On many sites throughout the UK and Ireland, active ventilation systems were installed to provide adequate dilution of potential permanent ground gas and VOC vapours within a construction. Due to advances in gas monitoring equipment, it is now apparent that many sites which have had active ventilation systems installed, do not actually require them. This has led to huge costs being absorbed by building owners for lengthy annual maintenance contracts which may not be required. By eliminating the requirement for the active ventilation system, this adds to improvements of carbon footprinting and sustainability credentials.
With the correct information, we can provide a report based on the original site investigation or maintenance data logs, which allow these systems to be disconnected. This offers monetary savings to the building owner in reducing on-cost of the active ventilation power and costly maintenance contracts which can be discontinued. There are also carbon cost savings due to the power savings.
