Many of the energy efficiency technologies could be employed in both the domestic and non-domestic arena, so the information on payback periods provided in response to question 1088 may be relevant to some smaller non-domestic applications. However, information on the payback periods in non-domestic properties are much more difficult to determine because of the likely significant variation in scale, cost and use. The Department does not hold this information.

The Department does not hold information on the internal rate of return, as this information would be specific to each company and installed measure.
The private cost per kilogram of carbon dioxide not emitted (avoided) under a CERT regime can be determined for a range of technologies from the information provided in the following tables 1 and 2. The cost can be obtained by dividing the total cost for the measure, shown in table 2, by the relevant carbon dioxide savings shown in table 1 (multiply the figures shown in table 1 by 1,000 to obtain kilograms of carbon dioxide). The Department does not hold this information for circulator pumps.
