The Energy Performance of Buildings Directive (EPBD) allows Member States to choose alternative measures in place of regular inspection of heating and air-conditioning systems, and many of them do so. But this option imposes an obligation to report the alternatives and demonstrate they are equally effective in saving energy. How that should be done has been the subject of several Concerted Action EPBD meetings and papers, and a Working Group has proposed a framework for approaching the task. Whatever methodology is used, there are likely to be difficulties with obtaining reliable data and justifying the assumptions needed to construct an energy model.
This report from the Concerted Action EPBD provides an evaluation and comparison of some of the measures proposed as alternatives to inspection in Member States. The full report can be downloaded here.
