3 Electrical installation
characteristics
These are the main installation characteristics enabling the defining of the
fundamentals and details of the electrical distribution architecture. For each of these
characteristics, we supply a definition and the different categories or possible values.
3.1 Activity
Definition:
Main economic activity carried out on the site.
Indicative list of sectors considered for industrial buildings:
b Manufacturing
b Food & Beverage
b Logistics
Indicative list of sectors considered for tertiary buildings:
b Offices buildings
b Hypermarkets
b Shopping malls
3.2 Site topology
Definition:
Architectural characteristic of the building(s), taking account of the number of
buildings, number of floors, and of the surface area of each floor.
Different categories:
b Single storey building,
b Multi-storey building,
b Multi-building site,
b High-rise building.
3.3 Layout latitude
Definition:
Characteristic taking account of constraints in terms of the layout of the electrical
equipment in the building:
b aesthetics,
b accessibility,
b presence of dedicated locations,
b use of technical corridors (per floor),
b use of technical ducts (vertical).
Different categories:
b Low: the position of the electrical equipment is virtually imposed
b Medium: the position of the electrical equipment is partially imposed, to the
detriment of the criteria to be satisfied
b High: no constraints. The position of the electrical equipment can be defined to
best satisfy the criteria.
