What is the term used for the selective installation of sprinklers in historic buildings?

The term for the selective installation of sprinklers in historic buildings is indeed the selective placement of sprinklers. This practice acknowledges the unique architectural and historical features of these structures while still addressing fire safety needs.

When retrofitting historic buildings with sprinklers, fire protection engineers carefully evaluate where the sprinklers should be installed to minimize alterations to the building's original character. This approach allows for fire suppression systems to be effectively integrated without compromising the building's historical integrity or aesthetic appeal. The focus is on strategically placing the sprinklers in areas where they are most needed for safety while avoiding significant changes to the building's appearance, which is crucial in preservation efforts.

The other terms listed do not accurately capture this specific practice of sprinkler installation in historic settings. They either represent concepts not widely recognized in fire safety or do not refer specifically to the selective and careful reasoning applied in the context of historic preservation.
