Acceptable Range of Facility Designs Group 1 Interiors

Too Elaborate

Ensure that daylighting and other features are life cycle cost effective. Avoid unnecessarily complex patterns and elaborate materials.

Acceptable Range

Develop open-plan configurations for office, administrative, operational and related activities and spaces that reflect Group 1. Use durable long-lasting finishes in core areas for walls, ceilings, floor coverings and built-in casework appropriate for Group 1.


The visual character and detailing of systems, materials and finishes in Group 1 facilities may be more refined than those in Groups 2, 3 and 4.
