11 ENERGY STORAGE THE KEY ISSUE Task 42/24 Joint Task between Solar Heating and Cooling (SHC) and Energy Conservation through Energy Storage (ECES)

12 4 principles for Heat Storage Sensible heat - principle: heat capacity - reservoirs, aquifers, ground/soil Latent heat - principle: phase change (melting, evaporation) - water, organic and inorganic PCMs Sorption heat and Chemical heat - principle: physical (adhesion) or chemical bond (reaction enthalpy) - adsorption and absorption and chemical reactions h=stored heat h h T T T

13 Development Stages of TES Technologies Water (sensible) PCM (latent) Sorption TCM (chemical) Market mature Demonstration Development Research CHARGE + heat + STORE DISCHARGE + + heat

14 Development fields Materials - improve performance (capacity, power) - reduce costs (basic material, production technology) Components - heat exchangers - mass transport - sensoring, control Systems - Integration - control

36 Task 51: Solar Energy in Urban Planning May 2013 April 2017 NEW! Main objectives Provide support to urban planners, authorities and architects to achieve urban areas and eventually whole cities with architecturally integrated solar energy solutions (active and passive), highly contributing to cities with a large fraction of renewable energy supply. Develop processes, methods and tools capable of assisting cities in developing a long term urban energy strategy. Heritage and aesthetic issues will be taken into account. Prepare for and strengthen education at universities on solar energy in urban planning, by testing and developing teaching material. The material will also be useful for post graduate courses and continuing professional development (CPD).

37 Case studies, Buildings Selected case studies from different countries will be presented Selection based on: - Architectural quality - Energy performance With a diversity of building type and location Solar XXI, office building, Portugal. Architects: Pedro Cabrito, Isabel Diniz

39 Net Zero Energy Buildings Task 40/Annex 52

40 Advanced Lighting Solutions for Retrofitting Buildings Task 50 Electric lighting energy demand is forecasted to grow from now 2900 TWh to 4250 TWh in Saving potentials mainly lie in retrofitting the building stock. The Subtask Activities Market and Policies, Daylighting and Electric Lighting Solutions, Methods and Tools and Case Studies will support allocating these potentials by enabling building owners to benchmark and compare their buildings, to get cost indications and hereby prepare and initiate retrofit decisions; authorities to initiate and / or improve regulations, incentive programs (loan, tax liability based incentives, ), certification procedures designers and consultants to get validated design solutions, to employ appropriate technologies and to benefit from tailored design tools lighting and façade industry to adapt products and services according to market figures, identified market barriers and opportunities, developed retrofit strategies and evolving new technologies.
