Overview of Cost Baselines for three Building Levels: Solution sets for the Cost reduction of new Nearly Zero‐Energy Buildings – CoNZEBs

This report documents the work of the CoNZEBs project on setting the cost baselines for different building energy performance levels. It analyses and compares the investment and energy costs in four different countries (Germany, Denmark, Italy and Slovenia) for:
⌂ New multi‐family houses built according to current national minimum energy
performance requirements
⌂ Existing examples of NZEBs (nearly zero‐energy building) multi‐family houses
⌂ Multi‐family houses that go beyond the NZEB‐level
The work is based on literature on building costs, on the knowledge gained by the different research organisations and complemented by the cost experience of the national housing organisation. The work of Concerted Action EPBD on NZEBs is used as well.
The result of these efforts is the starting point (baseline) for evaluating the technical solution sets for nearly zero‐energy buildings that were identified to reduce the additional costs currently required to build a better energy performing multi‐family house than determined by the minimum energy performance level of the national building laws. This exercise will be documented in deliverable D2.2 “Comparison of costs for new multi‐family houses, NZEBs and beyond”.
