Event Description

The 28th In­ter­na­tion­al Pass­ive House Con­fer­en­ce will take place in the "Haus der Technik" in Es­sen, Ger­many, on 24 - 25 April 2026.  Un­der the motto "Driv­ing Trans­form­a­tion with En­ergy Ef­fi­ciency!," the con­fer­en­ce will again bring to­geth­er hun­dreds of en­thu­si­ast­ic, in­nov­at­ive build­ing ex­perts from all over the world. To­geth­er the organisation will take fur­ther steps to­wards our goal of a cli­mate-friendly and fu­ture-proof build­ing stock!

Moreover, the organisation would like to take this op­por­tun­ity to cel­eb­rate the 30th an­niversary of the Pass­ive House In­sti­tu­te and the 35th birth­day of the first Pass­ive House in Darm­stadt-Kranich­stein. 

Workshops - 
Deep­en your ex­pert know­ledge with the fol­low­ing work­shop of­fers for Thursday, 23 April 2026 (Haus der Tech­nik in Es­sen, Ger­many). The work­shops are re­cog­nised as fur­ther edu­ca­tion. If you are in­ter­es­ted, you will re­ceive train­ing cred­it points for your par­ti­cip­a­tion (ex­cept for the ex­tra work­shop on roof ret­ro­fit­ting).

Work­shop 1: Lüf­tung­skonzepte in der Sani­er­ung (in Ger­man)

Thursday, 23 April 2026, 9.30 - 12.00
Loc­a­tion: Haus der Tech­nik (Hol­le­str. 1, 45127 Es­sen)
Lan­guage: Ger­man

Work­shop 2: More than just in­su­la­tion - a life-cycle per­spect­ive on build­ings | with MEET

Thursday, 23 April 2026, 1.00 - 3.30
Loc­a­tion: Haus der Tech­nik (Hol­le­str. 1, 45127 Es­sen)
Lan­guage: Eng­lish

Life cycle as­sess­ments are more than com­pli­ance tools: They high­light the im­pact of high-ef­fi­ciency design meas­ures and sup­port bet­ter de­cision-mak­ing throughout the plan­ning pro­cess. The work­shop in­tro­duces the Pass­ive House In­sti­tu­te's meth­od­o­logy which fo­cuses on the en­ergy de­mand and green­house gas emis­sions as­so­ci­ated with con­struct­ing and op­er­at­ing a build­ing. In the prac­tic­al part of the work­shop, par­ti­cipants will work hands-on with the Man­u­fac­tur­ing En­ergy Ev­al­u­ation Tool (MEET) to ana­lyse and ev­al­u­ate ma­ter­i­als and build­ing com­pon­ents. This makes it easy to see how both man­u­fac­tur­ing and op­er­a­tion­al en­ergy - as well as life cycle green­house gas emis­sions - can be re­duced over the life cycle.

Work­shop 3: Sum­mer com­fort - pas­si­ve and ac­ti­ve meas­ures

Thursday, 23 April 2026, 4.00 - 6.30
Loc­a­tion: Haus der Tech­nik (Hol­le­str. 1, 45127 Es­sen)
Lan­guage: Eng­lish

In the wake of glob­al warm­ing, the top­ic of pre­vent­ing over­heat­ing in build­ings is be­com­ing in­creas­ingly im­port­ant, es­pe­cially since high in­door tem­per­at­ures are not only a ques­tion of com­fort, but can also have a sig­ni­fic­ant im­pact on health. A build­ing's design has a fun­da­ment­al in­flu­en­ce on the thermal com­fort achieved in sum­mer and its ro­bust­ness and re­si­li­en­ce against the risk of over­heat­ing dur­ing heat waves. PHPP and design­PH are use­ful plan­ning tools for the op­tim­isa­tion pro­cess dur­ing the design phase. Due to rising out­door tem­per­at­ures, act­ive cool­ing is be­com­ing in­creas­ingly ne­ces­sary also in cli­mates where this was pre­vi­ously not needed. In en­ergy-ef­fi­cient build­ings, this can be achieved in a cli­mate-friendly man­ner with very low en­ergy con­sump­tion and should be taken in­to ac­count by de­sign­ers as part of their for­ward-look­ing plan­ning. This work­shop will dive in­to sum­mer com­fort design strategies for new build­ings and ret­ro­fits, in­clud­ing prac­tic­al guid­ance for pass­ive cool­ing meas­ures and how to mod­el this in PHPP, stress test­ing re­si­li­ent design and re­com­mend­a­tions for ef­fi­cient tem­per­ing and cool­ing sys­tems. The con­tent is in­ten­ded for build­ings in cool-tem­per­ate and warm-tem­per­ate cli­mates.

Ex­tra work­shop: Suc­cess­fully ret­ro­fit­ting roofs (in co­op­er­a­tion with FLiB e.V.) (in Ger­man)

Vis­it ex­cit­ing Pass­ive House pro­jects in Es­sen and the sur­round­ing re­gion!
