Payback time of 7 years in real school building with demand controlled ventilation!

I got my hands on interesting master thesis from Juha Pasila from Finland about “Demand-controlled ventilation in school buildings”. Juha had the chance to monitor an old school with standard ventilation system with cooling for some period of time and he also obtained the results from monitoring after the building was refurbished with new mechanical ventilation system.

Juha evaluated also indoor air quality and temperature in the school with new ventilation system. In his master thesis he concluded that the new demand controlled system has decreased heating expenses and consumption up to 46,8% in heating energy and up to 72,8% in electrical energy. The payback time was calculated to seven years!
