Industry: Defense Contractor - Manufacturing and Conditioned Space
Total Number of Sites: 150 Sites Worldwide
Sites Currently Using EnerNOC: 10 sites across Long Island, New York and Southern New Hampshire
This defense contractor manufactures some of the most sophisticated products in the world, from vehicles to body armor to computer systems. Its operations are energy intensive and highly sensitive. Plant temperatures need to be constantly controlled, for both employees on the floor and some of its products. The Company is serious about energy management activities as a tool for driving savings, but it must not impact the quality of production processes or outputs.
The Customer realized that there were significant opportunities to identify savings by tracking and analyzing real-time data, but as a defense contractor, it was limited in the amount of information it could share with a third-party vendor. To give staff members greater control over energy consumption at their facilities, the customer installed an advanced building management system (BMS). Even with additional control, they recognized that savings opportunities were passing them by. They needed a tool that would integrate real-time energy data with information about their tariffs to give them actionable insights.
Adding to the Company’s challenges, it maintains a large facilities team that is segregated by site and specialty. The sustainability managers are not always able to work in lockstep with the building techs, making quick operational fixes harder to execute.
The Company coordinated closely with EnerNOC to ensure a workable solution that would give its facilities teams visibility into their data through energy intelligence software (EIS) without creating any security concerns. EnerNOC installed a device behind the Company’s firewall that streams data from the Company’s BMS to EnerNOC’s cloud-based energy intelligence software platform. By installing behind the Company’s firewall, the Company was able to regulate exactly what data EnerNOC had access to. At the same time, it gave both the Company and EnerNOC the analytical power needed to find energy savings opportunities. The data is reviewed regularly by EnerNOC’s professional services team, which meets on a regular basis with the Company’s full facilities and operational teams to discuss energy savings opportunities and priorities.
Optimizing Night Shutdown. Savings: $130k/yr
No matter how sophisticated a BMS, it still requires that someone program it correctly to optimize energy consumption, and even if that happens, on the ground actions can often cause settings to be over-ridden. These two factors often lead to unnecessary energy waste. Prior to deployment of EnerNOC’s software, many of the Company’s facilities were not setting back during unoccupied evening hours, costing the company thousands of dollars.
One of the standard reports generated by EnerNOC’s EIS is a Night Shutdown Analysis, which compares overnight energy consumption across each site. When the night shutdown report was run for the month of December 2013, it revealed two easy savings opportunities.
First, two facilities actually used more energy overnight than during occupied hours. The team was keeping the buildings at a consistent temperature set point, regardless of the fact that they were unoccupied, and as a result, it required more electricity to heat the building during the cold evening hours. By resetting the BMS to allow the internal temperatures to drift and then heating the building again in the morning before employees arrived, the Company could significantly reduce operating costs.
Second, the report gave the team a benchmark of how each facility was performing relative to the others in the portfolio. If each of the five buildings shutting back at a lower-than-average percentage could adjust its setback protocols to the average setback level (16% demand reduction), the Company could save over $130,000 a year.
Holiday and Weekend Setbacks. Savings: $10,000/yr
Because they often occur on weekdays or on different days each year, holidays are one of the most common causes of energy waste. Teams have to proactively make BMS adjustments to ensure lighting, HVAC, and other energy-hogging systems operate in “unoccupied” mode. With competing demands on time, even building managers highly familiar with their BMS can overlook elements of the setback. For this Company, a quick review of its energy profile highlighted that a number of buildings failed to shut down on holidays, which was costing $10,000 a year. In one case, a facility ran on Christmas Eve as if it was a regular workday. Further compounding the waste, the Company set its peak demand for the month on New Year’s Eve. The team took this experience to heart. On the advice of its designated EnerNOC advisor, the team conducted an “Unoccupied Audit” – a quick walk through over the July 4th holiday, during which the team documented which systems and processes could be adjusted to reduce energy consumption.
The same wasteful activity occurring over the July 4th holiday was present on the average weekend as well. The unoccupied audit revealed that lights, HVAC systems, and TV’s displaying digital signage didn’t shut off during non-working hours. The EnerNOC advisor is now working with the Company’s local utilities to secure rebates to fund the installation of timers for equipment like the digital monitors.
Beyond the financial implications of better energy management, the biggest benefit this Company sees from its engagement with EnerNOC is the ability to align a diverse set of stakeholders. Sustainability managers, facility managers, energy engineers, BMS technicians, and HVAC technicians from all 10 facilities join the regular check-ins, which are facilitated by a designated EnerNOC energy advisor. As a team, they walk through the savings opportunities surfaced through the software and discuss upcoming priorities and projects.
