Questions Every IT Manager Should Ask About Thermal Management

Managing data centers to keep servers and their applications functioning properly is a core responsibility of every IT manager, as is keeping costs and energy usage to a minimum. CIOs and IT managers don’t have to be cooling experts, but they should know enough to make intelligent management-level decisions about the most cost effective way to manage energy usage in their data center.

Today’s robust servers allow data centers to operate at hotter temperatures. You don’t need to run iceboxes anymore, nor should you need to wear a sweater inside your data center. A smart approach can reduce the electricity bill for cooling by up to 50 percent at many data centers, with simple but smart adjustments or investments to the cooling system.

The following questions and best practices will help you identify the best thermal management strategy for your data center, with the end goal of slashing energy costs without reducing availability of critical infrastructure.

Turn Up the Thermostat

Are you hot when you walk through your data center? You probably should be a little. The old standard was 72 degrees for return air (the mixture of air returning from computers to the cooling unit) and relative humidity at 50 percent. Today, you can push return air temperatures as high as 95 degrees (best to do this in small increments to avoid unexpected humidity trouble and to ensure all the IT equipment is functioning properly). This can be done over a few days with little risk to applications and IT equipment. Enlist your facilities manager or vendor partners to assess how to do so safely. Remember, for every 1 degree Fahrenheit increase in temperature you will save 1.5-2.0 percent of your energy costs.

Raise chilled water temperatures. For many years, 45 degrees was the standard for water in the chiller. That’s changing. Operating chillers up to 55 degrees is possible today, reducing energy consumption by 20 percent. Every degree matters—each 1 degree increase in water temperature reduces chiller energy consumption by 2 percent. This can make a huge difference, since the chiller is the heart of cooling system and consumes approximately 75 percent of the system’s electricity. Be careful to work with your facilities manager, because raising chilled water set points can reduce cooling capacity in your data center cooling units which is fine if you have some excess capacity.

United States: FERC Annual Enforcement Report Underscores The Importance Of Effective Compliance Programs

Last week, the Federal Energy Regulatory Commission (FERC) released its annual report on enforcement. The report, prepared by FERC’s Office of Enforcement, provides FY2014 statistics on the investigative and enforcement activities conducted by its four divisions—Investigations, Audits and Accounting, Energy Market Oversight, and Analytics and Surveillance. The full report is available here.

In the report, FERC confirms that its investigation and enforcement priorities for FY2015 and the foreseeable future will continue to focus on matters involving (1) fraud and market manipulation, (2) serious violations of reliability standards, (3) anticompetitive conduct, and (4) conduct that threatens the transparency of regulated markets.

Specific statistics in the report include the following:

  • FERC opened 17 investigations in FY2014, over half of which involved market manipulation;
  • more than half of these 17 new investigations arose from referrals based on conduct observed by FERC surveillance staff or RTO/ISO Market Monitoring Units;
  • nine notices of alleged violations were issued by FERC in FY2014, five of which involved alleged market manipulation (two of which have settled); and
  • every settlement of an investigation in FY2014 included provisions requiring the subject to enhance compliance programs and report back to FERC on the results of those enhancements.

The report also discussed recent improvements to FERC’s surveillance capabilities, including FERC’s gaining access to data from the Consumer Futures Trading Commission (CFTC) Large Trader Report and FERC’s ongoing efforts to determine if market manipulation contributed to the historically high natural gas and electric prices that occurred during the 2014 “polar vortex” events.


Since 2007, FERC has issued annual enforcement reports that provide insight into FERC’s largely non-public investigation work. These annual reports provide summary statistics of FERC’s entire enforcement program, as well as descriptions of significant recent cases.

Interest in FERC’s investigation and enforcement program has increased since the passage of the Energy Policy Act of 2005 (EPAct 2005), which amended both the Federal Power Act and Natural Gas Act to enhance FERC’s authority to prohibit market manipulation and assess significant penalties where manipulation was determined to have occurred. FERC Chairman Cheryl LaFleur recently expressed a continuing commitment to investigation and enforcement activities, which are expected to receive a boost when FERC Commissioner Norman Bay, formerly the head of FERC’s Office of Enforcement, replaces LaFleur as chairman in April 2015.

The contours of FERC’s authority over market manipulation—as well as the types of activities that constitute fraud or manipulation—are still being defined. In 2013, the DC Circuit ruled that FERC lacks jurisdiction over manipulation of natural gas futures contracts, and that the CFTC instead has exclusive jurisdiction over the trading of derivatives. However, FERC recently signaled its intention to seek legislation to address this jurisdictional dispute and confirm FERC’s jurisdiction over these products. In addition, other investigative subjects currently are challenging FERC enforcement actions based on both due process issues and jurisdictional issues. For example, FERC’s jurisdiction over allegedly manipulative activity related to retail demand response programs appears to be questionable, given a 2014 DC Circuit decision that such programs are outside of FERC’s jurisdiction.

