Fault Detection & Diagnosis

Module ready for use
by Fraunhofer ISE

The Fault Detection and Diagnosis (FDD) Module helps Facility Managers and other technical personel who wants to get a quick yet deep overview of their managed buildings operation by reducing the effort on accessing and displaying their measured data and enabling them to utilize rich visualization capabilities and additional data sources like Fault Detection and Diagnostics (FDD). It is based on the powerfull mondas® platform.

The main purpose of this module is to enable decision support for the operational management of the building by providing an overview as well as detailed information on the energy operation of buildings and building services like e.g. heating, ventilation and air conditioning systems, lighting etc. Also if avaiable it provides clear and targeted energy performance information on the basis of outputs from FDD algorithms as well as forecast energy consumption datasets from the building energy simulation models.

The data visualization module for building occupants is aimed to help reduce de performance gap by:

  • Giving access to the data collected on the building to the occupants
  • Making the data understandable and easy to read for a large audience (non-technical profiles)
  • Influencing them in their daily interaction with the building by providing indicators that they can well apprehend

BIM Viewer / 3D Visualization Module Zutec Dimensions

Module ready for use
by Zutec

Dimensions is an application that can show real time data from a building on the 3D model providing an interactive interface to the current status of the building. This allows facility managers to quickly identify potential problems to take the neccesary actions. This is aided by any data associated with the model. eg. Maintanance manuals or warranty information.

Energy control

Energy Management

Module ready for use
by Enerit

Energy Management is a concern when not considered necessary or not accurately performed, but it becomes core business when it is managed in a systematic way. Energy Management is a resource, simple, secure, clean and economical while maintaining adequate level of services with the minimum requirement of energy. The Energy Management module supports Organizations who aim to have a systematic way to reduce year-by-year energy costs, and the capability of supporting all aspects of the Energy Management System (EnMS), in compliance to the ISO 50001 international standard.

The Service as a Software (SaaS) has a unique energy management functionality :

  • energy review process visualized through integrated Sankey energy flow diagrams, tables and graphs
  • identifying baselines and Energy Performance Indicators (EnPIs)
  • capturing & prioritizing improvement opportunities for easy decision-making
  • automated assignment of actions with target dates & reminders to energy team members
  • management reports including energy and action status dashboard as well as all the management system capability
  • document management
  • audit & non-conformance management
  • meetings & management review

“Within an ISO 50001 EnMS and the SaaS, the process is identified and communicated to the stakeholders, e.g. the operators and the energy managers. Through the analysis of the energy data, deviations will be highlighted and corrective actions can be implemented to bring the system under control and make sure it does not happen again (through training, updated procedures communicated to the operators and the energy managers etc.).”

Load Forecasting

Module ready for use
by Universitat of Girona

An accurate estimation of future energy consumption helps energy/facility managers to have a better energy control budget or decide how to schedule energy intensive sytems. Also, they allow to calculate savings when energy efficiency measurements are implemented. This module provides load forecasting for different horizon times and using different methodologies, which allows its use for a large set of builiding types.

Module under developments
by Fraunhofer ISE

The GapReasoner Module helps Energy Managers who want to assess the energy performance of a building by countering the lack of a meaningful reference and providing a list of possible reasons of a performance gap.
It relies on uncertainty analysis (UA) and sensitivity analysis (SA) of building performance simulation. The module provides the possibility to run simulation models with a set of uncertain input parameters (e.g. building parameters, climate conditions, occupancy). The simulation results (e.g. energy consumption) are represented by probability distributions, according to the input probability distributions of the uncertain parameters.

Making use of uncertainty analysis methods gives the user a more reliable simulation result, as input uncertainties are taken into account.

Additionally, the module provides methods for sensitivity analysis, which allows for determining the impact of varying input parameters on the output variation. This funcionality is used to provide a list of most influencial parameters in case of a detected performance gap.

The module works as a backend service and provides results data to other BEMSever modules (like the FM Display Module).

ModSCO – Reduced Order Models to tackle the performance gap

Module under developments
by National University of Ireland Galway

ModSCO is an application that provides engineers an easy interface to produce Reduced Order Models (ROM) underpinned by MODELICA ® language without the hassle of learning complicated simulation software. Energy managers can use the models generated by ModSCO for a variety of energy related applications such baselining or assessment of energy savings. ModSCO is integrated with BEMServer so it can retrieve relevant static data and performance variables like energy consumption from different tooms or buildings. ModSCO is also capable of connecting with other BEMServer services like CALIBRO, FDD-PCA or ENERIT Energy Management module to provided added value services using your models.

Indoor Environmental Quality

Module ready for use
by University of Strathclyde

This module provides simulation-based assessments of thermal comfort, visual comfort and indoor air quality. These assessments are provided for each user workstation, with outcomes indicating locations and times when performance standards are not met. Application of the module requires the a priori construction of a high-resolution model of the estate, in whole or part.

Energy behaviour

ENIXO – Semantic-driven Behaviour Simulation

Module ready for use
by EGE University

Enixo, the semantic driven energy behavior module, provides energy controlling and forecasting in buildings, offers a benchmarking tool for energy efficiency improvement, whilst keeping its special focus on indoor air quality and users’ comfort. In particular, the tool detects bad indoor air quality, checks its compliance with the standards and identifies occupant discomfort states in buildings.

The tool provides practical solutions including :

  • Detect abnormal energy consumption and its location
  • Monitor energy consumption and compare to the predicted consumption
  • Compare energy performance between floors, zones, spaces etc.
  • Detect user discomfort state and bad indoor quality
  • Generate recommendations towards energy efficiency and user comfort


Module ready for use

Energy systems are more and more optimized in buildings… yet, what about human behavior?

What about :

  • lights and heating systems left open  in unoccupied spaces or during non work hours?
  • fast- in the morning- and late- in the evening-heating/ cooling of spaces?
  • lighting systems used during daylight conditions?
  • space overheating or over-cooling due to improper
  • setting of the thermostats?
  • windows left unintentionally open?
  • blinds that block the sun in the winter and allow it through in the summer?

There are some of the most common behavioral issues we encounter in buildings.
WT – BeHave, is a Wireless Things add-on that lets you trace such events, calculate their energy impact and send out notifications to users or managers of spaces.
It even lets you set up control schemes based on behavioral events. Human behavior is considered a most untapped opportunity for energy efficiency in buildings. WT BeHave uses high innovation and low cost technology to tap into it.
