  2. Balance point temperature - Wikipedia

    en.wikipedia.org/wiki/Balance_point_temperature

    The building balance point temperature is the outdoor air temperature when the heat gains of the building are equal to the heat losses. [1] Internal heat sources due to electric lighting, mechanical equipment, body heat, and solar radiation may offset the need for additional heating although the outdoor temperature may be below the thermostat set-point temperature.

    Mechanical floors are generally counted in the building's floor numbering (this is required by some building codes) but are accessed only by service elevators. Some zoning regulations exclude mechanical floors from a building's maximum area calculation, permitting a significant increase in building sizes; this is the case in New York City. [1]

  6. Thermal efficiency - Wikipedia

    Gross heating value accounts for water in the exhaust leaving as vapor, and includes liquid water in the fuel prior to combustion. This value is important for fuels like wood or coal, which will usually contain some amount of water prior to burning. Which definition of heating value is being used significantly affects any quoted efficiency.
