Exhaust air heat recovery, on-demand control of ventilation with CO2 sensors and monitoring of air tightness and indoor air quality are strongly recommended techniques.

(20) In order to take technological progress and the development of markets affected by this Regulation into account, and to ensure compliance with international agreements, the power to adopt acts in accordance with Article 290 of the Treaty on the Functioning of the European Union should be delegated to the Commission with regard to the following: specifying requirements for standard leakage checks; extending the list of equipment subject to mandatory recovery of fluorinated greenhouse gases; specifying minimum requirements and the conditions for the mutual recognition of training programmes for persons who install, maintain, repair or decommission the ...[+++] equipment and who check leaks and recover fluorinated greenhouse gases, and for the certification of those persons and of companies that perform such tasks; amending labelling requirements; prohibiting the placing on the market of more products and equipment that contain or rely on fluorinated greenhouse gases; amending the maximum quantities of hydrofluorocarbons that may be placed on the market and exempting the supply of hydrofluorocarbons for specific critical uses from the quota requirement for health and safety reasons; determining the rules for recalculating reference values for the placing on the market of hydrofluorocarbons by individual undertakings and amending or supplementing the mechanism for the allocation of quotas; revising the thresholds for reporting requirements; establishing requirements for the reporting systems on emissions of fluorinated greenhouse gases and the use of the data on emissions collected by the Member States; including other substances with a significant global warming potential in the lists of substances covered by this Regulation and updating the lists on the basis of new scientific findings, in particular the global warming potential of the substances listed in the annexes to the Regulation.

4. The Commission shall be empowered to adopt delegated acts in accordance with Article 20 specifying requirements for the leakage checks to be carried out in accordance with paragraph 1 of this Article for each type of equipment referred to in that paragraph, identifying those parts of the equipment most likely to leak, and amending the list of equipment in paragraph 1 of this Article to include other types of equipment in the light of market trends and technological progress.

3. In laying down the measures referred to in paragraphs 1 and 2 of this Article, Member States shall, as far as is economically and technically feasible, ensure that inspections are carried out in accordance with the inspection of heating systems and other technical systems referred to in Article 14 of this Directive and the inspection of leakages referred to in Regulation (EC) No 842/2006 of the European Parliament and of the Council of 17 May 2006 on certain fluorinated greenhouse gases