Zigbee Opens Umbrella 3.0 Spec

The Zigbee Alliance is consolidating its specifications spanning six application areas into Zigbee 3.0 at a time when competing standards based on Internet Protocol (IP) are expected to see rapid growth. The move aims to simplify the user’s job of finding compliant Zigbee products by requiring component vendors to pass a more rigorous certification process.

The Alliance expects to start certification testing for Zigbee 3.0 in the fall of 2015. Compliant products will need to support the standard’s application profiles in home and building automation, LED lighting, healthcare, retail, and smart energy.

Zigbee 3.0 does not include two Zigbee specs — Smart Energy 2, a profile based on IP; and RF4CE, a version of Zigbee geared for remote controls. It does cover all specs based on Zigbee Pro, the group’s overarching standard for how networks are formed and devices attach to them across different application areas.

“Underneath the covers we are accommodating these multiple applications in a single standard, so Zigbee thermostats, for example, can be used in either home or office buildings,” says Ryan Maley, director of strategic marketing for the Zigbee Alliance.

The upgrade is a natural consequence of advances in hardware, Maley says. “When Zigbee got started, everything was based on 8-bit MCUs and separate radios, but now devices are running on 32-bit cores in SoCs with many more capabilities.”

The Alliance has already sponsored about three plugfests to test out the feature-complete but still-evolving specification.

The move comes at a time when Zigbee is under threat. Market researchers expect a surge of competing IEEE 802.15.4 products using the emerging IP-based 6LoWPAN protocols will take a significant share of Zigbee’s market over the next few years.

Silver Spring Networks: Moving From Meters to Smart Grid SaaS Provider

Silver Spring Networks has been striving to define itself not just as a smart meter vendor — an increasingly tough business to be in — but as a provider of software and services to put the smart grid’s increasing number of devices to use. Last week, it won a contract to provide consumer engagement and efficiency software to Michigan utility Consumers Energy, an early example of how it might be making that transition.

First of all, Consumers Energy picked Silver Spring’s software suite over multiple competitors, including incumbent Opower, a big name in customer engagement and energy efficiency, which had worked with the utility in the pilot version of what the utility is now taking to all of its 2.7 million customers.

Second, it’s the first big contract that’s not built on Silver Spring’s own smart meter network. Instead, Silver Spring will deploy its software over Consumers’ cellular-enabled smart meters from Itron. That in itself isn’t so unusual — many smart meter deployments use different pieces of software from different vendors, both for core network and data management functions and for the consumer engagement portals and platforms they make available to their customers.

But Silver Spring is taking that integration role a step further by promising to put its SilverLink Sensor Network to use across the Itron cellular network. SilverLink is the technology platform Silver Spring launched earlier this year with the promise of fast and agile data management across networked smart grid devices, as well as to the cloud, and this is the company’s first foray into devices that aren’t using its own hardware.

EnergyHub CEO talks white-label frustrations

EnergyHub is a Gowanus-based company of about 25 that was acquired by Alarm.com in May 2013.

Quick recap: EnergyHub was early into the business of making programmable and internet-connected home thermostats, but when the big hardware makers came in, the company pivoted. It was ahead on software and quickly the larger manufacturers turned to EnergyHub to white-label consumer-facing software for their equipment.

The next phase for EnergyHub was demand response at the utility level. The company had software that would reach out to consumers’ devices and make small adjustments to thermostat settings in exchange for credits on energy bills. (Customers had to agree to join the program, but the benefits were strong.)

When we last spoke, the company was expanding its territory in Texas and California.

Seth Frader-Thompson, one of its founders and the company’s CEO, spoke to us about, among other things, the challenges of being a white label software business, the Polar Vortex and the internet of things.

(This interview has been edited for length and clarity.)


Tell me what you’re seeing right now as a company using software at the enterprise level to help people control energy consumption.

The most interesting thing that’s capturing a lot of people’s imagination now, is that every internet of things device probably was put there because the customer bought it for some specific reason. But the customer is not really extracting the full value of that.

Usually there’s someone out there somewhere who’s willing to do something. I think if you fast forward five years you’re going to see a million unforeseen benefits of all these internet-connected devices. But the best one right now is if you go buy a connected thermostat, in many markets the utility will actually pay you for the ability to control your thermostat. The utility doesn’t have to roll up to your house and install something, they can just pay you for access to it.

The DCIM advantage

What is data center infrastructure management all about? Syska Hennessy Group – MENA’s Greg Jasmin, co-managing director, and Robert Saunders, FM & commissioning lead, explain DCIM

Data center owners and operators are always looking for new ways to enhance daily operational efficiencies, and Data Center Infrastructure Management (DCIM) is the newest tool on the market. But, what is DCIM? What are its benefits?

While stand-alone infrastructure like a Building Automation System (BAS), Electrical Power Monitoring System (EPMS), IT network management and a building’s security system are all needed to monitor and control individual equipment at the local level, DCIM is the umbrella that can integrate all the local, independent systems into one dashboard providing a holistic view of the data center.

