Reduced Maintenance

Buildings with mechanical equipment require maintenance and often have significant costs associated with these activities, whereas natural ventilation equipment is often maintenance-free or low-maintenance. The mechanical plant in a mechanically ventilated building will require a significant overhaul, refurbishment or even replacement in a 15-20 year timescale. In contrast, natural ventilation equipment typically lasts longer, and if there is a requirement for replacement of any equipment, it is relatively inexpensive – the weatherproof louvers, control system, ducts, and shafts are very unlikely to need replacement.
