Lead­ing edge in re­search and prac­tice

As a lead­ing in­ter­na­tion­al and, above all, prac­tice-ori­ented re­search centre, the Pass­ive House In­sti­tute has been in­volved in many highly en­ergy-ef­fi­cient pi­lot pro­jects for dec­ades. Among oth­er things, it provided build­ing phys­ics con­sult­ing and sci­entif­ic sup­port for the first Pass­ive House of­fice build­ing (Cölbe), the first Pass­ive House fact­ory (Ben­sheim), the first Pass­ive House school (Frank­furt am Main), the first Pass­ive House swim­ming pools (Bam­berg and Lün­en) and the first Pass­ive House re­fur­bish­ments (Nurem­berg, Frank­furt am Main, Lud­wig­shafen).

With­in the frame­work of nu­mer­ous re­search pro­jects at re­gion­al, na­tion­al and European levels, the in­sti­tute is con­tinu­ously ex­pand­ing its know­ledge and ex­pert­ise in the field of en­ergy-ef­fi­cient con­struc­tion. 

Re­search pro­jects (ex­amples)

In the AchieveVE-ZEB pro­ject fun­ded by the European Uni­on, teach­ing ma­ter­i­als from es­tab­lished train­ing and fur­ther edu­ca­tion in­sti­tu­tions are re­viewed by ex­perts and ex­pan­ded to in­clude the latest re­search find­ings and cur­rent best prac­tice ex­amples. The ex­pert­ise avail­able with­in the con­sor­ti­um on core top­ics such as step-by-step renov­a­tion, ef­fi­cient build­ing tech­no­logy (e.g. heat­ing re­place­ment or vent­il­a­tion), renov­a­tion with mod­u­lar pre­fab­ric­ated ele­ments, sum­mer com­fort and re­si­li­ence to cli­mate change, as well as re­cyc­lab­il­ity and life cycle as­sess­ment, are taken in­to ac­count in the up­dat­ing, sup­ple­ment­ing and qual­ity as­sur­ance of teach­ing ma­ter­i­als for aca­dem­ics and crafts­men.

The Ger­man Work­ing Group on Cost-Ef­fect­ive Pass­ive Houses was es­tab­lished in 1996 and sees it­self as a link between the­ory and prac­tice. Key is­sues re­lat­ing to en­ergy-ef­fi­cient con­struc­tion have since been de­ve­loped for prac­tic­al ap­plic­a­tion, presen­ted in work­ing group meet­ings and dis­cussed with in­ter­es­ted ex­perts. The res­ults are pub­lished in pro­tocol volumes, some of which are already avail­able free of charge for down­load (in Ger­man).

COM­PLETED | The European Uni­on-fun­ded pro­ject out­PHit bridged the per­form­ance gap between re­search and prac­tice and opened up solu­tions for chal­lenges in ren­ov­a­tion. The out­PHit con­sor­ti­um fo­cused on pro­cess-op­tim­ized re­fur­bish­ment us­ing highly pre­fab­ric­ated com­pon­ents. De­mon­stra­tion ob­jects were ex­amined throughout Europe. The pro­ject part­ners of­fered sup­port and qual­ity as­sur­ance in all sev­en part­ner coun­tries to en­sure that re­fur­bish­ment res­ults com­plied with Pass­ive House prin­ciples. The strict en­ergy re­quire­ments of the En­erPHit stand­ard were the tar­get for the re­fur­bish­ments.

COM­PLETED | The ob­ject­ive of the EU pro­ject Built2Spec was to close the gap between plan­ning and the ac­tu­al ef­fi­ciency of a build­ing. Tab­lets and smart­phones played a cent­ral role in this pro­cess. The Pass­ive House In­sti­tu­te con­trib­uted its ex­pert­ise in highly en­ergy-ef­fi­cient con­struc­tion and qual­ity as­sur­ance to the de­vel­op­ment of the plat­form and worked on the in­ter­faces between the BIM-based plat­form and the plan­ning and design tools PHPP and de­sign­PH. Built2Spec was fun­ded by the EU Frame­work Pro­gram for Re­search and In­nov­a­tion “Ho­ri­zon 2020.”

COM­PLETED | The Pass­ive House In­sti­tu­te par­ti­cip­ated in the EU-fun­ded Sin­fonia pro­ject, provid­ing con­sult­ing and cer­ti­fic­a­tion ser­vices for re­fur­bish­ment pro­jects in the de­mon­stra­tion cit­ies of Inns­bruck, Aus­tria, and Bolzano, Switzer­land. The in­sti­tu­te was also re­spons­ible for de­vel­op­ing and im­ple­ment­ing a meas­ure­ment concept for the de­mon­stra­tion build­ings com­pris­ing 500 units.

In ad­di­tion, the pro­ject ad­dressed the top­ics of elec­tric­al en­ergy ef­fi­ciency and the ev­al­u­ation of en­ergy sav­ing po­ten­tial at the dis­trict level. The res­ults and prac­tic­al im­ple­ment­a­tions de­ve­loped in the pro­ject were shared with the par­ti­cip­at­ing “early ad­op­ter” cit­ies of Pa­phos (Cyprus), La Rochelle (France), Rosen­heim (Ger­many), Seville (Spain), and Borås (Sweden) and trans­lated in­to con­crete, sus­tain­able en­ergy de­vel­op­ment plans that were in­teg­rated in­to the re­spect­ive urb­an re­de­vel­op­ment con­cepts.

COM­PLETED | The ‘Train-to-NZEB’ pro­ject aimed to provide world-class train­ing on en­ergy ef­fi­ciency and re­new­able en­er­gies in build­ings. It was based on newly com­piled cur­ricula which were be­ing im­ple­men­ted in newly cre­ated edu­ca­tion and con­sult­ing centres (Build­ing Know­ledge Hubs) in vari­ous European coun­tries. Busi­ness plans for each train­ing centre and up-to-date train­ing mod­els form the basis for sus­tain­able suc­cess. The aim was to im­prove know­ledge and skills in the con­struc­tion sec­tor through prac­tic­al train­ing, de­mon­stra­tions and com­pre­hens­ive con­sult­ing ser­vices for the plan­ning and con­struc­tion of nearly zero-en­ergy build­ings (NZEB) with re­new­able en­er­gies, based on the Pass­ive House concept.

​COM­PLETED | The aim of the IEE-fun­ded EuroPHit pro­ject was to es­tab­lish cri­ter­ia and cer­ti­fic­a­tion op­tions for highly en­ergy-ef­fi­cient re­fur­bish­ments in line with the En­erPHit stand­ard which have to be im­ple­men­ted gradu­ally over a longer peri­od of time. This was achieved through new soft­ware tools, pi­lot pro­jects and train­ing for plan­ners and trades­people. The act­ors in­volved (in­clud­ing mu­ni­cip­al­it­ies, fin­an­cing in­sti­tu­tions and man­u­fac­tur­ers) were net­worked to im­prove col­lab­or­a­tion. At the same time, the use of Pass­ive House com­pon­ents in re­fur­bish­ments was pro­moted in a tar­geted man­ner.
