electric storage and generating : a. DC or inverter-AC by " artificial photo or vent electric"
   Zero heat ( grid) energy building for less than 100 Euros/ sqm construction costs

In the final 80'/90 the climate sector professionals thought that "solar active house" construction is more expensive than " solar passive house" construction  !

THE BEST SOLUTION : FROM BOTH THE ADVANTAGES

Passive Shell ( cover called " house, home") : Nearly Zero Energy Building Standart
Active Shell/House climatization : Zero Energy Building Standart

Alternatively house prototype construction : cast stone

This are demonstration prototype ideas,

20 sqm + morphing furniture ~ 40 sqm,

F.A.S.org/UN-habitat 32-38 sqm " starter family house" + morphing furniture 40 sqm  ~ 100 sqm,

60,5 sqm ( ICON 3d print ) + morphing furniture ~ 150 sqm,

F.A.S.org/UN- habitat 72-78 sqm + morphing furniture ~ 180-195 sqm "living area"
