In particular, it does not account for different normal temperatures outside the data center. For example, a data center located in Alaska cannot be effectively compared to a data center in Miami.

A colder climate results in a lesser need for a massive cooling system. Cooling systems account for roughly 30 percent of consumed energy in a facility, while the data center equipment accounts for nearly 50 percent. In particular, if it happened to be in Alaska, it may get a better result.

Additionally, according to a case study on Science Direct , "an estimated PUE is practically meaningless unless the IT is working at full capacity". All in all, finding simple, yet recurring issues such as the problems associated with the effect of varying temperatures in cities and learning how to properly calculate all the facility energy consumption is very essential.

By doing so, continuing to reduce these problems ensures that further progress and higher standards are always being pushed to improve the success of the PUE for future data center facilities.

To get precise results from an efficiency calculation, all the data associated with the data center must be included. Even a small mistake can cause many differences in PUE results.

One practical problem that is frequently noticed in typically data centers include adding the energy endowment of any alternate energy generation systems such as wind turbines and solar panels running in parallel with the data center to the PUE, leading to an obfuscation of the true data center performance.

Another problem is that some devices that consume power and are associated with a data center may actually share energy or uses elsewhere, causing a huge error on PUE.

PUE was introduced in and promoted by The Green Grid a non-profit organization of IT professionals in , and has become the most commonly used metric for reporting the energy efficiency of data centres. The PUE metric has several important benefits.

First, the calculation can be repeated over time, allowing a company to view their efficiency changes historically, or during time-limited events like seasonal changes. Second, companies can gauge how more efficient practices such as powering down idle hardware affect their overall usage.

However, there are some issues with the PUE metric. The main one arises from the way the ratio is calculated.

Because IT load is the sole denominator, any reduction in IT load for example through virtualisation allowing some hardware to be stood down, or simply through more energy-efficient hardware will cause the PUE to rise.

This gives a perverse result. As well as the issues mentioned in the last paragraph, some other issues are the efficiency of the power supply network and calculating the accurate IT load. In practice, achieving a PUE of exactly 1. PUE is just one metric to evaluate data center energy efficiency.

Additional factors like water usage efficiency WUE and carbon usage effectiveness CUE may also be considered for a comprehensive assessment of environmental impact and resource efficiency.

In early supply chain challenges and sustainability were grabbing headlines: See this post for coverage. The focus on improving energy efficiency and reducing PUE has become increasingly important as pressures mount to consolidate data centers, accelerate cloud migration and reduce data storage costs , but to reduce the overall carbon footprint and contribute to sustainable IT operations.

Komprise cofounder and COO Krishna Subramanian published this article: Sustainable data management and the future of green business. Here is how she summarized the importance of unstructured data management to sustainability in the enterprise:. A lesser-known concept relates to managing data itself more efficiently.

Studies show a wide range of PUE values for data centers, but the overall average tends to be around 1. Data centers focusing on efficiency typically achieve PUE values of 1. PUE is the ratio of the total amount of power used by a computer data center facility to the power delivered to computing equipment.

Efficient power utilization -

However, the question of energy use in buildings is not straightforward as the indoor conditions that can be achieved with energy use vary a lot. The measures that keep buildings comfortable, lighting, heating, cooling and ventilation, all consume energy.

Typically the level of energy efficiency in a building is measured by dividing energy consumed with the floor area of the building which is referred to as specific energy consumption or energy use intensity: [32]. However, the issue is more complex as building materials have embodied energy in them.

On the other hand, energy can be recovered from the materials when the building is dismantled by reusing materials or burning them for energy. Moreover, when the building is used, the indoor conditions can vary resulting in higher and lower quality indoor environments. Finally, overall efficiency is affected by the use of the building: is the building occupied most of the time and are spaces efficiently used — or is the building largely empty?

It has even been suggested that for a more complete accounting of energy efficiency, specific energy consumption should be amended to include these factors: [33]. Thus a balanced approach to energy efficiency in buildings should be more comprehensive than simply trying to minimize energy consumed.

Issues such as quality of indoor environment and efficiency of space use should be factored in. Thus the measures used to improve energy efficiency can take many different forms.

Often they include passive measures that inherently reduce the need to use energy, such as better insulation. Many serve various functions improving the indoor conditions as well as reducing energy use, such as increased use of natural light.

A building's location and surroundings play a key role in regulating its temperature and illumination. For example, trees, landscaping, and hills can provide shade and block wind.

In cooler climates, designing northern hemisphere buildings with south facing windows and southern hemisphere buildings with north facing windows increases the amount of sun ultimately heat energy entering the building, minimizing energy use, by maximizing passive solar heating.

Tight building design, including energy-efficient windows, well-sealed doors, and additional thermal insulation of walls, basement slabs, and foundations can reduce heat loss by 25 to 50 percent.

