Abstract

The paper outlines a derivation of a fundamental equation of humidity for any enclosed space or set of spaces exchanging air with each other and with the external environment. The solution enables the humidity levels to be predicted for any arbitrarily changing set of conditions. A number of simpler solutions for room humidity levels are given and discussed. A program to allow users to evaluate different hypothetical effects in the general case easily is cited. A brief discussion, using some specific examples, is made of the various factors contributing to the resultant room humidity and the effectiveness of ventilation. The analytical form of the solution given to the equations allows a user to assemble a model of the humidity response of a building to any degree of complexity using simple calculations.
