This paper presents methodology of study of the synergetic energy/environment’s constrains relevant to the residential buildings settlement’s sustainability. Presented are results of the design of a sustainable Net Zero Energy Buildings Settlement. Implementing integrated building design building’s dynamic behavior and energy efficiency have been optimized by the BPS resulting in crucial reduction of loads of the initial designs. Further multidisciplinary engineering optimization lead to the settlement of NZEB status (HVAC system’s heat pumps using sea water, and other building’s technical systems powered exclusively by RES (solar thermal, PV, wind and biomass), and water recycling bio-aquatic water treatment are closing the village eco-sustainability.
