Goals and key aspects of the KENWO project

Goals of the research and development project KENWO were: • The further the introduction specific, integrated and optimized energy concepts

in applications

• The implementation of energy concepts using a sustainable cost efficient energy management system for monitoring

• Evaluation of several aspects of the concept using a number of real buildings and gaining experience for real-world applications

Monitoring• Measuring, documentation and analysis

of usage based data• Controlling and observing of costs for

energy consumption• Early detection of undesirable

developments and disruptions as well as identifying risks

• Taking well aimed measures

Assesment and recommended measures for:

•Warm water provision•Hydraulic inefficiencies •Taking advantage of the upper heating value effect•Cycle operation of the heater•Reviewing of connected load and rating•Monitoring of generator usage•Night set back•Heating limit / summer operation•Outliers and artifacts

Web portal with online data for the buildings of the project

• Consumption data for building on daily, weekly and monthly basis

• Benchmarking / review (internal and external)

• Collection of all relevant information on building(i.e. energy performance certificate, energy report, etc.)



11

Results for the district Ludwigslust

• Saving of up to 19% possible with improved operation (heating interruption, system temperatures, flowrate,…)

• Savings with optimized contracts (i.e. changing connected load of long distance heating)

• Optimization of costs for investments and follow-up cost for refitting measures

• Improvement of comfort due to hydraulic adjustment and regulation of heating

• Increasing of reliability though transparency of systems (condition, maintenance, calibration of the meters, etc. )



12

ECO Region in the district of Ludwigslust

Planned project:

„continuous monitoring with automated fault detection in office buildings in the district of Ludwigslust“

• Expansion of the continuous monitoring

• Implementation of automated fault detection and error report management



13


Planned project:


• Expansion of continuous monitoring

– Expansion of the existing monitoring by adding addition system temperatures, operation values and sub meters

– Integration of recorded data into Software for automated processing for visualization, creation of statistics and preprocessing



14


Planned project:


• Implementation of an automated fault detection and error reporting management

– Development of rule based models for automated fault detection of the monitored systems

– Implementation and testing of feasibility for other objects
