Levels are not aspirational. They are technical thresholds. A project achieves the ILS level that matches its measured performance against the standard.
The home is fully visitable for any person, regardless of mobility or age. Primary social spaces function without barrier. Entry, main level, and at least one sanitary space meet the visitability threshold.
The home is fully habitable for occupants across the full life arc. Sleeping, sanitary, food preparation, and circulation systems all operate without structural retrofit. Spaces are pre-equipped for adaptation.
The project performs across the full standard and integrates cognitive accessibility, sensory environment, and technological readiness. Designed for long-term autonomy, multigenerational use, and full adaptability without intervention.
The level is a description of what the certified home can support, not a ranking of design quality. A Silver project is not a worse project than a Gold one. It is a project whose measured performance against the standard places it at the Silver threshold.
Levels also reflect intent. A studio apartment may be inherently constrained from reaching Platinum. A single-family villa with the same materials and finishes may reach it because the program supports the criteria. The level should be read against the project type and program.
Each certified project receives a technical report alongside the level. The report explains how the level was reached, where the project meets and exceeds criteria, and where it falls short of the next tier.
