JMT provided a comprehensive and innovative engineering approach to an HVAC upgrade project, including the first installation in Baltimore of new energy-efficient cooling equipment, for the Maryland State Highway Administration. The HVAC upgrades consolidated seven inefficient cooling systems within a 75,000 sf building complex into one efficient system that reduced energy use by 14%.  JMT also combined the boilers from multiple buildings into one common system, reducing the complex’s total carbon footprint. Significant pumping and piping modifications between the buildings were necessary to accommodate the changes to the chilled water and heating water systems.  Highlights included:

• Innovative chiller -- the first installed in the Baltimore area – which used a variable frequency drive to modulate the compressor output while minimizing the electrical usage associated with building cooling
• Building automation system to allow continuous monitoring of system performance and energy usage
• Eligible for certification under the LEED® Existing Building program
• Commissioning services during construction
• Construction phasing to accommodate the occupied site and buildings
