Understanding Economizer Logic in Building Automation
During the occupied cycle, your building’s BAS (Building Automation System) ensures indoor comfort efficiently:
✅ Room sensors control:
🔥 Heating (via hot water coils or electric heaters)
❄️ Mechanical Cooling (like DX units or chillers)
🌬️ Economizer Cycle (leveraging outdoor air when favourable)
🌀 The system follows the ASHRAE Cycle II Economizer logic —
The fresh air damper modulates between minimum outdoor air and 100% outdoor air depending on temperature and energy-saving conditions.
💡 Why it matters:
This setup reduces energy consumption by using "free cooling" when possible, keeping indoor temps stable while optimizing operating costs.
📊 Buildings control = Comfort + Energy Savings + Sustainability
