Tthreshold is the indoor cooling or heating setpoint [°C] in both the grid-on and grid-off scenarios. A similar metric, the Exceedance Degree-Hour, is recently developed by Salimi et al [4]. Instead of thresholding, this metric weights each hour by the distance from the current SET to the comfort zone [4]. @@ -182,10 +182,10 @@ N/A ## References ## -[1] S. Ayyagari, M. Gartman, and J.
