Greenhouse gas emissions from the operation of existing buildings are significantly higher than those generated by new construction—that is, from materials and their use during construction, which account for 25%, while building operations represent 75% of emissions. And this is without accounting for the vast number of buildings falling under the concept of energy poverty.
Against this backdrop, the 'Proyectar a Conciencia' (PAC) competition continues to advance the debate surrounding "building better versus improving what is already built" in its fifth edition. As always, the competition invited students and architects to present a vision of a better society through the energy retrofitting and partial physical transformation of institutional, private, or public infrastructure.
