Hello Frances:

I have never seen anything that covers the risk of developing mold in houses.

I have had mold develop on the ceiling of one room in my house, here in Florida in the wintertime. I solved that problem by (a) painting the ceiling with paint that contained a special chemical, (b) adding insulation to the outside of the house (c) adding insulation in the attic (d) upgrading to a heat pump.

If flooding of the house were to occur due to storms/hurricanes during summer, then mold will form on the walls within a few weeks and there is nothing one can do.

But there are certainly things one can do to avoid making it worse, mainly monitoring humidity and encouraging air exchange at times when the air outside is drier. Heat recovering trickle vents are expensive compared to simple fans, but are less likely to lead to cold spots,  Generally houses in flood risk areas will be solid floor downstairs, and things like tiles and painted render inside, instead of carpet and wall paper. Cavity wall insulation closed cell foam rather than rockwool, that sort of thing. (only if it is young enough to have cavity walls at all of course.)

Not sure how much understanding is new but there are certainly courses on how to do assessments.

https://ukcmb.org/training-and-cpd/ for example - their diy on line calculator seems to be broken so that cant be tested right now.

Thanks Mike,  the 'use case' for detecting conditions that could lead to mould development is a commercial one. We already have  regular  temperature and humidity reading data for the environment, keen to explore how to use science to indicate if there's a risk of mould developing. 

Thanks Peter, the use case for what we're trying to do is large residential properties, we have temperature and humidity data, keen to explore if science can help us detect conditions for risk of mould development.

certainly you should be able to - the humidity is most important, and that is affected by temperature as that relates to condensation risk, but ideally also you need to have ventilation rate information or a model - or you will be identifying all 65% plus humidity areas in a building as being at risk, not just those with a lack of air changes or warm temperature..
