How Crime Prevention Through Environmental Design (CPTED) Principles Shape DesignIn the past year, we have seen civil disturbances, widespread retail looting, and attacks on government buildings. These events result in property damage, and sometimes even injuries or deaths.  So, what can be done to prevent or mitigate these events at your facility? Telgian Engineering & Consulting, LLC (TEC) Vice President, Security Risk Consulting Lauris Freidenfelds recently explored essential CPTED principles in the just-published article, “How Crime Prevention Through Environmental Design (CPTED) Principles Shape Design” for Buildings magazine.

“It starts with a risk assessment,” Freidenfelds explains. “What are the risks to your facility or building from outside influences? What kinds of attacks are possible and probable? What is the impact and what can be done to mitigate that? Security measures will be different for government, iconic buildings and retail or office buildings. What is your specific risk?”

In the piece, Freidenfelds also reviews the three key principles of CPTED: Natural Access Control, Natural Video Surveillance and Territorial Reinforcement.  

Natural Access Control is the ability to control access to a space and delineate the space as public or private. It also looks at the movement of people and placement of people within a space. The implementation of this can be done through the employment of doors, landscaping, lighting, fencing and gate entries. 

Natural Surveillance emphasizes the opportunity to maximize visibility of a space and identify those who would be considered as a normal user versus an abnormal user. Typically, this is achieved through the use of windows, strategized lighting and planned landscaping to create an open environment. 

Territorial Reinforcement influences a space or environment and creates a sense of ownership of that space for normal users, while further deterring and defending against the abnormal users or potential criminals of that space.