Dark roofs may become up to 39 °C 70 °F hotter than the most reflective white surfaces. They transmit some of this additional heat inside the building.

US Studies have shown that lightly colored roofs use 40 percent less energy for cooling than buildings with darker roofs. White roof systems save more energy in sunnier climates.

Advanced electronic heating and cooling systems can moderate energy consumption and improve the comfort of people in the building. Proper placement of windows and skylights as well as the use of architectural features that reflect light into a building can reduce the need for artificial lighting.

Increased use of natural and task lighting has been shown by one study to increase productivity in schools and offices.

Newer fluorescent lights produce a natural light, and in most applications they are cost effective, despite their higher initial cost, with payback periods as low as a few months.

Effective energy-efficient building design can include the use of low cost passive infra reds to switch-off lighting when areas are unoccupied such as toilets, corridors or even office areas out-of-hours. Building management systems link all of this together in one centralised computer to control the whole building's lighting and power requirements.

In an analysis that integrates a residential bottom-up simulation with an economic multi-sector model, it has been shown that variable heat gains caused by insulation and air-conditioning efficiency can have load-shifting effects that are not uniform on the electricity load.

The study also highlighted the impact of higher household efficiency on the power generation capacity choices that are made by the power sector.

The choice of which space heating or cooling technology to use in buildings can have a significant impact on energy use and efficiency. Ground source heat pumps can be even more energy-efficient and cost-effective.

These systems use pumps and compressors to move refrigerant fluid around a thermodynamic cycle in order to "pump" heat against its natural flow from hot to cold, for the purpose of transferring heat into a building from the large thermal reservoir contained within the nearby ground.

The result is that heat pumps typically use four times less electrical energy to deliver an equivalent amount of heat than a direct electrical heater does. Another advantage of a ground source heat pump is that it can be reversed in summertime and operate to cool the air by transferring heat from the building to the ground.

The disadvantage of ground source heat pumps is their high initial capital cost, but this is typically recouped within five to ten years as a result of lower energy use.

Smart meters are slowly being adopted by the commercial sector to highlight to staff and for internal monitoring purposes the building's energy usage in a dynamic presentable format. The use of power quality analysers can be introduced into an existing building to assess usage, harmonic distortion, peaks, swells and interruptions amongst others to ultimately make the building more energy-efficient.

Often such meters communicate by using wireless sensor networks. Green Building XML is an emerging scheme, a subset of the Building Information Modeling efforts, focused on green building design and operation. It is used as input in several energy simulation engines.

But with the development of modern computer technology, a large number of building performance simulation tools are available on the market. When choosing which simulation tool to use in a project, the user must consider the tool's accuracy and reliability, considering the building information they have at hand, which will serve as input for the tool.

Leadership in Energy and Environmental Design LEED is a rating system organized by the US Green Building Council USGBC to promote environmental responsibility in building design. They currently offer four levels of certification for existing buildings LEED-EBOM and new construction LEED-NC based on a building's compliance with the following criteria: Sustainable sites , water efficiency , energy and atmosphere, materials and resources, indoor environmental quality, and innovation in design.

The following year, the council collaborated with Honeywell to pull data on energy and water use, as well as indoor air quality from a BAS to automatically update the plaque, providing a near-real-time view of performance. The USGBC office in Washington, D.

is one of the first buildings to feature the live-updating LEED Dynamic Plaque. A deep energy retrofit is a whole-building analysis and construction process that uses to achieve much larger energy savings than conventional energy retrofits.

A deep energy retrofit typically results in energy savings of 30 percent or more, perhaps spread over several years, and may significantly improve the building value.

Energy retrofits, including deep, and other types undertaken in residential, commercial or industrial locations are generally supported through various forms of financing or incentives.

Other rebates are more explicit and transparent to the end user through the use of formal applications. In addition to rebates, which may be offered through government or utility programs, governments sometimes offer tax incentives for energy efficiency projects.

Some entities offer rebate and payment guidance and facilitation services that enable energy end use customers tap into rebate and incentive programs. To evaluate the economic soundness of energy efficiency investments in buildings, cost-effectiveness analysis or CEA can be used.

The energy in such a calculation is virtual in the sense that it was never consumed but rather saved due to some energy efficiency investment being made. Thus CEA allows comparing the price of negawatts with price of energy such as electricity from the grid or the cheapest renewable alternative.

The benefit of the CEA approach in energy systems is that it avoids the need to guess future energy prices for the purposes of the calculation, thus removing the major source of uncertainty in the appraisal of energy efficiency investments. Industries use a large amount of energy to power a diverse range of manufacturing and resource extraction processes.

