Buildings shape behavior, health, performance, and risk—yet most are still managed blindly. EQi360 introduces a new intelligence framework for understanding how indoor environments truly affect the people who occupy them. Moving beyond static certifications, periodic audits, and compliance checklists, this book defines Experiential Quality Intelligence (EQi) as a measurable, operational discipline—one that enables owners and operators to assess, optimize, and govern environmental performance in real time. At the core of EQi360 is a breakthrough concept: Environmental Aerobic Capacity™ (EAC) . EAC quantifies a space’s ability to sustain healthy air, thermal stability, biological safety, and cognitive performance under real occupancy and usage conditions—without crossing environmental risk thresholds. It reframes indoor quality as a capacity problem , not a design intent or one-time certification. Drawing from building science, systems engineering, environmental health, and applied AI, EQi360 establishes a unified model across four critical domains: Air Quality Risks - Environmental Biorisks - Climate & Comfort Risks - Physical Security Risks Rather than treating these factors in isolation, EQi360 demonstrates how they interact—and how modern sensor networks, building systems, and analytics can be orchestrated into a continuous intelligence layer. This book is written for professionals responsible for environments where performance, safety, and experience matter: Hospitality and resort operators - Facilities, engineering, and real estate leadership - Architects, designers, and workplace experience teams - Healthcare and institutional operators - Public-sector and infrastructure decision-makers Inside, readers will learn how to: Move beyond legacy standards toward measured experiential performance - Translate environmental data into executive-level decision signals - Reduce operational risk while improving occupant experience - Prepare assets for emerging EQi-based ratings and certification models EQi360 does not argue that environments should be better. It shows how they can be measured, managed, and continuously optimized —with the same rigor applied to energy, safety, and financial performance. As expectations rise across hospitality, government, healthcare, and commercial real estate, experiential quality is becoming a governed asset . EQi360 provides the framework to lead that transition.
