VANCOUVER—DIALOG recently announced it has officially filed for a patent on its Hybrid Timber Floor System, an architectural design concept named the winner of Fast Company’s 2021 World Changing Ideas awards competition earlier this year.
The system combines cross-laminated timber panels with steel and concrete for use in the construction of highrise towers with a significantly reduced carbon footprint, stated a recent release. Once approved, the system could lead to the introduction of mass timber structural systems into the supertall tower category. And when incorporated with other green building technologies, towers as tall as 100 storeys could achieve carbon neutrality, DIALOG says.
With post-tensioned steel cables encased in concrete bands and embedded into Cross Laminated Timber (CLT) panels, DIALOG’s hybrid system will allow for a 12-metre column-free span, whereas standard CLT design systems currently span three-quarters of that distance. The patents have been filed by the international design firm in Canada, the United States, the European Union, Australia and China.
“Floor plates typically comprise approximately 70 per cent of building material utilized in highrise towers. By focusing our talents and resources on creating more innovative floor plate solutions like this one, we believe that we can make a major dent in the environmental footprint of the built environment in the not-so-distant future,” said Craig Applegath, a founding partner at DIALOG, in a statement.
