Offsite construction offers an effective and rapid answer to the need to provide environmentally and socially sustainable housing to those who need it. The good news is that a community of companies, designers, developers, administrations and researchers ready to take up the challenge already exists. Over 90 innovative players have gathered around Offsite Hub Italia to develop an Italian market for industrialized renovation and new construction able to reduce the time and costs of interventions. And results are not lacking: with offsite it is possible to renovate entire apartment blocks with time reductions ranging from 40% to 60%, intervention costs already comparable to traditional methods, and prospects of savings of up to 15% by aggregating small, homogeneous volumes. By then combining a seismic retrofit with an energy efficiency intervention, offsite can produce savings of up to 30%.
