Nicola,<br>
The capacitance is the mass times the specific heat. Typically a good
first guess for a room is to multiply the volume of the room by 1.2
kg/m3 (to get the mass of the air) and then to multiply that value by
somewhere between 5 and 10. You are essentially saying that the air and
furnishings have a capacitance that is 5 to 10 times as much as the
capacitance of the air itself.<br>
Kind regards,<br>
