In many buildings, annual energy savings of between 10% and 15% can be achieved by implementing relatively simple measures such as high efficiency fluorescent lights and motors, and heating-cooling system upgrades.

Then, on heat, natural gas is the largest percentage, both directly and indirectly through electricity, because natural gas used for electricity can then be used in heat applications.

That exclusion should not restrict the possibility of using the ERDF to support activities that are not listed in Annex I to Directive 2003/87/EC even if those activities are implemented by the same economic operators, and include activities such as energy efficiency investments in district heating networks, smart energy distribution, storage and transmission systems and measures aimed at reducing air pollution, even if one of the indirect effects of such activities is the reduction of greenhouse gas emissions, or if they are listed in the national plan referred to in Directive 2003/87/EC.

All processes directly or indirectly linked to the process units coke ovens, HS/NH incineration, coal preheating (defreezing), coke gas extractor, desulphurisation unit, distillation unit, steam generation plant, pressure control in batteries, biological water treatment, miscellaneous heating of by-products and hydrogen separator are included.

(ii)in the case of heat pump installers: training as a plumber or refrigeration engineer and have basic electrical and plumbing skills (cutting pipe, soldering pipe joints, gluing pipe joints, lagging, sealing fittings, testing for leaks and installation of heating or cooling systems) as a prerequisite.
