Eneractive Eye On How to Optimize Building Systems Through Fault Detection Diagnostics (FDD) By David Landman, Director of Engineering, New England
A building management system (BMS) or building automation system (BAS), is a computer-based control system typically installed in larger buildings that controls and monitors the building's mechanical and electrical equipment such as heating, air conditions, ventilation, lighting, power systems (meters), fire systems, and security systems. A BAS is designed to control the systems it monitors based on the algorithms programmed by the BAS vendor to provide occupant comfort, efficient operation of building systems, and reduction in energy consumption and operating costs. However, these systems can cover up faults in operations. No matter how much money is invested in a BAS and energy-efficient equipment, overall energy usage will not be minimized if the BAS is not property optimized and maintained. The key to optimizing a building automation system is with FDD, fault detection and diagnostics, and optimization.
Fault Detection, Diagnostics, and Optimization FDD platforms automate the process of detecting faults with physical systems and processes, and diagnoses their potential causes. FDD systems for HVAC generally use a database of fault rules that analyze BAS and meter data to determine fault conditions. While a BAS has alarms for temperature or failed equipment by a single point, FDD drives 4

to a much deeper level of analysis of a system and determines root cause faults.
Top 4 Optimization Faults: 1. Scheduling When a BAS is first commissioned, an operating schedule is programmed in for each piece of equipment or system; however, buildings have constantly changing schedules and temperature requests. A typical office or university will modify the schedule according to the requirements of the space. That request may be for only one day, however, it may continue to stay in that override condition without FDD. As a result, the AHU serving the space may be using significantly more energy than prior to that day, yet no one has found that fault because there are no alarms to monitor. It goes undetected. 2. Air Change per Hour (ACH) reduction in zones Environmental Health and Safety (EH&S) officers oversee providing a safe building environment. EH&S officers follow guidelines and standards provided in the industry. However, as the standards have changed and FDD has become available, the ACH rates in buildings have not been lowered as quickly. Reducing ACH rates by 25% provides a 25% savings in heating and cooling, and a reduction in fan energy as well. For each zone in a building that is receiving 1,000 CFM of 100% OA conditioned,
that results in savings of approximately $1,000/yr. 3. Economizers not operating correctly Today’s complex systems are designed with modulating amounts of outside air based on return and outside air conditions. Advanced systems also monitor CO2 levels. A properly designed and operated economizer can reduce both heating and cooling during hours when outside air conditions are appropriate. If an outside air damper is 100% open when the outside air is below 32F, there is potential for frozen coils and added costs for facility personnel. If the outside air damper is 100% open when the OA is above 90F, the cooling coil may be signaled at maximum cooling capacity but not be able to provide adequate cooling. This not only results in additional cooling energy wasted, but also comfort complaints. In the case of spaces that
require humidity control, this may result in damage to rare library books, ORs that are not usable, and validated pharmaceuticals that are forced to shut down processes. 4. Equipment PID loop cycling issue HVAC and process equipment may be constantly modulating to maintain setpoint conditions. However, how often is the loop cycling every fifteen minutes? How much of a deadband is programmed into the sequence of operation (SOO)? Equipment than isn’t programmed correctly can lead to premature failure, resulting in additional increases in equipment costs and failures at the worst times. FDD allows for analyzing control loops and identifying which ones need to be tuned before equipment fails.
Edison Energy’s FDD Solution Virtual Energy Management (VEM) VEM is Edison Energy’s Continuous Commissioning or FDD Process. VEM Monitoring provides a continuous source of time-series building data. VEM Analytics provides for discovery, interpretation and communication of meaningful patterns in the data. VEM brings together energy and BAS data to provide instant insights into faults and optimization opportunities. The figure to the right shows the sustainability results of implementing VEM over time. Energy consumption stabilizes and decreases beyond a new baseline through continuous optimization.
What’s next with BAS Optimization As the Internet of things (IOT) continues to grow and wireless sensors become more plentiful in buildings, FDD platforms will be able to do more with the data available. In addition, although most FDD platforms currently only identify faults and optimization opportunities, the next step in the evolution of FDD will be to actively optimize operations, going from identifying faults and optimization opportunity to machine logic that will automatically update software algorithms to selfcorrect and self-optimize on an ongoing basis. This, combined with renewables, battery technology and microgrids will drive buildings towards net zero. There will need to be more FDD in the near future to meet energy targets and persistence of energy savings. ©Edison Energy. All rights reserved.

Energy Procurement Short Term Energy Outlook* A Snapshot of Electricity, Natural Gas & Renewables ELECTRICIT Y Electricity Consumption. EIA expects annual retail sales of electricity to the residential sector in 2018 to be 2.9% higher than sales in 2017 primarily as a result of increased electricity consumption in the first quarter of 2018. Forecast annual electricity sales to the commercial sector are up 0.6% this year from the 2017 level. Industrial sector electricity sales are expected to grow by 0.4% in 2018. Forecast total U.S. consumption of electricity grows by 1.3% in 2018 and by 0.5% in 2019.
NATURAL GAS Total U.S. natural gas consumption averaged 74.0 billion cubic feet per day (Bcf/d) in 2017, a 1% decrease from 2016. Natural gas consumption is forecast to increase by 3.5 Bcf/d in 2018 and by 2.2 Bcf/d in 2019. The 2017 decrease in total natural gas consumption mainly reflects warm winter temperatures and lower electric power sector use. In 2017, U.S. heating degree days (HDD) were 2% lower than in 2016, and U.S. cooling degree days (CDD) in 2017 were 8% lower than in 2016. Electric power sector use of natural gas decreased by 1.6 Bcf/d (6%) in 2017. The decline reflects competition from increasing renewable energy use (particularly hydropower), competitive coal prices, and overall lower electricity generation levels.

The Solution | Quarterly | January 2018
RENEWABLES After increasing by 13% in 2017, EIA expects total generation from renewables in all sectors (including utility- and small-scale generators) to decrease by 3% in 2018 and then to increase by 7% in 2019. Forecast electricity generation from hydropower decreases by 12% in 2018 and increases by 2% in 2019. This change in hydropower generation drives the decrease in overall renewable generation growth in 2018. Generation from renewable energy other than hydropower in the electric power sector is forecast to grow by 3% in 2018 and by 9% in 2019. EIA estimates that energy-related emissions of carbon dioxide decreased by 1.0% in 2017 and forecasts these levels to increase by 1.7% in 2018 and by 0.2% in 2019. These forecasts are sensitive to assumptions about weather, economic growth, and fuel prices.
