Thornleigh Passive House

September alternated hot and cold(median temperature 17 °C). Outside temperatures ranged from 6 to 28 °C, while inside we were a comfortable 18 to 24 °C. The HRV was mostly between seasons abd the split system was off for the entire 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'). Inside includes data from the wirelessTag sensors spread across nearly 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. Energy production and consumption: 1. tota

August started cold and ended hot (median temperature 15 °C). Outside temperatures ranged from 3 to 30 °C, while inside we were a comfortable 18 to 24 °C. The HRV was in heating season for the first half of the month, but entered the cooling season the for the last couple days. The split system was set to heat during peak solar production during the first half of the month, and off for the second half. Spring flowers were out in full force by the end of the month!

July was as cold as June (median temperature 11 °C) but not quite as gloomy (9kWh/day of solar production). Outside temperatures ranged from 2 to 22 °C, while inside we were a comfortable 18 to 24 °C. The HRV was in heating season the entire month, and the split system was set to heat during peak solar production (not that we had a whole lot of sun in June) and set to heat to 18 °C overnight for the entire month.

June was decidedly cold (median temperature 11 °C) and gloomy (8kWh/day of solar production is an all time low). Outside temperatures ranged from 2 to 22 °C, while inside we were a comfortable 18 to 23 °C. The HRV was in heating season nearly the entire month, and the split system was set to heat during peak solar production (not that we had a whole lot of sun in June) and set to heat to 18 °C overnight for essentially the entire month.

International Passivehaus Open Days - June 2024 edition. We were open and hosted 40-50 people (didn't get an accurate count). We met some lovely people and chatted passive houses. Just because folks asked... a couple of graphs (using the same hourly data from the monthly summaries). An updated all available data (40,133 hours) histogram: An important note on these data. More than half of the hours above 25 °C (546/1026) occurred in the first 6 months of living in the house, and all of the hours where the inside temperature above 27 °C were in the first 6 months living in the house when we were still determining the optimal HRV settings and how to manage the house temperature (learning that a passive house is designed for temperature inertia and benefits from a set and forget approach). Looking at 37,258 hours between March 2020 - June 2024, the house is in the passive house target zone of 20 - 25 °C 95% of the time, and in our target range (18 - 12 °C) 99% of the time. The 18 °

May was decidedly wintery (median temperature 14 °C). Outside temperatures ranged from 5 to 24 °C, while inside we were a comfortable 19 to 24 °C. The HRV was in heating season nearly the entire month, and the split system was mostly set to heat during peak solar production (not that we had a whole lot of sun in May) for essentially the entire month.
