Explanation of ROI Chart:

• The ROI Chart is a financial tool that compares the Capital Expenditure (CapEx) plus the Operating Expense (OpEx) of an Energy Allstar product to the CapEx plus OpEx of a product in the same class that complies with Minimum Energy Performance Standard (MEPS) over 10 years of operation.
• The Payback Period is the length of time that it takes for the stream of OpEx savings from an Energy Allstar purchase, to equal the additional CapEx needed to purchase the Energy Allstar rated equipment.
• For example, if the lines in the chart above cross at the mid-point between Year 1 and Year 2, then the payback is 1.5 years or 18 months.

Explanation of Return on Additional Capital:

The Return on Additional Capital is a financial ratio to assess the potential investment value of an Energy Allstar compliant purchase versus the purchase of less efficient equipment. The ratio is calculated by dividing the value of electricity savings of the Energy Allstar equipment, by the additional capital cost of the elite equipment purchased, expressed as a percentage.

Assumptions:

• All budget prices and costs are excluding GST, and exclude delivery, installation and commissioning as they are considered equivalent when comparing one product versus another.
• Default budget price for MEPS compliant product is 10% less than the Energy Allstar.
• HEPS is defined as the propsed MEPS levels in the recent consultation RIS, and default budget prices are 5% less than the Energy Allstar.
• Actual prices can be entered for a more precise financial comparison.
• Assume Site load profile is as per ARI – Standard 550/590-98 Integrated Part Load Value. Where NPLV = 0.01*COP100% + 0.42*COP75% + 0.45*COP50% + 0.12*COP25%.
• Operating hours are based on operating hours and adjustment factors published in Consultation Regulatory Impact Statement – Air Conditioners and Chillers, Equipment Energy Efficiency (E3) Program, February 2016.
• The calculations ignore the Time Value of Money.
• Electricity prices inflate at 2% per annum.
• Maintenance costs and other operating expenses (i.e. ancillary equipment) are not taken into account although when replacing older equipment with new equipment maintenance costs should be lower for a period and the maintenance costs of quality product should be lower than inferior product.
