Project Description

  • DESIGN YEAR : 2014
  • CLIENT: MIDI srl
    Upgrading energy project Electrician
  • TOTAL SURFACE : ca. 16,000 m2


The project involved upgrading the energy efficiency of UnipolSai parking in Via Stalingrado 42 / a by the replacement of the ordinary lighting. The intervention has been dimensioned according to the UNI EN 12464-1: 2011, considering the limit values ​​set for the traffic lanes (5.34.3) and for parking areas (5.34.3) internal public car parks.
The progress made in the light appeared to be very abundant in the center of driveways (about 140 lx average) but insufficient in the end parts of some lanes (about 40lx average). Given the need not to change the primary distribution and to minimize the changes of the final distribution, the project provided for the continuance of the total number of devices and the reallocation of the sun in the driveways. The lighting design has been optimized to obtain, with new lighting fixtures, a maintained illuminance equal to 75-90 lx in parking areas and 105-110 lx in the aisles. In car parks and stairwells the terminal and main distribution is expected unchanged. In the maneuvering lanes it was instead provided for the supply and installation of lighting equipment in a slightly different position, maintaining the power from busway existing light and replacing some sections of the cables to the lighting plug. The number of circuits and the related commands were unchanged. The ignition times were unchanged as follows: the covered floors, all lit from 6:30 to 9:30 and from 17:00 to 23:00 on weekdays; the coverage plan, all lit with twilight (11 hours daily averages); the basement floors, two circuits switched on from 9.30 to 17.00; the floors, a Circuto lit from 9.30 to 17.00; in stairwells, all lit from 6.30 to 23.00 and presence detector from 23.00 to 6.00. Existing fixtures were replaced with as many LED 30W (24W in some of the stairwells points) to the floors covered and LED 26W in coverage.
