Solution Focal Points

Energy Cost Transparency and Optimization

Operational Improvements Investment Opportunities

Utility bills are opaque and difficult to understand. The RTIS® utility rate engine provides transparency and reduces costs by analyzing your building’s usage profile to determine the most attractive distribution rate classes and supply rates, identifying billing errors and applicable tax credits, and tracking utility tariff changes.

Through real-time monitoring and analytics on your critical loads, RTIS®dissects your business processes and building system performance to identify process improvements that reduce costs and improve your company’s sustainability.

RTIS® tracks historical and real-time equipment performance and factors in weather conditions to detect performance anomalies and inefficiencies to identify attractive capital investment opportunities.

The RTIS® Energy Analytics Savings Timeline

Global Healthcare and Insurance Company

$400K Annual Savings

What We Identified:• Wasted energy usage during Idle, unoccupied periods• High building demand during ISO peaks, driving up capacity tag costs• Excess cooling expenses during certain Monday mornings• Timing and magnitude of intermittent periods of excess usage that are

driving up energy costs

Informed Strategies: • Shutdown of loads that were previously left on during unoccupied

periods• Utilize ISO 6-day forecast and RTIS® alerts to identify periods when ISO

peaks may occur in order to minimize their capacity tag and related costs• Pre-cool the building during off-peak weekend periods when the

forecasted outdoor temperature exceeds a certain threshold• Shutdown non-critical loads when RTIS® alerts informs management that

peak demand thresholds have been met

12% of Annual Energy Costs

High School in CT

What We Identified:• Wasted energy usage in intermittently occupied areas through sub-metering• Unnecessary periods of high energy usage in the early morning and late at night• Lack of visibility into the usage and cost contributions of different sections of the

building

Informed Strategies: • Deploy CO2 sensors and VFDs to modulate and curtail usage in auditorium and

other intermittently occupied areas• Monitor usage to identify anomalies and other areas of the building that are

operating inefficiently • Cycle RTUs and AHUs across multiple units and zones during hot summer days to

minimize coincident demand • Setup demand thresholds in RTIS® to automatically curtail non-critical loads during

high demand months• Create a schedule to eliminate non-critical loads during idle and unoccupied

periods

$50KAnnual Savings

20% of Annual Energy Costs

High Performance Plastics and Films ManufacturerWhat We Identified:

• Two large compressors were running simultaneously on several occasions over the comparison period, where management thought a system was in place to avoid this from happening

• One compressor was using ~100kW more than an equivalent unit during the same operating periods and conditions

Informed Strategies:

• Minimize usage of the less efficient compressor

• Evaluate all other compressors to create a prioritized usage approach

• Repair/replace inefficient compressor
