3300 Whitehaven: ESG

Currently in design, 3300 Whitehaven is a nine-storey residential building in the historic Georgetown neighbourhood of Washington, D.C. The project will reposition a vacant, 1960s-era office building into over 250 rental apartments, with the potential to utilize a post-and-beam mass timber structure as a means of reducing the project’s overall embodied carbon footprint.

In addition to pursuing the use of mass timber, 3300 Whitehaven will strive to reduce its operational carbon impact through 100% electrification of residential unit appliances, LED lighting, and efficient envelope design.

Environmental highlights

Mass Timber

  • Structural system alone would eliminate up to 1,500 metric tonnes of carbon equivalent, as compared to buildings with a more typical concrete structure
  • Potential to serve a critical leading-edge function to help pioneer important construction technology within the commercial real estate development industry in the United States and globally
  • Introduces a unique, stress-reducing biophilic design element into residents’ physical surroundings

Energy

  • 100% electric residential unit appliances, LED lighting, and efficient envelope design
  • 30%+ reduction to site energy use intensity as compared to industry benchmarks

Water

  • Targeting a 30% reduction in potable water usage

Landscape

  • 20,000 square feet of vegetated green roof reduces solar heat gain in addition to providing residents an additional biophilic experience
  • 18,000 square feet of thoughtfully-designed play area for the adjacent school
  • Landscaping comprises more than 11,000 square feet of native plant species that further reduce water consumption, are more naturally pest and climate resilient, and prevent storm water run-off

Transit Oriented Development

  • Located within a 3-minute walk of three higher frequency bus routes, including the D.C. Circulator
  • Three grocery stores within a 10-minute walk from the site
  • 15% reduction in the number of parking spaces currently provided on site encouraging the use of alternate modes of transit
  • 100+ bicycle parking spaces
