Sus­tain­ab­il­ity and Re­new­ables

Sus­tain­ab­ilty and Re­new­able En­ergy Sup­ply

Sat­urday, 4 May 2019, 9:00 am, Großer Saal (ground floor), sim­ul­tan­eous trans­la­tion in­to Eng­lish


The term “Systems Engineering” can sometimes sound boring and opaque, but it will be a crucial feature of our future buildings, cities and societies. The Passive House Institute has already taken a “Systems Engineering Approach” to the new PER standard, where the inclusion of renewable energy potential and generation are accounted for in building performance. In this session the details of the PER system and the successful integration of Passive House buildings with local renewable energy production will be discussed.

Wholistic design philosophies, and the need to account for the entire life-cycle of a building, are a significant topic across the globe and are already being accounted for in many business’s annual sustainability reports and this important topic will also be discussed in this session. This session also features a lecture delving into the social, as well as environmental, aspects of energy efficient buildings and again emphasises the fact that Passive House buildings have positive benefits to a number of societal indicators.

PER and Pass­ive House: Dream Team

Ben­ja­min Krick
  Re­new­able en­ergy is only avail­able to a lim­ited ex­tent. The Pass­ive House with its low en­ergy re­quire­ment com­plies with this lim­it­a­tion. This is es­pe­cially true in winter, when little sol­ar en­ergy is avail­able and there is a high de­mand for heat. In the fu­ture there will be a need for short- and long-term en­ergy stor­age in or­der to avoid sup­ply gaps. However, the stor­age losses are con­sid­er­able, which res­ults in an­oth­er ar­gu­ment for highly ef­fi­cient build­ings. The en­ergy that is not needed in winter does not have to be stored with high losses. The concept of Primary En­ergy Re­new­able (PER), ac­cord­ing to which Pass­ive Houses can be ev­al­u­ated, auto­mat­ic­ally takes these losses in­to ac­count.

Life cycle ana­lys­is of res­id­en­tial build­ings of dif­fer­ent con­struc­tion meth­ods
Ste­phan Leit­schuh
  The life cycle ana­lys­is of a single-fam­ily house us­ing vari­ous designs provides the cli­ent with an im­port­ant basis for de­cision-mak­ing. The ana­lys­is ex­am­ines the com­plete life cycle from man­u­fac­tur­ing, to the use phase, to the dis­pos­al phase of build­ings in heavy and light­weight con­struc­tion. Each design has spe­cif­ic strengths.  The res­ults de­mon­strate the im­port­ance of en­ergy-ef­fi­cient design in the life cycle of the build­ing. Ul­ti­mately, the eco­lo­gic­al bal­ance of the build­ing can be im­proved, above all, through a long ser­vice life. This re­quires a high-qual­ity ex­e­cu­tion and a thor­ough plan­ning of the build­ing from the start.
