This document discusses the Dutch "de Stroomversnelling" program for renovating row housing to net zero energy buildings (nZEB). It was developed to accelerate deep retrofitting of housing associations and private homes. The program aims to convert 11,000 homes within 10 years through an integrated approach and new business models like an energy performance fee. It represents a shift from one-off pilot projects to implementing renovations at scale across entire regions. Further deals are now being developed in other Dutch provinces to continue driving the transition to energy neutral neighborhoods.
