Biobased resourcing is hot. Which is understandable, of course, they grow by themselves, (its solar energy), they capture CO2, require little energy to process, and know multiple uses. You can built with then, heat, or create high-value resources, like in… Continue Reading
This is an extended version of a previous post on linked in, which had a lot of reactions.. {april 2019} When it comes to Embodied Energy, we are used to normalize this over the lifespan of a building (… Continue Reading
A few months ago I wrote about agriculture, and that the EROI was 0.16: 1 (energy return on (energy) investment) – on average across all agricultural products in the Netherlands, and the EL (Embodied Land) no less than 7.7 ha-year… Continue Reading
Last month I finally visited the ‘2226’ office in Austria near Bregenz. The building, realized about 4 years ago, already won many prizes. What is special about this building: it has no heating system, and in fact no ventilation system,… Continue Reading
Before going into agriculture, and the available figures for it, I will briefly summarize how evaluate keeping resource loops closed. Fot this a calculation method has been developed, called MAXergy, with Embodied Land as a measuring unit. To close resource… Continue Reading
How are we going to ensure that buildings will be sustainable, that is to say, with the least impact on the environment, concerning raw materials depletion, loss of biodiversity and, above all, CO2 emissions as the most urgent effect of… Continue Reading
Do we really want a CO2-neutral society, or even a society with closed cycles? If yes, a lot will have to change and we will need to become extremely creative. And not directly with the input of a lot of… Continue Reading
( picture: borrowed from: Agent Bob) … Well, then, what is a circular road? was a question that was asked , after the previous article. To answer, lets first analyze what happens when constructing a highway with current approach. Then… Continue Reading
Henri George, during the end of the 19th century, was a renowned thinker and writer. His central theme was Land. He saw land as a vital good, to give everyone a basis to live from. But he also saw that… Continue Reading
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… Continue Reading
