When upgrading from VAC or CAV with an additional investment of 10%, the costumer could reach an annual saving, in both economic and energy terms, around 50% and this is given with a short payback period of less than 2 years.
The installation of an high-tech ventilation system with precise control of the indoor temperature would increase the facility value and would make energy category in accordance with class 1. This would affect also the indoor comfort conditions that would increased dramatically and consequently that would lead to increase of productivity. That means that the payback period could be further reduced.
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.
