In the Spring, Summer and Fall we typically use much less electricity than in the Winter.
Last year (2016) June and September were our lowest months. This year we are averaging about 100 kWh more each month which is a 10% - 15% increase. Most of this increase is because we are now running the basement mini-splits in dehumidify mode to reduce the moisture.
In June, for example, the temperatures were very pleasant and we didn't use any AC. However, we had 6.8 inches of rain and the average outdoor humidly was 83.6%. In the basement the humidity levels were even higher.
- May 997 kWh - 32 kWh/day
- June 866 kWh - 26 kWh/day
When we were designing the house I didn't anticipate that humidity would be such a problem on the lower level. After all, it is a walk out basement with patio doors and large windows. I imagined that we would get plenty of fresh air through the doors and windows.
I did not anticipate the BEARS.
They visit several times a week and sometimes spend the night behind the woodpile or come up to the front porch to get a drink from the birdbath.
The cubs are so CUTE. There are actually three cubs but I can never seem to get a picture of all three together.
She also seems to enjoy sitting in front of the heat pump and letting the hot air blow on her. I can't imagine this feels good but I'm not going to argue with Mama!
So... getting back to the point; we don't leave any doors or windows open at ground level when we aren't in the room. It's better to spend a little more on HVAC than discover a confused/angry bear in the basement.
