DESIGN AND MANAGEMENT OPTIONS FOR IMPROVING THE ENERGY PERFORMANCE OF HOUSING

Objectives:

The overall goal in DEMOHOUSE research and innovation is to reduce energy consumption for heating, cooling, ventilation and domestic hot water in renovation of housing by at least 30%, compared to the present standards. In addition, a decision support tool will be developed to assist project developers, housing corporations etc. with a viable implementation of the measures suggested. This includes a closer look at organizational and financial aspects of renovation.

The objectives in DEMOHOUSE are to:

  1. Develop minimum standards for sustainable renovation. There is a strong need for quality demands based on performance indicators and performance requirements to improve sustainable renovation. Several quality labels should be developed to distinguish several levels of energy saving in existing housing. The developed minimum standards for sustainable renovation can be coupled with the initiatives with regard to the formulation of a European energy Performance Directive.
  2. Develop a decision-making tool to improve sustainable renovation. To realize the desired sustainable development in Europe there is a strong need to develop a decision-making tool for sustainable renovation. Each organization concerned in the process of sustainable renovation can use the tool as an instrument for realizing optimized energy savings. Using this tool on large scale will make a real difference.
  3. Create long-time management structures to implement a life time orientation on sustainable renovation. The objective here is to create long-term management structures for guaranteed continuation of appropriate building maintenance approaches. A Life Time orientation is required: substantive energy saving can only be realized if the whole lifetime of the existing housing complex will be considered.
  4. Create long-time communication structures to guarantee ongoing dissemination and training concerning sustainable renovation. To realize the desired energy savings, dissemination and training is a precondition for success of the project. Permanent education is necessary to keep the awareness of good maintenance alive and may stimulate all the parties that are involved in housing to follow the examples.
  5. Develop, implement and demonstrate technological solutions to reduce energy consumption by minimal 30% compared to the present renovation standards. The overall goal in Demohouse is to reduce energy consumption for heating, cooling, ventilation and domestic hot water in renovation of housing by minimal 30%, compared to the present standards. To realize this objective innovations are necessary: Available renewable energy technologies are mainly developed for application in new houses. In case of existing housing there are a lot of additional boundaries for the application of these technologies, such as physical or social constraints. This means that these technologies have to be adapted before they can be applied in the renovations sector. The degree of realized energy saving will be measured by defining a demonstration project for each of the participating countries in the project.
  6. Develop a multidisciplinary approach of sustainable renovation to improve life quality. Sustainable renovation requires a multidisciplinary approach. Not only the technical solutions are important. Factors at organizational, social and financial level play an important role in realizing the objectives as well.


-Financial factors
There is a strong interaction between financial consequences and the implementation of technical solutions in existing housing. In order to remove the financial barriers to large-scale implementation of (new) renovation technologies new financing models will be developed and demonstrated.

-Organizational factors
Organizational barriers include the integration of communication and activities with regard to the many organizations and stakeholders involved in the process of sustainable renovation. Demohouse aims at finding solutions for these barriers by looking at new management systems to ensure effective large-scale rehabilitation of existing building stock.

-Social factors
Technological solutions should not only contribute to energy savings but also to the improvement of life quality including a healthy indoor climate. Technological solutions should be developed with the customer in mind.

The approach:

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.

Innovation in Demohouse can be described in three ways:

  • Renewable energy technologies that are available now can in most cases only be applied in newly built houses. In the case of existing housing stock there are additional (physical) boundaries for the application of these technologies. This means that these technologies have to be adapted before they can be applied in the renovations sector;
  • In addition to energy savings, health and social factors will be taken into consideration;
  • In addition technical barriers, organizational and financial barriers to the implementation of new technologies will be studied.

Summary:

Since the renewal of the existing building stock is about 2% per year there exists an enormous potential for improving energy savings and introduction of renewables in connection to the needs for rehabilitation of existing building areas in Europe. This will be even more relevant when the prospective new EU member states will join the EU. And with the right initiatives that could also be coupled with the Energy Performance Directive from the EC it could be possible to obtain a large impact on the high amounts of investments which will be necessary to improve the building stock in all European countries.

The aim of the proposed project is to develop minimum standards and recommendations in connection to healthy, cost effective, energy efficient and sustainable rehabilitation and to agree on actual quality agreements in this field. It is here the intention to realise a common action that can make a real difference in Europe.
It is aimed in the project to initiate important quality oriented R&D and demonstration activities concerning eco-rehabilitation and best available retrofitting techniques on a European scale by initiating R&D activities, which will later be tested in connection to real renovation projects. In fact, these are "full size prototype" tests, which can be monitored in a realistic environment and improved before the developed technologies are implemented on a larger scale.

Per participating country a Pilot project and a Reference project will be defined. The Pilot project will be the actual demonstration project, where the recommendations of the investigations and research will be implemented. The Reference project is a housing complex that has recently been renovated (or which is in the process of renovation) according to the usual local standards.

The selected complexes will be analysed on possibilities for improving the performance. Based on the state of the art within and outside the country concerned, solutions will be proposed. New solutions will be developed for the Pilot projects if existing solutions are not applicable.

The selected solutions will be implemented in the Pilot projects. Also new management approaches and new financing models will be developed and demonstrated. These management approaches will assess the sustainability aspect of future maintenance measures, whilst new financing models will help to ease implementation of energy efficiency measures in renovation processes.
