ENERActive Eye On Big Data & BMS
• Simplest and quickest program to graph small sets of data • Can create Macros (programming scripts), using Visual Basic language, to automatically filter & analyze data into graphs • Useful for data sets with predetermined columns such as BMS trending reports
• Executing Visual Basic Macros with large data sets an be extremely slow • Displaying multiple graphs with large data points will slow down the program • Limited selections and customizable nature of graphs
How to Make Sense of it all... With the increasing sophistication and capability for building management systems and energy modeling programs to measure, monitor, and record set points and HVAC operations for hourly or minute intervals, facility managers are quickly becoming overwhelmed with data and information. However, engineers should take full advantage of this wealth of information, as it provides an unprecedented understanding of how a building operates which engineers in the past did not have access to due to limited capabilities of BMS. There are many situations where large amounts of data, either hourly or minute intervals, are recorded to understand the operation of a building.
Three most common projects in which graphing large data is a necessity are:
Measurement and Verification
Hourly sub-metering of specific equipment are necessary to verify
energy savings of implemented projects. If the energy savings do not meet the proposed levels, an analysis of the hourly operation may determine incorrect equipment operation or programmed set points.
Calibration and Troubleshooting of Energy Models
With current energy model programs like eQuest, engineers have the capability to create hourly trending reports for various building set points or operations inputted into the model. This capability is especially useful to diagnose and troubleshoot an energy model when calibrating an energy model with building utility data or modeling proposed energy conservation measures.
Retro commissioning Projects
Certain RCx projects require monitoring and trending of existing building equipment to understand their operation. For example, HOBO loggers can be used to record fan speed, and HW/CHW valve positions of fan coils to determine proper outdoor air reset operation.
While filtering this big data on a spreadsheet-based platform is the most common method for analysis, graphing the data is a quicker and more effective method for understanding, reviewing, and analyzing. With the increasing amount of information collected and stored by BMS systems, engineers need to keep up with this pace and learn new programs to understand and make sense of this data. Being able to graph and visualize the data is an important step to understanding how a building is operating and can further help building engineers in various projects.

Eye On Graphing
R - GRAPHING & DATA ANALYSIS PROGRAM PROS
Table 1 - Visually shows mixed air temperature fluctuating between 20 F to 50 F. This indicates either a faulty mixed air temp setpoint or faulty operation of mixed air dampers, which is an opportunity for energy savings.
Table 2 - Shown above, 45 of 4681 unfiltered data points
Table 1 illustrates the ease in visually spotting patterns or anomalies on plotted graphs, as opposed to a spreadsheet of numbers, as demonstrated in Table 2.
Pictured left, Table 4 shows (with advanced capabilities) the option to plot a third variable or data series as a color gradient or varying point size.
• Free open source program with online community and tutorials • Archive of downloadable codes to create graph templates and analyze data • More customizable graph options compared to excel • Faster processing of large data compared to Excel
• Must learn R language, which is not a standard programming language • No customer support system since it is a free program
The ability to view and compare three different variables on one graph, such as outdoor air temperature, room temperature, and occupied/unoccupied mode, can provide a deeper and more efficient analysis compared to the limited graph options from excel. The Solution | Quarterly | April | 2

