Sample Problem: Value Index Calculation - HVAC System
Example
Problem Statement: An owner is choosing between two HVAC systems for a new office building. System A costs $500,000 and has a functional score of 80 (based on efficiency, noise, and maintenance). System B costs $750,000 and has a functional score of 95. Calculate the Value Index for both to determine the better investment.

Sample Problem: Lifecycle Cost Analysis (LCCA) - Flooring Selection
Example
Problem Statement: A hospital is choosing flooring for its corridors (10,000 m\textsuperscript). Option X (Vinyl) costs $30/m\textsuperscript to install, lasts 10 years, and costs $5/m\textsuperscript annually to clean/wax. Option Y (Terrazzo) costs $120/m\textsuperscript to install, lasts 30 years, and costs $1/m\textsuperscript annually to clean. Using a 30-year study period and ignoring the time value of money (discount rate = 0%) for simplicity, which option has the lowest lifecycle cost?

Key Takeaways
- Value vs. Cost Reduction: Value engineering is not cost-cutting. Cutting costs without maintaining function reduces value. True VE either maintains function while lowering cost, or increases function while keeping costs identical.
- Lifecycle Perspective: The vast majority of a building's cost (up to 75-80%) occurs during its operating life, not its construction. Initial capital costs are often a poor metric for long-term value.
