Solution sets and technologies for NZEBs: Solution sets for the Cost reduction of new Nearly Zero‐Energy Buildings – CoNZEBs

Solution sets are collections of energy efficient technologies used in nearly zero‐energy buildings (NZEB) that in the specific case constitutes a building that meets the national NZEB requirements or beyond. A solution set may vary from one context or location to another and may include any number of technologies. Solution sets have the potential of reducing the cost of currently realised NZEB projects, i.e. a combination of technologies that support/supplement each other in striving towards NZEB at less investment cost. A solution set reduces the overall investment cost for a NZEB. This is achieved either by introduction of less costly solutions in general or by implementing combinations of cost and performance reductions in combination with other cost and performance improvements.
