About the Client

The historic DuPont Building has been a landmark in downtown Wilmington since 1908. The longtime headquarters for the DuPont Company, the 1,000,000 square foot building was purchased by The Buccini/Pollin Group (BPG) in 2017 to convert into a mixed-use facility consisting of a hotel, luxury apartments, a theater, retail, and offices.

BPG partnered with Seiberlich Trane Energy Services to modernize the facility’s infrastructure and improve tenant comfort. The project leveraged Commercial Property Assessed Clean Energy (C-PACE) financing, the first project to do so in the state of Delaware.

Project Objectives

  • Reduction in utility spends
  • Modernize building with new HVAC equipment
  • Increase tenant comfort level

Energy Conservation Measures Installed

  • New high-efficiency centfigual chillers
  • New chiller plant automation system
  • Cooling tower refurbishment & system upgrades
  • Convert chilled water pumps to variable flow
  • New timing switches on steam system
  • Boiler system insulation
  • Smart exhaust control system on kitchen hoods
  • Automated individual tenant submetering
  • Transition to low GWP refrigerants

Energy Savings Results

A big feature of the modernization was replacing three 60 year old chillers with new Trane high-efficiency centrifugal chillers using low Global Warming Potential (GWP) refrigerants. The upgrades will save the property owner an estimated $14.2 million over the lifespan of the equipment and reduce emissions by 8,190 metric tons of CO2 equivalent annually.
