>” […] Lighting Control Facilitates Load-shed Strategies

Load shed, or the ability to quickly reduce electricity use during peak periods, is critical to ensuring microgrid reliability. Because lighting uses a considerable proportion of building peak electrical loads (30% of peak electricity),1 and because reduced light levels deliver immediate reductions in electricity, lighting control is one of the simplest and most predictable demand response solutions.

The reduction of lighting load also provides a reduction in HVAC cooling load during the summer, which is the most common peak electrical period.  Furthermore, since dimming is typically unobtrusive when it is executed over a period of time (as little as 10 seconds), lighting control is a viable option for immediate emergency response.

Dimming as a load shed strategy is highly effective because the human visual system has the ability to accommodate a wide variety of light levels with minimal effect on the occupants2,3.  When a demand reduction is required a gradual dimming of electric lighting can reduce light levels by 35 percent before 20 percent of the occupants attempt to intervene.  Response time is essentially instantaneous, typically has little impact on occupant comfort, and demand savings from lighting are more predictable than those from HVAC response.

Light management systems have the capability to automatically trigger a demand response event from a utility signal or from time clock scheduling. Therefore, a predictable and effective demand response strategy can be automatically implemented while going virtually unnoticed to the building occupants.

Energy codes, standards, and green building certifications such as ASHRAE (American Society of Heating, Refrigerating, and Air Conditioning Engineers) 90.1, IECC (International Energy Conservation Code), California Title 24, ASHRAE 189, IgCC (International Green Construction Code), or LEED (Leadership in Energy and Environmental Design) now include lighting controls as a part of a whole-building energy strategy.

There are subtle differences for each code/standard/certification, but some general requirements and/or credits include: required lighting control for most areas (manual or automatic), automatic lighting shut-off, some automatic receptacle shut-off, daylight controls for daylit spaces, automatic shut-off of exterior lighting during daytime hours, and various levels of occupancy/vacancy control. As a result of buildings updating their basic lighting control infrastructure to meet code, they are increasingly becoming capable of connecting to a microgrid, without the need for additional significant investments.

>” […]“Lower expenditures on energy management in the small and medium-sized building market, along with the lower penetration of advanced controls and building management systems, has limited the penetration of BEMS in this sector,” said Noah Goldstein, research director with Navigant Research. “Given the increasing importance of energy savings, however, BEMS are poised to be a tool that enables savings in both cost and carbon emissions in small and medium buildings.”

The most rapid growth in the BEMS market for smaller buildings, according to the report, is expected to occur in Europe and Asia Pacific, where new construction and regulation are promoting the installation of BEMS equipment and in turn creating demand for associated services and software. In the North American market, BEMS sales are expected to be concentrated in software, driven by utility and regulatory initiatives that promote energy efficiency and building energy reporting.

Electric Vehicle Market – Nissan Tests “Demand Response” Energy Management System

Posted on by

Nissan is assessing the potential of electric vehicles in energy management systems. […]  is participating in the “demand response” energy supply and demand system testing together with businesses and government authorities in Japan.

Source: green.autoblog.com

>”[…]  Demand response is a strategy to make power grids more efficient by modifying consumers’ power consumption in consideration of available energy supply. Since the Great East Japan Earthquake in March 2011 the supply and demand of electricity during peak use hours in Japan has drawn attention. Under the demand response scheme, power companies request aggregators* to use energy conservation measures, and they are compensated for the electricity that they save.

Usually when energy-saving is requested consumers may respond by moderating their use of air conditioning and lighting. However, by using the storage capacity of electric vehicles and Vehicle to Home (V2H) systems, consumers can reduce their use of power at peak times without turning off lights and appliances. This is particularly useful in commercial establishments where it is difficult to turn power off to save electricity.

The demand response scheme involves assessing the usefulness of energy-saving measures using V2H systems during peak-use periods and analyzing the impact of monetary incentives on business. For example, the testing involves a LEAF and LEAF to Home system which is connected to power a Nissan dealer’s lighting system during regular business hours using stored battery energy. This reduces electricity demand on the power grid. The aggregator is then compensated for the equivalent of the total amount of electricity that is saved. Two or three tests per month will be conducted on designated days for three hours’ each time sometime between 8:00 a.m. to 8:00 p.m. from October 2014 through January 2015.

