E-Energy2014Hot, Cold and In Between: Enabling Fine-Grained
Environmental Control in Homes for Efficiency and
HVAC energy efficiencyBecause they do not have fine-grained control for multiple rooms, residential HVAC systems often spend a lot of energy to condition unoccupied areas of the home. So they augment sensors (temp sensors, booster fans, space heaters, power strips, server-side control software ). By heating and cooling different rooms to different setpoints at different times, one can leverage one's understanding about the way spaces in the home are actually used in order to
fine-tune the environmental settings
E-Energy2014An occupant-participatory approach for thermal comfort enhancement and energy conservation in buildingsHVAC comfort improvementTo minimize complaints, the current practice of the facility management is to adopt very conservative temperatures, leading to massive waste of energy. In this paper, we actively take thermal comfort into consideration. We propose a participatory approach allowing the occupants provide feedback regarding their comfort levels. A major challenge for a participatory design is to reduce intrusiveness of the system. To this end, we develop a temperature comfort correlation model that can build a profile for each occupant. The decision of setpoint temperature can be primarily model-driven, requiring minimal inputs of the occupants. Get occupant comfort input through cell phones.
