Claim 15:
16. A method for controlling temperature in an environment, comprising:
controlling the temperature in the environment using a heating, ventilation and air conditioning (HVAC) system;
generating an electrocardiogram (ECG) signal for an occupant of the environment;
generating environmental data selected from a group consisting of the environmental temperature, an ambient temperature, humidity, sun load and air velocity;
identifying inter-beat intervals based on the ECG signal;
controlling the HVAC system based on the inter-beat intervals and the environmental data;
generating N heart rate variability (HRV) parameters based on the inter-beat intervals, where N is an integer greater than one; and
using a comfort classification model defined in a N-dimensional HRV parameter space.
