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

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).
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

Task 40/Annex 52
Advanced Lighting Solutions for
Retrofitting Buildings – Task 50
Electric lighting energy demand is forecasted to grow from now 2900 TWh to
4250 TWh in 2030. 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.
