GlaxoSmithKline’s office building was designed to be an innovative green building that brings together a wood structure, high energy efficiency and an optimal work environment. This two-storey, 2,700-m2 office and commercial building is capped by an asymmetrical curving roof.

The main façade boasts a fully glazed, double-skinned envelope that allows sunlight to flood a spacious atrium in which wood is omnipresent. The structural framework is a complex assembly of FSC-certified glulam beams and columns. For the first time in Quebec, glulam columns of varying diameter were used. Along the façades, cylindrical columns form A’s and X’s, while in the centre of the atrium, the columns attain the impressive dimensions of 184 x 502 mm. High up in the atrium, an exposed three-dimensional truss is formed out of 13 intersecting cylindrical pieces. One of the connections brings together eight pieces at the same point. The system as a whole supports a set of rectangular beams (137 x 457 mm) that have been curved twice to produce the roof’s winding form. In addition to the structural framework, the floor and ceiling are made out of exposed glulam decking and engineered wood flooring.

Altogether, more than 500 m3 of engineered wood was used, thus helping to sequester 460 tons of CO2. Credits were purchased on the international carbon market, thus allowing the project to achieve carbon neutrality. The use of best bioclimatic architecture practices also meant that the energy expenditure could be cut 55% in comparison with a reference building. Ultimately, this structure should qualify for LEED-Gold certification.

The total budget for the project was $11.2 million.
