GLHN is discussing the incorporation of innovative design standards with the University of Arizona to align with the USGBC’s new LEED v5 framework. The focus is on using the enhanced energy efficiency prerequisites in LEED v5 to significantly reduce operational energy consumption and lower operations and maintenance costs for the university. Compared to LEED v4, which primarily emphasized energy cost savings, LEED v5 shifts the focus towards carbon emissions reduction as the primary metric for energy performance, advancing its approach to sustainable design.
The university can meet and exceed the expectations of sustainable building practices by targeting carbon emissions through operational and embodied carbon reduction strategies. These strategies include optimizing building enclosures, integrating HVAC and lighting system controls, and utilizing renewable energy and electrification.
The next step is to meet with the University of Arizona’s Office of Sustainability, Planning, Design & Construction, and Facility Services. The goal is to incorporate new approaches to responsible design in the University’s Design and Sustainability Standards. This will require a comprehensive design analysis, site energy estimate, carbon projection review, and a detailed decarbonization plan.
By performing these assessments early in the design process, opportunities can be identified to reduce peak thermal loads, enhance water efficiency, and incorporate electrification strategies that minimize reliance on fossil fuels, contributing to lower operational expenses and long-term sustainability. These measures and the emphasis on electrification and reducing peak thermal loads differentiate LEED v5 from its predecessor and represent an advancement in achieving energy efficiency and lowering maintenance costs for the University of Arizona.
