Project partners of RLT-Opt

The Fraunhofer Institute of Optronics, System Technologies and Image Exploitation IOSB in Karlsruhe develops systems and solutions in the business units Automation, Energy and Environment, Civil Security, Defense as well as Inspection and Visual Inspection with about 500 employees. IOSB's overarching core competence is systems theory and systems engineering: the ability to analyze, model, design and synthesize large, multidisciplinary systems. Modern concepts of control engineering and assistance modules based on machine learning methods have been developed and industrially realized at IOSB for many years.

Extensive preliminary work has been done in the field of building automation, e.g. in the projects:

• E-MonAut (Energy savings in existing buildings through comprehensive monitoring and automation concepts, FC 03ET1014A-D, 2011-2014)
• EffMon (Efficient monitoring in properties, FC 01LY1513A-G, 2016-2019)
• dynOpt-En (Energy manager for supply- and demand-based connection of energy sources, FC 03ETS001A, 2017-2020)
• ML4Heat project (FC 03ET1668A)

In the ML4Heat poject IOSB is implementing tools for the optimized operation of existing district heating networks based on machine learning methods.

IOSB has extensive expertise in the area of data analysis and machine learning. This has been developed and realized within projects in the area of monitoring and optimization of various processes (industrial production, drinking water networks, wind power plants).

Focal points in the project:

1. Developing algorithms, software tools for monitoring and optimization of ventilation and air conditioning systems (RLT-Opt project) based on machine learning and artificial intelligence.
2. Developing easy-to-use web platforms for monitoring and optimizing the operation of air handling systems.
3. Project coordination

BUILD.ING Consultants + Innovators GmbH (BCI) is an agile company of consulting engineers for energy and sustainability. BCI's service portfolio includes classical TGA planning, building certifications according to DGNB and BNB, energy performance certificates and energy inspections according to EnEV, building simulations, energy supply concepts as well as refurbishment concepts for technical facilities. In addition, BCI offers energy efficiency and energy management consulting, operational optimization as well as energy audits according to DIN EN 16247-1 and ISO 50001.

Preliminary work: BUILD.ING Consultants + Innovators GmbH (until 2017 BROCHIER Consulting + Innovators GmbH) has been involved in several BMWi-funded research projects in the field of energy-optimized construction since its foundation in 2013. In all projects, the focus is on increasing energy efficiency by optimizing plant operation with the lowest possible investment measures. Optimization strategies for building services equipment and the development of practical tools for identifying savings opportunities are the central topics that BCI addresses in its research projects.

In the project KaP "Kälteanlagen in der Praxis" (English: Refrigeration systems in practice; FC 03ET1066A, 03ET1350C, 03ETW012C), a simple tool for the optimization of refrigeration systems was developed. The multi-stage approach with initial assessment and detailed analysis can serve as a model for the design of the tool to be developed for the optimization of ventilation systems. The EnBeKa project (FC 03ET1119C, 03ET1449C) dealt with the improvement of monitoring and energetic optimization of commercial refrigeration systems. Here, attempts are being made to use largely automated processes and machine learning methods to make the monitoring of large plant inventories more efficient and to enable predictive service management. Similar approaches using artificial intelligence are also being pursued in the KMUplus project (FC 03ET1621A), in which energy management software is being developed that specifically addresses the needs of SMEs in the manufacturing sector and guides them to independent analysis and action.

In addition, the improvement of inventory analysis, monitoring and operational optimization of technical building systems has already been worked on in the two completed projects HoEff-CIM - Energy Efficient University - Campus Information Modeling (FKZ 03ET1176D) and IUPiTER - Interactive Implementation of Forecasts of Weather in Technical Building Equipment for Energy-Optimized Room Conditioning (FKZ 03ET1033C).

Focal points in the project:

• Analysis of monitoring data
• Identification of recurring topics from the energetic inspection
• Monitoring of energy parameters
• Continuous monitoring of characteristic values for energy inspection
• Condition monitoring (comfort, optimal operating points, monitoring KPI)
• Strategies for automated detection of frequent faults
  possible applications of artificial intelligence
• Description of typical application cases (use cases)
  Specifications for concrete implementation (IT specifications)

IBDM GmbH is a small medium-sized company, which was founded in 1997 in Ottobrunn near Munich. From the beginning, the focus was on increasing the efficiency of air handling systems. IBDM GmbH works with about 20 freelancers and permanent employees all over Europe.
Preliminary work:

Over the past 22 years, more than 10,000 AHU heating-cooling systems have been metrologically inspected and put into operation. The energetic inspection according to DIN SPEC 15240 is a part of the service offer for the optimization of TGA plants.

IBDM GmbH has developed its own tool for analyzing TGA systems. The customers come predominantly from the economy and trade: Insurance companies, public utilities, industrial enterprises, housing associations, ...

Based on many years of experience, it can be deduced today that every HVAC system has an energy saving potential of at least 20%. A decisive aspect for increasing energy efficiency lies in the holistic consideration of energy systems: only the integral approach leads to success.

Focal points in the project:

• Contribution of practical experience in energy optimization
• Development of new mobile measurement techniques for the evaluation of air handling systems
• Localization and evaluation of saving potentials in demonstrator properties
