MacDill Air Force Base Critical Energy Solution

Two Million Square Feet of Mission Critical Energy Solutions

Tampa, Florida

Our retro-commissioning program of 89 facilities included offices, retail, gun range, warehouses, laboratories, lodging, dining, veterinary areas, and healthcare and childcare facilities.

Our design-build, turn-key implementation services included HVAC system upgrades to two mission critical facilities.

The new 80-ton, magnetic bearing, air-cooled chiller replacement can reach an energy savings estimate of 10 to 20 percent over original baseline building cooling energy usage and cost.

As part of the HVAC upgrades to the flight simulator, we removed two existing air-cooled chillers, six chilled water pumps, all existing chilled water piping, and the hydraulic room fan coil unit.

Enhanced part-load performance of the flight simulator's new HVAC system resulted in energy savings estimates of 12 to 18 percent.

All essential chilled water plant piping modifications and connections were fabricated on site with engineering support to ensure a seamless shutdown and rapid start-up of the completed cooling plant.

Both HVAC solutions included state-of-the-art high efficiency magnetic bearing air-cooled chillers and new control point integration to existing energy management systems.

When the MacDill Air Force Base's Reserve Headquarters chiller failed, the temporary cooling unit reached only minimal levels of occupant comfort. After demolishing the original chiller, we identified, procured, installed, and tested a new 80-ton replacement. In the flight simulator building, one of the chillers had failed and the other was on its last leg. If cooling was lost during any part of design, demolition, or installation, substantial damage to the simulator's computer system could have occurred. Our solution included two new chillers, two new variable primary pumps, new piping, a new hydraulic room fan coil unit, two new wall-mounted de-stratification fans, and replacement of the existing hydraulic air conditioning unit without interrupting cooling to mission critical rooms.

Our retro-commissioning program identified cost-effective energy-saving improvements to equipment maintenance and capital improvement projects across 89 buildings. Our energy-reducing strategies included duct static pressure setbacks, effective temperature resets, improved equipment scheduling, and effective ambient equipment lockouts. Equipment repairs and modifications included the replacement of control valves, actuators, and sensors along with control sensor calibration, HVAC diagnostics, and other routine preventative maintenance services.
