An expert may use building material data other than that in the LuxEeB-H software, namely:
- Ökobau.dat 2016 in accordance with standard EN 15804 (edition of 18.05.2016)
- or the manufacturer's EPD (Environmental Product Declaration) in accordance with standard EN 15804
Should it prove advantageous to use an EPD for a specific product, experts can use the Icalc calculator provided by the Ministry of Sustainable Development and Infrastructure, which can be downloaded from www.Klima-Agence.lu.
In the case of individual calculations made by the expert, the values required for calculation of the environmental indicators must be filled in on sheet no. 4 of the Icalc calculator.
Then the environmental indicators of the specific product must be manually transcribed into the U-value calculation sheet in the LuxEeb-H software.
General reminder: Any constituent layer (insulation, membranes, wood, blocks, panels) may optionally be calculated using this method. However, using an EPD for a specific product is not the primary method to be used by experts. In order to make the calculation of environmental indicators as simple as possible, a database is available in the Lux-Eeb-H software and all the values entered therein can be used for the calculation of environmental indicators.
