In order to be able to optimise existing processes, technical qualifications, actions to be taken and roles must be known and tasks and functions of the stakeholders assigned. The assessment of the process for nZEBs depends strongly on the perspective. Building owners, investors, tenants, the construction industry, providers of energy efficiency solutions and planners have different interests and are involved in different phases in the life cycle of buildings. There is a general lack of understanding, transparency and uniform methods when it comes to the overall process of nZEBs.  Which costs and time horizons are significant for different actors and to what extent?
