CO2 sensors are used in heating, ventilation, and air conditioning systems to improve air quality and energy efficiency.

Futurists have a poor track record when it comes to actually predicting the future. An aerocar in every garage, jet back-packs, and free, unlimited nuclear power were all promised to us in an exciting, clean future. Yet, 50 years later, we’re still waiting for each of them to arrive. The same goes for houses. In the early part of the century, Buckminster Fuller created the Dymaxion house, which was updated and sat on top of a pylon for the Jetsen cartoon family. While we were excited about the idea of cheap, factory-made houses, when it was time to purchase them,...

The LEED standard recognizes the usefulness of CO2 to monitor Indoor Air Quality. But did you know that the LEED standard for new construction includes provisions for measuring CO2 levels outdoors? EQ1.2 – Outdoor Air Delivery Monitoring, a possible credit in the United States Green Building Council’s LEED Certification for New Construction, calls for either carbon dioxide monitors or outdoor airflow monitors that signal when fresh air is needed. Depending on the configuration of the HVAC system, outdoor CO2 measurements can be used to provide a baseline for indoor air quality. While ambient outdoor air was historically considered 400ppm, the...
