Answer:
SURVEILLANCE-SPECIFIC DESIGN.
Explanation:
Defensible space offers a series of architectural guidelines that can be used in the design of new urban residential complexes to promote both the residential group’s territorial claim to its surroundings and its ability to conduct natural surveillance. The designs are: site interrelationship design, site design, street design and surveillance-specific design.
Surveillance-specific design can be used to increase general visibility by providing adequate lighting, by reducing or eliminating physical barriers to visibility, and by the visibility-promoting location of key areas (entrances, lobbies, elevator waiting areas, parking areas e.t.c.) so as to be directly visible from as many viewpoints as possible.
Since the data center designer requested additional lighting for the entrance to the data center as well as the removal of a object which is blocking security's view of the entrance, then it is an example of SURVEILLANCE-SPECIFIC DESIGN.
