Comparison of the calculated cost-optimal levels with current minimum energy performance requirements
Article 4
1. Member States shall decide, after calculating the cost-optimal requirement levels from both a macroeconomic and financial perspective, which of the two is to be the national benchmark, and shall report their decision to the Commission as part of their reporting obligations in accordance with Article 6. 2. Member States shall compare the outcome of the calculation chosen in accordance with paragraph 1, with the current energy performance requirements for the relevant building category. 3. Member States shall use the result of the comparison referred to in paragraph 2 of this Article to ensure that minimum energy performance requirements are set with a view to achieving cost-optimal levels, in accordance with Article 5(1) of Directive (EU) 2024/1275. 4. Where a Member State has defined reference buildings in such a way that the result of the cost-optimal calculation is applicable to several building categories, it may use that result to ensure that minimum energy performance requirements are set with a view to achieving cost-optimal levels for all relevant building categories.
