The European Union has set specific targets for reducing energy consumption, shifting the main focus of European energy policytowards a firm commitment to enhancing energy efficiency. In light of the limited progress reported in Greece's energy efficiency action plan, the objective of this paper is to help redesign the near-term national policy framework. In this respect, a risk-oriented optimisation model is developed to support the optimal budget allocation to energy efficiency measures, with a view to achieving the 2020 national targets. The transdisciplinary methodological framework initially builds on the Energy Efficiency Action Plans for Greece and involves stakeholder engagement, multiple-criteria decision making and portfolio analysis. The evaluation of the policy instruments is based on two criteria, namely energy savings and implementation risk, under a set of technical and financial constraints. Finally, the robustness of both the optimal policy portfolios and the individual policies composing these portfolios is assessed. The results indicate that, given the financial and technical constraints, the 2020 target cannot be achieved. By stochastically analysing the impact of external uncertainty, three policies emerge as the most robust, while portfolios achieving savings of more than 1000 kTOE until 2020 are found highly vulnerable to underlying uncertainties.

The INTENSSS PA project, funded by Horizon 2020, the Framework Programme for Research and Innovation of the European Union, aims to support the local authorities involved and their stakeholders to develop an innovative integrated sustainable energy planning concept through a participatory, interdisciplinary and multilevel process. By building individual and institutional capacity of the actors involved, using the Regional Living Lab approach, the concept will be applied in order to develop seven sustainable integrated energy plans. In this first article the project activities and the results achieved so far are preliminary described, anticipating a more extensive and detailed publication on the project planned for the December edition of UPLand – Journal of Urban Planning Landscape & Environmental Design.

A number of microeconomic choice models are currently applied to demonstrate systematic biases in energy consumer behavior. The models highlight the hidden potential of energy savings from policies that target the so-called behavioral anomalies. Nevertheless, whether these patterns are repeatable or not is not clear, because the efforts to determine the transferability or generalizability of these models are practically nonexistent. This paper uses a unique collection of empirical data from five EU countries collected within the CONSEED project to refine and develop further the standard consumer decision model, validate it for policy purposes, and elaborate on its transferability between countries. The pooled samples allow for a more reliable investigation of the relative importance of the factors influencing consumers' attitudes and beliefs towards energy investment decisions. Based on the statistical tests conducted to evaluate the "transferability" of the pooled models (i.e., the possibility of creating a "universal" model of EE from the pooled model), it can be argued that the models are transferable in specific cases since attitudinal factors and demographic characteristics play a significant role. Although the pooled models are validated, any extrapolation of the above-mentioned findings to specific populations in terms of "space" (i.e., country) and "target" (e.g., sectors and technologies) should be approached with caution from a policy perspective. ; publishedVersion
