The 9 Foundations are the core elements of healthy indoor environments, distilled into clear and actionable guidance, and designed to bridge the gap between scientific research and you — the people who control, manage and occupy buildings.

Healthy Buildings Benchmark Dashboard

Every business tracks key performance indicators. But very few track what we call Health Performance Indicators, or HPIs. At a fundamental level, health drives human performance. This means that building performance is a critical metric that every business should be tracking.

Our building benchmark dashboard provides a science-based health assessment of your building portfolio and allows our clients to view recommendations and decide where to direct resources to have the greatest impact on health.