Back in the Day Volume 2 Our marketing manager approached me and asked if I would like to take a crack at another edition of “Back in the Day”, which debuted in the 4th Eneractive Newsletter. Initially, I was having some trouble in developing a theme – but by sheer luck, I was listening to some music a few nights ago, when a certain record that I was spinning (yes, I still use turntables) stuck in my mind. The song I was listening to was a Doo Wop classic from 1956, recorded by a Los Angeles group called The Six Teens. The title of the song is “A Casual Look” (check out the 45 and 78 rpm label scans from my personal collection). Almost instantly, I realized that I had my theme… “casual”. Today for the most part we all enjoy a casual atmosphere in the offices where we work. The term “business casual” has become the norm in many, if not most cases. Except for occasions when we may meet with clients, or participate in presentations/seminars, etc. we are not required to wear suits/dress shirts/ties. That wasn’t always the case. When I was starting out in the engineering profession, dress shirt and tie was an absolute necessity, even if our day to day activities did not include dealing face to face with clients. Most places actually did not have a documented dress code – simply because it wasn’t needed. It was understood that you WILL wear a dress shirt and tie in the office at ALL times…no exceptions. The concept of “Dress Down Friday” or something similar was decades away from being on the radar screen. During the so-called energy crisis of the mid 70’s, federal energy guidelines mandated that public office buildings maintain air conditioning set points at a few degrees higher than in previous summers. To no one’s surprise, our management was only too eager to comply - they suggested that we all drink more liquids and wear light colored clothing to help cope with the higher temperatures in the office. Management was approached with the suggestion that perhaps we could work in the office without wearing ties. No chance!!! Some 60 – 65 years ago, my Dad worked as a senior designer/draftsman in an office located on Vesey Street…ironically, only a short walk from our New York Office at 150 Broadway. Of course this was back in the days of the old drafting tables (not in their wildest dreams could anyone have even imagined anything like CADD). Picture wearing a shirt and tie on a 98° afternoon with sweltering humidity, with only a few fans in the room to slightly move stagnant air around. For the draftsmen, keeping the drawings on their boards dry and free of sweat was a major accomplishment. I’m may be dating myself again, but did anyone ever have the “privilege” of working with an old Leroy Lettering Set? Working with that apparatus on a blistering summer day was a real joy! Today we don’t think anything of yelling out to co-workers in the office, “I’m going downstairs for a soda, or a coffee, etc…does anyone want anything?” In years past, there wasn’t any such thing. We had a designated “break time” that was strictly adhered to – 15 minutes in the afternoon to get a drink, or maybe take a walk around the parking lot to stretch and get some air on a nice day. Other than that, work. The term “business casual” has become the norm in many, if not most we were expected to be at our desks or cubicles, with the only exceptions being a trip to the water cooler or to the restrooms. It’s only basic human nature to sometimes think that we have it rough these days, and to air out our gripes from time to time. But every now and then it doesn’t hurt to take a look back at what the previous generation had to deal with – it can really put in all in perspective. “Casual” has come a long way in the working environment!

Ask the Expert
Is it possible to incorporate present day, state of the art, data center energy efficiency features into existing data centers in order to achieve energy and cost savings, as well as reductions in emissions?
Issue: Energy Efficiency in the Data Center
The “clear” and concise answer to this question is YES and NO.
First, the bad news. It is much easier to incorporate energy efficiency best practices on a “clean sheet” in greenfield data centers as compared with older data centers. The potential for disruption and associated cost is very high in the implementation of certain measures in existing data centers that may impact the basic configuration and architecture of the IT equipment. For instance, implementation of optimal hot/cold aisle depends on integrating IT rack design with the HVAC equipment, which is very difficult and disruptive to implement after the fact. A very careful risk assessment needs to be conducted on any measure. The good news, however, is that depending on each site’s configuration, there will typically be several measures that can be fairly easily implemented. We have found that it is typically possible to improve the site’s PUE (power utilization effectiveness) to in the range of 1.4 to 1.7. PUE is in basic terms the ratio of total data center energy efficiency to the power drawn by the IT equipment, so a lower PUE is better. Although this is worse than can be expected in an optimal new design, it is often times about half the way there as compared with the existing data center operation.
What are some of the typical opportunities in existing data centers?
Electrical Consumption in America’s composite Data Center stock is in the range of 2% of the total electrical consumption in the country (according to the EPA), and is rising rapidly as the IT and mobile computing industries continue to expand. It is not unusual to see the power density in a company’s data center to be over 25 times as great in the data center, as compared with their offices. Great strides have been made in data center energy efficiency over the last ten years, based on a focus and collaboration from several key organizations, the major of which includes: • •
It is critical to carefully evaluate all measures for potential adverse impact to the data center, and particular measures are highly site specific.
Here are some of the measures that we have successfully identified and implemented in the sites that we have worked with:
• • • • • •
Implement a type of economizer (free-cooling) if it does not exist Optimize existing economizer operation Air-flow management (in all its various forms) Controls upgrades to optimally manage redundancy and diversity, and control set points UPS efficiency upgrades Lighting efficiency upgrades and lighting controls (often overlooked)
