Market Transformation Towards Nearly Zero Energy Buildings Through Widespread Use of Integrated Energy Design (MaTrID)

Download PDFDownload PDF
The IEE-project MaTrID – market transformation towards nearly zero energy buildings through widespread use of integrated energy design – started in June 2012 and ended in December 2014. The project aimed to support the implementation of the Directive on the Energy Performance of Buildings. In this context the building design phase is of particular importance. Integrated Design (ID) in general is the most appropriate approach to reduce the complexity of the design process and to facilitate the interactions between the members of the design team. ID allows them to provide the best solution for the whole building. It is not limited to energy efficiency and goes beyond this issue. The greatest benefits are provided only if applied in the earliest stages of the project, when changes to the design are still easy to implement.


  • A general understanding on the advantages and requirements of IED at the side of real estate developers and building owners. 160 seminars with stakeholders and 4 expert training sessions were carried out.
  • More than 1 mio. stakeholders could be reached.
  • An improved know-how basis on IED. Application of IED requires practical knowhow on the developers’ side as well as on the designers’ side. Therefore a European Integrated Design Tool-Kit was developed. The tool-kit consists of i) an ID Process Guide, ii) a Clients Summary, iii) a Tenants Summary and iv) a module on Scope of services and remuneration models. 
  • Successfully tested 24 pilot projects with about 260,000 m². The practical implementation of IED on a large scale, thus, setting best practice examples across Europe, which can be easily copied and multiplied.
  • General acknowledgement of IED beyond the limits of the participating countries and project period.
  • Implementation of the GreenBuilding Integrated Design Award 2014. The European GreenBuilding Integrated Design Award intended to provide European visibility to outstanding integrated design processes. With this award the importance for the application of integrated design was highlighted.
  • Additional renewable energy: 0.7 Mtoe/year between 2013-2020.
  • Primary Energy savings: 2.3 Mtoe/year between 2013-2020.
  • Reduction of GHG-emissions: 1.2 Mt CO2e/year between 2013-2020.

Lessons learned

  • The design of NZEB requires an interdisciplinary approach already in the design phase. Specifications from involved architects, construction engineers and facade designers are required. For this reason, the early introduction of a design team is compulsory for the design of NZEBs. In this context the building design phase is of particular importance.
  • ID is a valuable assisting approach to reduce the complexity of the design process to identify benefits and drawbacks of alternative design concepts. ID also allows decision makers to act based on transparent facts. Only if ID is applied from the very beginning of the design phase it can assumed that a cost-effective solution for NZEB can be identified, as only at the early design phases changes of the general design concept can be implemented at low cost. The application of ID is part of the best way towards the intended NZEB at low cost.
  • To succeed with an ID process, it is important that overall energy issues are discussed already in the initial planning phase. It is important that the client understands the advantages of using the ID process in conjunction with planning.
  • Feedback from a participating pilot project company:
    • ID process must be communicated from the beginning to all partners, continuously.
    • Changes must be communicated to the tenant and the occupants.
    • There must be a contact person on tenant's side to communicate all informations and needs during the whole process to the occupants … and vice versa.
