The overall objective of the Annex was to promote the rational use of energy by means of low valued and environmentally sustainable energy sources. The overall objective was divided into three goals:
- To investigate the potentials for replacing high valued energy (e.g. fossil fuels and electricity) by low valued energy sources and to assess the impact on global resources and the environment.
- To assess existing technologies and components for low exergy heating and cooling in buildings, to enhance the development of new technologies, and to provide the necessary tools for analysis and evaluation of low exergy systems.
- To work out strategic means for the introduction of low exergy solutions in buildings by case studies, design tools and guildelines.
The first preparation phase was held in March 1999 to outline the following objectives:
To improve the understanding of possible inputs/state-of-the-art in the countries
To improve the understanding of expected outputs / objectives of the countries
To identify the main tasks which the Annex should focus on
To identify the results which should be achieved
To identify the task distribution amoung the countries according to their main interests and experiences
Participants: Canada, Denmark, Finland, France, Germany, Italy, Japan, The Netherlands, Norway, Sweden
