The EU project "Collaboration for housing nearly zero energy renovation", abbreviated to COHERENO, mada a valuable contribution to achieving the EU’s energy efficiency and climate protection goals. Nine institutions from five European countries were involved in the project.

By March 2016, they developed proposals and concepts for promising cross-sector and company business models for high efficiency refurbishment of single-family houses to nearly zero-energy housing. The models were to pave the way for refurbishment from a single source. From financing, consulting and planning, right through to implementation – all parties in the construction process are  involved.

A major goal of COHERENO was to improve the quality of the construction measures by providing specific support to all stakeholders, thus increasing customer confidence. With these two key aspects, nearly zero-energy houses can gain credibility and acceptance, and win a higher market share.
