A more realistic assessment of the heat requirement of buildings

16.01.2012
To optimise operations, integrate weather data in heating control systems

In spring and autumn in particular, there are many short periods of fluctuating temperatures caused by alternating warm and cold days. Inside a building, the effect of such temperature fluctuations is felt with a significant time lag. Quite often, enough heat is stored in building components and fixtures for a while; there is still plenty of waste heat or solar energy influx.

Researchers have developed a new concept for a heating control system with integrated weather data, which is currently being tested in three administrative buildings. The BINE Projektinfo brochure “When weather forecasts control the heating” (14/2011) introduces the system, the demonstration buildings and initial results.

Heat generated by the heating system should be more closely based on actual requirement. Until now, heating control systems have been based on specific time frames and rigid heating characteristic curves together with external temperature sensors. The new control concept combines a thermodynamic computer model with local weather forecast data. The computer model takes information into account concerned with the type of use, building physics, ventilation behaviour and the occupants’ desired temperature. These data are combined with data from the nearest weather station, and every six hours the supply temperature of the heating system is determined for the next three days through simulation and then automatically transmitted to the control module. Practical trials are currently underway in North Rhine-Westphalia, Germany, in the buildings of Landesbetrieb Straßenbau NRW in Gelsenkirchen, the NRW Ministry of Construction and Transport in Düsseldorf and the new Inland Revenue centre in Aachen.

Initial results confirm that the new system delivers greater convenience and saves energy. The control system is currently being developed further to meet the needs of small and large residential buildings.

About BINE Information Service
Energy research for practical applications
The BINE Information Service reports on energy research topics, such as new materials, systems and components, as well as innovative concepts and methods. The knowledge gained is incorporated into the implementation of new technologies in practice, because first-rate information provides a basis for pioneering decisions, whether in the planning of energy-optimised buildings, increasing the efficiency of industrial processes, or integrating renewable energy sources into existing systems.

Im Focus: The taming of the light screw

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.

The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...

Im Focus: Magnetic micro-boats

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.

The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...

Im Focus: Self-healing coating made of corn starch makes small scratches disappear through heat

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...

Im Focus: Stellar cartography

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...

Im Focus: Heading towards a tsunami of light

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