This ability to oversee the infrastructure and equipment integration aids in forecasting and trending, helping data center management to make informed decisions both on a daily basis and when capital investments arise.

DCIM can help answer questions like: How is the electrical system impacted if additional IT equipment is added or how much space is actually on the data center (DC) white floor? How much UPS and cooling capacity is left? What’s the network ratio? Where are my assets located in the DC?

While DCIM can provide data centers managers with a variety of useful tools, DCIM isn’t the magic bullet solution for each management challenge and may not be right for every data center. Instead, it’s important to fully understand both the prerequisites of a DCIM system and what it takes to sustain operations long term before determining if it’s appropriate for a specific facility.

DCIM solutions vary greatly in scope, price and systems architecture. Selecting the right DCIM solution is all about understanding how the DCIM solution will fit into the current operating culture.

With an increasing number of diverse products on the market right now, successful DCIM implementation requires a structured system selection and implementation process. Because there is no one size fits all data center, similarly an out-of-the-box DCIM package may not be the right solution either.

More typically, a DCIM solution will be selected by a qualified, third party DCIM consulting engineer that is knowledgeable in both critical facilities and information and communication technologies (ICT) integration.

IDC: Number of Data Centers To Decline After 2017

Changing IT needs will drive more enterprises away from in-house data centers to off-site facilities in coming years, according to a new forecast from the analyst firm IDC. The future will also see a rise in super-size “mega datacenters,” leading to a decline in the overall number of data centers around the world even as total data center space keeps growing, the report stated.

According to the IDC forecast, released earlier this week, the total number of data centers will peak at 8.6 million in 2017 and then start to decline. However, total data center space will increase globally, rising from 1.58 billion square feet in 2013 to 1.94 billion square feet by 2018.

The shift in the data center environment is being driven by rapidly accelerating data volumes and the need for increasingly flexible computing resources, according to IDC. As organizations look for ways to harness big data and stay competitive in a fast-paced, global economy, more and more are turning to off-site, managed and cloud-based IT services to help keep up.

Rise of the ‘Mega Data Center’

“Over the next five years, a majority of organizations will stop managing their own infrastructure,” said Richard Villars, IDC’s Vice President for Datacenter and Cloud Research. “They will make greater use of on-premise and hosted managed services for their existing IT assets, and turn to dedicated and shared cloud offerings in service provider data centers for new services. This will result in the consolidation and retirement of some existing internal data centers, particularly at the low end.”

Providers of outsourced data center services, in the meantime, will see growing demand for managed, colocation and cloud-based services. This will contribute to the continuing growth of mega data centers.

According to IDC, mega data centers will account for 72.6 percent of all the new floor space being added by service providers by 2018. By that time, mega data centers will also be providing 44.6 percent of the world’s new high-end data center space, compared to 19.3 percent in 2013.

Smart Software to Help you Save Energy

Reducing energy use is hard work. Wattics software turns complex energy data into clear, actionable insights. Savings guaranteed.

Saving energy at home, or in commercial & industrial buildings is a daunting task, but necessary for the future of our planet. Some companies have found commercially viable solutions for the residential market through smart thermostats – e.g. Nest, and customised insights, such as Opower. With regard to industrial settings: building management systems, energy monitoring and the use of energy consultancy are generally the way to go.

While automation provides obvious benefits, it usually has a cost and is limited to a subset of appliances e.g. heating equipment. The same applies for energy consultants and monitoring equipment, where an individual or company will need to invest now in order to achieve future savings. As a result not everybody can afford to have their energy saved.

Individuals and organisations can actually reduce their energy use at no cost if they learn to operate equipment efficiently. The question is how to ensure that equipment is properly operated at all times, so that you can immediately rectify relevant issues where necessary? Nowadays, one needs to be an expert with an eye for patterns and outlines in order to decipher energy data. This process requires plenty of time and so can be difficult to get done. The lack of simplified, contextual and real-time information is the major obstacle to operating equipment efficiently and realising the savings.


Wattics takes a unique approach by translating complex energy data into meaningful and accessible information, to assist individuals and organisations in implementing energy savings, operational improvements and making business decisions.

Instead of bills and dashboards with kWh figures (which are meaningless without context), Wattics software diagnoses power use 24/7. This allows Wattics to alert you as soon as a machine or set of appliances begin to experience energy inefficiency. Depending on urgency and preferred settings, individuals and organisations can now receive clear, actionable energy saving insights when they are needed most.

At a time when the electricity grid is being modernised to support new business models such as demand response and dynamic pricing, smart software which makes sense of complex data is becoming a much needed tool for helping individuals and organisations save money.

Wattics launched its Sentinel contextual analytics software at the Web Summit on Nov. 4, and is actively seeking mutually beneficial relationships with ESCOs, Resellers, Utilities, Grid Operators and Technology Companies. Get in touch with us now at wattics.com, we are excited to provide our technology and expertise to help your business.
