March: Summer was still here until the end of the month. Outside temperatures ranged from 11 to 33 °C (median temperature 21 °C), while inside we were a comfortable 19 to 26 °C (median 23 °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 (evenings were cool enough to open the house at night less than half the month).With the sun mostly out the solar production was solid. We had about a week with the HRV out of service due to a temperature sensor failure. This results in the exhaust fan working, but the intake fan shutting down. So operationally you tilt open a window at the far end of the house to let air in, the HRV continues to exhaust but no heat recovery happens. FanTech was great and sent out a replacement sensor which I swapped out so the HRV is back up an running. Not ideal, but why the inside temperature ran a bit warmer this month. During this period of time the house CO 2 levels...

February: Summer was here. Outside temperatures ranged from 16 to 38 °C (median temperature 22 °C), while inside we were a comfortable 20 to 25 °C (median 23 °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 (evenings were cool enough to open the house at night less than half the month). With the sun mostly 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...

January: Summer was here. Outside temperatures ranged from 14 to 41 °C (median temperature 21 °C), while inside we were a comfortable 20 to 27 °C (median 23 °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 (evenings were only cool enough to open the house up about half the month). With the sun mostly 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.

December: the sun was out except for a few days, and summer was here albeit will nice cool evenings (median temperature *21 °C). Outside temperatures ranged from 10 to *39 °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. *Of note, the outside data is missing 3 of the hottest days of the month (18th-20th). By chance, those days happened to be the days when the batteries in both sensors had died. 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.

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.

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 ...
