 Liberty Union Thurston Middle School

Liberty Union Thurston Middle School

Based on the 2007 OSFC Design Manual to achieve LEED Silver certification, a new education facility housing a middle school located near the existing elementary school was needed for the rapidly growing Liberty Union School District. The project achieved LEED Gold Certification in July 2013.

The HVAC system is a water source heat pump system which provides exceptional occupant control and comfort while also saving energy through its inherent energy recovery. This project included a 100% ground loop heat exchanger to provide all the building heating and cooling needs.  There are no boilers, chillers, or cooling towers necessary and therefore no maintenance cost that is associated with these components.  Indoor Air Quality (IAQ) is enhanced by a ventilation system that recovers energy from the exhaust air leaving the building. Carbon dioxide sensors assure that only the required ventilation air is brought in, further saving energy costs. Total energy savings calculated based on ASHRAE 90.1-2004 is 33.3%. The energy savings contributed 10 credits toward the LEED Gold certification and achieved a 7 out of 10 credits in the Energy and Atmosphere Credit 1 category.

The plumbing system maximizes water efficiency within the building to reduce the burden on municipal water supply and wastewater systems by use of low-flow fixtures. The facility is ADA accessible. There are sprinklers throughout the facility and thus fewer fire separations and dampers in the duct system are required.

An energy efficient lighting system was designed to use less than the wattage allowed by ASHRAE 90.1-2004. The lights are controlled by a combination of occupancy sensors and a programmable relay panel for automatic shut-off when spaces are not in use. Dual-level switching is also used.  Data network, VoIP phone system, central sound and sound reinforcement systems, video distribution system, security and CCTV systems are included in the design of this Ohio Facilities Commission funded project.
