Law 8/2013 on urban rehabilitation, regeneration and renovation
It requires the public administration to prioritise renewable energy over fossil fuels and fight against the energy crisis with measures that promotes efficiency and development.
The law also establishes the basic provisions of a Building Assessment Report (BAR). In addition to assessing the conservation status of the buildings, the BAR provides information about the degree of compliance with current regulations on accessibility, and includes the Certification of Energy Efficiency. The Report is required for residential apartment buildings more than 50 years old that have not already passed a Technical Building Inspection.
