2021 March
Fall is here, but we just ticked out of the HRV's need to cool zone at the end of March. In March we ran the A/C on 4 days on a noon until 6pm schedule to take advantage of the solar production during that part of the day. The main source of cooling continues to be openning the windows during the cooler evening / nighttime hours, although towards the end of March we've not been doing much nighttime ventilation. THe HRV is working well and we done with the experimental period (I've sent the ERV core back to FanTech)! March is a "normal month" typically one adult is at work while the other is working from home, but we are increasingly spending days in the office.
| Inside / Outside | % < 20 °C | % 20 - 25 °C | % > 25 °C |
|---|---|---|---|
| inside | 0% | 84% | 16% |
| outside | 34% | 25% | 41% |
Methods: I have taken the 5 minutely data from the wirelessTag sensors and calculated the median temperature for each hour and determined the proportion of hours falling inside of the 20 - 25 °C target temperature (using the R functions 'aggregate' and 'hist'). Inside includes data from 12 wirelessTag sensors spread across every room of the house. Outside is the data from the wirelessTag sensors outside near the cubby house and HRV intake. The water wall and door data are not included.

Methods: I have taken the 5 minutely data from the wirelessTag sensors and calculated the median temperature for each hour and determined the indicated quantiles for each sensor (using the R functions 'aggregate' and 'quantile'). Inside includes data from 12 wirelessTag sensors spread across every room of the house. Outside is the data from the wirelessTag sensors in the cubby house, outside, and HRV intake. The water wall and door data are not included.
Monthly electricity data. We generated 378kWh, we used 346kWh, so we were net energy producers for the month (1.0kWh/day). Because we don't have batteries, we exported 218kWh and imported 186kWh. We now have a complete year worth of solar data, so expect a summary post on that once my work settles down a little bit.
