Solar gain through my basement windows.

I just wanted to share a bit of the datalogging chart from today. The orange line is my recroom, the blue my office. My office is north east corner of the house. The recroom the southeast corner with a 6'x2' window in it. THe small spikes you see are from the fan in the forced air system kicking on to circulate. The woodstove is out, the furnace is not heating.

Today is the first day in almost 3 weeks that it has been sunny and the house feels noticably warmer especially upstairs where there is lots of south facing windows. I'm glad the chart caught today heat gain in the basement.

the grid line below the orange is 20C with each step being 5C so the sun raised the temps in the basement from an overnight low of 19.43C to a current high of 23.55C the sun is now moving to the point it won't come in the basement window but upstairs will get a couple more hours of heating. I can't wait to get more temp sensors.
