Today, such systems are still controlled on the basis of a conventional if then, else control. Represented in a so-called 'Sankey model' Top: From left to right the representation of energy flows through a building. Already this is a particularly complex interplay, with every choice made affecting the overall installation, energy consumption and final heating or cooling of the building. But this energy can also be brought to the zone via the intake grilles, and at the same time the sun can also provide additional heat in this zone.For now, we cannot control the sun (unless through a sunshade), but all these other components can. The interplay between these components ensures that if we transfer 10 KW of heat from a boiler via a manifold to the underfloor heating of a particular zone, it will heat up. In addition, the outside temperature and the wind on the façade also play an important role in the so-called transmission losses, the leakage of heat to the outside due to a colder outside temperature. You don't have to be a techie to understand that all these components are interrelated. Together with solar radiation, which is added for free, all these components - if all goes well - provide the desired temperature. Together, they form the energy flow through the building, from procurement and generation to distribution and release. Finally, these are connected to the energy supply as we have at home. These systems are in turn connected to heat or cold producing installations such as a natural gas boiler or an electric heat pump. In turn, the underfloor heating and intake grilles are connected to air treatment systems, manifolds, buffers and sometimes heat recovery systems. But the sun radiation on the façade also influences the temperature in the building. The different zones are heated or cooled via (hot) water or (cold) air that is distributed throughout the building via, for example, underfloor heating or intake vents. Usually, the building is divided into a number of zones, e.g. For this, let's first zoom in on how a (larger) building installation works. And formulas can simply be computed faster by a computer than by a human.Ībove: 1997 Deep Blue wins by Garry Gasparov.Įxactly the same is possible for controlling installations within a building to get it up to temperature or even managing an entire energy grid. Each set within the game became a calculation. IBM's computer converted the game of chess to a set of mathematical formulas. The seemingly impossible became a reality, but how was it possible?The answer is simple. A legendary moment for the IT world, a moment of disbelief and outrage for the chess world. Back in 1997, world chess champion Garry Gasparov was defeated by Deep Blue, the chess computer developed by IBM. The comparison with a game of chess is easily made. At more than 50 buildings, we have now achieved savings of up to 40% and well-functioning installations. We also increasingly use heat recovery systems or store energy in batteries.įor the algorithms of ecoBuilding, the party only starts at this complexity: the system manages to make the best choice at every moment. The control of buildings and installations is becoming increasingly complex as we make more use of advanced and sustainable systems and renewable energy sources: today, we do not only generate heat with boilers, we also get it from the ground or the sun.
