Building Energy Performance Certificate—A Relevant Indicator of Actual Energy Consumption and Savings?

Abstract: A building energy performance gap can be illustrated as the difference between the theoretical (methodologically defined) and the actual energy consumption. In EU countries, Energy Performance Certificates are issued when buildings are constructed, sold, or leased. This information is the first step in order to evaluate the energy performance of the building stock. In Serbia, when issuing an energy certificate, the adopted national methodology recognizes only energy consumption for heating. The main purpose of… Show more

“…Since the beginning of the global catastrophe in the 1970s, power generation has been gaining traction, and more and more scientists are studying it to reduce energy consumption at home and achieve some achievements [9,10]. Since the inception of BIM technology, BIM heat wave has appeared in the development of the world, and the use of BIM technology in every cycle of home life has been popular.…”

“…Alongside these recent analyses, there is extensive evidence from across Europe regarding the difference between EPC-modelled energy use and actual metered energy use (for example, van den Brom et al, 2018;Szulgowska-Zgrzywa et al, 2020;Anđelković et al, 2021). There are several common findings in this research.…”

“…The seasonal efficiency of heating appliances and the water heater efficiency can be used in the case of utilization in a system, the importance of which has been highlighted by Calero-Pastor et al [19], and for the calculation of building certificates [20,21]. As additional adoption of the labeling methodology, Adene is currently evaluating the implementation of the energy labeling methodology for existing appliances in the phase of certification of Portuguese buildings.…”

“…Different options for space heating systems and water heaters can be found in the literature, including heat pumps and hybrid systems, a combination of solar thermal or PV systems with other generation systems and improvement of control strategies [7][8][9][10][11][12]. Awareness can be raised by providing information about the expected performance with an energy label [1,[13][14][15][16][17][18][19][20][21][22], or by providing information about the actual energetic performance [23][24][25]. In the second case, information on consumption can reduce consumption, on average, from 4% to 20% depending on the application [23][24][25].…”
