Structural energy conservation in the built environment

Because there is still plenty of scope for major energy savings in the built environment, in 2005 the Dutch Ministry of Economic Affairs investigated the feasibility of a system of so-called White certificates (energy-saving certificates) for application in this sector. Under the system it would be obligatory for energy providers to obtain such a certificate. At the request of EnergieNed, CE has analysed three alternative systems, allowing them to be properly evaluated against the proposed White certificates. The study surveys the most relevant segments and measures and suggests criteria for comparing the various systems. Each of the systems are then put through the calculations and compared as to impact and anticipated support. A workshop with stakeholders was also organised. The study indicates that the additional energy savings of 65 PJ/y envisaged by 2020 constitutes an ambitious target. Even if the conservation measures are dovetailed perfectly with ‘natural’ replacement and renovation schedules and so on, there will still be substantial expenditure involved. There is no one 'ideal' system. Rather, the choice is a political one, between comparatively low-cost systems with fairly major implications in terms of implementation and systems costing far more but easier to implement. CE also proposes several compromises. When it comes to choices and estimates, the report reflects the opinion of CE.
