Pass­ive Houses in 50 sol­ar- and 100 cli­mate pro­tec­tion es­tates in the former coal- and steel-re­gion North Rhine-West­phalia, Ger­many

Since the 1990s, NRW has been pro­mot­ing Pass­ive Houses: 6000 res­id­en­tial units, sev­er­al oth­er build­ing types, and 150 sol­ar/cli­mate pro­tec­tion hous­ing es­tates. Con­tinu­ous gov­ern­ment­al sup­port for Pass­ive Houses, with re­new­ables in the con­text of urb­an de­vel­op­ment, is the most suc­cess­ful strategy.

Only num­bers count - life cycle costs in so­cial hous­ing

Aus­tri­an re­search pro­ject, KliNa­Wo, de­mon­strates that so­cial hous­ing pro­jects with high en­er­get­ic qual­it­ies can be real­ised with very little ad­di­tion­al cost, of ap­prox­im­ately only 3%. The meas­ured en­ergy con­sump­tion of 14 kWh/m² net dwell­ing area cor­res­ponds very well to the de­mand cal­cu­lated us­ing the PHPP.

New fin­ance mod­el for apart­ments to ap­proaches neut­ral liv­ing ex­penses be­fore and after En­erPHit ren­ov­a­tion

Fin­an­cing is cru­cial to un­lock the enorm­ous po­ten­tial of en­ergy ef­fi­ciency. With the sav­ings on en­ergy and the sav­ings of 30 years main­ten­ance the loan plus in­terest can be paid back eas­ily

­Long-term mon­it­or­ing of the suc­cess­ful en­ergy ef­fi­cient Brun­ck-Quarter mod­ern­iz­a­tion

In 2001 BASF re­vi­tal­ized a res­id­en­tial dis­trict, the first time use of Pass­ive House com­pon­ents in a dis­trict re­fur­bish­ment. Ten years later a mon­it­or­ing pro­gram con­firmed that all build­ings still per­form as ex­pec­ted. Achiev­ing nearly the Pass­ive House stand­ard in a mod­ern­iz­a­tion is cur­rently pos­sible with a pay­back of 20 years (2018).

Sim­il­ar­it­ies of the Pass­ive House and the DGNB-sus­tain­bil­ity cer­ti­fic­a­tion con­cepts

The Pass­ive House Stand­ard stands for healthy, com­fort­able liv­ing and highest en­ergy ef­fi­ciency. There are par­al­lels to the goals of green build­ing rat­ing schemes like the DGNB, but com­par­ing the out­put of the cer­ti­fic­a­tion sys­tems is dif­fi­cult. There­fore, an ana­lys­is to in­vest­ig­ate syn­er­gies between the cer­ti­fic­a­tion sys­tems has been car­ried out.
