On the other hand, a review of the gas consumption data revealed that 50,000 kWh were used during January 2014, a 30 day period, which equaled 1,349 heating degree days based on a 60[degrees]F (15.6[degrees]C) outside temperature base (or 749 Celsius-based heating degree days).
Engine heat produces enough hot water to heat the facility's hangar despite being located in a region with over 5,000 heating degree days.
The HMS only effects the heating system's response to cold outdoor air temperature (heating degree days) while other building characteristics, such as the occupancy rate and thermal response, had minimal variations after the retrofit, so a two-parameter model using heating degree days was used:
There were only 24 population-weighted heating degree days last week compared with 64 at the same point last year.
