Organization Overview
Casas Church is a large and active community church located in Tucson, Arizona. With expansive facilities and year-round HVAC demands driven by the desert climate, energy efficiency plays a critical role in managing operational costs while maintaining a comfortable environment for congregants and staff.
Committed to responsible stewardship and long-term sustainability, Casas Church began exploring advanced solutions to reduce unnecessary energy waste and improve the performance of its electrical systems.
The Challenge
An analysis of the church’s HVAC chiller revealed significant inefficiencies:
- Current draw of 129 amps
- Power factor between 44% and 52%
- Excessive reactive power and wasted demand
- Higher-than-necessary utility and demand charges
- Increased electrical and mechanical stress on HVAC equipment
Despite consuming large amounts of electricity, only a fraction of that power was being converted into useful work. The remainder was lost due to poor power quality—driving up costs without improving performance.
The Solution
To address these inefficiencies, Casas Church deployed the PMCS Power Power Management Controls System on its HVAC chiller.
Unlike passive monitoring tools, the PMCS system actively optimized the electrical performance of the chiller by:
- Continuously correcting power factor
- Reducing reactive power (kVAr)
- Stabilizing electrical demand
- Improving overall power quality in real time
The installation and commissioning process was seamless and required no interruption to church operations—an essential requirement for a high-traffic community facility.
The Results
The impact was immediate and measurable.
After installation, Casas Church achieved:
- 50% reduction in energy demand
- Significantly improved power factor
- Lower monthly electricity and demand charges
- Reduced electrical and mechanical stress on HVAC components
- Improved system reliability and longevity
By eliminating wasted power rather than adding new infrastructure, the church was able to unlock savings using the energy it was already paying for.
Key Performance Metrics
| Metric | Before PMCS Power | After PMCS Power | Improvement |
|---|---|---|---|
| Current Draw | 129 Amps | Reduced & Optimized | Lower Demand |
| Power Factor | 44–52% | Significantly Improved | Higher Efficiency |
| Energy Demand | High | 50% Reduction | Major Cost Savings |
What the Customer Says
“The installation of the PMCS Power system significantly reduced energy demand while ensuring efficient operation of our HVAC system.”
Why This Matters
Casas Church’s success highlights a critical truth about energy efficiency:
You don’t always need more power—you need better power.
By improving how electricity is used rather than how much is produced, PMCS Power delivers immediate, verifiable savings without waiting years for infrastructure upgrades or regulatory changes.
This project now serves as a model for:
- Churches and community facilities
- Commercial buildings
- Schools and campuses
- Data centers and mission-critical HVAC environments