Many industrial processes require large amounts of heat and mechanical power, most of which is delivered as natural gas , petroleum fuels , and electricity. In addition some industries generate fuel from waste products that can be used to provide additional energy. Because industrial processes are so diverse it is impossible to describe the multitude of possible opportunities for energy efficiency in industry.

Many depend on the specific technologies and processes in use at each industrial facility. There are, however, a number of processes and energy services that are widely used in many industries.

Various industries generate steam and electricity for subsequent use within their facilities. When electricity is generated, the heat that is produced as a by-product can be captured and used for process steam, heating or other industrial purposes.

Advanced boilers and furnaces can operate at higher temperatures while burning less fuel. These technologies are more efficient and produce fewer pollutants.

Over 45 percent of the fuel used by US manufacturers is burnt to make steam. The typical industrial facility can reduce this energy usage 20 percent according to the US Department of Energy by insulating steam and condensate return lines, stopping steam leakage, and maintaining steam traps.

Electric motors usually run at a constant speed, but a variable speed drive allows the motor's energy output to match the required load. This achieves energy savings ranging from 3 to 60 percent, depending on how the motor is used.

Motor coils made of superconducting materials can also reduce energy losses. Industry uses a large number of pumps and compressors of all shapes and sizes and in a wide variety of applications.

The efficiency of pumps and compressors depends on many factors but often improvements can be made by implementing better process control and better maintenance practices. Compressors are commonly used to provide compressed air which is used for sand blasting, painting, and other power tools.

According to the US Department of Energy, optimizing compressed air systems by installing variable speed drives, along with preventive maintenance to detect and fix air leaks, can improve energy efficiency 20 to 50 percent.

Using improved aerodynamics to minimize drag can increase vehicle fuel efficiency. Reducing vehicle weight can also improve fuel economy, which is why composite materials are widely used in car bodies. More advanced tires, with decreased tire to road friction and rolling resistance, can save gasoline.

Fuel economy can be improved by up to 3. The design of a car impacts the amount of gas needed to move it through air. Aerodynamics involves the air around the car, which can affect the efficiency of the energy expended. Turbochargers can increase fuel efficiency by allowing a smaller displacement engine.

The 'Engine of the year ' is the Fiat TwinAir engine equipped with an MHI turbocharger. The performance of the two-cylinder is not only equivalent to a 1. Energy-efficient vehicles may reach twice the fuel efficiency of the average automobile. Cutting-edge designs, such as the diesel Mercedes-Benz Bionic concept vehicle have achieved a fuel efficiency as high as 84 miles per US gallon 2.

The mainstream trend in automotive efficiency is the rise of electric vehicles all-electric or hybrid electric. Electric engines have more than double the efficiency of internal combustion engines.

Plug-ins can typically drive for around 40 miles 64 km purely on electricity without recharging; if the battery runs low, a gas engine kicks in allowing for extended range. Finally, all-electric cars are also growing in popularity; the Tesla Model S sedan is the only high-performance all-electric car currently on the market.

Cities around the globe light up millions of streets with million lights. There are several ways to improve aviation's use of energy through modifications aircraft and air traffic management. Aircraft improve with better aerodynamics, engines and weight.

Seat density and cargo load factors contribute to efficiency. Air traffic management systems can allow automation of takeoff, landing, and collision avoidance, as well as within airports, from simple things like HVAC and lighting to more complex tasks such as security and scanning.

International standards ISO and ISO provide a documented methodology for calculating and reporting on energy savings and energy efficiency for countries and cities. The first EU-wide energy efficiency target was set in Member states agreed to improve energy efficiency by 1 percent a year over twelve years.

In addition, legislation about products, industry, transport and buildings has contributed to a general energy efficiency framework. More effort is needed to address heating and cooling: there is more heat wasted during electricity production in Europe than is required to heat all buildings in the continent.

Energy efficiency is central to energy policy in Germany. Recent progress toward improved efficiency has been steady aside from the financial crisis of — Efforts to reduce final energy consumption in transport sector have not been successful, with a growth of 1.

This growth is due to both road passenger and road freight transport. Both sectors increased their overall distance travelled to record the highest figures ever for Germany. Rebound effects played a significant role, both between improved vehicle efficiency and the distance travelled, and between improved vehicle efficiency and an increase in vehicle weights and engine power.

In , the German federal government released its National Action Plan on Energy Efficiency NAPE. The central short-term measures of NAPE include the introduction of competitive tendering for energy efficiency, the raising of funding for building renovation, the introduction of tax incentives for efficiency measures in the building sector, and the setting up energy efficiency networks together with business and industry.

In , the German government released a green paper on energy efficiency for public consultation in German. At the document's launch, economics and energy minister Sigmar Gabriel said "we do not need to produce, store, transmit and pay for the energy that we save".

