A building manager is comparing the operating cost of the existing boiler to the purchase and operation of a new and more efficient boiler. The building manager discovers that although the upfront cost is significant, purchasing the new boiler would drastically decrease the cost of running and operating the system.

A building manager is comparing the operating cost of the existing boiler to the purchase and operation of a new and more efficient boiler. The building manager discovers that although the upfront cost is significant, purchasing the new boiler would drastically decrease the cost of running and operating the system. This exercise is called
A . life-cycle costing
B . value engineering
C . integrated design
D . life-cycle assessment

Answer: A
