Who needs to do what?
Making net zero energy refurbishments happen is about changing the whole game for the building and housing sectors. And to achieve this move, everybody needs to play.
They own the houses and thus need to have an active role in the net energy refurbishments. Housing providers have to change their usual way to run tenders, setting very ambitious specifications and running open tenders to allow solution providers to innovate. Accompanying tenants and helping them run their new houses in an efficient way will also contribute to the net zero energy performance
Innovation is at the heart of what the construction companies need to achieve. They will lead consortiums bringing together different skills of the building sector (maintenance, monitoring, energy production, technology supply, etc.). They will invent new prefabricated parts allowing high quality and very fast assembly. Innovation regarding their business model is also needed since they will have to sell works (refurbishment) along with services (maintenance) with a 30-year (or more) guaranteed performance.
Moving to a business model based on the total cost of ownership (TCO) over 30 years or more, construction companies demand will also move to products and technology optimizing this TCO instead of the investment cost only. Suppliers will have to procure efficient and reliable products designed to optimize their maintenance.
A 30 years guarantee means new financial opportunities with low risk on a very long-term. A monthly amount of money equivalent to the previous energy bill (called “energy fee”) could payback the refurbishment price on such an important period.
New products and services on the market will probably need new rules to make them feasible in a controlled context. Policy makers will have to drive this change if they want to achieve national ambitious energy efficiency goals.
