Assessment of Potential Techniques for in-Situ, Real Time Moisture Measurements in Building Envelope Systems: A Literature Survey

摘要

The important role which moisture plays in building envelope system performance creates a need for instrumentation capable of measuring moisture content under dynamic environmental conditions. In this survey information was compiled on the (1) range of moisture contents to be expected in various building materials, (2) moisture contents encountered in building envelopes under different field conditions, and (3) techniques available for measurement of moisture in solid materials and humidity in the atmosphere. An assessment was made of the ability of these techniques to accurately measure moisture content and humidity in components of the building envelope. Recommendations as to candidate techniques for further development and evaluation are given. (ERA citation 09:018694)
