Security vs. Sustainability in Building Construction
Any facility executive involved in the design of a new building would agree that security is one important goal for the new facility. These days, facility executives are likely to say that green design is another priority. Unfortunately, these two goals are often in conflict. Consider the issues that arise when even a parking lot is being designed. From a security perspective, bright lights in the parking lot enable security cameras to pick up all activity at night. From a green point of view, a brightly lit parking lot is a waste of energy and a source of light pollution. An advocate of green design would argue for plenty of leafy trees and bushes in the parking lot to minimize the urban heat island effect; a security consultant would reply that trees in the lot will block surveillance cameras and provide hiding places for would-be criminals.
There is no shortage of conflicts between sustainability and security goals. Fortunately these conflicts can be resolved to the mutual benefit of both parties, resulting in sustainable and secure buildings and campuses. This balance can be best achieved if security is involved early in the design process.

The “early in the design process” bit is key here. I have read several books and articles on physical security that argue for “smart” lighting and surveillance.
For the parking lot and perimeter, lighting that comes on when someone trips the motion detectors is supposed to be more effective than all-night floodlights, since it also alerts the patrons and security guards that someone is moving about.
If you want to use natural light and create more open space into a building, that can be capitalized on as well.
For instance, large windows or openings can let the security kiosk have a good view into the parking garage stairwell. Someone can be seen prowling about or a shout for help is more likely to be heard.
