Harshaw Trane Office Building and Trane Parts & DSO Building
Louisville, Kentucky


Trane is a leading global provider of both residential and commercial HVAC solutions which improve indoor environmental quality. Kerr-Greulich Engineers has worked with Harshaw Trane for the past two decades and we were pleased to be a part of the design team for their new LEED certified headquarters.

Highlights of the KGEI design include:
  • Kerr-Greulich provided a comprehensive life-cycle cost analysis for several HVAC systems. The owner wanted an unbiased evaluation with hard data and evidence to support the conclusions.
  • The life-cycle was extended to evaluate a low velocity duct system versus medium and high velocity comparing initial duct costs to increased fan horsepower in operating costs.
  • The system selected was a single duct, variable air volume system with energy recovery.
  • A central Building Automation System to control the environment, energy use, and lighting.
  • The support of this effort and the overall system selections are evidence of Harshaw Trane's commitment to sustainable design and the environment.
  • The Parts Center warehouse employs cross ventilation fans to increase occupant comfort during summer months.
  • Office areas in both buildings utilize roof mounted variable volume air handlers and variable air volume terminals to accommodate the load diversity in the spaces.
  • Energy management systems are used on both buildings to monitor and track energy use.
  • Low flow toilet fixtures.
  • Training room with gas, electric, and flue hook-ups for connection of equipment for demonstration and training.
  • Fully sprinkled per NFPA 13.
  • Incorporation of fire pumps to supply fire sprinkler system.
  • Compliance with IECC 2006.
  • Incorporated use of occupancy sensors or dual switching for lighting control based on space usage.
  • Incorporated use of time clock to "sweep off" interior lighting at unoccupied time with use of 2 hour over-ride switch for lighting during these unoccupied times.
  • 1200 amp electrical service.
