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.
