LuxEeB-H-tool

The Grand-Ducal regulation on energy performance indicates in the appendix that energy performance calculations and certificates must be affixed with an expert's registration number. The numbering system is explained in point 3.2 of the explanatory notice for the amended Grand-Ducal regulation of 30 November 2007 on the energy performance of residential buildings under the section "Notes et informations".

Each application "LuxEeB-H-tool" is personalised for a given expert and contains, in its licence number, a unique non-editable personal expert registration number which is indicated automatically on every calculation and certificate generated by the application. Each expert can therefore only do calculations and establish certificates in his own application with his personal registration number.

The aforementioned system implies that each expert must request a user licence for the LuxEeB-H-tool in order to print out energy performance calculations and certificates with his personal expert registration number.

The establishment of official energy performance calculations and certificates requires the use of the LuxEeB-H-tool in a version which is higher than version 2.81.

The installation of a new version of the LuxEeB-H-tool is very easy and only takes a few minutes for those who already have a user licence. The update does not require a new user licence.
