Energy Performance requirements using the Cost-Optimal methodology – Overview and Outcomes 2012, Concerted Action EPBD

Share this Post:

This report is the result of the work performed in this field under the Concerted Action EPBD in 2011-2012 and summarises the main outcomes of the discussions on cost-optimality, including statistics from national plans.  

 

The Concerted Action EPBD theme “Energy Performance requirements using the Cost-Optimal methodology” focusses on EPBD recast articles 3-8, as well as to Annexes I and III regarding primarily the cost-optimal procedure.

 

The recast EPBD obliges MS to ensure that minimum energy perfromance requirements are set with a view to achieving cost-optimal levels. The cost-optimal level is defined as the energy performance level which leads to the lowest cost during the estimated economic lifecycle. MS must report on the comparison between the minimum energy performance requirements and the calculated cost-optimal levels using the Comparative Methodology Framework (art. 5.2, 5.3, 5.4 and Annex III) provided by the EC (Commission Delegated Regulation No 244/2012 of 16 January 2012 and relevant Guidelines (2012/C 115/01) outlining how to apply the framework for calculating the cost-optimal level).  

 

The report “Energy Performance requirements using the Cost-Optimal methodology– Overview and Outcomes 2012” deals in specific with:

  • cost-optimal procedures including the legal framework, the comparative methodology framework requirements (defining the reference buildings, assessing the final and primary energy needs of the reference buildings with and without energy efficient interventions, and calculating the relevant costs) and early experiences with cost-optimal calculations;
  • compliance checks for energy requirements in new buildings;
  • requirements for existing buildings.
