The goal of improving energy savings by at least 30% will be measured by defining a Pilot project and a Reference project in each of the participating countries. The Pilot project will be the actual demonstration project, where the recommendations of the investigations will be implemented. The Reference project is a housing complex that has recently been renovated or will be renovated in the near future according to existing local and national standards.

The main structure of the project is summarised by the Figure below:

Schematic overview of the project structure.

As Is - Reference Projects

Stage 1: Barriers

Basically, the project starts with identification, description and analysis of the reference projects, one per participating country. The reference project is a housing project that is going to be renovated within the time frame of the project. Within the renovation processes, the reference projects will usually be adapted to the energy performance standards that are in force.

By selecting a reference project in each of the participating countries, the barriers for sustainable, energy conscious renovation can be defined as a basis for generation of solutions. Case studies of reference buildings regarding design and the environmental impact of the materials and technologies are a good start off point realizing the objectives of Demohouse. This includes whole life analysis of the reference projects regarding maintenance, repair and demolition.

At first, the state of art for each of the participating countries regarding energy and sustainable design will be assessed, including the principles of the available subsidy systems. Next, the guidelines for the measurement of energy consumption and environmental impact of the materials and technologies will be established. This involves a closer look at the organizational aspects of renovation nowadays including social and economic implications.

The next step concerns the testing and evaluation of reference buildings via the above guidelines, which leads to the determination of the energy consumption and socio-economic impacts. Finally, there will be an evaluation of the possible disadvantages on secondary issues such as fire safety, acoustics etc.

Stage 2: Best Practice

Generation of Solutions
In this stage an inventory will be made of possible existing solutions, both technical and organisational. Important here is the cross fertilisation between the particpating countries. Knowing about the technical, social, financial and organizational factors concerning the current state of the art in renovations, a new phase in the project starts. The basic idea here is to develop a new kind of quality and value oriented design process in connection to renovation projects. Important in this stage is the cross fertilisation between the particpating countries.Every country has its own input in developing a catalogue, which is about the 'best available technologies' inclusive innovative technologies. The main goal is to reach an agreement concerning performance indicators, performance requirements and check systems for each available technology. This will serve as a basis of the aim of defining minimum standards for eco efficient renovation in different regions in Europe. Concerning all technologies an overview will be made on the matureness in different countries so good solutions can be transferred to other countries for demonstration and if there is a need for initial tests of technologies this will be initiated prior to demonstration.

The most optimal energy saving and renewable energy packages will be identified by calculation of life cycle costs in an optimization process. Evaluation of the most optimal technologies can be made by calculations of CO2 emission reduction per Euro invested.

Socio-economic solutions and organizational designs
Beside the technical aspects concerning the improvement of energy savings in renovation, management factors also play an important role. Developing new management strategies to overcome organizational and economic barriers for implementation of energy efficient and sustainable renovation technologies is one of the main objectives.

Stage 3: Selection of Solutions

Apart from possible existing solutions, new solutions will be generated in this stage. Solutions will be ranked according to:

  • Effectiveness: CO2 reduction per Euro invested;
  • CO2 reduction related to sustainability;
  • Applicability of the techniques/solutions without adaptations;
  • Contribution to the increase of renewable energy.

To guarantee an optimum of exchange and sharing of knowledge, teams of experts from different participating countries will carry out analyses of the reference projects.

Next, the solutions will be integrated into a technical design for the pilot projects. Selection and evaluation tools will be developed to make a selection of existing and new solutions. Also suggestions for a new management approach will be developed. The expected solutions focus on strategies to overcome socio-economic barriers and on management protocols during the life cycle of the pilot projects.

To Be - Pilot Projects

Stage 4: Implementation of solutions

The generated solutions will be implemented in national Pilot projects. In these demonstration projects several recommendations of the investigations originating from the reference projects will be tested in the field. To compare both projects on relevant issues such as energy consumption, comfort, maintenance and sustainability monitoring and analysis is essential. This implicates the need for definition of parameters for assessing the energy and sustainability performance.

In the final stage a decision support tool will be designed that can help house owners, architects, construction companies, consultants and others to develop renovation and maintenance plans in the housing sector that perform substantially better than usual (taking the local energy performance standards as a point of departure). Ongoing dissemination and training concerning sustainable renovation has to be guaranteed as well.
