It's long been recognised that the capital cost of a building, can be significantly smaller that the  building running costs and still smaller, than the overall cost of employing a member of staff, when considering salary, national and pension contributions. 

I was quoted a ratio of 1:10:100, by staff working for a large national contractor, when working  on a PFI bid for a local authority project, some years ago. This was comparing construction cost; running costs (maintenance and energy and water consumption); and staff costs, over the 25 year PFI contract period.

The article demonstrates the benefits of spending on good quality buildings, to increase staff satisfaction and productivity. 

As a Building Services Engineer, it is interesting to see that four out of the six important variables that improve occupant health are engineering aspects of building e.g. lighting, ventilation/air quality, thermal comfort and noise and acoustics. It demonstrates the important role engineers have in creating productive, healthy workplaces fit for the 21st Century.
