Thornleigh Passive House

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. 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 ...
