Return on Investment (ROI) Calculation and Examples
Calculating the ROI for green insulated siding involves comparing the initial cost with the cumulative savings over the material’s lifespan. This lifespan varies depending on the material; fiber cement can last 50 years or more, while some composite materials may have a shorter lifespan of 20-30 years.
Let’s consider a hypothetical example: A homeowner invests $12,000 in engineered wood siding with an R-value of 6. Assume annual energy savings of $500 due to improved insulation and a reduced maintenance cost of $100 per year. Over a 25-year lifespan, the total savings would be ($500 + $100) * 25 = $15,000. Therefore, the ROI would be ($15,000 – $12,000) / $12,000 = 0.25 or 25%. This is a simplified example; a more accurate ROI calculation would involve factoring in the discount rate (the time value of money) and potential changes in energy prices over time. However, it illustrates the potential for a significant return on investment with green insulated siding. Similar calculations can be performed for other materials, considering their respective lifespans, R-values, and maintenance requirements to determine their individual ROI.
