The Relative Values of a Moisture Percentage in Building Envelopes: Moisture’s Spots with a Moisture Meter

There is a substantial lack of data relating to the hygrothermal traits of existing buildings and building materials. Moisture analysis in building envelopes is 1D (one-dimensional), 2D and 3D effects and feedback can be neglected. Many European standards treat a moisture percentage in building envelopes as surface and interstitial moisture condensation, such as BS EN ISO 10211, BS EN ISO 13788, BS EN ISO 15148, and BS EN 15026. In this manuscript, there was a tendency to capture a relative quantity of superficial moisture, by metering spots on the inner and outer surface of wall lining systems with a moisture meter. The metering specimens were the buildings with different envelopes: a wooden hut-house, a masonry building and a building partially sheeted in stone. The referent heights on wall linings, for taking the moisture data were specified as 50 cm for a wooden and masonry building and 80 cm for a stone-sheeted building, from the ground. The several conclusions were brought. The buidling’s envelope is much influenced by the weather. The outer material surface in a shadow can possess a slight moisture quantity. One of the recommendable issues, originating from this manuscript is to abolish or reduce the buildings’ vulnerability to climate fluctuations immediately at the beginning of construction.
