A novel ROM methodology to support the estimation of the energy savings under the Measurement and Verification protocol

This paper presents a novel Reduced Order grey box
Model (ROM) methodology, based on a Resistor-
Capacitor (RC) network, which supports the creation of
the baseline energy consumption and the estimation of
energy savings due to Energy Conservation Measures
(ECMs) under the Measurement and Verification
protocol. Within this scope, a description of the RC
network, including a calculation of the parameters’
needed to execute the ROM, are presented. This ROM
methodology is demonstrated on an educational building
located in Sant Cugat, Spain as part of the H2020
GEOFIT project. The results presented in this paper
demonstrate that the ROM is sufficiently accurate for the
creation of the baseline energy consumption and for
estimating the energy savings of different ECMs.
