Beautiful English Passive House social housing apartments for the elderly: “18 apartments split into three blocks totalling 1057 sqm treated floor area. The larger block is comprised of 14 one-bedroom apartments at 55 sqm each, while the two identical smaller buildings each contain two two-bed apartments at 68 sqm each.” Unlike most project descriptions, this article has a refreshingly frank …
Surprise! Australian buildings have very similar problems to New Zealand buildings. They’re finding that mould is prevalent throughout their buildings because they don’t require designing to prevent mould in their building code. Because they don’t design cold spots out of the buildings or sufficient ventilation they have condendation and then mould in their buildings. And as we all know this …
Dangerous overheating in buildings may not be showing up in desktop studies, new research suggests.” “Monitored operative temperatures of up to 47.5C recorded in a highly glazed apartment building in London were not reflected in software modelling of the same building, with temperature peaks in simulated scenarios between 18C and 30C cooler, depending on which weather files were used.” …
This report reviewed detailed test measurements for air tightness and heating loads for passive houses and non-passive houses designed to meet an energy target. From this data the Passive Houses (Passivhaus in the UK) predicted performance matched quite closely to the measurements compared to other non-passive house designed buildings. “Most of the homes were fitted with mechanical ventilation with heat …
“I like to build for people, not for profit”. Quote from Isaac Davidson “If we’ve got a subdivision of 1600 new homes to build, you have to ask is it cheaper to build them to low specifications or build a new power plant, because that is where we are going. You spend 20% more to build each house to an …

I’ve had the opportunity to meet and hear her important research on the direct relation between really bad housing and bad health in children in New Zealand. The huge health care costs of choosing to build poor quality housing is shocking. And that is just the money never mind all the misery and …

The Building Enclosure and the Four Control Layers Understanding of the building enclosure and the four control layers that make up the building enclosure is vital to understanding how the building enclosure will perform Enclosure The building enclosure is what separates the inside environment from the outside ‘natural’ environment. This includes everything from the paint on the outside of …
Recently came across the great article on Passive House social housing planned at no extra cost in Melbourne, Australia from early last year. I’m looking forward to hearing about this project and some of the large commercial projects in Australia at the next South Pacific Passive House Conference in February 2019 in Wellington. We’ve two multi-family projects in NZ that …
