Land is our capital; through the sunlight that falls on it, it captures the necessary annual energy and mass of resources. But closely related to this is water, which is essential for that land-sun system to function and is the most important source for humans after air/oxygen. It should be…
The Earth is a physical subsystem of the universe, and the physical processes within it are fairly well-known and describable. For example, concentrated reserves of raw materials are limited, and within such a finite system, infinite growth (organization of molecules) is not possible. This is bound by limits, just as…
Everything that doesn’t last at least 50 years is a step backward. It signifies a decline in the physical-biological system potential. If that system—Earth—is already fully burdened, beyond regeneration capacity, or I other words: if we are living above our personal resource bubble (beyond our physical-biological means), it becomes extremely…
Our biggest problem is that people, or humanity, do not observe or respect boundaries , to anything, and when facing them, they also want to constantly push those boundaries. And when starting to talk about boundaries, it quickly becomes a discussion about the freedom to choose for oneself. During Corona,…
Last time I wrote about about project development, and how everything was optimized within project borders, but the effects outside the project boundaries were neglected. But between architect and client, it’s just the same, and even worse, as became evident once again when I attended a presentation about a new…
A building is usually assessed sec, as a building. Or as a complex of buildings, within the project development boundary, both energetically and financially. See previous contribution. But that is often at the expense of effects outside the project boundary. A few examples can clarify this. Some years ago I…
In projects with students, it regularly clashes between economic and environmental cq climate objectives, and thus also between real estate and building physics tutors. Or between ‘the project developer’ and the ‘energy calculator’. And the battle is fought over the heads of the students ; they have to find a…
It is common in construction to normalize per m2 floor: such as e.g. energy, material, ventilation needs, or even costs and investments. But when it comes to the national requirements for housing in fact you should not calculate per m2 floor. Because it’s not about the impact per 1 m2…
In the agricultural project that I described in my previous contribution [1], which was initially about the EROI, the energy return on energy investment, I subsequently calculated the effects back to land’input’. But then the thought soon arised: would is also be possible to develop a LROLI, a Land return…
Storage (binding) of CO2 in wood/timber is a hot issue at the moment*. But how should that be calculated really? Before I go into more detail, a few preliminary remarks: (the part on ‘calculating’ has been later added, and ‘CO2’ has been adapted) Building in wood is always a good…
