Methodological approach for calibration of building energy performance simulation models applied to a common “measurement and verification” process

Abstract: A big challenge for energy savings performance contracting projects is the transparent and reliable determination of the energy consumption before and after retrofitting. This process, the so called “measurement and verification” (M&V) process, can be performed by means of calibrating simulation models with measured data, e.g. the energy bill data. There are guidelines for reporting and conducting this procedure. According to reports from case studies, it seems that they are carried out using several diffe… Show more

“…Where possible, input data from the case study site survey were used to inform model inputs to increase the accuracy of the model, as recommended by Park, Norrefeldt, Stratbuecker, Jang, and Grun (2013) and Lee, Lam, Yik, and Chan (2013). Estimates of inputs that could not be obtained from a survey were based on typical assumptions (listed in Table 1).…”

“…Parametric evaluation of the building models was conducted using jEPlus software (version 1.7.2), an open-source parametric analysis tool specifically designed for Energy Plus [71] that provides flexible and structural analysis opportunities and smooth operations [81]. The tool has been used in similar investigations to determine sensitivity or optimize energy systems [82,83].…”

“…In this study, a cloud computing platform for real-time measurement and verification of energy saving performance is created based on the M&V methodology and integrating of PSO algorithm, java programming language, and cloud computing techniques. While baseline models are applied automatically for pre-installation and real-time energy saving performance is calculated automatically after postinstallation, the cloud computing platform reduces the time Baseline data should be established because energy consumption in the pre-installation period (i.e., baseline period) cannot be measured by instruments after energy conservation measures (ECM) have been implemented [6]. Therefore, adjustments (A) to the baseline data are required to determine the energy consumption of the equipment and systems during the baseline period (BP) and the energy consumption during the post-installation period (reporting period (RP)) under the same operating conditions [7] The amount of savings (S) can be calculated as shown in (1).…”
