East Hardin Middle School

The primary focus of the HVAC design on HCS East middle school was to provide a very energy-efficient building to reduce operating costs for this large middle school. Two-stage water-source heat pump units were located on the mezzanine level serving classrooms below. These units operate at part load capacities and reduce the amount of energy used when classrooms are minimally occupied. Energy recovery units with demand control ventilation provide fresh air for the entire facility.  Utilizing the mezzanine allows for equipment to be maintained without disrupting instruction.

Building security considerations included an interior and exterior video surveillance system, access-controlled doors complete with an emergency lockdown feature. The building entry is secured with card access control and IP security cameras throughout. The entire facility is protected by an addressable voice-evacuation fire alarm system and emergency lighting and life safety systems are powered by an on-site generator.

High-efficiency LED lighting systems are installed throughout the facility with automatic lighting controls utilizing occupancy sensors as well as automatic time of day scheduling, daylight harvesting and user-adjustable dimming controls. Color tuning lighting controls improve the learning environment of special needs classrooms on demand. Exterior lighting also incorporates motion sensor dimming for energy reduction without compromising campus security. A full-scale theatrical lighting system was provided for the 500-seat theater.
