Security for estimating the consumption

Energy management systems are designed to reduce the energy consumption in buildings. A design procedure for such control tools is currently being developed in the “enerMAT” project. This is used during the project development stage. This is the phase in which decisions are made about investment and operating costs, energy savings and comfort.

Energy management systems provide joint control and automation of the air conditioning technology and lighting with energy storage systems and sources. By 2015 the “enerMAT” project partners want to develop a procedure with which an energy management system can be developed for all buildings installations. In the research project, the EAS Design Automation Division at the Fraunhofer Institute for Integrated Circuits IIS is working together with four medium-sized companies from Saxony.

It is already possible to automatically control individual components such as the heating and ventilation. However, considerably more energy can be saved if the various devices are already matched with one another and the respective space use during the planning phase. For this purpose, the researchers are integrating not just the loads but also the energy generators and storage systems within the control system.

Lower costs through new design environment and methodology

The project partners are developing a methodology and design environment for energy-efficient building control. This is aimed at securing the planning, optimisation, commissioning and operation of complex systems. The researchers are hoping to considerably reduce the planning and commissioning costs. Ultimately the aim is to remove the hurdles for marketing and using integrated management systems for manufacturers, homeowners and tenants. In particular, the project partners want to considerably reduce the high development costs for automation solutions in the highest energy efficiency class to EN15232 with a view to making further energy savings.

After a year of working on the project, the requirement definitions for the design system are about to be concluded. The project development work can now begin for the demonstration plants. A plant for controlling the air-conditioning, lighting and shading in a conference room in an energy-efficient manner is being assembled at the EAS.

The German Federal Ministry of Economics and Technology is subsidising the “enerMAT” research project with around 4.5 million euros. The involvement of medium-sized companies in the research consortium is intended to facilitate the development of prototypes and ensure rapid market maturity.

These partners are taking part:

  • NSC is able to call on its experience in conceiving and realising building-based automation solutions as well as its experience gained in a project for an energy-independent home in Lehrte.
  • The FASA construction company is supporting NSC in specifying structural and construction process-based requirements for the energy flow-optimised overall concept.
  • Provedo is designing the network and software for implementing complex distributed control solutions.
  • Together with the EAS research institute, ITI, a medium-sized provider of simulation software and modelling services, is providing the methodical knowledge about model development, description languages, simulations, verification and optimisation.
