This four story facility is 50 years old and while it is not on the Historical Register, it is considered architecturally significant. The project required all exterior modifications to be coordinated with the State of New Mexico, and all of the mechanical systems were replaced while the facility was occupied and in service. An asbestos abatement project, worn out systems and changes in building function/usage required modifications to the patient rooms, kitchen, penthouse area, and roof.
The Mechanical design landed on an earth-coupled water source heat pump with 210 bore holes (4 inch diameter, 200 feet deep each) installed below the existing parking lot. Conditions were found to be ideal for economic drilling and for and excellent earth loop heat transfer performance. This design created considerable positive energy conservation in both heating and cooling modes.
The exterior work, which included the bore holes, underground heat pump piping, mechanical building, make-up air assembly, circulating pumps assembly, mechanical shaft to all four floors, make-up air ductwork installed in the shaft and electrical in the shaft, was completed while the existing system operated with a seamless transition to the new system.
