ICT platform for holistic energy efficiency simulation and life cycle management of public use facilities

Start date: 01.09.2010

Duration: 40 months

Coordinator: Technische Universitaet Dresden

Budget: 5.1 M€


HESMOS was a 40-month European FP7 industry-driven project particularly directed to the demand of PPP and BOT providers for an integrative view of energy efficiency and cost balance over the building lifecycle, bringing together, via integrated IT tools and a collaboration environment, architects, building services engineers, facility operators, public authorities, tenants and owners.

In the context of the thematic priority programme “ICT for energy-efficient buildings and spaces of public use”, HESMOS anticipated that especially public use facilities developed as PPP projects can play a leading role in energy efficiency and sustainability as they provide the advantage that design, construction and operation can be seen as a whole thereby leading to much stronger industry interest in integrated solutions and more reliable decision-making than practiced today.

In accordance with that, the major objectives of the project were:

  • To provide advanced simulation capabilities to decision makers in the whole life-cycle of buildings, taking into account energy savings, investment and life-cycle costs
  • To connect CAD, FM and eeTools (energy efficiency tools) in order to enhance building industry actor's ee-competences
  • To close the gap between Building Information Modelling (BIM) and Building Automation Systems (BAS) so that decisions can be made economically (energy and cost related) in all life-cycle phases
  • To integrate various information resources thereby extending current Building Information Modelling (BIM) to an energy extended multi-model framework (eeBIM)
  • To provide a new methodology for energy and emissions saving in BOT and PPP projects of public use facilities using BIM-based methods of working, and evaluate the developed methodology in performed real-life pilot projects.

The VISION of HESMOS was that each architect and each facility manager should be able to do in depth energy analyse and profound energy life cycle cost estimation of any of his buildings on the basis of IFC-BIM.

The MISSION of HESMOS was to design and develop a holistic ICT platform with a sound BIM interoperability method to provide integration of any BIM compliant CAD, energy analysis tools and sensor networks and using appropriate mapping algorithms, filter functions and visual representation techniques.

List of achievements


(1) An open platform supporting flexible simulation and design cycles featuring life-cycle energy simulation and management services, web-based BIM navigation, and result evaluation via eKPIs to enable more efficient team decision-making

(2) Multi-model methodology and tools extending standard BIM (ISO 16739) to a multi-model energy-extended BIM framework, eeBIM

(3) A novel semantic and intelligent Virtual Energy Lab, IVEL, which is fully based IFC-BIM and the developed eeBIM interoperability framework including BIM/BAS interoperability and FM / Energy Simulation Tools integration

(4) IDM / MVD improvement by a developed by HESMOS easier to use guideline for practice.

Additionally, HESMOS enables the presentation of sensor data on the virtual building model and compares them to thermal simulation results to identify optimization potentials.

Two tools developed in HESMOS have already reached Technology Readiness Level (TLR) 7 or higher. These tools are: Granlund Manager Metrix, exploiting BIM based HESMOS methods for performance management metrics, and WebRoomEx, the eeBIM based Facility Management application developed in the frames of the project. Both tools are available directly from Granlund or via Granlund, in conjunction with HESMOS IVEL freeware.