Effective use of renewable energy and improvements in the efficiency of power generation facilities will enable better energy management in the future and help reduce environmental impact. Field tests using EVs’ high-capacity batteries that are being conducted globally are proving their effectiveness in energy management. Additionally, if similar compensation schemes for energy-saving activities were applied to EV owners it could accelerate the wider adoption of EVs and reduce society’s carbon footprint.

Nissan has sold more than 142,000 LEAFs globally since launch. The Nissan LEAF’s power storage capability in its onboard batteries, coupled with the LEAF to Home power supply system, is proving attractive to many customers. As the leader in Zero Emissions, Nissan is promoting the adoption of EVs to help build a zero-emission society in the future. Along with these energy management field tests, Nissan is actively creating new value through the use of EVs’ battery power storage capability and continuing to promote initiatives that will help realize a sustainable low-carbon society.

* Aggregators refers to businesses that coordinate two or more consumers (e.g. plants and offices) and trade with utility companies the total amount of the electricity they have succeeded in curbing.”<

Intelligent Efficiency: Evolution of the Energy Efficiency Market

Posted on by
Reply

In the past, energy efficiency was seen as a discrete improvement in devices,” says Skip Laitner, an economist who specializes in energy efficiency. “But information technology is taking it to the next level, where we are thinking dynamically, holistically, and system-wide.

Source: www.greentechmedia.com

>” […] This emerging approach to energy efficiency is information-driven. It is granular. And it is empowering consumers and businesses to turn energy from a cost into an asset. We call this new paradigm “intelligent efficiency.”

That term, which was originally used by the American Council for an Energy-Efficient Economy in a 2012 report, accurately conveys the information technology shift underway in the efficiency sector.

The IT revolution has already dramatically improved the quality of information that is available about how products are delivered and consumed. Companies can granularly track their shipping fleets as they move across the country; runners can use sensors and web-based programs to monitor every step and heartbeat throughout their training; and online services allow travelers to track the price of airfare in real time.

Remarkably, these web-based information management tools are only now coming to the built environment in a big way. But with integration increasing and new tools evolving, they are starting to change the game for energy efficiency.

Although adoption has been slow compared to other sectors, many of these same technologies and applications are driving informational awareness about energy in the built environment. Cheaper sensors are enabling granular monitoring of every piece of equipment in a facility; web-based monitoring platforms are making energy consumption engaging and actionable; and analytic capabilities are allowing companies to find and predict hidden trends amidst the reams of data in their facilities and in the energy markets.

This intelligence is turning energy efficiency from a static, reactive process into a dynamic, proactive strategy.

We interviewed more than 30 analysts and companies in the building controls, equipment, energy management, software and utility sectors about the state of the efficiency market. Every person we spoke to pointed to this emerging intelligence as one of the most important drivers of energy efficiency.

“We are hitting an inflection point,” says Greg Turner, vice president of global offerings at Honeywell Building Solutions. “The interchange of information is creating a new paradigm for the energy efficiency market.”

Based on our conversations with a wide range of energy efficiency professionals, we have identified the five key ways intelligent efficiency is shaping the market in the commercial and industrial (C&I) sector:

The decreased cost of real-time monitoring and verification is improving project performance, helping build trust among customers and creating new opportunities for projects;Virtual energy assessments are bringing more building data to the market, leveraging new lead opportunities for energy service professionals;Web-based energy monitoring tools are linking the energy efficiency and energy management markets, making efficiency a far more dynamic offering;Big data analytics are creating new ways to find trends amidst the “noise” of information, allowing companies to be predictive and proactive in efficiency;Open access to information is strengthening the relationship between utilities and their customers, helping improve choices about efficiency and setting the foundation for the smart grid.

Superstorm Sandy crippled much of New Jersey’s critical infrastructure two years ago. Stuck without power at home, many also couldn’t get to work because the operations center for New Jersey Transit flooded, damaging backup power systems, emergency generation, and the computers that control train operations.

