Energy-Efficient Building Operation: Monitoring Platform MONDAS Identifies Energy-Saving Potential

16.01.2017

Through optimized operation management, up to 30 % of building energy consumption could be saved. Even low-cost investment measures could result in optimization and significant reduction of costs. In order to save energy, a detailed analysis of the building operation is necessary. For this purpose, Fraunhofer ISE developed the energy monitoring platform MONDAS, which provides all components necessary for collecting, saving, processing and visualizing relevant time-series data regarding building operation. The platform successfully pools software modules to a high-performance overall system. It will be presented at the BAU 2017 trade fair.

Through continuous and automated supervision of the operation of building services, significant energy savings can be reached. Optimization takes economical aspects into account and focuses on energy costs, thermal comfort and effective energy and facility management. Often even inexpensive measures have a significant effect on energy efficiency and building operation costs.

This especially applies for existing offices and commercial buildings, where for instance often only minimal changes in the parameters of the Building Automation System are necessary to improve the building operation. “It is crucial for the building operators to evaluate large amounts of data with an efficient and comprehensive software, in order to quickly identify energy saving potentials and to organize corrective measures”, explains Nicolas Réhault, Head of Group Building Performance Optimization at Fraunhofer ISE.

“With the energy monitoring platform MONDAS, we provide this target group with a high-performance tool.” The energy monitoring platform was developed by Fraunhofer ISE and PSE AG, and is available from both partners upon request.

Data collection

The data collection module of MONDAS is a flexible interface for different measuring devices and protocols regarding building operation. The basis for this is a fully configurable, expandable basic implementation that connects to the existing Building Automation and Management Systems over protocols like Modbus TCP, ModbUS RTU, CANopen, BACnet, M-Bus and EIB/KNX, as well as user-specific protocols.

Data management

MONDAS uses the HDF5-Format to store the data collected. This enables access that is up to 100 times faster than in SQL-based relational databases. As a result, even very large data records are highly available for analysis algorithms and visualizations. Furthermore, several databases can be connected to a cluster of data modules via a data protocol. With every time series metadata is saved that describes for instance the sensor or actuator location or the sensor type like e. g. a temperature or pressure sensor. Thereby, the metadata represents the basis for further automated processing steps like e. g Fault Detection and Diagnostics.

Standardized filtering functions

A further key component of the MONDAS platform includes standardized filtering functions that can be interconnected to complex calculations. The standard filters include simple tasks, such as recognition and interpolation of data gaps, comparison of different data sets, as well as complex methods for identification of certain data patterns and correlations. This methodical approach forms the basis for development of data analysis algorithms.

Automatic Fault Detection and Diagnostics

Based on the basic components of MONDAS, Fraunhofer ISE has developed different algorithms for the automated supervision of the energy building operation. They enable the automatic detection and identification of errors and suboptimal states in the operation of building services like heating, ventilation and air conditioning systems. They also provide important insights for energy and facility managers to organize corrective measures. The developed algorithms include a rule-based system based on expert knowledge as well as machine learning methods like e. g. clustering or qualitative models.

Data visualization and analysis results

The web-based data visualization of MONDAS offers a multitude of display options to the user who can configure and structure his interface according to his needs. Visualization options include simple line and bar charts, as well as relational data charts and color gradient charts that make statistical relationships quick and easy to comprehend. Display and parametrization views (Widgets), for example descriptions or equipment overviews, can be arranged in different views. The views allow hierarchical subdivisions, enabling structuring according to the building, equipment or energy flow structure and thus displaying adequate information to support energy and facility management tasks.

Fraunhofer ISE will be presenting its energy monitoring platform, MONDAS, at the BAU trade fair from 16 to 21 January 2017 in Munich. Please visit us at the Fraunhofer-Allianz BAU stand in hall C2, stand 538.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
