Thermal Comfort Ranges

In most places temperature set points are not set by local regulations. They are not in the US.  Expanding temperature set points as a strategy also requires additional attention to the other aspects of our thermal comfort like radiant temps, airflows, etc. We have a school client that has a winter set point of 65F and summer of 80F. However the building is superinsulated and there are ceiling fans and natural ventilation strategies which allow for comfort within an expanded range. The Rocky Mountain Institute has done a great deal of application on this issue - https://rmi.org/our-work/buildings/scaling-zero-net-carbon/rmi-innovation-center/thermal-comfort/  So your project could provide an opportunity to challenge the assumptions behind the local regulations.
