How material choices, design strategies, and construction practices affect occupant health, comfort, and sustainability.
What Is Indoor Environmental Quality (IEQ)?
IEQ refers to the combined environmental factors—such as air quality, thermal comfort, lighting, acoustics, and ergonomics—that influence occupant health and well‑being :contentReference[oaicite:0]{index=0}.
How Interior Construction Influences IEQ
- Material Selection: Choosing low-VOC paints, adhesives, and interior finishes helps minimize pollutant emissions and improve air quality :contentReference[oaicite:1]{index=1}.
- Thermal Comfort: Incorporating insulation, adaptive HVAC practices, and passive cooling strategies enhance thermal satisfaction—tools validated by MI NBC‑2016 guidelines and adaptive comfort models :contentReference[oaicite:2]{index=2}.
- Daylight & Lighting Design: Natural lighting and balanced artificial lighting improve comfort, reduce energy usage, and contribute to occupant satisfaction :contentReference[oaicite:3]{index=3}.
- Acoustics & Ergonomics: Thoughtful partitioning, sound-absorbing materials, and ergonomic spatial design support focus, productivity, and occupant well-being :contentReference[oaicite:4]{index=4}.
Regional and Standard Guidelines
- Kerala Energy Conservation & Sustainable Building Code (ECSBC) 2025: Now includes indoor environmental quality within its criteria covering envelopes, lighting, HVAC, and comfort systems for commercial buildings :contentReference[oaicite:5]{index=5}.
- Eco‑Niwas Samhita (ENS): India’s residential building code promoting ventilation, sustainable systems, and enhanced IEQ in new homes :contentReference[oaicite:6]{index=6}.
- Study on Earthen Buildings in Kerala: Research in Calicut found that traditional mud constructions uphold superior thermal comfort and daylighting, highlighting the value of vernacular methods for IEQ :contentReference[oaicite:7]{index=7}.
Best Practices for Construction with IEQ in Mind
- Engage IEQ considerations early—during pre-planning—to identify pollutant sources and design control methods :contentReference[oaicite:8]{index=8}.
- Implement pollutant control strategies and maintain communication with occupants to minimize disruption and exposure :contentReference[oaicite:9]{index=9}.
- Carry out post-construction IEQ assessments to validate occupant comfort and compliance before re-occupancy :contentReference[oaicite:10]{index=10}.
