2025 November

November: the sun was out except for a few days, and summer was here albeit will nice cool evenings (median temperature 20 °C). Outside temperatures ranged from 9 to 35 °C, while inside we were a comfortable 18 to 25 °C. The HRV was in the cooling season and the split system was mostly on during the days and off during the evenings when the windows were open. With the sun out the solar production was solid. We had a dozen or so visitors through on International Passivhaus Open Days. Always a fun day to chat with people about our Passivhaus journey. 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 hou...

2025 October

October: the sun was mostly out, and some silly alternation between summer and nearly winter temperatues (median temperature 19.5 °C). Outside temperatures ranged from 10 to 38 °C, while inside we were a comfortable 19 to 25 °C. The HRV was in the cooling season and the split system was mostly off. With the sun out the solar production was solid. 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 'aggregate' and 'hist'). Inside includes data from the wirelessTag sensors ...

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.

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.

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.
