However, here are the steps for using life cycle cost analysis to optimize MEP design decisions:
1. Define the scope of the analysis: This includes the system under investigation (e.g., HVAC, plumbing) and the period of analysis.
2. Identify alternative design options: This involves evaluating different designs in terms of the components that make up the system.
3. Establish the initial cost: This includes the upfront cost of purchasing and installing the system.
4. Analyze the operating costs: This involves determining the energy consumption and maintenance costs associated with each design option.
5. Calculate the life cycle costs: This is the sum of the initial cost and the operating costs over the period of analysis.
6. Compare the life cycle costs: Identify the design option with the lowest life cycle costs.
By following this process, life cycle cost analysis can be used to identify optimal MEP design decisions that balance initial costs with long-term operating costs.
