Moisture monitoring system for buildings
First Claim
1. A method of monitoring moisture in a building comprising:
- providing a plurality of moisture detectors, each having a detector parameter with a range of values ranging from a dry value in the absence of moisture and different wet values in the presence of moisture depending on the quantity of moisture;
dividing the building into a plurality of zones;
providing a plurality of sensor units each associated with a respective one of said zones;
locating the moisture detectors such that each zone contains at least one of the moisture detectors;
connecting each sensor unit to said at least one moisture detector in the respective zone;
providing a common monitoring unit for cooperation with a plurality of the sensor units;
each of the sensor units providing the value of the detector parameters of the at least one moisture unit connected thereto;
and performing a risk assessment calculation of potential damage for at least a part of the building using the wet values from the moisture detectors for the sensor zones in said at least a part;
wherein the risk assessment calculation is effected using the different wet values from a plurality of the moisture detectors in conjunction with at least one additional factor indicative of potential damage to the part of the building;
and wherein the risk assessment calculation includes as input data therein the wet values and as a first additional factor a value which is indicative of a total area of the moisture as provided by the number of sensor zones that are responding with a wet value and as a second additional value the number of consecutive time periods that the sensor zone has reported wet values.

Abstract
A method of monitoring moisture in a building is carried out using moisture detectors, which provide an output resistance value ranging from a dry value in the absence of moisture and different wet values in the presence of moisture depending on the quantity of moisture. Rather than emit an alarm based solely on a moisture threshold, a risk assessment of potential damage is calculated for at least a part of the building using the wet values from the moisture detectors for the sensor zones using as input data the wet values and as a first additional factor a value which is indicative of a total area of the moisture as provided by the number of sensor zones that are responding with a wet value and as a second additional value the number of consecutive time periods that the sensor zone has reported wet value. The calculation can use computer modeling to calculate a risk factor for growth of mold or a risk factor for growth of timber decay fungi.

9. A method of monitoring moisture in a building comprising:
-
providing a plurality of moisture detectors, each having a detector parameter with a range of values ranging from a dry value in the absence of moisture and different wet values in the presence of moisture depending on the quantity of moisture; dividing the building into a plurality of zones; providing a plurality of sensor units each associated with a respective one of said zones; locating the moisture detectors such that each zone contains at least one of the moisture detectors; connecting each sensor unit to said at least one moisture detector in the respective zone; providing a common monitoring unit for cooperation with a plurality of the sensor units; each of the sensor units providing the value of the detector parameters of the at least one moisture unit connected thereto; and performing a risk assessment calculation of potential damage for at least a part of the building using the wet values from the moisture detectors for the sensor zones in said at least a part; wherein the risk assessment calculation is calculated using the following formula; where REL is the potential average accumulated over all zones in an elevation, m is the number days, n is the total number of zones in the evaluation, LRk(i) derived from building science modeling for mold and/or timber decay fungi growth, is the potential the growth of mold on the ith day as a function of the average moisture content obtained from the values of the moisture detectors and temperature during the day. - View Dependent Claims (13, 14, 15, 16, 17)
