3. Subtask A Coordinated national reviews of energy storage use in energy efficient buildings To share the information among the members and to “inform” the members about all the considered systems To give the actual picture of ES use in each country, design concepts used and practical results, To highlight limitations and needs for new research activities. Task has been completed

5. Feedback Improve the knowledge of the storage material has been identified as the most important information to improve the technology. Optimization is necessary for the control, sizing, system integration and modification, fundamental and applied research is needed to remove many hurdles in the large scale applications of these technologies.

6. Subtask B Collaborative evaluation of energy storage usage and proposed efficient systems based on Subtask A and other Annex results. – Evaluation and inclusion of related finding from other IEA activities – Identification of obstacles to effective storage techniques. The final report was presented yesterday Workshop: to discuss the findings of A&B

7. Subtask C Development of Sustainable Energy Storage Designs for a variety of Ultra-low energy building thermal and phase change materials options. – Conceptual design of ultra-low energy building types with energy storage, – Case studies A number of case studies have been performed.

8. Work under way Development of improved tools for modeling, simulation and optimization for integration in comprehensive building simulation programs, – Develop a numerical model for PCM integrated walls (to be integrated with TRNSYS) and validated with field data from task D, – Perform detailed simulation to show the benefits of TES application in ultra low energy building. Only one case study should be proposed for all participants.

9. Subtask D Apply, monitor and evaluate demonstrations of these Designs in a number of countries and climates – To monitor experimental/prototype systems with Energy Storage for model validation – To monitor real buildings (already built or under construction) with Energy Storage Systems, Data for model validation, Comparison of efficiency and performance of technologies A comprehensive data base has been developed.

10. On Going Experiments PCM passive cooling with conventional brick, alveolar brick and concrete walls PCM wallboards Ventilated facade with PCM Ventilated façade with concrete Heat pump with PCM tanks Water+PCM tanks for domestic hot water PCM packed bed for cold storage
