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.
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.
Dieses Inputpapier soll für japanische Entscheidungsträgerinnen und -träger aufzeigen, was die Hintergründe der in Deutschland zu beobachtenden Welle an Stadtwerke-Neugründungen und Rekommunalisierungen sind. Dabei wird auf aktuelle energiewirtschaftliche Entwicklungen und Rahmenbedingungen in Deutschland eingegangen, die ein besseres Verständnis vermitteln werden. Das Inputpapier soll vor allem japanische Kommunalpolitikerinnen und -politiker in die Lage versetzen, in ihren eigenen Gemeinden fundierte Diskussionen über eine mögliche Stadtwerkegründung zu führen und Entscheidungen vorzubereiten. Dies können sie auf Basis wichtiger Grundkenntnisse und Erfahrungen deutscher Städte und Gemeinden initiieren. Im Laufe des Gesamtprojektes wird im Herbst 2018 ein Werkzeugkasten entwickelt, der zur Unternehmens-Neugründung in Japan wichtige Hilfestellungen wird leisten können. Ergänzend dazu bleiben juristische und energiewirtschaftliche Fachberatungen unerlässlich, um einen erfolgreichen Start der neuen kommunalwirtschaftlichen Unternehmen zu gewährleisten. Dieses Inputpapier versteht sich daher als erste Handreichung und Hilfestellung für kommunale Entscheidungsträgerinnen und -träger in Japan, damit dort ein Grundverständnis des "Stadtwerkeprinzips" entstehen kann.
Reliably reducing the emissions in the building sector plays a crucial role if the 1.5°C climate target from the Paris Agreement is to be met. The observed trends show a significant increase in building energy use, especially in emerging economies. Counteracting these trends is absolutely essential, especially in the light of urbanisation, population growth and changing lifestyles. In terms of mitigating the climate impact of buildings, ensuring high levels of efficiency (i.e. very low energy needs, especially for heating and cooling) has the greatest potential for saving energy and emissions, and is at the same time the prerequisite for effective use of energy from renewable sources. Clearly defined targets and suitable metrics are essential to enable appropriate design decisions. Implemented projects clearly indicate that quality assured design and construction lead to reliable in-use energy performance. Effective policy packages to address opportunities and challenges are important drivers to support the uptake of state-of-the-art efficiency measures in the urban building sector.
