The Con­fer­en­ce will take place... now live from the stu­dio in Wup­per­tal and on­line


In light of the rising num­ber of in­fec­tions, es­pe­cially in Wup­per­tal and the sur­round­ing area, and in tak­ing re­spons­ib­il­ity for the health of all par­ti­cipants, the Pass­ive House In­sti­tu­te has de­cided to broad­cast the first part of the con­fer­en­ce live from the stu­dio in Wup­per­tal. Par­ti­cipants can join on­line.

To en­sure the glob­al Pass­ive House com­mu­nity can cel­eb­rate this mile­stone year to­geth­er with PHI, without risk in-per­son event tick­ets will auto­mat­ic­ally be changed to on­line-only tick­ets and the dif­fer­en­ce will be re­fun­ded.

The pro­gram will take place as planned, with all lec­tures be­ing presen­ted on­line. The open­ing plen­ary, as well as the 30th birth­day cel­eb­ra­tion of the first Pass­ive House, the 25th an­niversary of the Pass­ive House In­sti­tu­te, and the present­a­tion of the Pass­ive House Award 2021 will also be held on­line.

The 25th In­ter­na­tion­al Pass­ive House Con­fer­en­ce, in­clud­ing the ON­LINE Pass­ive House Ex­hib­i­tion, will take place on­line with live stream from Wup­per­tal from 10 to 12 Septem­ber 2021 and on­line on 14 and 15 Septem­ber 2021.

An ex­cit­ing con­fer­en­ce is wait­ing for you

On the one hand, there will be in­ter­est­ing con­tri­bu­tions on lar­ger pro­jects such as non-res­id­en­tial build­ings or multi-storey res­id­en­tial con­struc­tions built in Pass­ive House Stand­ard. On the oth­er hand, prac­ti­tion­ers are in­creas­ingly con­cerned with either ad­di­tion­al sus­tain­ab­il­ity as­pects or eco­lo­gic­al ma­ter­i­als for Pass­ive Houses or En­erPHit mod­ern­isa­tions. They also deal with solu­tions for pre­fab­ric­ated con­struc­tion and ren­ov­a­tion con­cepts for highly ef­fi­cient new build pro­jects and ren­ov­a­tions. An im­port­ant part of the solu­tions is also the train­ing and know­ledge trans­fer for cur­rent and fu­ture plan­ning and con­struc­tion staff, but also the suc­cess­ful com­mu­nic­a­tion of the Pass­ive House prin­ciples to loc­al au­thor­it­ies or build­ing own­ers.
