Study period
Life Cycle Costing (BG 67/2016), written by David Churcher and Peter Tse and published by BSRIA in March 2016, defines study period as: ‘The time over which a life cycle costing model is constructed. It is usually measured in years but does not need to be, provided it is consistent with the discount rate. For analyses in this guide, the study period always starts at year 0, which represents ‘today’. Only costs and benefits that occur within the study period are included in the life cycle costing model. The Treasury Green Book (Appraisal and Evaluation in Central Government) suggests that 15-25 years would be a typical study period for a new building.’
