Evaluating the need for economic support policies in promoting greenhouse gas emission reduction measures in the building sector: The case of Greece

During the last decade the CO₂ emissions from the residential and tertiary sectors have been rising continuously. This is cause for concern but also an area to be targeted for emission reduction measures in national action plans. This paper proposes a methodological framework, using the Greek building sector (characterized by an aging building stock constructed mostly in the period before 1980) as a case study for the examination of the economic attractiveness of possible measures, which incorporates crucial parameters such as local climate, use of buildings, age of building stock, etc. that affect the energy conservation potential and consequently the economic performance of available measures. Utilizing this framework, the approach is able to classify measures into three categories, namely ‘win–win’ cases (i.e. where the implementation of emission reduction measures presents a net economic benefit for end-users), measures that require the implementation of appropriate economic support policies in order to make them economically attractive for end-users, and measures that have excessive cost. The results indicate that the emissions reduction potential of ‘win–win’ cases is significant. They also demonstrate how individual measures can provide significant reductions if carefully targeted economic support policies are applied. Finally, sensitivity analyses performed with respect to the discount rate applied indicate that it has a substantial impact on the economic performance of some measures and consequently on the magnitude of the ‘win–win’ potential associated to emissions reduction.     

Actual interaction effects between policy measures for energy efficiency—A qualitative matrix method and quantitative simulation results for households

Starting from the conditions for a successful implementation of saving options, a general framework was developed to investigate possible interaction effects in sets of energy policy measures. Interaction regards the influence of one measure on the energy saving effect of another measure. The method delivers a matrix for all combinations of measures, with each cell containing qualitative information on the strength and type of interaction: overlapping, reinforcing, or independent of each other. Results are presented for the set of policy measures on household energy efficiency in the Netherlands for 1990–2003. The second part regards a quantitative analysis of the interaction effects between three major measures: a regulatory energy tax, investment subsidies and regulation of gas use for space heating. Using a detailed bottom-up model, household energy use in the period 1990–2000 was simulated with and without these measures. The results indicate that combinations of two or three policy measures yield 13–30% less effect than the sum of the effects of the separate measures.