Source: theenergycollective.com

>” […] After a highly competitive grant process, NJ Transit last week received $1.3 billion in federal funds to improve the resilience of the state’s transportation system in the event of devastating future storms. The funds include $410 million to develop the NJ TransitGrid into a first-of-its-kind microgrid capable of keeping the power running when the electric grid goes down.

Microgrids are different from traditional electric grids in that they generate electricity on-site or nearby where it’s consumed. They can connect to the larger grid or island themselves and operate independently.

The NJ TransitGrid will not only generate power on-site but will incorporate a range of clean energy technologies such as renewable energy, energy storage, and distributed generation. This microgrid will also allow NJ Transit and Amtrak trains running on Amtrak’s Northeast Corridor, the country’s busiest train line, to keep operating during an outage.

Environmental Defense Fund joined state and federal stakeholders, such as New Jersey Governor’s Office of Recovery and Rebuilding and the U.S. Department of Energy, in the early stages of NJ TransitGrid planning. EDF also wrote a letter in support of New Jersey’s application for the funds from the Federal Transit Administration.

The $1.3 billion in total federal funds received by NJ Transit will go toward a range of resiliency and restoration projects across the system, including flood protection, drawbridge replacement, train storage and service restoration, and making train controls more resilient. These funds will also be used to fortify critical Amtrak substations.

Serving almost 900,000 passengers daily, NJ Transit is the third largest transit system in the country connecting travelers to the tri-state area of New York, New Jersey, and Pennsylvania. An independent microgrid for NJ Transit will prepare the state for future extreme weather events, which are happening more frequently due to climate change. Furthermore, the use of clean energy resources will make this microgrid a less polluting and more efficient operation for New Jersey’s day-to-day needs.”<

6 Schemes to Implement for Plant ISO 50001 Certification

Posted on by

During a webcast  […] representatives from the US Department of Energy and Underwriters Laboratories walked through the details of the just-released energy management standard, and how companies can get on board, quickly.

Source: www.greenbiz.com

>”When the standard achieves widespread adoption, it’s estimated that ISO 50001 could influence up to 60 percent of the world’s energy use.  […]

ISO 50001 requires continuous improvement, but not specific requirements, which is where the ITP program comes in, to have specific requirements of improvement. The value of the certification, Scheihing said, is that for the first time it provides a framework for continual improvement for facilities on energy performance, and across the entire organization.

To be certified, you have to conform to the ISO 50001 management standard, and you have to improve your energy performance, and get both aspects certified under a third party. There are 24 companies working in the pilot mode of ISO 50001, across all types of manufacturing sectors and at all sizes.

Between 2008 and 2010, five initial facilities in Texas were piloted, and have been certified to date. Scheihing said the energy improvements achieved at the facilities ranged from 6.5 percent to 17.1 percent over a three-year period.

Among the initial feedback from the pilot project include the benefits of having a cross-functional plant energy management team that goes beyond just operations or engineering means that energy management becomes a shared responsibility, and that makes it much easier to incorporate significant changes in energy use.

One of the biggest shifts that the pilot projects found was that as a result of going through ISO 50001 certification, energy management became a way of doing business, instead of a project-by-project undertaking.  […]

 

Scheihing laid out six steps that any organization can take to get started on ISO 50001 today:

Secure support from top management;Collect, track, and analyze energy data;Identify key energy uses;Establish a baseline;Identify energy-saving opportunities;Prioritize opportunities

The Department of Energy has created a new website for energy management, which lays out an overview of ISO 50001 and offers case studies and tools to help companies undertake those first steps.

Jerry Skaggs from UL DQS followed on Scheihing’s presentation to walk through each of the six steps, as well as a checklist for organizations to follow once they’ve gone through the process to ensure proper implementation and follow-through.

