Method for modelling space conditioning aggregated daily load curves: Application to a university building

Abstract:

Physically based load modelling methodologies have been widely developed and used because of their ability to pbkp_redict the energy load dynamic response. Most building energy programs pbkp_redict energy consumption and energy system performance through a whole building energy simulation as well as a global analysis of building thermal processes and heating, ventilation and air-conditioning (HVAC) system performance. A different approach is presented in this paper by introducing a new method for modelling the daily load profile of a group of air-conditioning systems. This method is based on the simulation of a single HVAC system, a set of end-use electrical measurements, and a detailed walk-through and energy audit. The basic methodology allows deducing the aggregated load of a group of space conditioning devices by the addition of the daily simulation of each individual physical system. As an application, the space conditioning daily demand curve of a university building is studied and results are presented. © 2010 Elsevier B.V. All rights reserved.
