Air, Water, and Comfort – Environmental Monitoring with IoT

While energy is often the centerpiece of ESG efforts, indoor environmental quality is just as critical, especially in smart offices designed for productivity and well-being. At Hoyo Tech, we see environmental monitoring not as an optional layer but as a foundational element of a healthy, intelligent workspace.

In our Skopje and Struga offices, we’ve implemented a network of IoT sensors and automation rules to measure, maintain, and improve indoor environmental quality, with Genera AI acting as the decision-making brain behind it all.

🌬️ Monitoring What Matters – Air, Water, and Light

🏢 Air Quality (AQI, CO₂, VOCs, Humidity)

• Sensors Used: 
  ➡️ Aqara, BlueAir, Xiaomi
• Metrics Tracked:
  ➡️ CO₂ levels in ppm
  ➡️ VOCs (volatile organic compounds)
  ➡️ PM2.5 particle matter
  ➡️ Temperature and humidity by room
• Automation Logic:
  ➡️ If CO₂ > 900ppm → trigger ventilation (window actuator or HVAC + Alexa Announcement)
  ➡️ If PM2.5 > 10μg/m³ → send air purifier notification and start BlueAir Purifier
  ➡️ If humidity < 30% or > 70% → adjust HVAC and alert facilities

💡 Lighting & Lux Levels

• Sensors Used: 
  ➡️ Shelly Door Sensors + Lux, Zigbee lux sensors
• Metrics Tracked:
  ➡️ Natural vs. artificial light balance
  ➡️ Brightness per workstation
• Automation Logic:
  ➡️ Adjust LED light intensity based on sunlight penetration
  ➡️ Ensure minimum lux thresholds for working conditions (≥ 100 lux)
  ➡️ Reduce lighting levels in unused zones to save energy

💧 Water Monitoring (Smart Irrigation)

• In Struga, smart water probes and soil moisture sensors manage outdoor irrigation.
• Weather-based logic controls schedules:
  ➡️ If soil moisture > 60% or rain forecast is > 40% → delay watering cycle
  ➡️ If moisture < 30% → activate irrigation with real-time valve feedback

🧠 AI Meets Environment – Genera’s Role in Environmental Comfort

Genera takes raw data from dozens of sensors and applies contextual logic:

• Maps comfort zones by combining air, temperature, light, and motion data
• Detects anomalies (e.g., a cold meeting room, or stale air in enclosed offices)
• Prioritizes energy efficiency without compromising comfort
• Uses feedback loops — if an employee adjusts a setting manually, it learns and adapts

📈 Metrics We Track for ESG

Human Comfort as an ESG Metric

We believe wellbeing is measurable - and by using IoT to optimize for comfort, Hoyo Tech redefines ESG in the workplace. This isn’t just about saving energy. It’s about making people feel better in the spaces they work in.

And the results speak for themselves:

• In Skopje, complaints related to temperature or stale air dropped by 40% in the first quarter.
• In Struga, optimized lighting and fresh air cycles increased focus scores in user feedback surveys.
