Strange, really, that calculating in kWh seems normal for everyone. Especially in this time, because kWh does say nothing about the origin of the energy, which can be anything, from labor, wind turbines, or coal to nuclear energy. Currently it is an important measure of energy use in buildings, the…
(master-classes on this topic and others, see on the right) ” What is Circular Building really?” , a Dutch journalist twittered, being confused about the debates going on. Its not clear yet, apparently, so lets give it a try. The word “Building” we all understand, its about the word Circular…
In the previous article, in which the energy and mass conversions are described at different moments in the flow of a cycle, the role of biomass as driving energy for a resource cycle was underexposed. But let me be clear about this: Biomass a energy source is no option. First…
Policies, (financial-) economy , technology, religion, and even science to some level, are all human thought up constructs, that are not grounded in physical reality, but in human perception of life and how to live it. There is no natural law that has to be followed, they all can be…
Last week, was a week with some Aha moments, and forced to rethink a few issues. Among these a continued discussion in The Netherlands with Jan Willem van de Groep, the passionate protagonist of Nill Onthe Meter retrofits (NOM). Nothing wrong with that, but to establish fast and large CO2…
(below is a improved English text compared to the first one published. Thanks to (editing by) Simon McGuinness..!) The circular economy, is about closing production cycles, is it not? So, it is about restoring the original stock. Otherwise the resource is depleted, and we run out of stock. Yes? But…
It started dawning, the past weeks, as I was listening to some presentations on several events I visited. Have you ever wondered what in fact it means, renovation or retrofitting houses and buildings for 0-energy performance? A focus on operational energy, for heating and ventilating, has become completely irrelevant. It…
Its Christmas , the shopping rush is over: and we all have been victims of buying anger, or better: victims of a system that forces us to buy and sell, and overrules all social and cultural behavior. And many will have bought a Christmas tree, at least people in the…
After Paris, no one can go round anymore: every sector will have to contribute to CO2 reduction, even the building and construction sector with regard to its material choices. And why not start immediately with the easiest solutions, the low-hanging fruit so to say, mainly the shamelessly framing of some…
The Paris climate agreement puts materials high on the agenda, since its about a 0-CO2 emissions target, which addresses material resources and production as well as energy: materials require lots of embodied energy energy ( see blog on buildings as Carbon bombs) , and in fact the 0-energy targets in…
