Summary

The purpose of this website is to determine the significance of the term profitable measures in connection with energy declarations. The site has been funded by Boverket (The National Board of Housing, Building and Planning) and has been created by Lars Abrahamsson Property Consultant . The examples have been formulated in consultation with Karin Adalberth, prime project AB.

The website is based on the perspective of a property owner.  It is therefore of the utmost importance that the parameters and assumptions that form the basis of the proposed profitability calculations have been discussed with, and approved by, the property owner. See also the checklist.

The first section features examples of how to classify different energy saving measures.

The second section highlights the importance of correctly defining the investment costs for an energy saving project.

The third section demonstrates how to assess savings potential of a building. Here it is emphasized that changes in other operational costs and maintenance costs must be considered together with the changes in energy costs.

The fourth section discusses the calculation parameters that govern the results of the profitability calculations. 

Section five describes the calculation models that are normally used for profitability evaluations: pay-off and different versions of the present value method.

The sixth section presents an integrated calculation model EDC that can be used to present all the measurable quantities mentioned in the previous sections.

Section seven uses eight examples to illustrate how to use EDC in practical applications.

The final section provides links to documents that are considered to be useful for making profitability calculations for energy saving measures.
