Abstract
The article presents chosen technological solutions that affect the energy efficiency of multi-family zero-energy buildings – MFZEB. Based on detailed analyzes of 15 buildings built in a climate zone similar to Polish zone, strategies that have direct application in the integrated design process were selected. Both elements and features that can be considered as trends as well as specific cases of MFZEB were indicated. Authors hope that the described problems will contribute to changes in the design of multi-family housing for the 21st century in Poland.
