building

Located in south-central New Mexico, the Alamogordo Public School District (APS) serves a population of 40,000 with 6,300 students and stands at an elevation of 4,350 feet above sea level. The 56,466-square-foot Yucca Elementary was originally built in 1966 and serves 550 students. Prior to its efficiency efforts, the school used refrigerated cooling, which is very inefficient in a high desert climate because high desert temperatures can cause excessive heating and cooling loads on mechanical equipment. 

 

In 2005, the district's energy service company (ESCO), Energy Control Inc. (ECI), completed a full scale electrical and mechanical retrofit including heating, ventilating, and air conditioning (HVAC) control equipment and a lighting retrofit, which replaced T12 fluorescents with efficient T8 lamps and electronic ballasts.  Many systems were non-functional and providing little to no control. A direct digital control (DDC) system was installed to provide classroom control and tie into the district LAN for extended operability and measurement and verification, while allowing interoperability with legacy controls. The DDC system provides individual classroom control for a high level of student/teacher comfort. ECI performs operation and maintenance services to ensure the system is operating efficiently, meeting savings goals, and receiving proper maintenance. 

 

In 2006, a bore field and ground-source or geothermal heat pump (GHP) system were installed for temperature control. The GHP system incorporates water-source heat pumps designed with larger condensers to accommodate for wider temperature swings on the ground loop, as well as higher efficiency compressors. The cafeteria evaporative cooler was replaced with a 20-ton unit. Larger motors were installed for control of the portable buildings. The retrofit created additional load but succeeded in providing a comfortable environment. The efficiency of the system has allowed for an acceptable cost per square foot even with the increased load. Energy recovery ventilators were installed to enhance the system's efficiency. 

 

Yucca Elementary School saw an increase in electrical consumption but a 66-percent drop in natural gas consumption. The building team also experienced operational and maintenance savings by removing mechanical systems that were beyond their useful life and had excessive maintenance requirements. GHP systems simplify maintenance and operation requirements. In 2007, additional GHPs were put in place for complete renewable energy temperature control of the school. The completion of the GHP system dropped gas consumption by 70 percent from the baseline overall.

 

ENERGY STAR provides benchmarking analysis and measurement and verification of the energy initiatives. The school applied for and was awarded the ENERGY STAR for superior energy performance in 2010.
