A new higher education facility is to be constructed in the Rocky Mountain Region, which will encompass a variety of spaces including learning, office, and lab areas. This new build on campus is set to push the boundaries of both the State and campus sustainability goals. The project has established ambitious carbon targets focused towards minimising both operating and embodied carbon, reflecting a broad commitment to sustainable and low-carbon building practices. The final decision to implement a mass timber system for the non-lab portions of the building stands as a defining moment for this project, marking a significant departure from conventional construction practices. The ability to precisely measure the environmental advantage over concrete was not just beneficial but essential. With Preoptima's advanced capability to calculate the carbon reduction potential of timber versus concrete, the evidence was clear and compelling, decisively guiding the choice for the final structural design. This strategic, data-driven decision underscores Preoptima's pivotal role in pioneering sustainable building practices.
