Šiuo metu Europos Sąjungoje ypač daug dėmesio skiriama šiltnamio efektą sukeliančių dujų ir energijos vartojimo mažinimui. Pastatai čia atlieka svarbų vaidmenį, nes dėl jų susidaro apie 36 % viso ES išmetamo CO2 kiekio. Todėl didesnis pastatų energijos vartojimo efektyvumas yra esminis dalykas siekiant sumažinti jų poveikį aplinkai. Buvo atlikti tyrimai, kurių metu nustatyta, kad, nors pastatai projektuojami kaip energiškai efektyvūs ar beveik nulinės energijos, faktinis energijos suvartojimas A, A+ pastatuose gali viršyti net 1,5–2,5 karto, lyginant su deklaruotu energinio naudingumo sertifikate. Šis nesutapimas vadinamas energinio naudingumo spraga EPG (angl. Energy Performance Gap). Šiame darbe analizuojamos administracinio pastato EPG atsiradimo priežastys ir, remiantis faktiniais stebėsenos duomenimis, vertinama galimybė sumažinti atotrūkį tarp teorinių ir faktinių suvartojamų energijos kiekių. Nustatyta, kad analizuojamu atveju esminės EPG priežastys yra pastato ŠVOK sistemų valdymo neefektyvumas. The European Union nowadays is paying extra attention to global warming-causing gases and minimizing energy consumption. Here buildings play a big role; they make up about 36% of the whole EU‘s CO2 emissions. That is why the more effective building energy consumption is, the less it affects nature and global warming. A number of studies have found that although buildings are designed to be energy efficient or nearly zero energy, the actual energy consumption at A and A+ class buildings may even exceed 1.5–2.5 times what was declared in the energy performance certificate. This discrepancy is called the Energy Performance Gap, or EPG, for short. This paper analyzes the causes of administrative building EPG occurrence and, based on actual monitoring data, evaluates the possibility of reducing the gap between theoretical and actual energy consumption. Results of the analysis showed that the essential causes of the EPG are the inefficiencies of the building’s HVAC system management.
