If you work in a lab, one small habit can save a surprising amount of energy: Shut the sash.

Architect Jacob Werner explains why airflow, safety, and infrastructure choices are some of the biggest (hidden) climate levers.

This episode is part of Any Job Can Be a Climate Job — a podcast exploring how people bring climate impact into everyday work, even in roles that aren’t labeled “climate.”

Research labs are where some of the most important work in the world happens: curing disease, developing renewable energy, and building the future of science.

They’re also some of the most energy- and resource-intensive buildings we have. Not because people are careless, but because labs are designed to optimize for safety, airflow, and precision.

In this episode, I talk with Jacob Werner, an architect at Ellenzweig who designs science labs for colleges and universities, about why labs function more like machines than offices — and why that makes design such a powerful climate lever.

Jacob explains how decisions about airflow, temperature control, filtration, and safety systems quietly shape energy use for decades — and how good design can make the sustainable choice the easiest choice, without relying on constant heroics from the people inside the building.

Listen for:

• Why labs use so much energy (and what “stable experimental conditions” requires)
• What designers can “bake in” so sustainable behavior is easier (fume hood sashes, recycling access, efficient HVAC)
• How sustainability sticks best when it’s treated as good design, not an add-on
• Practical lab actions that matter: Shut the Sash, lights, and equipment power-down norms
• Why climate action often starts far upstream, in systems most of us never see
