21 Dupont Circle – Borger Property Management Portfolio

Baumann Consulting provided energy efficiency services including an ASHRAE Level 1 + 2 Energy Audit for 21 Dupont Circle, an 8-story office building in Washington, DC, to identify and implement measures to reduce energy usage and comply with DC's BEPS.

Built-in 1971, 21 Dupont Circle is a 75,602 8-story office building located in Washington, DC. The building is part of a portfolio of buildings in DC and the metropolitan area managed by Borger Property Management.

21 Dupont Circle uses energy in ways typical to office buildings including heating, cooling, ventilation, lighting, plug loads, and domestic hot water. The building’s energy sources are natural gas to generate hot water for heating and domestic water use and electricity for the rest of the building. Chilled water for space cooling is provided by a central chiller. More than 75% of the energy used by the building is for space conditioning and ventilation. Borger Property Management hired Baumann to help identify opportunities for 21 Dupont Circle to reduce its energy use in response to DC’s Building Energy Performance Standard (BEPS).

Baumann recently completed an ASHRAE Level 1 and 2 energy audit and identified several measures that can help achieve a 35-40% reduction in energy consumption. Some of those measures include:

  • Upgrading the central plant systems- boilers, chillers, and air handling unit
  • Upgrading the building envelope with high-performance window solutions
  • Retro-commissioning and rebalancing the mechanical systems
  • Installing a solar-PV system
