Figure 4 The graphic presents possible ways of designing housing environments under and on water: I — habitat under water with the ability to float to the surface on sunny days, II — habitat floating on the water surface (graphics by the author) Designed to provide shelter for future refugees due to global warming. According to scientists, the level of the ocean is gradually increasing, absorbing large areas of land. The Maldives, where by 2070 seventy percent of the country’s area will be under water, can serve as an example [13, p. 239]. The project operates as an amphibious half-aquatic and half terrestrial city, and is anticipated to being able to accommodate 50 000 inhabitants. The floating Ecopolis will also be in a positive energy balance with zero carbon emission through the integration of all renewable energies (solar, thermal and photovoltaic energies, wind energy, hydraulic, tidal power station, osmotic energies, phyto-purification, biomass) allowing the production of more energy than it consumes [6, p. 304-305].
