Simple Questions. These can all be answered by looking at the graph on the website without any further calculation:
How much moisture is in the wall, the starting ‘reservoir’?
Are walls drying out, and how fast?
Are they drying steadily or are they occasionally re-wetted?
Is there any rot risk and if so where?
What’s the effectiveness of DPC’s
Are joist ends in good condition?
What’s the condition and effect of capillary active materials? (if you have any)
What’s the temperature across different building assemblies
What’s the humidity in crawl spaces and basements?But with the sensors in the right position and a bit of calculation you can answer much more interesting and useful questions …..
Is there any mould risk and if so where?
How does mould risk change over time?
How likely is interstitial condensation from internal moisture? What time of year? How big is this effect and should we be concerned?
Is rain adding much moisture to the wall?
In what layer of the wall is the moisture greatest and where is capillary action taking it?
Are there any difference in the evaporation for treated and untreated walls? What’s the effect of diffusion membranes?
What’s the effect of sun on IWI systems?
What’s the effect of EWI on masonry?
Is it drying inwards or outwards and is there a specific time of day when it is greatest?
The AECB has done this for about 10 case studies in the CLR Retrofit course and is considering offering a Monitoring Analysis Service to give these answers on your project. A brochure for this is attached, if you're interested please let me know, this could be available as soon as fee arrangement has been sorted out.
