Urban Vertical Green 2.0

Stake­hold­er Work­shop – facade greening:

It is get­ting hot­ter in cities world­wide. We are look­ing for ways to reduce the heat­ing of cities. Due to the dense­ly built-up areas of cities and the asso­ci­at­ed high degree of sur­face seal­ing, espe­cial­ly greened build­ings are an effi­cient way of cool­ing the city. Regard­ing an improve­ment of the micro­cli­mate near the ground, espe­cial­ly facade green­ing.
In addi­tion to improv­ing the micro­cli­mate, facade green­ing has many oth­er pos­i­tive effects on the urban envi­ron­ment, such as ther­mal insu­la­tion, noise reduc­tion, wildlife habi­tat, aes­thet­ic aspects, upgrad­ing and pro­tect­ing the build­ing struc­ture or pol­lu­tant fil­ters.
The sub­ject of green­ing facades is noth­ing new — the over­growth of build­ings with ivy was already used in ancient times. There are dif­fer­ent types of facade green­ing today — ground-based and facade-based. But what unites both sys­tems is cur­rent­ly a rel­a­tive­ly rare appli­ca­tion in urban areas com­pared to green roofs.
In the next few years, the build­ing reg­u­la­tions in many large cities will pre­sum­ably change towards the enforce­ment of the green­ing of build­ings.
Espe­cial­ly when it comes to green­ing facades, there are many stake­hold­ers affect­ed, who are includ­ed in the course of an erec­tion. But what unites or sep­a­rates the dif­fer­ent inter­est groups? What are com­mon start­ing points and how can pos­si­ble points of con­flict be defused and resolved?

The main focus of this ses­sion deals with the top­ic of “Irri­ga­tion of Ver­ti­cal Green”. With­in a research project, called “Urban Ver­ti­cal Green”, we are look­ing for dif­fer­ent approach­es, while using some stake­hold­er-que­ston­airs, to reach a tar­get­ed and effi­cient irri­ga­tion of ver­ti­cal green. 
Dur­ing the work­shop we are plan­ning to iden­ti­fy weak­ness­es of exist­ing sys­tems (con­trol sys­tem and sup­ply engi­neer­ing), to dis­cuss dif­fer­ent solu­tion approach­es for a resource sav­ing irri­ga­tion (using rain and grey water), to iden­ti­fy inter­faces, devel­op­ment and research requirements.

Due to the large num­ber of par­tic­i­pants the online-work­shop is designed, that a par­tic­i­pa­tion would actu­al­ly just be nec­es­sary on one of the two days, because the same top­ic will be dis­cussed on each day. If you would be inter­est­ed to par­tic­i­pate on both days, it would be pos­si­ble of course (Please mind the lan­guage in which the ses­sions will be held).
A par­tic­i­pa­tion is pos­si­ble on 24th of Sep­tem­ber 2020 (02:00 p.m. — 08:30 p.m. -> ses­sion in Ger­man) or 25th of Sep­tem­ber 2020 (09:00 a.m. — 12:30 p.m. -> inter­na­tion­al ses­sion in english).



  • Reg­is­tra­tion: from Feb­ru­ary 01st, 2020
  • Con­gress: 24–25.09.2020
  • Which stake­hold­ers are affect­ed by facade greening?

  • What reser­va­tions and con­cerns are there about facade greening?

  • What are the main rea­sons for the rel­a­tive­ly rare use of green facades in urban areas?

  • What qual­i­ties must facade green­ing pos­sess in order to expe­ri­ence a high­er degree of acceptance?

  • Which inten­si­ty of facade green­ing do the dif­fer­ent stake­hold­ers find appropriate?

  • What can be done to force and imple­ment facade green­ing in urban areas?

  • What influ­ence do dif­fer­ent design qual­i­ties of facade green­ing have on the accep­tance of dif­fer­ent stakeholders?

  • Which pos­si­ble (non-) prof­itable busi­ness mod­els can be devel­oped to facil­i­tate the use of green facades in the city?


We are looking for:

For the project “Urban Ver­ti­cal Green 2.0” we are search­ing for a max­i­mum of 20 participants/stakeholders of all kinds who want to gain knowl­edge and con­tribute to the matter.
