This paper details results from Life Cycle Cost (LCC) assessment of Mechanical and Electrical (M&E) services of a new build school project in Manchester. Building Information Modelling (BIM), Dynamic Simulation Modelling (DSM) and Building Cost Information Service (BCIS) running cost tools were employed to estimate the incurred costs over the life of the school and the LCC of different design specification options for lighting. Results indicate that the operational cost of M&E services is twice that of the capital expenditure and operational costs (energy, maintenance and replacement costs) contribute approximately 67% of the whole life value of the project. It also demonstrates how Construction 2025's 33% cost reduction target is achievable by spending only 6% more on M&E capital expenditure.
