Regulations
Business Context
Smart buildings can use occupancy, location, environmental, access, and behavioral data to personalize comfort, services, space allocation, and building operations. Greater personalization, however, may require increasingly detailed information about occupants, creating privacy and data-governance concerns.
Real Estate & Construction TRIZ Resolution
Personalization should use the minimum information required for the intended function. Anonymous occupancy signals, local processing, aggregated data, voluntary user profiles, limited retention, and purpose-specific permissions can provide responsive services without unnecessary collection of identifiable information.
Applicable TRIZ Principles
Principle 2 – Taking Out removes personal information that is unnecessary for the required building function.
Principle 3 – Local Quality applies different data requirements according to the specific service.
Principle 1 – Segmentation separates identifiable user information from operational building data.
Expected Outcome
More responsive building services
Stronger occupant privacy
Reduced unnecessary data collection
Improved data governance
Decision Indicators
Early indicators include:
Building systems collect personal information without a defined operational need.
Anonymous occupancy data could perform functions currently using identifiable data.
Information gathered for one service is routinely reused for unrelated purposes.
Personalization initiatives expand faster than privacy controls.
Occupants cannot clearly understand how building data is being used.