In the end, there are a number of benefits to effectively implement an energy management system, including:

• Reduced operational and overhead costs lead to increased profitability
• Reduced air emissions, such as GHGs
• Increased efficiency of energy sources
• Increased assurance of legal, internal compliance
• Variables affecting energy use and consumption are identified
• Increased understanding of energy use and consumption via defined methods, processes of data collection

UL DQS, which brings the Management Systems Solutions division of Underwriters Laboratories together with DQS, a German management certification company, offers a number of specialized services for helping companies assess and implement opportunities for energy management, including ISO 50001 certification.  […] “<

>”Washington /PRNewswire / – Three North American industrial plants that recently deployed energy management systems (EnMS) are highlighted in new case studies from the Global Superior Energy Performance (GSEP) Energy Management Working Group (EMWG). These latest entries in the growing GSEP series explain how two Canadian plants, IBM and Lincoln Electric, and one U.S. plant, HARBEC, Inc., deployed ISO-compliant systems to manage their energy more efficiently while boosting competitiveness. GSEP, an initiative of the Clean Energy Ministerial, publishes the series in an effort to improve energy efficiency and mitigate carbon emissions around the globe.

U.S. Case Study HARBEC, Inc. improved the energy performance of its specialty plastics manufacturing plant in upstate New York by 16.5%, primarily by managing its combined heat and power unit more efficiently. The plant’s verified conformance with the international energy management standard ISO 50001 and its sustained improvements in energy performance earned HARBEC Platinum certification from the U.S. Superior Energy Performance (SEP) program, administered through the U.S. Department of Energy. […]

The USD$127,000 invested to implement SEP was paid back by the resulting operational energy cost savings within 2.4 years. The EnMS now saves the plant 6 billion Btu (6,300 gigajoules) annually and lowers energy costs by USD$52,000 each year at prevailing energy prices. HARBEC’s real-time automated system continuously monitors plant equipment to sustain and continuously improve energy performance. […]

Canadian Case Studies: (1)  IBM implemented an EnMS at its manufacturing facility in Bromont, Quebec, which helped it to reduce energy consumption by 9.2% and save CAD$550,000 in 2013. The savings came from 36 energy efficiency projects implemented as part of the EnMS. Tool modifications generated approximately 27% of the savings, while heating, ventilation, and air conditioning and exhaust reduction projects generated the other 73%. Equipment throughout the plant is now monitored using dashboards that show real-time energy use. View IBM case study.

With the support of Natural Resources Canada (NRCan), IBM Bromont was certified for conformance with CAN/CSA ISO 50001 in 2013. NRCan’s Canadian Industry Program for Energy Conservation provided plant staff with various energy conservation tools and services that assisted with EnMS development and certification.

(2)  Lincoln Electric became CAN/CSA ISO 50001 certified after implementing an EnMS at its facility in Toronto, Ontario, which manufactures steel welding wire and industrial diesel-driven DC generator welding machines. With the help of NRCan, Lincoln Electric developed an EnMS that reduced the facility’s energy consumption by 22% in 2013. […]

Plant management was initially interested in an EnMS as a means to maintain competitiveness and reduce risks associated with volatile energy prices. The company learned that its successful EnMS implementation owes much to its corporate culture that actively encourages the identification of energy improvements and conservation measures. The plant expects its EnMS to lead to continuous improvement in overall plant energy consumption. […]”<

Methods of Improving Data Centers’ Energy Efficiency and Performance

Posted on by

America’s data centers are consuming — and wasting — a surprising amount of energy.

Source: www.livescience.com

>”Our study shows that many small, mid-size, corporate and multi-tenant data centers still waste much of the energy they use. Many of the roughly 12 million U.S. servers spend most of their time doing little or no work, but still drawing significant power — up to 30 percent of servers are “comatose” and no longer needed, while many others are grossly underutilized. However, opportunities abound to reduce energy waste in the data-center industry as a whole.  Technology that will improve efficiency exists, but systemic measures are needed to remove the barriers limiting its broad adoption across the industry.

How much energy do data centers use?

The rapid growth of digital content, big data, e-commerce and Internet traffic more than offset energy-efficiency progress, making data centers one of the fastest-growing consumers of electricity in the U.S. economy, and a key driver in the construction of new power plants. If such data centers were a country, they would be the globe’s 12th-largest consumer of electricity, ranking somewhere between Spain and Italy.

