• 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
• 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.
• 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
– Identification of obstacles to effective storage techniques.
The final report was presented yesterday
Workshop: to discuss the findings of A&B
• 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.
• 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.
• 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.
• 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

• Identify technologies and applications needed in the long-term to achieve ultra low energy building objectives and develop typical
Sustainable Energy Storage Designs
Work is under progress
• Determination of thermal behaviour of new material/component (measuring technique),
• Validated calculations and LCA tools for assessment of material/component,
• What is the affects of this technology on other aspects e.g. IAQ, fire.
