Capital Investment: Energy Efficiency Upgrade

You are the controller of a 350-room hotel. The hotel's energy costs have risen 20% over the past three years, now totaling $1.2 million annually, or 4% of total revenue. The hotel's HVAC systems are original (15 years old) and inefficient. The engineering manager proposes replacing the HVAC system with a high-efficiency model. The new system costs $2.5 million and is expected to reduce energy consumption by 30%, saving $360,000 per year. It has a useful life of 15 years. The hotel's cost of capital is 8%. The owner is hesitant to invest due to the large upfront cost and the hotel's current debt load. The hotel's EBITDA is $8 million, and the owner is focused on improving cash flow. There are also government incentives: a tax credit of 10% of the investment and a rebate of $100,000 from the utility company. The hotel can finance the project with a 5-year loan at 5% interest, with monthly payments. The engineering manager argues that the new system will also improve guest comfort and reduce maintenance costs by $50,000 per year. The hotel's current maintenance costs for HVAC are $200,000 annually.

1. Perform a financial analysis of the HVAC replacement. Should the hotel proceed? Consider NPV, IRR, payback period, and cash flow impact.

Initial investment: $2.5M - tax credit (10% = $250K) - rebate $100K = $2.15M net cost. Annual savings: energy $360K + maintenance $50K = $410K. Over 15 years, with 8% discount rate, NPV = -2.15M + 410K * PV annuity factor (8%,15). PV factor = (1 - 1/1.08^15)/0.08 = 8.559. PV of savings = 410K * 8.559 = $3.509M. NPV = $1.359M. IRR: solve for r where 2.15 = 410 * PV factor. PV factor = 5.244. Using tables, IRR approx 18.5%. Payback: 2.15M / 410K = 5.24 years. With financing: loan $2.15M at 5% over 5 years, monthly payment = ? Monthly rate 0.05/12=0.004167, n=60. Payment = 2.15M * 0.004167 / (1 - (1.004167)^-60) = approx $40,600 per month, or $487K per year. Annual savings $410K, so net cash flow negative in first 5 years by $77K per year, but after loan paid off, positive $410K. However, the hotel's cash flow might be tight. But the NPV is positive and IRR > cost of capital, so financially viable. Also consider guest comfort and potential revenue increase. Recommendation: Proceed, but explore financing options to minimize cash flow impact. Perhaps negotiate a longer loan term or lease. The owner's concern about debt load can be mitigated by the savings and incentives.

2. How would you present this to the owner to gain approval? What non-financial factors should be highlighted?

Present a clear, concise business case. Start with the financials: show NPV of $1.36M, IRR of 18.5%, payback of 5.2 years, and the positive impact on EBITDA (increase of $410K per year after loan). Emphasize the government incentives and the net cost after credits. Address the debt concern: show that the loan payments are covered by savings after the first year? Actually, loan payments $487K vs savings $410K, so slightly negative, but the hotel can use the $410K savings plus the $50K maintenance savings to cover most of it; the net cash flow impact is -$77K per year for 5 years, which is manageable given EBITDA of $8M. Alternatively, propose a longer loan term (e.g., 7 years) to reduce annual payments. Non-financial factors: improved guest comfort (HVAC is a common guest complaint), reduced maintenance emergencies, environmental sustainability (marketing advantage), and compliance with potential future regulations. Also, the new system may increase property value. Highlight that delaying means continued high energy costs and potential breakdowns. Use a phased approach if needed: replace the most inefficient units first. Finally, assure the owner that you will monitor energy savings and report quarterly.
