2025 September

September: the sun (finally) came out to play, and spring sprang (median temperature 17 °C). Outside temperatures ranged from 5 to 29 °C, while inside we were a comfortable 18 to 25 °C. At the start of the month the HRV was in the heating season and the split system was set to heat to 20 °C, but by the middle of the month the heat was off and the HRV was between seasons. With the sun out the solar production has rebounded 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. We have made a decision to keep the house above the WHO recommended 18 °C rather than the passive house standard of 20 °C. 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 'aggregat...

2025 August

Image
August was decidely wet (apparently the wettest on record) and cool (median temperature 12 °C). Outside temperatures ranged from 4 to 25 °C, while inside we were a comfortable 18 to 24 °C. The HRV was in the heating season and the split system was set to heat to 20 °C. Now that we have solar house batteries we no longer need to schedule the split system to run during solar generation as we have done prevously.

July was decidely wintery (median temperature 11 °C). Outside temperatures ranged from 1.5 to 20 °C, while inside we were a comfortable 18 to 22 °C. The HRV was in the heating season and the split system was set to heat to 20 °C.

2025 June

June was decidely wintery (median temperature 11 °C). Outside temperatures ranged from 2 to 21 °C, while inside we were a comfortable 19 to 23 °C. The HRV was in the heating season and the split system was set to heat to 20 °C. Now that we have solar house batteries we no longer need to schedule the split system to run during solar generation as we have done prevously. 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 wirelessTag sensors outs...

2025 May

May was decidely cool and wet (median temperature 15 °C). Outside temperatures ranged from 7 to 26 °C, while inside we were a comfortable 19 to 24 °C. The HRV was between seasons until the end of the month when it entered the heating season and the split system was set to heat to 19 °C. Now that we have solar house batteries we no longer need to schedule the split system as we have done prevously. 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.

2025 April

Image
April had a decidely autumnal feel (median temperature 18 °C). Outside temperatures ranged from 11 to 31 °C, while inside we were a comfortable 19 to 24 °C. The HRV was in the cooling season until the last couple days of the month and the split system was not used during April. At the start of the month we were openning windows in the evening as primary means of cooling house, but not at the end of the month. 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').

2025 March

Image
March had a decidely autumnal feel (median temperature 21 °C). Outside temperatures ranged from 13 to 36 °C, while inside we were a comfortable 20 to 26 °C. The HRV was in the cooling season for the entire month and the split system was on during the solar generation period at the start of the month (but not at the end). Overnight temperatures mostly dropped below 20 °C, so we were openning windows in the evening again as primary means of maintaining a cool 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').
