Dutch Future: Dryland and Boatland

It’s about time to face the hard truth here in the Netherlands: building below sea level isn’t handy, to say the least, to say modestly it’s destroying capital, and to say it hard: it’s endangering people. The soil is sinking, the sea level is rising, the rivers are overflowing, the…

Jaime Lerner – Curitiba

Just recently, in May, Jaime Lerner passed away. He more or less invented sustainable urban development. A little tribute. Everything has to be sustainable or circular these days, including the cities. Now, is there a city that has already applied many of these principles, where there is something to learn?…

Forgot 1 SDG (11) : Calamity proof cities

Last time, I even forgot one goal: Sustainable development Goal 11, Sustainable cities. Again, the question: what is sustainable? So much has been brought together under that heading, all nice things for people, that it does not really help us very much, when it comes to energy and resources. On…

Urban heat islands, a growing problem

Urban heating, or at least the increase thereof, has been in the spotlight for some time. And the basic effects were known to me. But after hearing a lecture by Math Santamouris during a recent Conference, a whole new world opened up for me. He gave a good overview of…

Transition: charging points madness

Amsterdam needs around 50,000 charging points for electric cars. 50,000? Really? Have we gone completely nuts or what? Doesn’t alarm bells start ringing: “What the hell are we doing?” Where do all these raw materials come from, and the energy to supply those charging stations? The electricity grid has already…

How (and why) to avoid high-rise buildings…

Architects love to be able to design and build an iconic tower. And a city counselor can leave his signature with it. Well, it happens that the world is urbanizing, and that we see a lot of high-rises in planning, framed as ’there is no other way’: we have to…

Circular cities..? Real time material flows for London

Since it looks as if we are going to introduce the climate measures for buildings mainly via municipalities or cities, I have recovered some of my older research material about urban sustainability, developed when I worked at Wageningen University. The urban approach makes sense, buildings are not isolated functions, they…

The end of the ‘road’…

The national organization for road works in the Netherlands, RWS, has a slogan: from A to Better. It has not brought us much so far: The roads are widened, more traffic lanes , so now we are not in a two lane traffic jam but in a 5 lane traffic…

Vertical F(r)a(r)ming …

There are some strange excesses in the need for more sustainability, and especially with regard to the undefined “greening” of things. One of these, and you notice it more and more, is the tendency to plant trees on buildings. Not on the roof, as you might expect, but especially around…
