is investigated. One classroom, the control, was specified and purchased by the Chapel Hill-Carrboro City School System. The other is a performance enhanced classroom designed by the Florida Solar Energy Center and purchased by the North Carolina Solar Center. Both classrooms are 24' by 40' modular structures, completely underpinned, and located adjacent to one another for a side by side comparison. The energy consumption and indoor conditions of each classroom are monitored by a data-logging system that also records outdoor conditions via a weather station.
The performance enhanced classroom is equipped with a 3 ton, SEER 12 heat pump controlled by a Bard CS2000 unit, six skylights, increased insulation and envelope sealing, a demand control ventilation system with an energy recovery wheel, and a day lighting system controlled by occupancy sensors. The control classroom is equipped with a wall-mounted 10 kW electric furnace/air conditioning system. A programmable thermostat was also installed in the control classroom after two months of data was collected. A building model is prepared using the Energy-10 software package to estimate the impact the various design changes have on the energy consumption of each classroom.
