S.L. 623.1 Art. 6Calculation of cost-optimal levels of minimum energy performance requirements. S.L. 545.16.

(1) The Building and Construction Authority shall establish standard cost-optimal levels based on macro-economic scale and micro-economic scale of minimum energy performance requirements using the comparative methodology framework established in accordance with Schedule III and relevant parameters, such as climatic conditions and the practical accessibility of energy infrastructure, and compare the results of such standards with the minimum energy performance requirements set out in the Technical Document F.

(2) The Building and Construction Authority shall report to the Commission, at regular intervals, which shall not be longer than five years, all input data and assumptions used for such standards and the results thereof. The report may be included in the Energy Efficiency Action Plans (EEAP) referred to in regulation 24(2) of the Energy Efficiency and Cogeneration Regulations.

(3) If the result of the comparison performed in accordance with sub-regulation (2) shows that the minimum energy performance requirements in force are significantly less energy efficient than cost-optimal levels of minimum energy performance requirements, the Building and Construction Authority shall justify this difference in writing to the Commission in the report referred to in sub-regulation (2). Such report shall, to the extent that the difference cannot be justified, be accompanied by a plan outlining appropriate steps to significantly reduce the difference by the next review of the energy performance requirements as referred to in regulation 5(1), (2), (3) and (4).
