Building ventilation eats 10% of all US energy — just for temperature. Most systems are on autopilot. Dr. Suresh Dhaniyala (Clarkson University, sensors on the International Space Station) explains how sensor-driven ventilation cuts energy 30-40% while improving the air we breathe. If your work touches buildings, facilities, or public health, your job can be a climate job.

In this episode, we cover:

• Why CO2, humidity, and particulates matter more than temperature alone
• The 10% stat: what's really consuming building energy, and where the savings hide
• How smart ventilation delivers better air quality AND lower energy use
• The 30-40% energy savings that's already been validated
• Who can start now: facilities managers, VPs of operations, building engineers
• Three sensors that matter: particulate matter, VOCs, CO2
• How NASA monitors air on the International Space Station
• Practical first steps: EPA AQI, indoor sensors, raising the question with your team

Who this episode is for:

• Facilities managers, VPs of Operations, building engineers
• HVAC and public health professionals
• Parents concerned about indoor air quality in schools
• Anyone whose work touches buildings
