net­Zero  dis­tricts – in­nov­at­ive solu­tions for CO2-free build­ing re­fur­bish­ment

New ap­proaches are needed to make Ger­many’s build­ing stock cli­mate-neut­ral. Seri­al re­fur­bish­ment us­ing in­dus­tri­ally pre­fab­ric­ated com­pon­ents that meet the En­erPHit Stand­ard is a key solu­tion.

out­PHit - en­ergy ret­ro­fit­ting with pre­fab­ric­ated ele­ments

Seri­al re­fur­bish­ment can be eco­nom­ic­ally suc­cess­ful if as many build­ings as pos­sible of the same type in an en­semble with reg­u­larly struc­tured facades are en­ergy-ef­fi­cient re­fur­bished. Qual­ity as­sur­ance in plan­ning and ex­e­cu­tion is there­fore par­tic­u­larly im­port­ant for seri­al re­fur­bish­ment with pre­fab­ric­ated ele­ments.

Seri­al en­erPHit re­fur­bish­ment 

Seri­al re­fur­bish­ment aims at mass-pro­du­cing re­fur­bish­ments through in­dus­tri­al pre­fab­ric­a­tion and ac­cel­er­ated con­struc­tion times. Net­Zero can be achieved when re­fur­bish­ing to KfW EH and en­erPHit. This leads to such low elec­tri­city de­mand that the an­nu­al con­sump­tion can be covered by a roof-top PV in­stall­a­tion.

out­PHit: 3 Pi­lots in Gree­ce [Stre­am­li­ned Re­no­va­ti­on / 3D Ven­ti­la­ti­on De­sign]

My con­tri­bu­ti­on in the Out­PHit pro­ject was the three di­men­sio­nal de­sign of the ven­ti­la­ti­on sys­tem, the im­ple­men­ta­ti­on of the PHPP in so­me ca­se stu­dies, as well as the im­ple­men­ta­ti­on of the post mo­ni­to­ring of the ca­se stu­dies. De­sign the post mo­ni­to­ring equip­ment ac­cor­ding to the me­cha­ni­cal fa­ci­li­ties of each buil­ding, or­de­ring the equip­ment and in­stal­ling it to each buil­ding in or­der to mea­su­re the con­sump­ti­on and the in­ter­nal air qua­li­ty of each ca­se stu­dy.

One-Stop-Shop and Pre­fa­bri­ca­ti­on for Fast and Re­lia­ble Re­tro­fits from a Sin­gle Sour­ce

In this con­tri­bu­ti­on, the ro­le of one-stop-shops (OSS) in the re­tro­fit pro­cess for fast and re­lia­ble all-in-one so­lu­ti­ons is ex­plai­ned. The ran­ge of an OSS can in­cor­po­ra­te on­ly so­me or even all ser­vices of a de­ep re­tro­fit from the de­ci­si­on pha­se to a turn­key buil­ding. The pros, es­pe­ci­al­ly in com­bi­na­ti­on with pre­fa­bri­ca­ti­on, and the cons are shown as well.

out­PHit: Is It Pos­si­ble to Re­ach En­er­PHit Even in the High Al­pi­ne Re­gi­on?

It may be hard to reach En­erPHit even in the high alpine re­gion, but it is worth it in any case due to the in­creased liv­ing com­fort the max­im­um re­duced heat­ing re­quire­ment, ex­pand­ing the li­fe­cycle of the build­ing to its max­im­um, sav­ing a lot of gray en­ergy. Spe­cif­ic­ally shown, it also al­lows to max­im­ize the over­all num­ber of house­holds sup­plied with 100% re­new­able dis­trict heat­ing.
