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

Solar XXI, office building, Portugal.

Architects: Pedro Cabrito, Isabel Diniz

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.
