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…

The Quest in Egypt is actually quite simple: Not look for reductions of fossil, but how to live off the sun, and its derivatives, wind and water power. And where possible make things a little more effective with a little gravity and geothermal power. That’s it, in terms of energy…

Calculating in CO2 remains a challenge, especially when it comes to the remaining budget. There is in the Netherlands a small action group that is trying to define how we should deal with the remaining CO2 budget for the built environment. How much CO2 may be emitted (invested) per new…

During my time as a professor I was regularly at odds with the Academy of Architecture’. I feel affiliated with ’the art of building’, but not with architecture or construction as art. That was more or less the reason for the quarrels. Not surprising, because in my guidance I start…

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…

There is a lot of discussion, how to ‘fight’ climateheating. Especially now, with massive investments in the economy. But what is clear, is that every sector has to make its contribution, to become carbon emissions free. Every sector? Yes. We were sitting together with some old rugby friends recently: So…

Before we hurry covering everything with solar panels, let’s reason a bit further, because since my first experiences with renewable energy, many new insights have emerged. Those first experiences I had when building a “Bicycle wheel windmill”, as described in the “Windwerkboek” of the time. [1] ( Wind Work Guide)….

As we want to get rid of fossil fuels, we will at least have to develop everything now without fossil fuels. And in any case the operational energy. In the case of new buildings this leads to “0-energy buildings”, which generate as much renewable energy as required, locally, and thus…
