As public and private entities collaborate to gain a better understanding of building assets through a variety of tools and services, a major obstacle presents itself across the board: the difficulty of joining various types of data from disparate sources in a single location. Typically, that effort is based solely on address matching strategies—an outdated strategy which often yields low match rates and leaves significant portions of the building stock unaccounted for across multiple data sources.
A unique identification system for buildings will provide a standardized framework under which a unifying field is used to match building data from various sources to a single object. It will facilitate data management and sharing by reducing the risk of mismatching or duplicating building data, and it will ease the burden of data exchange.
