SifisaLux – Viario
SifisaLux – Viario is more than just a software for calculating lighting installations: it is an adaptable tool that, using an Excel spreadsheet as input, automatically calculates thousands of installations, even optimising the luminaire model to achieve the required levels with minimum consumption.
With calculation routines that have been extensively tested for years, the outputs will be adapted to your needs and completely customised.
With various licensing levels, from a free version to one that can be customized to suit the needs of any user.
At its highest license level, this application is especially aimed at Engineering and Energy Consultancies dedicated to the evaluation of lighting levels in urban areas in order to propose the replacement of luminaires to improve lighting levels and/or reduce consumption.
With this tool you will drastically reduce the hours of calculation and simulation, and with it the costs of personnel dedicated to these tasks.
The system searches for the best luminaire to meet the lighting requirements set and with minimum consumption. Optionally, the compliance of pavements, glare, pavement/road ratio, etc. can also be checked. It is also possible to establish margins of error different from those established by the reference standard (REE, EN13201,…).
Consult us and we will assess your needs.

1 The Excel processing option allows you to calculate multiple projects, defined through an Excel table, obtaining, for each project, the optimal luminaire from among those assigned for verification, to meet the required lighting levels.
The algorithm attempts to meet the requirements of the chosen regulations for the selected lighting class, with minimal energy consumption. If a valid solution is not found, it will offer the one that is closest to the reference levels.
2 We can configure, upon request, any selection criteria for the optimal combination (lowest consumption, greatest uniformity, etc.). Custom developments will be assessed in advance.
