2025 January

January was summer (median temperature 21 °C). Outside temperatures ranged from 13 to 42 °C, while inside we were a comfortable 20 to 25 °C. The HRV was in the cooling season and the split system was on during the solar generation period. For much of the month overnight temperatures did not drop below 20 °C, so openning windows in the evening wasn't an option for cooling the house. Temperature from inside and outside the house as the percentage of hours in 0.5 °C bins. I've scaled the temperature in hope that I will be able to use the temperature range for all months. 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 the wirelessTag sensors spread across nearly every room of the house. Outside is the data from the wireles...

2024 December

December was a lot like summer (median temperature 22 °C). Outside temperatures ranged from 14 to 39 °C, while inside we were a comfortable 20 to 24 °C. The HRV was in the cooling season and the split system was on during the solar generation period for about half the month. During the second half of the month we experiment with only using the A/C & HRV (not openning windows in the evening). Temperature from inside and outside the house as the percentage of hours in 0.5 °C bins. I've scaled the temperature in hope that I will be able to use the temperature range for all months. 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').
