Cost Analysis¹
As part of the RETScreen Clean Energy Project Analysis Software, the Cost Analysis worksheet is used to help the user estimate costs (and credits) associated with the proposed case. These costs are addressed from the initial, or investment, cost standpoint and from the annual, or recurring, cost standpoint. The user can refer to the RETScreen Product Database for supplier contact information in order to obtain prices or other information required.
Cost Analysis Worksheet
The most cost effective installations of renewable, cogeneration or energy-efficient technologies normally occur in new construction. The second most cost effective installation is likely for retrofit situations when there are plans to either repair or upgrade an existing system or equipment. However, it is certainly possible that high cooling, heating and/or electricity costs, or financial incentives could make the proposed case financially attractive, even in retrofit situations that do not meet the above criteria.
While preparing the cost analysis for the proposed case, it is important to consider that some items should be "credited" for material and labour costs that would have been spent on a "conventional" or base case system had the proposed case system not been considered. The user determines which initial cost items that should be credited. It is possible that engineering and design and other development costs could also be credited as some of the time required for these items would have to be incurred for the base case. A "User-defined" input cell is provided to allow project decision-makers to keep track of these items when preparing the project cost analysis. These "credits" can have a significant impact on the financial viability of the proposed case.
1A reminder to the user that the typical values for cost items mentioned in the manual are for a 2006 baseline year in Canadian dollars. Some of this data may be time sensitive so the user should verify current values where appropriate. (The approximate exchange rate from Canadian dollars to United States dollars was 1 CAD = 0.86 USD and to the Euro was 1 CAD = 0.72 EUR as of January 01, 2006).
