WWU's Kaiser Borsari Hall Is First US STEM Building With ILFI Zero Energy and Zero Carbon Certification

Western Washington University's Kaiser Borsari Hall has become the first higher education STEM building in the United States to earn both Zero Energy and Zero Carbon certification from the International Living Future Institute. The building, which opened in January 2025, also marks the first state-funded Washington project to use ILFI certification as an approved alternative to the LEED Silver standard required by state law. In its first full year, the building posted a measured site Energy Use Intensity of 33.4 kBtu per square foot, more than 80% below a code-minimum lab. An 82 kW rooftop solar array generated over 83,000 kWh, and a mass timber structure helped cut embodied carbon by 70% through documented reductions and verified offsets. The 12-month third party audit behind the certifications is what separates this from design-stage green building claims. The project's approval as an ILFI alternative to LEED could give other Washington public agencies a clearer path to performance-based certification. For anyone tracking low-carbon buildings, the useful details are the measured EUI, the solar generation, and the embodied carbon reduction method, not just the plaque.

Good to see a state-funded building prove out ILFI's performance standard instead of just checking LEED boxes. The 12 month metered audit is the part that matters. Anyone know if the embodied carbon offsets were third party verified or just self reported?

The 33.4 EUI number is the real headline. Labs usually eat energy, so 80% below code-minimum is strong. Curious how the VRF and heat recovery hold up over a few more years, especially with the marine west coast climate.

82 kW array covering 75% of roof and only offsetting up to 35% of monthly peak use. That shows how hard zero energy is for a lab building. Would like to see the seasonal breakdown, because winter heating with air source heat pumps in Bellingham is not trivial.

First STEM building in the US with both ILFI zero energy and zero carbon. Also first state funded Washington building to use ILFI instead of LEED Silver. That precedent might matter more than the building itself.

State law required LEED Silver, so the project had to get ILFI recognized as an equivalent. That is a real policy change, not just a plaque. Other Washington agencies can now follow the same path. Worth watching whether the state updates the standard for all public buildings.

Mass timber gets credit for the embodied carbon cut, but the operational numbers come from heat recovery, VRF, and a tight envelope. Those are all repeatable on normal projects. Would like to see cost premiums versus a standard lab, because that decides whether other universities copy it.
