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

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.

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 yesterdayWorkshop: to discuss the findings of A&B

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.

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.

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.

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

Subtask E

• 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

On going/plan

• 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.

International Workshops
