In a word... Energy.
Why Timber?
It is clear that we aren’t meeting the IPCC goals as the end of 2020 draws near, and this fact paired with the rapidly increasing demand for construction paints an ugly picture. Is there a way we can reverse the ongoing trend and create a more sustainable construction industry?
Energy Use in Construction.

Construction as a carbon sink.
The building infrastructure we construct stands for many decades, and the sheer quantity of buildings we will need to produce between now and 2050 is a tremendous opportunity to trap carbon. Current construction culture favours steel and concrete, which require massive quantities of energy and resources to produce. Traditional lightweight timber systems cannot match steel and concrete in meeting the demands that modern society has for its structures. Massive timber is the only material that is both renewable and can meet the demands that modern society has of its structures. Massive timber, AKA mass timber or engineered timber, is an umbrella term encompassing a range of value-added timber products created in a factory setting by recompositing solid-sawn timber boards into required forms – unrestricted by the dimensions of boards sourced from any individual tree. The collaboration of mass timber construction, which sequesters up to 1 tonne of carbon per cubic metre of material, and high-performance building standards such as Passive House, presents a real possibility of true zero energy buildings.

Beyond Environment
Scaling to the Future
Mass Timber and Prefabrication
So how exactly will we build a New York City’s worth of massive timber, high performance buildings per month for the next 40 years?
Prefabrication.
The strongest economic case for building with mass timber is its disposition in favor of prefabrication and offsite manufacturing. Baked into its method of manufacture, individual boards, panels, beams and columns are composited to tight tolerances, cut to angle, fit with dowels, covered with insulation, fire protection, or finishes, and transported to site where they can be rapidly assembled into the final product. This change in building method challenges the current culture of construction: to be ready for manufacture, the design needs to be completely resolved. This requires a high level of coordination between project teams, and a rigorous approach to building information modelling. We are witnessing a shift in the construction industry with the uptake of these methods, and a cultural shift that is heralding a future of highly efficient, prefabricated, sustainable and high performing buildings.
The way we handle our energy remains the key to our prosperity. Over the coming decades it is clear that we will need to find ways of doing much, much more with much, much less. For the construction industry, this represents a grand opportunity to reinvent our infrastructure and scale to the future. By harnessing prefabrication and bringing low embodied energy materials in structures of low operational demand, we can build beautiful, net-zero energy buildings as a platform for our civilisation to thrive.
That is why we choose to design in timber.
