Nationale und internationale Umweltdebatten fokussieren oft auf das Ziel, eine Senkung der Treibhausgasemissionen zur Schonung des Klimas zu erreichen. Entsprechend stehen die Themen "Erneuerbare Energien" und "Energieeffizienz" vermehrt im Vordergrund. Die Ökodesign-Richtlinie 2009/32/EG war ein Beispiel für diese Vorgehensweise. Obwohl die Richtlinie prinzipiell alle Umwelteffekte im Lebenszyklus eines Produktes in den Blick nimmt, lag der Fokus der bislang beschlossenen Durchführungsmaßnahmen auf der Steigerung der Energieeffizienz.
Im Rahmen der Richtlinie wurde bereits bedeutsam in die Gestaltung von energiebetriebenen Produkten wie z. B. Kühlschränken und Lampen eingegriffen und durch die erlassenen Mindesteffizienzanforderungen ein entscheidender Beitrag geleistet, die CO2-Emissionen zu reduzieren.
Mit der geänderten Ökodesign-Richtlinie 2009/125/EG wurde der Geltungsbereich auf energieverbrauchsrelevante Produkte erweitert, so dass sich die Frage stellt, ob im Zuge dieser Erweiterung andere Umweltziele stärker in den Mittelpunkt rücken. Zwar spielt die Wirkung auf den Energieverbrauch auch bei zahlreichen nichtenergiebetriebenen bzw. energieverbrauchsrelevanten Produkten eine entscheidende Rolle, doch gerade die Frage, welche weiteren Ressourcen bei den einzelnen Produktgruppen klimapolitisch bedeutsam sind, muss produktspezifisch neu beantwortet werden.
Vor diesem Hintergrund wird dieser Artikel aufzeigen, welche Fragen bei der Untersuchung neuer Produktgruppen wie z. B. Dämmstoffe und Fenstern aufkommen werden und es wird eine erste Einschätzung gegeben, wie eine neue Ressourcenbetrachtung innerhalb der Ökodesign-Richtlinie aussehen kann.
Strategic policy packages to deliver energy efficiency in buildings : their international evidence
(2013)
The project "bigEE - Bridging the Information Gap on Energy Efficiency in Buildings" presents comprehensive information for energy efficiency in buildings and the related policy on the international internet-based knowledge platform bigee.net.
To develop the evidence-based information required for bigee.net, we addressed in a different and more systematic way than usual the question of how policy can support improved building energy efficiency most effectively: We combined (1) a theoretical, actor-centred analysis of market-inherent barriers and incentives for all actors in the supply and use chain of (energy-efficient) buildings to derive a recommended package combining the types of policies and measures the actors need to overcome all these barriers, with (2) empirical evidence on model examples of good practice policy packages to check if advanced countries have indeed used the combination of policies we derived from the actor-centred analysis.
In this way, we found that the recommendable policy package for new buildings is similar to the well-known one for appliances, but with the objective to mainstream nearly zero energy buildings. By contrast, the task for existing buildings is two-dimensional - increasing the depth of renovation first, to savings of 50 to 80%, and then the rate of energy-efficient renovation to 2% or more p.a. - and so the policy package needs more emphasis on individual advice, incentives, and financing. The paper presents the recommended packages as well as a comparison of existing national policy packages from California (USA), China, Denmark, Germany, and Tunisia and what we learned from it for effective packages and implementation.
Refrigerators and freezers (subsumed under the term "cold appliances") are among the most widely used electrical appliances in the residential sector all around the world. Currently, about 1.4 billion domestic cold appliances worldwide use about 650 TWh electricity, which is 1.2 times Germany’s total electricity consumption, and cause CO2 emissions of 450 million tons of CO2eq.
Although the specific electricity consumption per volume of cold appliances has decreased during recent years due to technical progress and policy instruments like labelling and eco-design requirements, total worldwide energy consumption of these appliances is on the increase. Scenario calculations were carried out for 10 world regions by the Wuppertal Institute. Results show that about half of the energy consumption could be saved with the most energy-efficient appliances available today, and even higher savings will be possible with next generation technologies by 2030. According to the analysis, these savings are usually very cost-effective.
All these aspects are part of the new website "bigEE.net - Your guide to energy efficiency in buildings" which aims to provide information about technical options but also about policies to support the development of energy-efficient appliances.
To initiate and foster market transformation of energy-efficient appliances it is highly advisable for policymakers to generate appliances-specific policy packages. Since each regional market has its specificity (e.g. energy prices, typical appliance affecting the cost effectiveness of efficient appliances), the barriers for the market transformation of single product groups are also specific and need to be addressed by appropriate policies and measures. Elements of measures to build appropriate specific policy packages for refrigerators will be presented in the paper, and the refrigerator package from California (USA) demonstrates the successful implementation of a sector-specific package.
What makes a good policy? : Guidance for assessing and implementing energy efficiency policies
(2013)
Which factors are crucial to successfully design and implement a "good practice" policy to increase the energy efficiency of buildings and appliances? This is one of the main challenges for the new web platform bigee.net that provides guidance on good practice policies.
In this paper we examine the question what "good practice" is by presenting a multi-criteria assessment scheme to analyse different policies worldwide.
The assessment scheme contains a set of criteria addressing key factors leading to the success of a policy as well as its outcomes: a good policy addresses all market players and barriers, avoids lost opportunities and lock-in effects, has ambitious and regularly updated energy efficiency levels, and spill-over effects. Other criteria are high energy savings and the calculated cost-effectiveness.
The assessment scheme provides a standardised data collection approach, which paves the way for both qualitative and quantitative evaluation. Furthermore, it can help policy-makers to transfer a successful policy.
The development of the scheme is based on a literature review of worldwide implemented policies and measures that promote energy-efficiency of buildings and appliances. Criteria were operationalized, including a ranking between 0 and 10. The ranking is a decisive factor whether the policy qualifies as good practice. To demonstrate the practicability of this scheme, the paper analyses a good practice example according to the assessment scheme: Energy-Efficient Refurbishment and Energy Efficient Construction programmes of the German public bank KfW.
