Comfort in Buildings, and Vehicles Too

The emerging trend toward smart electric vehicles is creating new opportunities for synergistic innovations that are applicable to both buildings and cars. For example, the Tesla Powerwall, which grew out of automobile battery development, now offers a way for buildings to be more grid responsive. Likewise, model-based control concepts, greatly advanced by the automotive sector, are now being tested in the control of complex commercial buildings. These synergies, what we might call the building-automotive nexus, are also reflected in CBE’s body of research on thermal comfort.  Read more

CBE’s “Changing the Rules” Demonstrates an Occupant-Based Paradigm for HVAC Control for Energy Savings and Improved Thermal Comfort

CBE’s research team recently completed an ambitious project with complementary goals of making buildings occupant-responsive in real time, and addressing outdated rules-of-thumb that were leading to poor performance in both energy use and occupant comfort. Among the numerous findings from this work, it demonstrated that “personal comfort” chairs led to comfort satisfaction for 96 percent of the test subjects, a level well above what is observed in most buildings. The project team also developed and tested innovative HVAC control methods offering significant energy saving potential, and that may be easily implemented in commercial buildings using the most common overhead variable-air-volume (VAV) reheat systems.
