Policies for Smart and Sustainable Renovation of Urban Blocks

The objective of this chapter is to recognize the fundamental issues for the low levels of efficiency of the strategies for the energy renovation of the building stock in Greece. The regulatory framework for the energy efficiency and energy renovation is analysed, and the main policies that have been adopted for upgrading the building stock are summarized. Strategies for the energy renovation of buildings have often led to the further deterioration of the built environment as the Greek city is still characterized by the low quality of life and the low energy efficiency of buildings. A tool for assessing the overall benefits of renovation strategies at the urban block scale is presented as a means for the optimization of the efforts and profits. A smart strategy of renovation including thermal insulation, passive design, and green roofs should be context based considering urban form, urban geometry, and climate.
