GEMINI next Generation house type 60 and 70

The number in the house type represents the number of 1,134 mm × 2,378 mm solar modules. We have designed types 50, 60, 70, 72, 80, and 84. However, we think types 60 and 70 will be the most used types. As we made the photos of the settlement, there had been only what are now types 60 and 80. On the site plan is a mix of types 60 and 70.

Slideable wall/furniture elements for a variable usage as one big living room or a small living room and two additional rooms. We did cost optimization not only at the energy system. Affordability is a key point in every design decision.

Left: drawers instead of basement. Right: air ventilation system with heat and humidity recovery We have shrunk the basement. Drawers that are within the thermal envelope of the house. Perfect conditions for long-term storage. Lots of space; perhaps a homeowner in financial difficulty might even consider renting out some of the drawers as storage space. Biodiversity is only beautiful outside. The ventilation system with heat and humidity recovery not only saves energy but also keeps unwanted intruders away. HEPA filters can also be used.

Abstract
	To meet the necessary cost optimization targets, we cannot hold the energy problem separate from all other problems: another major problem is housing.

Introduction
	Many imaginations about our future had been created in the past with completely different parameters. Unchecked conclusions from the past endanger our future with unbearable costs.

My personal experience with a profitability transition
	Birds can fly without knowing all the terms of aerodynamics. I reacted with my design change to an ongoing “profitability transition” without knowing the term at this time.

Energy transition
	The long way from random electricity from sun and wind towards 24×365 electricity. Overseen profitability transitions have to be considered as major accidents.

The GEMINI principle: double usage of land
	No better solar power plant, no better housing possible on the same ground is the ultimate target of the GEMINI principle.

Off-grid fast charging settlements
	It can start small, somewhere in a village, with a single GEMINI house with a big PV carport and 100 kW DC charging.

Energy-intensive industry
	I once developed a scale for off-grid solar possibilities depending on photovoltaic size. But now is to make a big jump upwards on this scale: running, energy-intensive industry.

Agriculture: How many square meters does a human need for his food?
	Mankind started as hunters and gatherers. 12,000 years ago, 500,000 m² to 2,500,000 m² per human. With the agricultural revolution, the land use was reduced by 2 magnitudes.

Conclusion
	All parameters are in a constant state of change. We have to check all the parameters and predict the development for the predictable future.
