Toward building energy management: Electric analog modeling for thermal behavior simulation

Abstract

The most energy in buildings is used for space cooling and heating. Thus, the thermal analysis is necessary to reach thermal comfort and energy efficiency in buildings. In this paper, we present a thermal envelope modeling based on thermalelectrical analogy for thermal behavior simulation. The research object is a real platform inside our laboratory building in France. To illustrate this study, two thermal zone model represent two room of this platform, and they are surrounded by another thermal zones of laboratory building. Their parameters have been identified from envelope properties. Then, these models are implemented in a simple equivalent electric circuit, simulated and validated with measurement data.

Optimal Sizing of PV System Combined to Cooling Load Management Strategy towards Photovoltaic Self-Consumption in Buildings

“…A and B are state matrices depending on the resistances and capacitances. The detailed construction of a building thermal equivalent electrical model is described in [6,7].…”

“…Meanwhile the life cycle of PV modules is supposed to be equal to the studied period (30 years). Each of these cost functions is expressed in equations (5), (6) and (7).…”

Building Modelling Methodology Combined to Robust Identification for the Temperature Prediction of a Thermal Zone in a Multi-zone Building

“…Dang et al [24] presented a thermal envelope model based on the equivalent electrical circuit for the building optimal management. From 16 input parameters including thermal resistances and capacitances, the method of Morris was used to determine 8 non-influential inputs which were then fixed by their analytic values.…”
