World first

the foundation for new world climate society

We set the idea & prototype of post COVID -19 living


The overarching philosophy of PBUs is that the behaviour and lifestyle

of people living in PBUs, whatever the architecture or design of the building,

should be such that fauna and flora can thrive.

PBU 2015 - 2020 is special as precedent | invention | prototype.

Founded by Prof Dominika Batista PhD, MSc & Damijan Jermancic, MDes who were inspired & influenced by local people
Eco-friendly redesigned partially because of unclear ownership. It was created to support original ides of new world order society Balanced Coexistism - BC.
World first PBU is the invention and it lasted like a real life experiment for 5 years till war.

Experiment is successful and as such, it calls for a massive expansion of the idea.


Continent original - CO

Special mix of languages, peaceful coexistence of multiple religions,

inventive cuisine mostly with local produced food, plant based diet with meat/fish

perhaps only once or twice per week, 
talking with fauna and flora subtropics species, inviting friends on outdoor ceremony lunches,

dinners and tea parties, buna ceremonies, interaction with wildlife, 
original music making & listening, avant-garde art and innovative design making. 

Speeding awareness & education on the exceptional importance of nature.

Climate Specific - CS

Sub Saharan country with hot semi-arid climate, '13' months of sun,
temperatures from 3 to 35 degrees Celsius, low humidity 10 months (dry season), 
high humidity 2 months (rainy season), precipitation/annual rainfall 60 mm sunshine 13 months per year, 
cloudiness low, winds sometimes stronger

Plumbing, electrical & heating support of indoor spaces
PBU gets water from municipality once a week or once in 14 days.

Water scarcity is huge.
PBU has its water storage tanks 3800 m3.
Electricity is available 80% of time. Internet is available 50% of time.
Cooking is possible on electricity stove and gas cylinder.
Hot water is provided from two boilers, one in kitchen and one in bathroom.
Natural climate conditions requires heating 30% of time.
This is temporary solved with electric heathers.


It has septic tank/semi phyto-purification, rainwater from the roof is led to the garden. 
PBU residents eat mainly vegetable, fruits, cereals and legumes and

recycle all organic waste into compost (soil conditioner).
90% of local food offer is unpacked therefore artificial waste is minimized.
There is also no food waste.

What we buy, prepare or cook is 100% eaten.


Foot print
It is far from ideal.

All electricity and heating sourcing needs to be changed to solar and passive solar.
Roof water harvesting (rainy season) need to be constructed as support system.


Time usage - day /night
Till now, the time usage of space as important spatial factor, was worldwide neglected.
It shows our general spatial economy and relevance of built spaces on planet Earth,
the justification that artificial space can even exist.
Indoor spaces
Daytime 50% of time (except holidays - EH). Night time 94 % of time (EH).
In-between spaces
Daytime 15% of time (EH). Night time 2 % of time (EH).
Outdoor spaces
Daytime 15% of time (EH). Night time 2 % of time (EH).
Absence daytime 20%, night time 2% (EH).
*residents would spent even more time in the PBU outdoor spaces,

if there would not be so much dust in the air, 
because generally all city is under construction.

Future Timeline for Balanced Coexistism & Personal Biodiversity Unit


We do not think that, in the historical time frame new world order Balanced Coexistism

with Personal Biodiversity Unit - PBU
is the final and eternal lasting system.
But we are convinced that in the coming decades is the only possible quality solution 
for the climate crisis, the planet and the Earth's overpopulation of 8 (2022) billion people. 
When the planet is balanced in the future,
the new world order will be welcome.


comming soon!