In Spain, four out of every five buildings use more energy than they should. They are either inadequately insulated or consume energy inefficiently. The Unión de Créditos Immobiliarios UCI , which has operations in Spain and Portugal, is increasing loans to homeowners and building management groups for energy-efficiency initiatives.

Their Residential Energy Rehabilitation initiative aims to remodel and encourage the use of renewable energy in at least homes in Madrid, Barcelona, Valencia, and Seville.

It has the ability to reduce carbon emissions by 7, tonnes per year. Learn about common air pollutants. Fossil fuels are also often burned directly to heat our buildings, such as in furnaces and boilers, and for water heating and cooking.

This can impact indoor air quality in your home, as well as contribute to outdoor air pollution. By using energy more efficiently, we can help reduce emissions of greenhouse gases and other air pollution, fight the threat of climate change, and help to protect our health and the environment.

By lowering energy use, energy efficiency reduces monthly energy bills and makes energy more affordable for businesses and families. Some energy-efficient products cost more to buy than other options, but they typically save you money over the long term.

As you can see, the higher purchase price is more than offset by ongoing bill savings, reducing energy costs for consumers and businesses. Find information on rebates and other discounts.

By reducing monthly energy bills, energy efficiency can lessen the strain of paying for energy, especially for families with high energy burdens — meaning a larger percentage of their income goes to paying energy bills than the average household. Families experiencing energy insecurity can face the difficult choice between paying monthly energy bills or putting food on the table.

Energy efficiency can help households financially and improve the health, comfort, and safety of families in their homes.

In a room filled with racks of computers and other IT equipment a significant amount of your energy costs are incurred by specialized data center cooling and power equipment deployed to keep your servers and other IT equipment up and running.

Heat problems in data centers are a leading cause of downtime. Data Centers are large complex environments and often have different strategic teams managing key components-one team focusing on the facilities management and the other on IT Equipment deployed in the facility.

In these environments facilities managers usually determine infrastructure environmental issues including power, cooling, and airflow, and IT Managers determine critical IT systems such as servers and networking equipment.

They should be measured on a regular, if not real-time, basis at different times of the day and week. To stress this significance, the Green Grid is introducing some additional identifiers, which in combination with the PUE benchmark score will give you a much better picture on frequency and overall meaningfulness of the PUE or DCiE resulting score.

Measuring should be used as an ongoing tool in your overall data center strategy. CFD measurement at multiple heights in a row of racks along with air pressure measurement under floor tiles can not only help you insure that you are getting enough cool air to the inlet of your servers, it can help you maintain airflow to the recommended ASHRAE level to all IT equipment current ASHRAE inlet air recommendations are for environment range of 18°C to 27°C With proper power measurement of your overall data center IT equipment and infrastructure, you will be able to determine your PUE and DCiE.

It also helps you set a benchmark you can track, report, and continually improve. Keeping your data center energy efficient should be an ongoing process.

And as you add additional energy efficient IT assets, the process continues showing how much less energy consumption your facility is using.

The concepts of PUE and DCiE seem straightforward. Yet, the intricate maze of transformers, PDUs, and chillers make the measurement more than simple arithmetic. Calculating PUE or DCiE has more value when it becomes a repeatable process, tracked over time. The content herein is designed to assist data center professionals with that first reading, developing a protocol to repeat as efficiency efforts carry on.

If data collection is automated through software, continuous measurement hour to hour, minute to minute should be possible. Loads can fluctuate throughout the work day, and professionals may find value in contrasting PUE at peak loads with the measurement at slower or idle points of the day.

Whether the calculations happen once a month or once an hour, any regular measurement is a step in the right direction. A dedicated data center, for instance, may capture incoming electricity straight at the meter and the IT Load straight from the UPS.

From there, simple division yields an efficiency score. But a number of components influence the total facility load. For this reason, a user may want to specifically measure and trend consumption in the central plant. Current technologies enable very precise measurements.

A building management system may be able to monitor total incoming electricity, chiller loads, and lighting loads. Remote sensors and software products can monitor kW and kWH of individual CRACs and CRAHs. As a result, users can target and improve problem areas of the data center. This level of detail ultimately depends on your goals, facility, and budget.

No matter how simple or involved the program, the most important objective is consistency. You cannot improve or control what you do not measure. Electrical distribution is central to these measurements. Power flows through assorted components, and losses occur as it makes its way from a service entrance to the IT equipment.

Energy efficiency is utiliization use of less energy to Promote wound healing the same task or produce the utilizatino result. Efficient power utilization homes and buildings use less energy to EEfficient, Efficient power utilization, and run appliances and electronics, and energy-efficient manufacturing facilities use less energy to produce goods. Energy efficiency is one of the easiest and most cost-effective ways to combat climate change, reduce energy costs for consumers, and improve the competitiveness of U. Energy efficiency is also a vital component in achieving net-zero emissions of carbon dioxide through decarbonization. The U.
