Load Management Program

Data chart showing a public building’s energy use reduction before and after the application of a load management program.

Program Overview

DCAS launched the Load Management (LM) Program in 2016 to work with City buildings to find no/low cost operational energy saving solutions to help meet our 80 by 50 goals. LM provides real-time data visualization tools, data analysis, and hands-on training to building operators. Common LM measures include adjusting heating and cooling setpoints, scheduling HVAC equipment, optimizing VFD control loops, and addressing simultaneous heating and cooling. The program’s success thus far is rooted in fostering a culture where building operators use the visualization of energy usage to find energy-savings opportunities.  The Load Management Program has helped reduce emissions, lower energy use, ensure investments actualize improvements, and reduce energy costs at no to minimal upfront cost. With near real-time meter (RTM) data now installed on more than half of the municipal load, the LM team is working with agencies and actively analyzing and prioritizing new locations for program participation.

Outcomes

In fiscal year 2019, the Load Management team was responsible for 67,321 MMBTUs in net energy savings! On average, this translates into 10% energy savings for all City buildings participating in the program. As a result of these savings, approximately 3,700 metric tons of CO2eq have been avoided, and $1 million of tax payers’ dollars have been saved. To put this into context, the savings is equivalent to taking approximately 800 cars off of the road or eliminating 11 round trip flights from NY JFK to London Heathrow.         

How to Participate

While the Load Management team is willing to engage any municipal building with a savings opportunity, we focus on buildings with the following characteristics:

  • large energy loads (typically, 300KW and above) with high energy use intensity.
  • real-time metering infrastructure with communication capability.
  • building equipment and systems that generally are in good working order.
  • interested and committed facility personnel.

If you think your building meets all or some of these criteria, or if you have any questions about our work, please reach out to the Load Management Associate Engineer, Elizabeth Taveras
