Summary/Abstract

There are several technoeconomic modeling approaches that provide quantitative results such as costs and the level of achievement of certain renewable energy (RE) policy targets. These approaches often do not consider other important factors for policy implementation (such as socio-political aspects and stakeholders' preferences). Recent multicriteria analysis (MCA) approaches attempt to integrate these multiple aspects in decision making process. In this respect, aim of this paper is to combine technoeconomic modeling and MCA approaches in a general analytical framework incorporating multiple aspects. Each method in an RE policy interaction problem can feed in the necessary policy information for the subsequent steps of an ex-ante and an ex-post assessment in a decision tree, starting from recognizing the need for implementing a new policy in parallel to the incumbent ones, assessing the actual policy costs and finally identifying the social acceptability of these RE policies.

Summary/Abstract

The building sector in Greece presents a huge energy saving potential, the largest part of which is remaining unexploited. The recently enacted legislation for the energy performance of buildings, in combination with the financial support provided by funding programmes to low income families is expected to significantly boost the deployment of energy efficient technologies in the Greek domestic sector. The exploitation of these legal and financial instruments follows a formalised process of energy audits, resulting in buildings classification and in the submission of Energy Performance Certificates (EPCs) including suggestions to improve the dwellings' energy performance. The paper aims at an ex-ante evaluation of the market trends revealed by EPCs in Greece, in order to identify the perspectives of individual technologies and to assess the degree to which the certification procedure helps in improving the energy performance of buildings. The results indicate a strong trend towards less cost-effective technologies, revealing a sub-optimal allocation of financial resources and putting into risk the path towards the achievement of EU targets for 2020.
