Our Project Focus

The focus of our project is to begin the standardization process between different faculty buildings, starting with occupancy sensors for air conditioning.

Simple occupancy sensor systems automatically turn off the air conditioning when no movement is detected for a set period of time, ensuring energy is only consumed when spaces are actively in use.

Occupancy Sensors: The Foundation of Efficiency

Immediate Energy Savings

Occupancy sensors provide instant energy savings by eliminating wasteful cooling of unoccupied spaces. Studies show reductions of up to 30% in energy consumption.

🎯

Precision Detection

Advanced occupancy detection technology accurately identifies occupancy, ensuring comfort is maintained while eliminating unnecessary operation.

💰

Cost Effective

Occupancy sensors offer one of the highest returns on investment in energy efficiency, paying for themselves through reduced utility bills.

🌱

Environmental Impact

By reducing energy consumption, occupancy sensors significantly lower carbon footprint and contribute to sustainable building operations.

🔧

Easy Integration

Occupancy sensor systems integrate seamlessly with existing air conditioning infrastructure, requiring minimal installation and maintenance.

📊

Data-Driven Insights

Occupancy sensors provide valuable occupancy data, enabling better space utilization planning and further optimization opportunities.

Corroborating Data

Multiple independent studies confirm that occupancy and motion-based control of air conditioning can deliver substantial energy and cost savings, while preserving comfort and air quality.

Below is a snapshot of quantified savings from real buildings and simulations using occupancy-centric controls and occupancy sensor systems.

Single-Family Home (Texas, USA)

17.6% seasonal HVAC energy savings in the 2023 cooling season, with daily savings up to ~35% using occupancy-centric controls.

Long-term field testing of occupancy presence sensors showed significant reductions in cooling energy use without compromising comfort.
