European Energy Label For Led Lights

There are many certainties in life, like taxation and electricity bills for example. Another is that whenever you buy an electrical appliance you will always find a European Energy Label somewhere on it. This is because all European manufacturers and retailers must tell you about the energy efficiency of electrical appliances. Regardless of whether you’re buying a fridge, washing machine, dishwasher, oven or light bulb, the EU Energy Label will help you to make informed decisions about the purchase of energy-consuming appliances.

Put simply, the EU Energy Label is a labeling scheme that provides clear and easily recognizable information about the energy consumption and performance of a product. The label is a mandatory requirement and must be clearly displayed on white goods, light bulb packaging and cars when offered for sale or rent.

The main element of the label is an energy efficiency rating scale. This takes the form of a simple, brightly colored, index labeled from A to G. Each of these is a discrete ‘energy efficiency class’ with A being the most efficient and G being the least efficient. With the advent of energy saving technologies, in July 2004 the energy efficiency rating category for A for refrigeration products was divided into 3 separate categories; A, A+ and A++.

The label also provides more general information relating to the product that allows a customer to draw direct comparisons between models.

In the particular case of light bulbs, in addition to the energy efficiency categories, you will find three pieces of important information. The first is the bulbs luminous flux, measured in Lumens. The second is the electricity consumption in watts. The last is the average lifespan in hours.

All of the LED Light Bulbs are classified as A Energy Rated. All light bulb electrical consumptions are calculated relative to a standard. Because the LED Bulbs are rated A they use between 20 and 50 per cent of the energy of this standard, making them impressive little energy savers.

So when you are out looking for electrical products keep your eyes peeled for the EU Energy Label.

Also, do not hesitate if you wish to comment on any of the articles and want to express your views in general.

Bipartisan Energy Efficiency Bill On Verge Of Senate Breakthrough

While many in Washington still warn about the dangers of carbon emissions and climate change, the reality and perhaps the one thing that experts on both sides agree on, is that Americans are paying less attention to global warming than they have in the past. To end this uncertainty, the Senate after months of behind the scenes maneuvering will begin the debate on the critically important legislation which could help American consumers, businesses and the federal government to save millions of dollars each year by using less energy, and using less energy will be a step forward in the fight against climate change in the U.S.
The new energy efficiency legislation introduced by Senators Shaheen and Portman could come up before the U.S. Senate for approval. The Energy Savings and Industrial Competitiveness Act, also known as Shaheen-Portman Bill will help to reduce the energy bill of U.S., improve its economic competitiveness, create new American jobs and enhance U.S. energy security. The bill has been endorsed by more than 200 businesses, trade associations and advocacy groups.
What is the Energy Savings and Industrial Competitiveness Act?
The Shaheen-Portman Energy Efficiency Bill passed the Senate Energy and Natural Resources Committee by a 19-3 vote, it includes provisions that will directly improve energy efficiency in buildings, industrial processes and federal agencies, the provisions in the bill include strengthening energy efficiency requirements in building energy codes, incentivizing energy efficiency using rebates and for certain equipment, encouraging energy efficiency supply chains through a new supply star program.
The American Council for an Energy Efficient Economy (ACEEE) found implementation of the bill would save about 9.5 quadrillion btus (british thermal units) between 2014 and 2030, or nearly one tenth of the annual energy use in the U.S. As the second largest consumer of energy in the world and the worlds biggest economy it is critically important for the United States to improve energy efficiency, the bill has received bipartisan support with seven Republicans and twelve Democrats in favor of the bill. It contains a variety of policies and programs to reduce residential, commercial and industrial energy use and focusing on sectors and areas with energy savings potential such as the residential, commercial and industrial sectors, the bill also restricts inefficient energy practices that will cost the U.S. economy billions of dollars and millions of jobs every year. One of the components of the bill also requires the Federal Government- which is the largest user of energy adopt energy saving techniques and best practices to operate efficiently.
Commenting on the bill Senator Portman said Washington can seem pretty divided these days, but there are some things on which we all can agree. This bill is one of them it is good for the economy and good for the environment. By making it easier for employers to use energy efficient tools, we are helping them to reduce their costs, enabling them to put those savings towards expanding their companies and hiring new workers.
The bill has received positive feedback and widespread support, the only constraint halting the success of the bill are the amendments lawmakers are trying to attach to it. The successful passing of this bill will not only help in mitigating climate change in the U.S. and reduce carbon emissions but also be a trendsetter for other countries to follow suit.

