by Alexander Maurer

“ECON-Calc” is the name of the newly released project economics & cost evaluation tool where high performance buildings, both new construction and retrofits, can be assessed in detail looking at their economical and ecological performance. This comprehensive tool developed by the Energieinsititut Vorarlberg is aimed at architects, energy consultants, engineers, municipalities and other professionals working in the Passive House and Low Energy Building field.

As a user you can evaluate the building(s) from three different perspectives depending on your project role:

  1. Buyer perspective: i.e. Purchase price, Incentives/Subsidies/ Lifecycle Costs, Economics, etc.
  2. Developer/Builder perspective: i.e. Financing Costs, Break Even Analysis, Sales Price, Life Expectancy, Life Cycle Costs, Maintenance Costs, etc.
  3. Owner perspective: i.e. Investment/Financing Costs, Life Expectancy, Maintenance Costs, Lifecycle Costs, Incentives/Subsidies, Project Economics, Design Optimization, etc.

Overall a very comprehensive tool giving you lots of data and info; it also collaborates well with PHPP, but its currently only available in German with some data based on regional numbers (Vorarlberg/Austria). So some adjustments for North American projects are necessary to use this tool efficiently – but it looks promising.

Marken Projects is using some features of the tool on a test basis on two projects – looking forward to post the results here in the near future.
