Reducing embodied carbon through mass timber design

We advanced the design of a nine-storey residential building that would deliver over 250 rental apartments in Washington, D.C.  

3300 Whitehaven will reposition a vacant, 1960s-era office building and potentially utilise a post-and-beam mass timber structure as a means of reducing the project’s overall embodied carbon footprint. By taking this approach, the structural system alone would eliminate up to 7,900 metric tonnes of carbon equivalent from the building’s carbon footprint, compared to buildings with conventional concrete structures.

Using mass timber will save foundation construction costs and we also anticipate that the biophilic design and higher ceilings will lead to significant rent premiums.

To further enhance its environmental impact and positioning, the project aspires to offer 100% electrification of residential unit appliances, integration of energy-efficient LED lighting and effective envelope design. 

3300 Whitehaven demonstrates how we are advancing sustainability through design and working to minimise carbon emissions across our portfolio. To that end, in 2023, our Investment team increased its GRESB score (an industry ESG assessment of real estate assets) by 12 points since our initial submission in 2021. Simultaneously, our Development team maintained its strong score of 91, surpassing the relevant benchmark average by 12 points.
