Map It!

Located in south-central New Mexico, the Alamogordo Public School District (APS) stands at an elevation of 4,350 feet above sea level and serves a population of 40,000 with 6,300 students. Originally built in 1961, Chaparral Middle School houses more than 126,800 square feet of space and serves more than 660 students.

 

In 2005, APS performed a lighting retrofit, which replaced T12 fluorescents with efficient T8 lamps and electronic ballasts. This upgrade was part of a performance contract with Energy Control Inc. (ECI), which serves as the District?s energy service company. The performance contract included direct digital control (DDC) in four schools, a ground-source heat pump system (GHP) at one school, and lighting retrofits in 13 schools - delivering $198,000 in annual savings. Since the initial GHP system, APS has converted an additional 5 schools, Chaparral being among them. GHP systems now provide temperature control for more than 50 percent of the District?s educational space.

 

The 2005 lighting retrofit created a 16 percent improvement in electricity consumption at Chaparral. In 2009, APS started a targeted energy program to manage start/stop times for the building automation systems. The result was an additional 23 percent improvement in electric consumption. EPA?s ENERGY STAR program provided benchmarking analysis through Portfolio Manager, EPA?s ENERGY STAR measurement and tracking tool. APS is able to gage the effectiveness of their energy measures and compare the results against similar facilities.

 

In 2011, ECI completed a full-scale electrical and mechanical retrofit encompassing heating, ventilating, and air conditioning (HVAC) control equipment. The school gym used rooftop evaporative swamp coolers and unit heaters for the locker rooms. The coolers were controlled manually with on/off switches. The project converted evaporative coolers and wall-mounted gas furnaces to ground-coupled heat pumps. ECI provided design/build services to size a bore field with 140 bore holes and to install 57 heat pumps for individual classroom control, delivering 196 tons of cooling capacity. DDCs provide system optimization and integration into the District?s Ethernet local area network. The installation also included current code ventilation upgrades using energy recovery ventilation units, which enhance the system's efficiency, variable speed drives for the ground source main pumping system, and electrical system upgrades.

 

Chaparral Middle School has seen a 49 percent improvement in natural gas consumption after the GHP system installation. The building team also realized operational and maintenance savings by removing mechanical systems that were beyond their useful life and had excessive maintenance requirements. At Chaparral Middle School, GHP systems simplify maintenance and operation requirements.
