Resumen de An approach and a tool for setting sustainable energy retrofitting strategies referring to the 2010 EPBD

C. Charlot Valdieu, P. Outrequin

• The 2010 EPBD asks for an economic and social analysis in order to preserve social equity and to promote innovation and building productivity.

  This is possible with a life cycle energy cost (LCEC) analysis, such as with the SEC (Sustainable Energy Cost) model whose bottom up approach begins with a building typology including inhabitants.

  Then the analysis of some representative buildings includes the identification of a technico-economical optimum and energy retrofitting scenarios for each retrofitting programme and the extrapolation for the whole building stock. An extrapolation for the whole building stock allows to set up the strategy and to identify the needed means for reaching the objectives.

  SEC is a decision aid tool for optimising sustainable energy retrofitting strategies for buildings at territorial and patrimonial scales inside a sustainable development approach towards the factor 4. Various versions of the SEC model are now available for housing and for tertiary buildings.
