32nd AIVC Conference " Towards Optimal Airtightness Performance", Brussels, Belgium, 12-13 October 2011

At the end of 2010, two manufacturers have commissioned an independent engineering firm to carry out a cost-benefit analysis of air-tightness in ventilation. The study report uncovers the clear return of investment in class C air-tight ventilation systems in Belgium.
The study comprises:

  • The composition of a detailed spreadsheet with the result of the energy cost savings and additional investment cost;
  • The application of the spreadsheet to three Belgian cases (the renovation of a hospital wing, a nursing home and an office building);

The simulations show that the total energy consumption linked to ventilation can be reduced by as much as 30% with a break-even-point between 2 and 3 years.
