A study of building envelope and thermal mass requirements for achieving thermal autonomy in an office building

A room is not heated by increasing its internal energy but by decreasing its entropy due to the fact that during heating, the volume and pressure remain constant and air is expelled. We first present a simple solution treating the air in the room as an ideal gas. We calculate the differential entropy change and heat transfer and give numbers for a typical room including estimates of heat loss through windows and walls. We also demonstrate the power of thermodynamics to derive the entropy and internal energy changes for any gas.

The homeostasis solution – Mechanical homeostasis in architecturally homeostatic buildings

The illustrious question by German Astrophysicist R. Emden, “Why do we have winter heating?” has been re-examined for air following both the ideal and imperfect gas laws; the internal energy of the...

Whether or not the total energy content of the air increases or decreases cannot be answered unambiguously.
