Steps Towards the Integration of Regeneration Processes Obsolete Buildings Envelope Spanish in the Paradigm of Sustainable Development

The aim of the following communication is to carry out a short review of those regulatory and legislative aspects that limit the intervention on the envelope of our buildings on energy rehabilitation through improvements on the envelope of buildings; determine the international scene regarding the evaluation of sustainability in rehabilitation and establish a set of conclusions. Thus this article will be divided into three thematic sections: (1) “Climate change, greenhouse gases and sustainable development”, where the connection of political and institutional interest in reducing GHG emissions with measures established European and Spanish level, with particular emphasis on mechanisms and tools for determining energy efficiency; (2) “The sustainability assessment of buildings”, carried out a review of these assessment tools and/or certification of sustainability, as well as those based on an environmental study, and sometimes economic, policy through LCA and adaptations of this methodology to the complex reality of the buildings; and (3) “Energy efficiency and sustainable construction in the rehabilitation of buildings” section in which conclusions are drawn about the integration of energy rehabilitation processes within the paradigm of sustainable development and its potential implementation in BIM tools.
