The GAIA  house with Insulation coating decrease in delta-phi 20°K  climate area the heat demand to 550 Wp/20 sqm,which by improved C.O.P. 10 heat pumps means 55 Wp electric  room air conditioning.

Using steel frame, and HDPS from companies like GeoFoam
A dwelling or commercial space can be constructed for 10%
of the cost of a modern structure.
And more than twice as durable.

Yes and we have also steel-foam and alufoam construction panels houses offer in this" compared 1/10 "
price level.

Next now the "Nearly Zero (Energy Building) " heating and cooling system :

Natural ( from conventional human view "extreme") NEGATIVE/SUB-ZERO 10° CELSIUS climate condition :and in this climate condition the humans their re-/action for well-being/health safety
https://translate.google.com/translate?hl=de&sl=de&tl=en&u=https%3A%2F%2Fm.spiegel.de%2Fwissenschaft%2Fnatur%2Fmount-everest-wetterstationen-messen-verblueffende-uv-werte-a-1301499.html

Ten degrees Celsius negative and walking in T-shirts ( if not...). ?!
(hot or cold ? Ultra-violett radiation warming effect( Solarium)  compared to ( hot or cold ? )infra-red radiation warming effect. ? Black/White light Boltzmann spectrum

 Civil Court In/Sane well-being " Minimum-Temperature" for " inhouse living " decision. :
https://translate.google.com/translate?hl=de&sl=de&tl=en&u=https%3A%2F%2Fportal.uniplaces.com%2Fde%2Fwohnungstemperatur-gerichtsurteil-in-der-nacht-muessen-es-mindestens-18-grad-sein%2F
If the outer temperature is in the 0°Celsius state to heat up to 15°Celsius inside  or up to 20°Celsius is an 100% more energetic consume decision. !

5 thermic.degrees more are not calculatoric 25% : 0 to 15 compared 0 to 20 more
                                    but caloric 100% BTU more !
And 100% more energetic costs and the global climate temperature increasing action. !

So the new construction codes normations  and civil courts decisions demands :
             
                          SURPLUS ENERGY CONSUME, BY LAW !
                        WITHOUT SCIENTIFICAL FUNDAMENT  !

The use from such inventions and intentions
https://spectrum.ieee.org/energywise/energy/environment/wristify-thermoelectric-bracelet-would-reduce-energy-consumption

decreasing the room temperature( from average 20°C to 18°C or 16°C   and hold /increase body temperature

                   -by Court decision - illegal  : the room temperature decrease- inside house !
Or : http://www.rexresearch.com/cuinanoagwire/cuinanoag.html
      ...... ELEMINATE NEED OF INDOOR HEATING ( if allowed by CIVIL COURT DECISION)


IR-heater with direct far/near waves body and objects warming and room by well warm  18°Celsius POSITIVE heating :

           not sufficient inside house by " intelligent"  climate NEGATIVE changing "Court decision".

Who gives these judges scientifical consultance. ? Are they up to date.  ?

                Anti-Kyoto-Contract and Anti-Paris Contract decision

We should recycle “global warming” to heat our homes.


If one problem is heating up our planet
Another is needing to heat our homes


Sound like a single solution could resolve both issues.
Instead of burning fuels for heat,
Just use heat pump for global cooling

A heat pump moves by mechanical work from. place A to place B an heat volume, termed f.e. in BTU

We have to spent 1 unit energy to move in average 2,5 units energy.( by conventional air-air heat pumps)
But because this 1 work unit is often electric we have to spend 1,8- 3 units( sources-mix- dependent)   primary energy to move  in average 2,5 units
Take two boxes : one side cold and one side warm. : middle temperature  ? total kcal value. ?

Take two boxes: one -/one +  and connect them with passive heat-exchanger : middle temperature ? total kcal value ?

Take two boxes : one-/one + and connect them with a thermodynamic Carnot cycle equipment:       

           you have to invest work energy units for this now active/forced process
YOU change the two boxes  ,now system,middle temperature energetic

And by the above calcuation : 2,5 units + 1,8-3 units= 4,3-5,5  units are the energetic invest for 2,5 units movement
https://de.m.wikipedia.org/wiki/W%C3%A4rmepumpe
              2,5/4,3 and 2,5/5,5 : the result is called  mathematical Quotient in german thermo-physics
                         
                              GUETEZIFFER, shortly "ETA" and defines the " Carnot-factor"


             The emitted heat (kcal,BTU,KJ) is not and nevermore technical restoreable( thermical Pandora box)

                by actual conventional physics and her( female) CONSTITUTION

                https://en.m.wikipedia.org/wiki/Thermodynamics

                 
              But process deceleration is possible :  but Carnot-factor ever maximal < 1 ~ 0,9999999......... PERIODE

If we use an air condition style compressed gas system


There are other ways.
Solar radiation can operate fluid-based heat pumps
There are also peltier/seebeck thermoelectric generators
which act as a heat pump between two places
and generate energy while doing it.


not that I’m saying it would be an efficient use of a TEG
But that such things are possible, to utilize the excess heat
of ambient sources to heat our homes.
And by the same utility, our hot homes can be cooled by less hot
ambient sources.
