Tool for economical assessment of life cycle cost in PEBs

In this task an excel-based tool is developed to assess life cycle economic impact taking 
into account direct costs as well as indirect costs and it allows to evaluate 
finance/funding schemes in the time horizon of 30 years. One challenge on the Cultural-
E project is to show solution sets that make the extra costs for PEB compared to nZEB 
repayable within 8 years. The current nZEB standard is therefore the reference case and 
the tool is designed to compare up to 5 variants. This allows 4 solution sets to be 
compared with each other and with the reference nZEB.
