ENHANCED ENERGY EFFICIENCY AND COST SAVINGS
Sustainability & Energy Management Simplified
Real-Time Monitoring and Alerts:
Findings from the Smart Energy Analytics Campaign, conducted by the Lawrence Berkeley National
Laboratory's Building Technology & Urban Systems Division, have highlighted the significant
efficiencies and cost savings achievable through building analytics. The campaign supported 104
organizations across over 6,500 buildings and more than half a billion square feet, documenting
substantial impacts, including median annual energy savings of 3% with Energy Information Systems
and up to 9% using Fault Detection & Diagnostics.
According to a report by the U.S. Department of Energy (DOE), users of an energy and sustainability
management platform reported median savings of 17 percent (or $56,000) for 28 individual sites and 8
percent (or $1.3 million) for 9 portfolios. The median five-year energy and sustainability management
software procurement cost for a portfolio was $150,000, or $1,800 per monitored point, or $0.06 per
square foot. In three out of four cases, the payback on the platform was two years or less.
Users can receive notifications in real time when the energy consumption of their buildings exceeds
certain thresholds or deviates from its expected behavior. Combined with artificial intelligence models
to help detect anomalies in consumption, an EMS is crucial for identifying the underutilized and low-
cost opportunities to save. This system can reveal simple adjustments such as scheduling, temperature
controls, and facility startup/shutdown procedures that offer immediate and low-cost benefits,
demonstrating that even minor changes can lead to significant improvements. For instance, real-time
data allows facility managers to adjust HVAC settings for maximum efficiency, potentially reducing
energy bills by up to 20-30%.
Peak Load Management and Demand Response
WatchWire by Tango helps manage electricity demand charges, which is crucial when energy prices are
volatile. Through effective participation in demand response programs, businesses can reduce their
energy usage during peak times, leading to significant cost savings.
