It’s finally happened. I’m reading a book that is living up to – and exceeding – the breathless accolades of commendation on the covers. It’s a particular joy for me. In the past, with quite a few books, I read a few chapters, become a little bored, and skip to the final chapter.
But not this one. I’m devouring every one of the 106 chapters over 563 pages.
It feels to me that the author has had so many ideas pent up that they decided to incorporate them all into one magnum opus. It’s fascinating.
Everything had gone to plan with the installation of the battery; performance was as expected. The savings generated by our PV upgrade and the battery were flowing into our Green Fund, enabling us to begin planning for the installation of our second battery.
Our modelling indicated that our 21kW PVs were generating enough power to usefully support up to about 55kWh of battery storage, corresponding to 4 x Tesla PowerWall 2 batteries. In cost-benefit terms, a sweet-spot would be with 2 batteries. In the depths of winter in July – on many days – we’d still generate enough spare power to fully charge the batteries for use after sundown.
Most shower heads at Christie Walk are WELS 3 standard, running at about 9L/minute. They were the best that were readily available when construction of our eco-village was completed in 2006. Older shower heads could be up to 22L/minute.
But the latest Ultra Low Flow shower heads run at 5L/min, and still give a satisfying shower.
Adventures with an environment-conscious inner-urban community
This was the crisis year for so many people – bushfires, COVID, job losses – and it also happened to be the year of our most adventurous emissions-reduction planning, carrying out 2 major projects a few months apart.
Stage 2 solar hot water boosters
The evacuated tube solar hot water boosters we had installed in 2018 were performing well, so it was time to build the second stage. We’d completed the design work in 2019 and had commenced the Development Application (DA) process with the City of Adelaide in September 2019. DA is required by Council if solar collectors are not mounted flat on the roof. After 9 weeks of back and forth, providing additional drawings and details, we finally received Planning Consent in mid-November.
