This is an excellent summary of the MBIE proposed discussion document and the options proposed. I know how bad NZ buildings can be in terms of basic moisture management and insulation but even the ‘high’ options seem inadequate to fix the problem entirely. These will certainly improve rentals but seem not able to actually make them warm healthy homes unless …
Australian Passive House Association first bi-annual Sydney Symposium Wednesday 26th September 2018
This has some great speakers and should really push high performance building forward in Sydney. I’d especially like to hear the breakfast panel discussion on “transitioning to a zero carbon building and construction sector” and how to make that happen be affordable and societies obligations to make it so. Great speaker lineup with the conference theme of Building Responsibility: Aiming towards …
28 August 2018 Stuff’s Hamish Mcneilly: Council confirms six-figure support of NZ’s second co-housing project
Excellent but brief article on an awesome multi-family project that is targeting the Certified Passive House standard. I remember being asked to estimate the work involved in certification and then being invited to a public talk on this project not realizing they were the same. It was pretty fun sitting there and hearing Catherine Spencer talk about the dramatic benefits …
27 August 2018 The Guardian’s Damian Carrington and Lily Kuo: Air pollution causes ‘huge’ reduction in intelligence, study reveals

So air pollution is not only stupid but makes you stupid especially if you are male and older. Wow! Sometimes you can’t make this stuff up. This article in The Guardian is pretty scary especially as air pollution is an issue in many NZ cities in the winter. As we spend much of our time indoors most of folks exposure …
23 August 2018 The Fifth State: On why ethics is the thing we most need and is sadly in short supply
This article starts by reminding us of the finance industries poor ethical practices of charging dead people fees but soon moves on to the similarly un-ethical dilemmas in how we choose to build buildings. Sometime I’m in shock when someone asks why we need to predict and understand how buildings perform before they are built; especially when you hear experts …
22 August 2018 The Fifth State’s Willow Aliento: Support urgently needed for Storer’s bill to make rental housing bearable in extremes
This bill is about tax treatments; to encourage property owners with low cost rentals to invest in energy efficiency – especially the building fabric. But from my perspective the point from this article is how horrible split incentives are. We have this same split incentive issue in NZ. The split where landlords pay for the building and capital upgrades but …
22 August 2018 The Spinoff’s Ethan Donnell: Mould, sweet mould inside New Zealand’s damp housing crisis

I see mouldy houses quite a bit in my work but this Spinoff article still shocks me with the impacts on occupants. Most of the bad buildings in this article are in Wellington, because that’s where the writer is located, but I’ve seen even worse examples in Auckland and Christchurch. The statistics are pretty grim with over 40,000 children hospitalized …
Case Studies on Certified Passive House Projects – example Kowhai Passive House
Sustainable Engineering is putting together a page on all of the New Zealand Certified Passive House Projects. We will start with projects we have certified ourselves and then add in all of the remaining ones certified by others. The intent is to put up the sort of data that we ourselves tend to want to know about projects; like floor …
16 August 2018 The Fifth Estate – Melbourne’s proposed Green Spine “could be benchmarked to Passive House standard”

This past March at the Passive House Conference in Munich, Germany, I had the opportunity to meet with Dieter Herz of Herz and Lang. One of the founding members of a very experienced & prestigious passive house design consulting firm in Europe. During our discussion and later in his presentation, I was a bit surprised at the level of emphasis he …
