AIA Innovation Awards honor cutting-edge green-building solutions

"The team employed a number of mass timber solutions where steel, concrete, or framed systems would be traditionally called upon. The resulting 165,000-square-foot, five-story, high-performing building was delivered for less than $250 per square foot. Perhaps more importantly, a life cycle assessment has demonstrated that the timber’s carbon storage almost completely offsets the carbon impact generated by construction. [...] The innovative use of timber in the primary structure, lateral shear walls, and exterior walls required the design and build teams to collaborate closely to develop smart construction and installation solutions, chief among them prefabricated systems. The exterior walls were partially prefabricated off-site to allow for faster dry-in times and to reduce exterior trade coordination. Similarly, the ribbed floor panels and slat walls found in the lobby were also prefabricated in an effort to reduce field labor."

"A number of passive strategies were employed for the building, including rainwater capture, envelope design based on the Passive House Standard principles, and durable material application with a design life expectancy of 75 years. It is also topped with a significant solar photovoltaic array that will generate upward of 300,000 kilowatt-hours per year. Adjacent to the Catalyst Building, the Scott Morris Centre for Energy Innovation houses the centralized heating, cooling, and electrical systems for the Innovation District. This system includes solar panels, battery, and thermal storage, and is managed through a smart grid that allows for real-time, automated energy management, resulting in lower energy consumption and expense." ~ Click here to read more about this project.

BHoM Life Cycle Assessment Toolkit
Architect: Buro Happold

Project summary: "This valuable new tool, an open-source endeavor, is an accessible and data-driven framework that allows design professionals to measure embodied carbon of all elements within building design. Supported by a network of architects, engineers, and software developers who have contributed code to it, the Buildings and Habitats object Model (BHoM) boasts an impressive range of functionality that spans multiple disciplines and represents a transformative and democratic approach to measuring embodied carbon in everyday construction materials."

"Buro Happold launched BHoM as a data exchange network in 2016, seeking to build a stable framework for the code generated by architects and engineers across the world. Its initial goals were to create a way to share that code across the many platforms designers use every day, resulting in more than 60 adapters for different software and toolkits. Buro Happold released BHoM to the entire profession in 2018 and has continued to refine it further by collaborating with other open-source projects. Since then, the number of code contributors from both inside and outside the firm stands at 87."

"The tool was born out of a mission to quantify the environmental impact of materials in a transparent way with no payment barrier. This mission aligns perfectly with BHoM’s open-source origin, and, with that at its core, it allows users to access BIM data from Rhino or Revit; move that data into Grasshopper, Dynamo, or Excel; and ultimately export the results to visualization engines or databases for closer inspection."

"Free access to the tool allows users to take embodied carbon measurements at any point in the design process, facilitating better material selection. It leverages the significant experience of Buro Happold’s sustainability, structures, and MEP teams to include a full suite of datasets and environmental impact calculation methods. By opening it up to the entire profession, Buro Happold hopes to continue to improve its methods based on the input it receives." ~ Click here to read more about the project.
