The natural radiant heat

Have you ever gone skiing on a glacier? Yes? Then you know this already! At lunchtime, you sit in the sun in a t-shirt and drink wheat beer and this at a temperature of -8°C. How is this possible? We are sure there is a scientist who will explain this to you in detail. However, can the whole thing be calculated? Only with great difficulty. And how is it with BBS thermo?

With the conventional regulators for calculating the heat load, stationary conditions of the building shell under laboratory conditions are assumed. Thus, the passive use of the solar energy in the wall and roof area, absorption of the solar rays, their storage and thereby the solar energy gain are unaccounted for. Calculating models exist already that take all of this into account. The so-called effective u-value of the building shell can be calculated in this way. A different effective u-value is given depending on whether the wall is facing north, south, east, or west. On the south side, it can even happen that the outside of the thermoline wall heats up due to the absorption of the solar rays, so that no heat can be lost outwards again. The heat from inside "accumulates" in the outer layer of heat.

BBS thermo building shells do not "know“, that they cannot be calculated according to conventional rules and therefore cannot be properly evaluated. This is like with the bumblebee. It has a wing area of 0.7 cm2 and weighs 1.2 grammes. According to the laws of aerodynamics, it is impossible to fly with this ratio. However, the bumblebee does not know this and just simply flies!

BBS thermo is absolutely sustainable and saves resources. If you combine the passive use of solar from BBS thermo with active use of solar by the use of a solar panel, the BBS thermo construction can be kept warm with only a small amount of additional energy.

With regards to all experiments, results and knowledge, we are working on drawing up an energy concept for BBS thermo. This integral concept should make it possible to estimate the expected energy consumption in the plan phase already.
