8.2 Life-Cycle Costs

Life-cycle costs need to be considered as well. For example, if it is decided that two guarded entrances will be provided, one for the visitors and one for the employees, they may cost more during the life of the building than a single well designed entrance serving everyone. Also, maintenance costs may need to be considered. For instance the initial costs for a CBR detection system may be modest, but the maintenance costs are high. Finally, if the rentable square footage is reduced as a result of incorporating robustness into the building, this may have a large impact on the life-cycle costs.
