Elizabethtown Community and Technical College - Springfield Campus
Springfield, Kentucky
The new 52,000 square foot facility was built in 2009 to house administrative and faculty offices, lecture style classrooms, various lab spaces including machine tool and die labs, computer labs, an MTD computer lab, fluid power lab, motor controls lab, a basic electricity lab, and CEDC computer labs. Kerr-Greulich provided the fire protection, plumbing, mechanical, and electrical design.
Design features for the KCTCS campus building include:
NFPA 13 compliant fire sprinkler system throughout with semi-recessed chrome heads; all steel piping.
The backflow preventer is monitored by the building automation system in case there is a bypass event. Service crews can be dispatched to correct the problem and avoid damage to the facility and wasting of water. The system includes a compressed air system using compressor, distribution piping, and filtered drops to every lab work station.
Floor drains from the machine lab are routed to an oil separator with sophisticated monitoring to report status and excessive oil collection.
Emergency eyewash stations are located in each "wet" lab. These stations are monitored so that activation automatically initiates a call to a continuously-staffed emergency service provider.
Outside air is provided by two dedicated outside air systems using energy recovery and water source heat pump equipment. One system serves the machine lab and the other serves the rest of the building. Each system uses hot gas bypass to help with dehumidification.
The machine lab system is a variable air volume system. There is a welding fume exhaust system and the VAV system automatically adjusts air flows to maintain air pressurization and constant temperature.
The building uses small water source heat pumps for each classroom and teaching area. Outside air is distributed to each WSHP and air is demand-controlled using CO2 sensors.
All HVAC equipment is located in dedicated mechanical rooms so that service can occur without disturbing the classroom environment.
MDF/IDF communication rooms have dedicated/isolated HVAC systems that operate 24/7.
The building is equipped with a web-based building automation system (BAS) that is part of the overall KCTCS system. The building can be operated remotely and controls all HVAC system functions and certain lighting schedules.
The HVAC central plant includes a cooling tower with in-ground drain-down sump, and a heat exchanger to separate open and closed sides of the hydronic system. High-efficiency boilers provide supplemental heat for the hydronic system. All pumps are variable speed drive to match the output to the water flow demand.
High-efficient fluorescent lights are used throughout including all labs. Lighting is closely controlled via schedules. Occupancy sensing is performed in all spaces.
Critical lighting for the facility is connected to the emergency power system.
Main power includes a new 3000A 277/480 service, with additional spare circuits provided for future expansion and Isolated-ground power system for sensitive equipment. Buss way distribution is used in labs for flexible equipment arrangement.
100 KW 277/480 emergency power for critical operational equipment.
Green Design elements include:
Water saving toilets, electronic actuators throughout, and recirculated hot water system.
Energy recovery on outside air systems.
Building automation system is used to optimize energy use and minimize run time for HVAC systems and lighting.
Variable speed HVAC system to optimize performance relative to demand.
High efficiency lighting and maximum use of day-lighting.