In 2013, U.S. data centers consumed an estimated 91 billion kilowatt-hours of electricity. That’s the equivalent annual output of 34 large (500-megawatt) coal-fired power plants — enough electricity to power all the households in New York City, twice over, for a year.  […]

Fixing the problem

While current technology can improve data center efficiency, we recommend systemic measures to create conditions for best-practices across the data center industry, including:

Adoption of a simple, server-utilization metric. One of the biggest efficiency issues in data centers is underutilization of servers. Adoption of a simple metric, such as the average utilization of the server central processing units (CPUs), is a key step in resolving the energy-consumption issue.  […]

Rewarding the right behaviors. Data center operators, service providers and multi-tenant customers should review their internal organizational structures and external contractual arrangements and ensure that incentives are aligned to provide financial rewards for efficiency best practices.  […]

Disclosure of data-center energy and carbon performance.Public disclosure is a powerful mechanism for demonstrating leadership and driving behavior change across an entire sector. […]

If just half of the technical savings potential for data-center efficiency that we identify in our report is realized (taking into account market barriers), electricity consumption in U.S. data centers could be cut by as much as 40 percent.  […]”<

In California, brokers are at the heart of every non-residential sale or lease. Can the AIR organization get them on board with benchmarking?

Source: www.greenbiz.com

>”Commercial buildings are some of California’s largest energy- and water-guzzlers. With 58 percent of the state locked in the highest category of drought, many commercial property owners are seeing increased utility bills, and with a new building energy benchmarking and disclosure law on the books, building owners seek energy efficiency solutions as a common-sense way to ease some of the pressure. One key trade association in California, the AIR Commercial Real Estate Association, is taking the lead by educating its members on the benefits of energy efficiency.

AIR, founded in 1960, is a regional commercial real estate brokers association with more than 1,700 members across southern California, and is one of the nation’s largest organizations of its kind. It’s recognized across the U.S. for its ever-expanding library of sample lease forms, which members use to stay updated on industry and lease language trends — several of which now include sustainability. When California’s energy benchmarking law, AB 1103, went into effect in January, AIR responded by creating sample energy disclosure lease and sale addenda (PDF) and began educating its members on these new tools.

Brokers are in the thick of it

The law states that any time a non-residential building owner finances, sells or leases a whole building, the property owner is required to use Energy Star portfolio manager to benchmark the building and provide the Energy Star rating and supporting consumption information to the lender, buyer or tenant in the transaction. As brokers are central to every aspect of a commercial transaction, their participation is essential for the law to have its intended effect. AIR’s lease and sale addenda effectively address these energy disclosure requirements in one document, providing real estate professionals, building owners, tenants and attorneys with a framework template for compliance with the regulation.

Brokers hold the key to increasing stakeholder awareness, potentially boosting compliance rates, benchmarking data quality and ultimately better building performance and energy management — and educating the community about new regulations and tools is essential to unlocking this potential.”<

CEC Delays Energy Benchmarking and Disclosure Requirements 2 Years for Smaller Buildings

Posted on by
Reply

 

>”[…]Compliance with AB 1103 is not suspended, and will continue to be required, for the sale, lease, or financing of buildings over 10,000 square feet that are otherwise subject to the regulations based upon occupancy type.

Significant barriers to compliance with AB 1103

An Emergency Rulemaking Action requires a description of specific facts justifying the immediate action. In justifying the two-year delay, the CEC explained that several stakeholders had expressed concerns about significant barriers to compliance with AB 1103. The CEC noted the following factors in justifying the two-year delay:

  • Some utilities have required tenant consents before releasing utility usage data despite letters sent from the CEC to utilities in July 2013 prohibiting such requirement. This requirement to obtain tenant consents significantly increases compliance costs.
  • Smaller utilities have expressed concerns with their ability to comply given limited staff and resources.
  • The Portfolio Manager platform and software has experienced significant technical problems.
  • The expansion in scope to smaller buildings would increase the number of compliance requests received by utilities, impeding their ability to address barriers to compliance.
  • Smaller building owners may lack the expertise, resources, or capacity necessary to overcome current barriers to compliance without incurring undue expense.
  • Based on initial disclosure data following the January 1, 2014 implementation, it became apparent that “the required disclosures were not being made for the majority of transactions for which they were required.”
  • The development of best practices approaches is lowering compliance costs and paving the way to greater compliance. The additional two years will facilitate lower costs and higher compliance rates before further expanding the program to smaller buildings.”<
