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: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
