In commercial buildings it is economically viable to choose a DCV system in order to increase the comfort and decrease the energy use by up 50%. A DCV system achieves the highest comfort with the lowest possible operating energy.
In Franceso´s work four models were considered in the analysis (CAV, VAV, DCV, DCV with class 1) and for all of them were evaluated the energy to reach the same indoor temperature set points. The last model was built to increase the comfort inside the zones. The models were coupled as CAV-DCV and VAV-DCV in order to evaluate the benefits. Results show an overall reduction of approximately 50% for CAV to DCV and 40% for VAV to DCV.
These findings are based on the master thesis and presentation by Francesco Errico which will be available for download in upcoming weeks on our website.
