The study of the impact of demand controlled ventilation in energy consumption of offices in Portuguese commercial buildings

摘要

This study presents an implementation of an application, using mathematical models, which allow to create virtual simulations to minimize energy consumption, thereby enabling an optimization of the energy efficiency of air handling equipment. The mathematical model was validated by laboratory experiments. An analysis of variation of the quantity of supply air of the system for three cities in different climatic conditions was performed. The analysis of energy consumption values for each city, show that the largest potential reduction of energy consumption can be seen to the city of Faro for the simulation of two occupants with a reduction of 39,84%.
