Savings of around 50,000 metric tons of CO2 in the building management sector

Euro­pean cli­mate tar­gets are ambi­tious. The EU tax­on­o­my is a real­i­ty. Sig­nif­i­cant CO2 reduc­tion is essen­tial. With a share of 40% of total CO2 emis­sions, build­ing man­age­ment plays a cru­cial role. PAUL is pay­ing par­tic­u­lar atten­tion to exist­ing prop­er­ties and will save around 50,000 tons of CO2 over a ten-year period.

The focus of CO2 reduc­tion in build­ings is still very much on insu­la­tion, pho­to­voltaics and heat­ing tech­nol­o­gy. Here, the sav­ings poten­tial has now been large­ly exhaust­ed. For a long time, the ener­gy con­sump­tion caused by drink­ing water sys­tems and heat­ing net­works went unno­ticed. This con­trol sys­tem oper­ates intel­li­gent net­works and rais­es the ener­gy sav­ing poten­tials there. This prin­ci­ple already saves up to 20% ener­gy and thus CO2.

The GmbH has been work­ing on dig­i­tal­iza­tion and the cre­ation of smart grids in build­ings since 2017. More than 150,000 hous­ing units are already con­nect­ed and main­tained via the con­trol sys­tem. In 2021, well-known play­ers in the hous­ing indus­try have new­ly placed their bets on it or expand­ed their involve­ment. These include real estate investors and coop­er­a­tives as well as pri­vate and munic­i­pal hous­ing com­pa­nies. In total, this adds up to CO2 sav­ings of 50,000 tons over the total term.

 “The wide range of pos­si­bil­i­ties offered by PAUL are quick­ly con­vinc­ing. Espe­cial­ly in times of cli­mate change and the top­ic of EU tax­on­o­my, many of our cus­tomers see the poten­tial in how they can make their build­ings uncom­pli­cat­ed­ly tax­on­o­my-com­pli­ant. In addi­tion to the tech­ni­cal details, we also pro­vide sup­port in all admin­is­tra­tive mat­ters. This is well received and is the basis for a long-term, trust­ing collaboration.”

With its AI-based process, the con­trol sys­tem ensures a con­stant water tem­per­a­ture at the TWA that is above 55° Cel­sius, thus pre­vent­ing bac­te­r­i­al growth, espe­cial­ly of legionel­la. It also ensures per­ma­nent hydraulic bal­anc­ing, which ensures con­stant move­ment of the water. This reduces CO2 emis­sions by a rel­e­vant amount. Every­thing is con­trolled from the con­trol sta­tion. Here, the data is ana­lyzed and, if nec­es­sary, mea­sures are ini­ti­at­ed. A dig­i­tal twin of the drink­ing water sys­tem is cre­at­ed. The con­trol sys­tem doc­u­ments all data. This ensures legal cer­tain­ty vis-à-vis author­i­ties, which is a great ben­e­fit for oper­a­tors of res­i­den­tial complexes.

Maiko Dufn­er, Man­ag­ing Direc­tor says: “Less ener­gy required also means low­er costs. In addi­tion, the con­trol sys­tem still holds enor­mous poten­tial for mak­ing build­ings CO2 neu­tral. In this way, we cre­ate a win-win-win sit­u­a­tion for oper­a­tors, res­i­dents and the environment.”
