As per the title, I'm wondering if anyone with MVHR has kept a log of internal temperature and humidity data. I'm playing with the free version of WUFI, and while it can derive the internal climate by adjusting external climate data to take into account heating and aircon, there's nothing for MVHR. Which seems a surprising omission, unless it's only in the paid versions. In the absence of that, the next best option would be to define sine curves for the internal temperature and humidity, but there seems to be a lack of easily discoverable data on that. I've posted my initial guess below, but it would be good to have something to validate / correct this against:

Our liquid floor screed is drying off: all windows and doors open all day - this weather is helping a lot I'm sure. Someone on BH suggested we put a sheet of plastic on the floor to see if there was any evaporation: a quick , dirty check. So I have done. When I remove the plastic sheet, the area covered by it is significantly lighter in colour than the area which has not been covered. Why would that be so? Instinct says the opposite might be the case (because there will have been less transpiration / evaporation). Anyone know why , first thing in the morning the screed is a lighter colour under the sheet than everywhere else?
