Western Washington University's Kaiser Borsari Hall in Bellingham has earned Zero Energy and Zero Carbon certification from the International Living Future Institute. The 53,345-square-foot mass timber STEM building was verified using a year of operational data, not just design projections. It uses all-electric HVAC, rooftop solar on 75% of the roof, and avoids natural gas entirely, cutting lab energy use by more than 80% compared to a typical lab benchmark. The project also cut embodied carbon by 79% through mass timber construction and eliminated a planned basement, saving over $2 million and 226 tons of embodied carbon. With an EUI of 33.58 kBtu/sf/year versus 168 for a typical lab, the building shows how early design choices can reduce both cost and emissions. It now serves as a living laboratory for students in engineering and energy studies.

Good example of a green building story that doesn't stop at design promises. WWU's Kaiser Borsari Hall got Living Future certification based on actual operating data, which is rare. Mass timber, all-electric HVAC, no gas hookup, and 75% roof solar. Worth a read if you track zero-carbon buildings.

One thing to watch: net-zero here depends on buying renewable energy from Puget Sound Energy for what the roof doesn't produce. That's fine, but it's not the same as full on-site storage. The building has future battery hookups, not batteries yet. Curious how the winter load shapes up in Bellingham.

Certification based on measured performance, not modeled estimates, is the right way to do this. Also notable that eliminating the basement and reusing adjacent space cut capital cost and carbon at the same time. More projects should treat carbon targets as preconstruction decisions instead of bolt-on features.

The numbers that stand out to me: 79% embodied carbon cut from mass timber, EUI of 33.6 vs 168 for typical labs, and $2M saved by dropping the basement. That last one is the kind of decision that usually gets killed early. Good to see it documented.

Nice to see a public university building get dual zero-energy and zero-carbon certification. The lab energy reduction over 80% is the part that matters most, since labs are energy hogs. If this holds up in operation, it's a useful template for other STEM buildings.
