Designing for Sustainability - Reducing the Carbon Footprint with Embedded Carbon for Large Scale, Hybrid Timber Structures
Bush Bohlman was required to perform the structural analysis and timber design for the British Columbia Institute of Technology, (BCIT), student plaza, a pedestrian and public transport user gateway for the institute. The structure needed to establish a strong campus identity with a biophilic design and demonstrable support for sustainable building practices while ensuring structural safety according to local design codes. The hybrid mass timber structure consists of a Cross-Laminated Timber (CLT) canopy, CLT columns, and steel columns. By using S-TIMBER, the engineers were able to simulate the complex two-way bending behavior of the cantilevering roof panels and asymmetrical column layout. Having the model in S-TIMBER allowed for changes to be analyzed and re-designed, without the need to manually design individual timber and steel elements. S-TIMBER's design reports presented the design calculations concisely, yet transparently, for faster and easier reviews.

Leveraging Convergence to Build End-to-End Smart Ecosystems
Smart ecosystems span a variety of industries, technologies, and applications. They provide the backbone for operational innovation, efficiency, futureproofing, sustainability, and autonomy. Smart ecosystems harness the convergence of many technologies, and generally utilize data gathered from multiple sources to optimize operations, processes, systems, and products.
The evolving built-to-specs smart energy management ecosystem is a prime example of technology convergence – it maximizes artificial intelligence (AI), data analytics, and Internet of Things (IoT) technology create sustainable energy platforms. These smart platforms are more efficient when generating, distributing, and using energy, which brings them closer to net-zero emissions and reduces their environmental footprint.
