Get your Life-Cycle Assess­ment done eas­i­ly for DGNB, pow­ered by BIM
automa­tion. You can also use sim­ple Bill-of-mate­ri­als Excel, an Ener­gy
Mod­el or man­u­al input to opti­mize the LCA work. One Click LCA is also
inte­grat­ed with your local data. 

Life-Cycle Assessment (LCA) is required to achieve credits in DGNB certification.

One Click LCA makes get­ting an LCA for DGNB easy, intu­itive and time-effi­cient. You only need to provide your project’s bill of mate­ri­als into the easy to use cloud ser­vice, and you get the results accord­ing to the DGNB require­ments. The process can be auto­mat­ed with Build­ing Infor­ma­tion Mod­el (BIM), or oth­er mate­ri­als data sources. With the added ben­e­fit of using a web-based inter­face, you can involve any peo­ple required on the LCA to col­lect all the data seam­less­ly.

Life-Cycle Assessment in DGNB

  • Life-cycle assess­ment has been grow­ing in impor­tance as a new frame­work and analy­sis tool for sus­tain­abil­i­ty pro­fes­sion­als to ana­lyze the envi­ron­men­tal impacts of the given project.
  • Life-cycle assess­ment quan­ti­fies the impacts in var­i­ous dif­fer­ent envi­ron­men­tal impact cat­e­gories, includ­ing the Car­bon Foot­print or C02 foot­print.
  • Automat­ing LCA from your exist­ing data makes this a very cost-effi­cient and pow­er­ful analy­sis, where the frame­work itself can be lever­aged to opti­mize projects and make bet­ter design deci­sions.

We have your local data

Our team of LCA experts work tire­less­ly to inte­grate all the qual­i­fy­ing data and EPDs into our exten­sive data­base. This way One Click LCA always allows you to use your local data.


Ökobau.dat is a Ger­man data­base for con­struc­tion mate­ri­als and build­ing ser­vices made avail­able by the Fed­er­al Insti­tute for Research on Build­ing, Urban Affairs and Spa­tial Devel­op­ment (BBSR). The aim of the data­base is to provide har­mo­nized data for envi­ron­men­tal assess­ments of build­ings and dif­fer­ent con­struc­tion mate­ri­als, serv­ing all archi­tects, plan­ners and LCA prac­ti­tion­ers who  make life-cycle assess­ments in the build­ing sec­tor.

This is the solu­tion of choice for cer­ti­fi­ca­tion pro­fes­sion­als and con­struc­tors to make projects go smooth­ly and get qual­i­ty results. If you have a Build­ing Infor­ma­tion Mod­el, the mate­ri­als data can be parsed auto­mat­i­cal­ly with the ground break­ing One Click LCA solu­tion.

Latest version of Ökobau.dat is available with additional EPD data from IBU

The con­struc­tion mate­ri­als LCA data­base has also been updat­ed with lat­est ver­sion of the Ökobau.dat as well as with sig­nif­i­cant addi­tion­al EPD data from e.g. IBU. Each dat­a­point has under­gone a rig­or­ous qual­i­ty assur­ance process by our LCA engi­neers. The datasets are avail­able for users of DGNB (Ger­man and Inter­na­tion­al ver­sions) as well as for users of LEED, BREEAM and oth­er appli­ca­tions.
