Klimaatneutraal bouwen en renoveren heeft een ingebouwd dilemma: niet alleen energieneutraal, maar ook de materiaal CO2 telt mee. En hoe beter de een scoort, hoe slechter de ander. Deze catch 22 , lijkt redelijk gedresseerd met de introductie van een… Continue Reading
Met energie in de gebouwde omgeving hebben we nu redelijk door, hoe de hazen lopen. Om fossiel uit te bannen als bron, creëren we 0-energie huizen en gebouwen. Dwz die gebruiken nog steeds energie, maar geheel zelf opgewekt door met… Continue Reading
Laten we eerlijk zijn, wie kan er ook maar iets tegen 17, onlangs door de UN gelanceerde, ‘sustainable development goals’ hebben? [1] Wat is er tegen vrede en gerechtigheid? Of tegen gezondheid ? Of tegen innovatie in industrie? OK, de… Continue Reading
As the Belgians built a polar station in the Antarctic, they wanted to do a good job and make it a 0-energy project, ZEB. The main item was to become more or less energy autarctic. wind-turbines and solar panels should… Continue Reading
There is a wide conviction among people that there are resources that can be renewed, and some that are non-renewable. How come, why is this (mis-) understanding so widely? Is it just convenient to look at it like this? In… Continue Reading
The earth in fact is one big island, on which we have to try to survive. Which was until recently not such a big deal, but with 7 billion of, and increasing to 9,5 billion by 2050, its about time… Continue Reading
No two closed cycles, but only 1 and the same, for all resources, biotic or abiotic, renewable or non renewable, only with different loop times and routes ( see previous blog) . That we regularly see two cycles turn up,… Continue Reading
(About resource racism… ) Closing cycles is at the hart of decreasing environmental impact: at the same time resources are the foundation of societal development ( water- food-materials-energy). So to maintain a certain level of welfare , the resources are… Continue Reading
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… Continue Reading
When constructing a building or a house, there is need for access to the building. The more wealthy a nation the more sophisticated the infrastructure will be . After dirt roads, a stabilized road is build, followed by a constructed… Continue Reading
