Towards the integration of monitoring systems to support the evaluation of nearly Zero Energy Buildings through Key Performance Indicators

Monitoring systems are one of the pivotal diagnosis tools for the analysis of the energy performance in buildings. They provide on-site information and support the decision making process. Moreover, monitoring systems allow the calculation of energy and comfort indicators, despite, large buildings do not provide a single sensor network. So, with the aim of integrating multiple monitoring systems to support the energy assessment, this paper presents a combination of thereof into a nearly Zero Energy Building in order to evaluate a set of Key Performance Indicators. This study demonstrates the importance of monitoring systems and how they support the automatic calculation of aggregated values in terms of indicators to determine the building performance, thus detecting the malfunctioning of the facilities so as to reduce the energy consumption and CO2 emissions.
