Client: Santa Ana Pueblo
Location: Santa Ana, New Mexico
Lopez Engineering, Inc. (LEI) was sub-contracted through ArSed Engineering to provide electrical design services for the Santa Ana Multipurpose Building in Santa Ana Pueblo, New Mexico.
The project design was separated into three phases: Phase X – Baseball Fields, Phase Y – Wellness Building and Phase Z – Education/Performing Arts Building. LEI completed Phase Y – Wellness Building, which was designed to LEED silver.
The Wellness Building is a 64,000 ft2 building that houses a pool, two basketball courts, an exercise room, a recreational room, offices, child-care area, a commercial kitchen, a demonstration residential kitchen area, a banquet room, and support areas. The second floor consists of offices and an exercise area.
The electrical system service entrance switchboard is 480Y/277V, 3-phase, 4-wire, 1600 amp, 42 KAIC. The remaining electrical distribution system consists of 480 volt and 208 volt panelboards as well as dry type transformers. An optional 250kW photovoltaic (PV) array on the building roof that would have provided approximately 40% of the buildings total estimated load was pursued but not implemented due to limited funds. Heating and cooling were provided by a ground source heat pump system. Variable Frequency Drives (VFD) controlled by a controller were provided for the pool pumps, which consisted of one 30HP, one 40HP, and one 50HP pumps. The elevator was served at 480 volts.
Interior lighting, at 277V, was provided in accordance with IESNA recommendations with occupancy sensor control. Basketball court lighting utilized pendant mount 2’ X 4’ fluorescent fixtures with T5 HO lamps, and wire guards mounted at 26 feet. Pool lighting, pendant mounted at 25 feet, used indirect 2’ X 4’ fluorescent fixtures that were both corrosion resistant and weatherproof, which fixtures were designed especially for pools. This area’s lighting was originally designed using light tubes for easy maintenance but it was rejected as being too expensive. Office lighting consists of 2’ X 4’ recessed fluorescent troffers with T-8 lamps and electronic ballasts. Parking lot and court yard lighting, provided from pole mounted fixtures with High Pressure Sodium lamps, are designed to be photocell on, time clock off. Special systems included telephone/data and fire alarm systems.
The project was designed to LEED silver but did not include documentation or certification.
