With a global construction price index  we get a global credit value index, for finance comparision like
" gold- standart"( before Bretton Woods ) or silver - Thaler( phonetic " Dol(l)ar" ) standart.

                     OECD- Bilanzierungs- und Bewertungsregelwerk

                     Construction Material ( Kg)  need,  orcament/Kostenvoranschlag
    Given a global " passive house price" with 200 €/$ per sqm for new construction :   
    80% Kreditbemessungsgrundlage Neubau : 160 €/$ per sqm value index
              ----------------------------------------------------------------------------------------

   80% sub-prime/ 2.Rang  Kredit-Beleihungswert : 128€/$ per sqm credit max., Risc Tax to pay
   60% prime-rate/1.Rang  Kredit-Beleihungswert : 96€/$ per sqm credit max. , prime tax

    Ground/terrain : zero credit , 100% cash or with other ground/terrain interchange

   Work price : zero credit, 100% cash ( "Muskel-Hypothek" is more worth= D.I.Y. )
Kredit-laws and orders are based by physical experience and cyclical repetition( Schweine-Zyklus):


King-Davenant Law ( Gold/ bushel wheat ratio)and v.Weizsaecker " eternal tax law" ( material value less progressive/linear amortization quotes)
                         AfA=       A( mortization)  f(üer)  A(bnutzung)
A house, built 1999 for 250 Euros/sqm net, has 2019 a progressive book-value about 62,5€/ sqm.( 4 years x7%,6 years x5%,6 years x 2% and last 4 years x1,25% progressive AfA , each investor in Germany worked with this numbers)
                   Market price crash potential related to amortized objects bookvalues : over 90%
                       


Why do you think that after 20 years ( patent validation max.) the same object selling price fells abruptly 70-80% !   Included salaries drop or disemployment or " pre- pension"
King-Davenant law and espacenet : international market Polygraph

An important decision,  not only valid for the construction sector :
https://translate.google.com/translate?hl=de&sl=de&tl=en&u=https%3A%2F%2Fwww.n-tv.de%2Fratgeber%2FEuGH-kippt-deutsche-Honorarordnung-article21126176.html
It means from fixed honorar now " floating= variable" fees/salaries,  each client mandates about the service price  ! No minimum !
The value for Architect  Passiv-Haus-plans : 200 Euros each ~ 1% total construction costs
 Referenz : Isorast Architectur competition in 1996, 40 bought Passiv house plan concepts and sold for 398 DM

Foam block technology is now, 2019, mostly patent-free, so average prices 70% deeper than in the 90',when the costs per sqm construction has been +- in the 500 Euros/sqm range.

Now low cost production and appropriate market price value : 150 Euros/ sqm

Assumption : 30 sqm wall + 20 sqm tect + 7 sqm door/windows the peak room heat becomes :                                             
                                                                      630 Wattp

1. Option : https://www.patentauction.com/patent.php?nb=11044
                             decrease to +-                400 Wattp/300 Wattp


Heating system : a.Infra-red heater                     

                                        b. heat pump

Each one with C.O.P. ( or performance aequivalent)  10
                               electric heat need :          40 Wp/35 Wp


Infra-red optimized "C.O.P. 10" ( heat bulb,  2 seriell bulbs connection, frequency controler)

or seriell connected OSMA Tech heater

Air-to-Air Heat pump with C.O.P 10 :
 conventionell average  C.O.P. 2,5 + improved magnetic motor + improved compressor

                                              40 e-Wp room heating ( or cooling) demand :
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
https://www.jovoto.com/projects/300house/ideas/12501?page=1&scope2=published&scope=prizes

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"

 cash price/ credit " geral lowest market value"- principle " new construction"

ergo :

20000 US$ microhouse  cash price maximum / 

    900 US$ x 0,6 x 0,8 = earth dome prime rate credit maximum 432 US$
