In ad­di­tion to Pass­ive House design and Pass­ive House cer­ti­fic­a­tion, he also fo­cuses on thermal build­ing and plant sim­u­la­tion. His daily work looks at the safest and most eco­nom­ic­al ways of achiev­ing the Pass­ive House Stand­ard with re­new­able en­ergy sys­tems for large res­id­en­tial and non-res­id­en­tial build­ings. With the con­struc­tion of his own wooden Pass­ive House with elec­tri­city stor­age, to­geth­er with Di­eter Herz, he shows his con­vic­tion: "My Pass­ive House Plus is my con­tri­bu­tion to the en­ergy trans­ition and my fin­an­cial se­cur­ity for the fu­ture".

An­dreas Miller
Freiberu­f­lich­er En­er­gieberater und Ar­chitekt

An­dreas stud­ied Busi­ness and ar­chi­tec­ture in Würzburg. Fol­low­ing his stud­ies he widened his know­ledge at EZA! in Kempten be­com­ing an en­ergy con­sult­ant and Pass­ive House de­sign­er. An­dreas has also vo­lun­teered in re­gion­al en­ergy ini­ti­at­ives and fund­ing pro­jects (e.g. CO²­Con­tra). Since 2005 he has been work­ing as a freel­ance en­ergy con­sult­ant and ar­chi­tect. Eco­nom­ic and sus­tain­able build­ing and life are not a con­tra­dic­tion and re­nun­ci­ation.

Jes­sica Grove-Smith
Pass­ive House In­sti­tute

Jes­sica Grove-Smith gradu­ated with a mas­ter’s de­gree in phys­ics (MPhys) from the Uni­versity of Sus­sex in Eng­land. She has been part of the re­search team at the Pass­ive House In­sti­tute in Darm­stadt since 2008. Her re­spons­ib­il­it­ies range from sta­tion­ary and dy­nam­ic en­ergy de­mand mod­el­ling, cli­mate data for the PHPP and hy­gro­therm­al sim­u­la­tions of in­di­vidu­al build­ing com­pon­ents. The ap­plic­a­tion of the Pass­ive House concept for in­door swim­ming pools has also been a ma­jor fo­cus of her work, as well as con­tri­bu­tions to the re­new­able primary en­ergy as­sess­ment meth­od has been in­tro­duced for the new Pass­ive House classes.

Wolfgang Hasper
Pass­ive House In­sti­tute

Wolfgang Hasper has been a sci­ent­ist at the Pass­ive House In­sti­tute since 2005, fo­cus­ing on build­ing mon­it­or­ing, pro­ject con­sult­ing, as well as edu­ca­tion and train­ing.  Be­fore join­ing PHI in 2005, he trained as an ar­chi­tect and has gained broad ex­per­i­ence in prac­tic­al con­struc­tion, ran­ging from his own work as a car­penter and lock­smith to site su­per­vi­sion on be­half of an ar­chi­tect.

He con­tin­ues to be in­volved in a num­ber of con­sult­ing and re­search pro­jects, for which on-site qual­ity as­sur­ance is an im­port­ant part of the work. Cur­rent chal­lenges in­clude the de­vel­op­ment of sim­pli­fied tech­niques for post-oc­cu­pancy build­ing per­form­ance mon­it­or­ing. This in­volves us­ing spe­cial­ist meas­ur­ing equip­ment and data eval­u­ation pro­ced­ures to make sys­tem­at­ic per­form­ance eval­u­ations and op­tim­isa­tions more ac­cess­ible for de­sign­ers and build­ing own­ers world­wide.

He has worked as a re­search­er at the Pass­ive House In­sti­tute since 1998 where he co­ordin­ated the Re­search and Meas­ure­ment group.Søren primar­ily fo­cuses on mon­it­or­ing build­ings built to the Pass­ive House Stand­ard, both for new con­struc­tion and ret­ro­fits. He has au­thored many re­search re­ports on a vari­ety of dif­fer­ent build­ing types such as res­id­en­tial, schools and day­care cen­ters, factor­ies, of­fice build­ings and in­door swim­ming pools. Søren is also a spe­cial­ist in air­tight­ness and has worked on pub­lic­a­tions for air­tight­ness meas­ure­ment. He is a cer­ti­fied test­er and a mem­ber of the aso­ci­ation for air­tight­ness in build­ings (FLiB).
