Only recently have commercial property owners started to recognise that the lower energy and operating costs and better rentals of energy efficiency buildings translate to increased capital value. As different building owners (such as public, private, investors, commercial, and institutional) have diverging interests in energy efficiency, different approaches are required to develop incentives and build awareness. Programmes like Netherland's EnergieSprong that focus on transforming the building value chain as a system, work with all the decision makers in the system. Many building retrofit programmes undervalue the multiple benefits of energy efficiency initiatives. Health benefits in terms of reduced hospital visits, doctor's visits, prescription costs, and reduced sick days, can exceed the energy cost reduction significantly in some cases by 400%.
