How Can AI Help in Optimising Indoor Environmental Quality?

🔍 Why Indoor Environmental Quality Matters in Architecture

Indoor Environmental Quality (IEQ) directly affects our health, comfort, productivity, and overall wellbeing. It encompasses air quality, thermal comfort, lighting, acoustics, and more. With people spending over 90% of their time indoors, architects and designers are under increasing pressure to create healthier and more responsive environments.

Artificial Intelligence (AI) is emerging as a powerful ally in this mission. By analysing environmental data, simulating building performance, and automating responses, AI helps architects optimise IEQ throughout the design, construction, and post-occupancy phases.

📚 Key Ways AI Supports Indoor Environmental Quality

1. Real-Time Environmental Monitoring

AI-powered building management systems (BMS) collect and analyse data from sensors embedded in the building to monitor:

• Temperature and humidity

• Air pollutants (e.g. CO₂, VOCs, PM2.5)

• Noise levels

• Lighting intensity and circadian rhythm alignment

Machine learning algorithms detect patterns, predict issues, and make proactive adjustments to maintain optimal indoor conditions.

🔍 Example: Smart HVAC systems powered by AI can learn occupant behaviours and adjust airflows or heating schedules to maintain comfort while reducing energy waste.

2. Performance Simulation During Design

AI tools allow architects to simulate how different design decisions will affect IEQ before construction begins.

These simulations can model:

• Daylight penetration and glare

• Airflow and natural ventilation

• Thermal zoning and comfort levels

• Acoustic dynamics between spaces

This empowers architects to test multiple scenarios and optimise layouts, materials, and systems for better indoor conditions.

🔍 Example: Using AI tools like Autodesk Forma or ClimateStudio, architects can simulate daylight availability across floorplans to ensure optimal workspace lighting without excessive solar gain.

3. Adaptive Lighting and Shading Systems

AI-controlled lighting systems can adjust based on natural daylight levels, time of day, and user preferences. They enhance visual comfort while reducing energy consumption.

• AI dimming controls maintain consistent lux levels

• Circadian lighting adjusts colour temperature throughout the day to support wellbeing

• Automated blinds respond to sun position, preventing glare and overheating

This ensures users experience optimal lighting conditions in any season or time of day.

4. Smart HVAC and Ventilation Control

AI can optimise HVAC operation by learning how indoor and outdoor conditions change throughout the day — and how different zones in a building respond to those changes.

Benefits include:

• Maintaining stable temperatures across rooms

• Improving indoor air quality by adjusting airflow or triggering filtration

• Reducing energy consumption by avoiding over-conditioning

🔍 Example: In hospitals and schools, AI has been used to maintain precise thermal conditions while ensuring ventilation meets strict health standards.

5. Occupant Feedback Integration

AI tools can integrate user feedback from apps, sensors, or surveys to learn what makes occupants feel comfortable or distracted. This feedback loop enables:

• Personalised climate zones

• Dynamic lighting controls based on preferences

• Adjustments in real time based on usage patterns

This makes buildings responsive, adaptive, and human-centred.

🔧 Real-World Examples of AI Improving IEQ

Edge Amsterdam (The Netherlands)

Often referred to as one of the smartest buildings in the world, Edge uses AI to monitor lighting, temperature, and occupancy. The building’s systems constantly adjust to maximise both energy performance and occupant comfort.

MIT Media Lab

MIT’s research facilities use AI-enhanced environmental controls to create personalised micro-climates within shared workspaces — allowing each occupant to set preferences for light, temperature, and airflow.

Microsoft Smart Buildings

Microsoft’s AI systems manage air quality and lighting across their campuses by processing real-time data from thousands of sensors — creating healthier indoor environments while cutting energy use.

🚧 Challenges in Using AI to Optimise IEQ

Data Accuracy and Sensor Quality

AI systems depend on accurate, real-time data. Inaccurate sensors or poor calibration can lead to faulty adjustments, negatively impacting comfort or energy efficiency.

Privacy and Occupant Consent

AI systems often monitor occupant movement, preferences, or habits. This raises ethical concerns about data privacy and the need for transparent user consent.

System Complexity

Smaller firms or buildings without dedicated IT teams may struggle to install, manage, and maintain AI-enhanced systems — especially if multiple platforms need to communicate seamlessly.

🔮 Future Trends in AI for Indoor Environmental Quality

Predictive Maintenance for Air and Comfort Systems

AI will increasingly be used to anticipate equipment failures or air quality degradation — allowing facility managers to act before users notice a problem.

Personalised Environmental Control Apps

Occupants will be able to control their own microclimates through AI-connected apps — giving them autonomy while helping the system learn more accurately.

Integration with Wellness Certifications

Expect AI-driven IEQ systems to become integral in achieving standards like WELL, LEED, and BREEAM — where real-time monitoring and performance proof are essential for certification.

AI is only as useful as the people guiding it. Architects must understand how IEQ data works, how to interpret simulation results, and how to integrate intelligent systems into their design decisions. With the right training, AI can help you create buildings that are healthier, smarter, and more sustainable.
