. In Great Britain, the new British Standard BS ISO 15686-5:2008 Buildings and constructed assets. Service life planning is currently being launched (September 2008). The life cycle costing standard and the additional Standardized method of life cycle costing for construction (SMLCC) provide an in-depth guide to life cycle costing, an area of increasing importance. The BSI explains that "the UK building industry recognizes that life cycle costing (LCC) is necessary and important, but confusion exists about the best method to realise the economic and environmental benefits of such costing".
