Humidity can also make it feel colder than the actual temperature if its too low. Your initial analysis may say something like 7,000 mold spores per cubic meter of air for a humid vented crawlspace during the middle of the summer, with visible mold and then you may seal it all up, install a dehumidification system, or do waterproofing and 8 weeks of dryness later after your mold sampler has crawled through the now dusty crawlspace knocking everything down and picking everything up to start your follow up test after the work done, you may have solved the humidity problem, made the space much more inviting and clean, but get an analysis back that there are 77,000 mold spores to the cubic meter. Outdoor temperature/dew points of 60/50, when brought inside and heated to 68 degrees, yields a relative humidity of 52 percent; outdoor readings of 0/-5, for example, when heated to 68 degrees indoors gives a low 5 percent relative humidity.
