Water update...

We've recieved three water bills since moving in (how time flies)... for about half that time we have been working from home and even had the kids at home for six weeks. Even with all that we've done really well. 

City water: the quarterly bill from the "old normal" was 172L/day, the lock down quarter was 198L/day, and the working from home quarter was 180L/day. So not too much variance really, and 183L/day over three quarters is good and puts us at 46L per person per day... about 20% of the typical Sydney resident. 

Rain water: Since moving in we have been able to supply our laundry, toilet and garden needs for all but one week in January... without having to water some of the new plants we probably could have made it 100% on rain water for those needs. I plotted rain fall (from the NetAtmo rain gauge which is excellent) and water level in the rain water tank (using a Vegetronix AquaPlumb sensor, which the individual measurements (hourly) are kind of noisy and a little cumbersome to download - but the daily average seems to be good) up through the end of May. I also splashed out on the Kingspan SenSit system, but it has yet to provide anything close to accurate or usable.




The top is daily rain fall. The bottom is median daily water tank level based on hourly recordings (filled polygon), the lighter/darker shade around the median line is the interquartile range of the hourly measurements. The tank was intentionaly emptied at the start of February in anticpation of the forecast rain. The dotted availabilty line is plotted based on the height of the tap.

Temperature (Out vs. Old vs. New)

Image
I have fielded more than a few questions about the temperature of our passive house versus the temperature of the house that we lived in prior (on the same lot).  So I've used the data I had on hand which is temperature (°C) recorded every 5 minutes over since October 2012. For the sake of consistency I am only using the NetAtmo sensors that I have had for that entire period. So I only have one outside sensor and one inside sensor located in the the respective living room. The outside sensor moved around a bit, but it should be good enough.  I've converted those measurements to hourly averages.  This ends up being ~ 66,955 hours to play with (52,232 hours from the original house, 14,723 hours from the passive house). I've left the rental house out of this comparison, but it was disturbing like the original house despite being ~ 20 years old. The key take-home messages: The passive house a much less variation in temperature than the original house (or outside).  In the summe

Water wall...

... Currently a work in progress... Thermal Mass A material’s capacity to absorb, store and release heat. Thermal mass is typically used to moderate temperature extremes by releasing heat when the home is cool and absorbing heat when the home is warm. Specific heat capacity A material's capacity to store heat (measured per unit mass). Some materials are better at storing heat than others. Water can store 4× as much heat per kilogram as concrete. Density Mass per unit volume (mass / volume). Denser materials have more mass per volume so they can make up in density what they lack in specific heat capacity. Concrete has twice as much mass per m3 as water. Thermal conductivity The ease with which heat travels through a material. Ideally, thermal conductivity should be moderate so that the absorption and release of heat synchronises with the building's heating and cooling cycle. Both water and concrete are highly effective! In comparison, steel and water hold a similar a

international passive house open day...

We had ~49 people come through the house for one of the International Passive House open days of 2019. As the event is not as widely publicised as Sustainable house day when we had more than 200 people through. The visitors who came through for this open house tended to already know a fair bit about passive houses (with many dragging along family members who they were working to convince of the merits of passive house living). Lots of the visitors were already planning or working on projects that were including passive house principles.
