True well-being only exists if it is shared. The architecture/building binomial represents one of the most polluting sectors in the world but, at the same time, it is one of the most important levers for improving the quality of life in closed environments, guaranteeing greater comfort: thermal, acoustic, visual, respiratory. We need to learn how to measure: emissions, consumption, building performance; we need to learn to distinguish between green and non-green buildings, a difference which impacts on costs but also on people. "In accordance with the law" is not always synonymous with "done well", which is why it is important to have responsible designers and companies working together to design shared comfort, a central theme which unites the work of ACPV Architects and the Marazzi corporate philosophy.
