2023 June

Image
June was definitely cool and really felt like winter (median temperature 12 °C). The HRV was solidly in the heating season, and the split system was to heat to 23 °C during peak solar production for most of the month. Outside temperatures ranged from 1 to 24 °C, while inside we were a comfortable 18.3 to 24.6 °C. We have opted to keep the house in the World Health Organisation temperature range (> 18 °C) during the heating season because we are very comfortable sleeping with a blanket on the bed. 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 ...

We had about 40 people through the house on Saturday morning. Thanks to Andy from Envirotecture , Trent & Garrett from Red Cedar Constructions , and Jason from Logikhaus who were on hand to help with the specialist questions. The next IPHA Open Days are November 10 - 12th .

2023 May

May was definitely cool and really felt like the start of winter (median temperature 12 °C). The HRV was solidly in the heating season after the first week of the month, and the split system was to heat to 23 °C during peak solar production for most of the month. Outside temperatures ranged from 3 to 24 °C, while inside we were a comfortable 18.4 to 24.2 °C. We have opted to keep the house in the World Health Organisation temperature range (> 18 °C) during the heating season because we are very comfortable sleeping with a blanket on the bed. 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.

2023 April

Image
Inside we were between 20 & 25 °C 100% of the month and we used slightly more energy than we used. April was solidly fall weather with a large number of overcast days... it was definitely summer (median temperature 17 °C). The split system was off the entire month. The HRV was not in a season. Outside temperatures ranged from 9 to 28 °C, while inside we were a comfortable 20.4 to 24.8 °C. We had a few rainly days and a couple of very cloudy weeks. 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.

Open Homes...

Of all the press we have done (which is a fair bit at this point)... this was our fist foray into commercial television. James and the folks at North Light Productions were nice people to deal with, but it was a very differnet beast than working with ABC TV. In case you didn't guess Bondor was the sponsor for the segment on our house. The Passive House aspect didn't really get much coverage, but I do feel like I've said this stuff enough that it is coming out fairly well! Open Homes Australia, season 6, episode 7.

2023 March

Inside we were between 20 & 25 °C 100% of the month and we produced as much energy as we used (50% direct usage and the other 50% was exported and imported). March started with summer weather but ended in fall weather... it was definitely summer (median temperature 21 °C). The split system was on during peak solar generation for most of the first half of ther month. The HRV was solidly in the 'cooling' season. Outside temperatures ranged from 11 to 40 °C, while inside we were a comfortable 20.0 to 24.8 °C. We had a few rainly days and a couple of very cloudy weeks. 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.
