The decisive difference to all other low energy houses is:

Bio-Solar-Houses need no moisture barriers and no ventilation systems!

A partly glazed weather protected house heats up like a greenhouse with the daylight the well thermally insulated house cladding of the inner timber house from outside. The steam produced inside the house by the occupants diffuses together with the associated smells, without being able to condense the damaging condensate through the diffusion opening inner house cladding into the air space between the inner house and the weather protected house. From there it goes outside naturally under its own steam through the openings.

Nature renders moisture barriers superfluous for protecting the house cladding from condensation damage and possibly unhealthy ventilation systems for dehumidification of the living space.

Because for them no artificially produced atmosphere or dust swirling ventilation systems are necessary, the occupants live in a natural healthy climate with low relative humidity, clean air to breathe and dry walls. Mould growth is physically excluded and there are also no dust mites. Also viruses, bacteria, allergens and other pollutants which the heating and ventilation systems can produce are equally excluded as are disturbing circulation noises.

A wall radiant heater warms the occupants as if by rays of the sun and fosters their health.

Also persons suffering from allergies feel well in this natural climate.

Heating costs are not only energy costs but also the costs for maintenance, repairs and depreciation of the heating equipment. All these together are running costs and they are becoming ever more expensive.

Therefore when comparing houses you not only take into account the building costs, rather much more the running costs.

Building costs are a one off - Ever increasing running costs are a burden for life!
