Recently, I read some interesting books again about developments in quantum physics and space relativity, essentially the micro and macro aspects of physics, and the attempts to unify the two. It’s not entirely my field, but incredibly fascinating. What I struggle with most in the formation the theory are the…
We are often called upon to change our behavior: stop buying bullshit, fly less, avoid fast fashion. Sometimes, it is even enforced by the government: buy an electric car, insulate your house, or install a mandatory heat pump, for example. A call for ‘flying less’ however doesn’t translate to flying…
The year 2100: Finally! It’s the year 2100, and for the first time, CO2 emissions from buildings will start going down. It should have been already zero by 2050, but due to spreading emissions over the lifespan of buildings, it’s only mathematically the case from 2100 onwards. Yearly that will…
A building is usually assessed sec, as a building. Or as a complex of buildings, within the project development boundary, both energetically and financially. See previous contribution. But that is often at the expense of effects outside the project boundary. A few examples can clarify this. Some years ago I…
There is a lot of discussion in the Netherlands about how to assess buildings, if you integrate material impacts in addition to energy, as well as to somehow include CO2 budgets. There is already an instrument for this, the MPG, (materials performance Buildings) but it is under discussion. Besides, in…
Of course, it makes some sense, improving our house with some insulation, a heat pump and so on (or not, I’ll come back to that soon!) , but if you could choose where to live or build, or move, where would you go, given that you want to be prepared…
I was asked that question last year by Thomas van Belzen of Cobouw,[1] and it got me thinking. It was an interview in Dutch, but let me return to it in English and in more detail at the beginning of 2023. The first reaction is of course: why build, we…
It is common in construction to normalize per m2 floor: such as e.g. energy, material, ventilation needs, or even costs and investments. But when it comes to the national requirements for housing in fact you should not calculate per m2 floor. Because it’s not about the impact per 1 m2…
Last week, two interesting reports were published analysing how regulations can better support ‘sustainable’ material use. Very esteemed colleagues, united in a Dutch ‘Gideons tribe’ to make the buildings sector move faster, have been working on this. [1] I can agree in general with the contents and analyses ( to…
With vegetables, we’ve been doing it for years: most current vegetables never existed, in an autonomous evolutionary process. We as humans have slowly transformed them so that they grow the way we appreciate them, and want them on our plates. (Or the industry has adapted them the way we want…
