WE did a 2 mile walk today. I worked on the AVSA website and finally found the problem with the Colorbox. IT had the wrong name. Instead of plain Colorbox it was named colorbox1.x After a rename it started working normally which was great news. Dinner was leftover fish and chips with a salad. During the evening I read about crawlspace encapsulation vs crawlspace ventilation. In general encapsulation is bad and ventilation with a huge exhaust fan is bad if it's humid outside. I need a smart system that compares the outside humidity with the indoor humidity and only exhausts when the outside humidity is lower than the inside humidity. The blogs insist that I need to compare dewpoints instead of humidity. i agree. The indoor dewpoint will need to be calculated whereas the outdoor dewpoint can be scraped from weather underground using either my website data or a nearby site or possibly a combination of the two with one serving as primary and the other as backup.
