Building Automation -Simulation-Supported Automation for Sustainable Air-Conditioning of Buildings in summer

Background and Goals

The project develops and tests procedures for the automatic, weather-dependent control of building technology. In the building envelope, for example, the approaches include sun protection and ventilation flaps, and in building technology, they include ventilation and air conditioning systems, thermal and electric cooling, and lighting. With the help of software-based simulations, strategies for low-energy climate conditioning of buildings in the summer months will be designed and evaluated.

Manufacturers of building automation systems and building management instruments are integrated in the project The first application will take place in commercial buildings.

The aim of the research project is the development, implementation and evaluation of automated control procedures for technical building services and building operation. The project calls on climatic models and forecast tools available online, and incorporates this information intelligently in the procedures. To this end, the energy saving possibilities of the building envelope are to be examined (e.g. mechanical) on the one hand, and on the other, those of the building technology (through adaptive control). The software tools developed for this purpose are made available in standard libraries for different simulation platforms.

Steps in the process of adaptation to climate change

Step 1: Understand and describe climate change

Parameter (climate signals)
  • Heat waves
  • Higher average temperatures

Step 2a: Identify and assess risks - climate effects and impact

Approach and results 

Due to the extreme summer temperatures, more and more structural and technical conversions are necessary to ensure comfortable ambient temperature conditions in summer. However, existing building automation solutions are often problematic and inadequate. The integration of the solutions into the building automation system often proves to be inefficient. With the developed software tools, an efficient integration of retrofits and conversions in the existing control environment is guaranteed. This results in a sustainable reduction of energy costs for building operation, for existing buildings as well as new constructions.

Step 2b: Identify and assess risks - Vulnerability, risks and chances

Urgency and priorization of adaptation needs 

The dynamic building simulation tools previously only used for planning will be used in daily operation in existing buildings. The incorporation of forecasting and simulation tools in building control systems results in an intelligent management system and the best possible interaction between the building technology components in each case.

Step 3: Develop and compare measures

Measures and/or strategies 

The dynamic building simulation tools previously only used for planning will be used in daily operation in existing buildings. The incorporation of forecasting and simulation tools in building control systems results in an intelligent management system and the best possible interaction between the building technology components in each case.
