They fullfil the requirement, if they cover • 15% or more of their heat demand by solar thermal energy or • 50% or more of their heat demand by solid biomass (e.g. Pellets), liquid biomass (e.g. bio heating oil) or heating pumps • 30% or more of their heat demand by biogas used in combined heat and power units – In case of solar thermal, the requirement is fulfilled if • 0.04 m² collector area is installed per m² living area (1/2 family residential homes) • 0.03 m² collector area is installed per m² living area (other residential buildings) Status Solar Thermal Energy, March 24th, Cairo 31
  • Important aspects which influences ST markets … and differs a lot from market to market• Climate conditions• Technologies – Conventional heating equipment – Quality requirements• Architecture/Design• Financial aspects – Purchasing power – Subsidy schemes – Energy costs• Market structure – Distribution paths – Installers: education, ability to sell solar• Environmental awareness of the people• … Status Solar Thermal Energy, March 24th, Cairo 32
  • Conclusions and outlook• Europe is the second largest Solar Thermal market worldwide with about 4 Mio m² collector area installed annually in 2008• Europe and especially Austria and Germany are leading countries worldwide regarding solar thermal energy components and systems technology• The European solar thermal industry and R&C sector build up a Renewable Heating & Cooling Technology Platform and aims to cover 50% of the overall heat demand by 2030 with solar thermal energy• In order to develop a solar thermal market, all aspects must be developed in parallel: industry, public awareness, subsidies, products, installation capacity• We would love to work together to increase the share of solar thermal energy in the MENA region as well Status Solar Thermal Energy, March 24th, Cairo 33