Which Windows Buyers Guide To Establishing The Energy Efficiency Of Replacement Windows

Energy efficient windows will not only help to reduce your heating bill, they also increase comfort and help the environment through a lower carbon footprint. They can be made using any frame material or combination of materials. A good tool to establish whether replacement windows are energy efficient is the British Fenestration Rating Council’s (BFRC) scheme for rating the energy efficiency of windows. This is a national system and is accepted as a method to show compliance with the building regulations for new or replacement window installations. However, at present the scheme is still voluntary.

The energy rating scheme uses traffic light energy labels for windows on a scale from A to G that are similar to the energy labels you can find on most household appliances. A-graded windows are the most energy efficient. Each window rated by the BFRC has a unique label displaying the overall rating (A-G) and the energy index which shows how much energy the window will save or lose once it has been installed. This depends on a number of factors such as the building, local climate and indoor temperature. A positive value in the index indicates that the window lets more heat in through the glass into the room than is being lost through the window. Such a window is a free energy supplier. A-rated windows will have a positive energy index. Values are given in kilowatt hours per square metre per year.

The label also shows the window’s U and L values. These are measures of a window’s ability to reduce heat loss during indirect radiation exposure during the winter. Low U values mean less heat loss and translate into lower heating costs. The L value indicates the effective heat loss due to air penetration. Another value shown is the solar heat gain. This value is closely linked to the U value and measures the window’s ability to reduce heat gain during direct radiation exposure in the summer. A lower value means less direct heat enters the room and it stays cooler.

The type of glass used has a direct impact on the U value and the solar gain factor. The most energy efficient glass for double glazing is low emissivity (Low-E) glass. This often has an invisible coating of metal oxide on one of the two sheets of glass that make the window, normally on one of the internal panes. This makes the glass reflective, letting sunlight and heat in and cutting the amount that can get out again, thus making the home warmer in the winter. In the summer it reflects the heat back and makes your home cooler.

Very energy efficient windows might use gases like argon, xenon or krypton in the gap between the sheets of glass. The more efficient windows will also use pane spacers around the inside edges to keep the two panes of glass apart that contain little or no metal.

Selecting energy efficient windows has become easier as you can compare window energy ratings. The window energy rating scheme checks all components of the window (including the frame and any casement) and rates the whole window on its energy saving properties. Windows rated B or better are endorsed by the Energy Saving Trust. Energy labels allow you to compare and select windows based on their specific energy performance rather than just relying manufacturers’ claims, thus enabling you to make informed purchasing decisions.

Flexidry Enhancing Energy Efficiency For Modernahus, The New Green Housing Solution For The Uk

ModernaHus, the new generation of energy efficient green homes for the UK, will have 9500sm of its underfloor heating screeded with FlexiDry F1/7 day dry floor screed.

ModernaHus is being introduced in the UK after long trials by Scandinavian builders, Skanska. This innovative green home solution has already been adapted by several countries across Europe, and has been in the test phase in the UK for several years.

After two years of trials and considerable adaptation to suit the UK market and environment, the ModernaHus UK project is now underway and is scheduled for completion by October 2011.

The first phase of the ModernaHus UK project will comprise of 108 one to four bedroom residential units, in a rejuvenated site in Coldharbor Lane, Brixton. A good majority of the construction elements will be manufactured offsite and delivered to the site, ready for installation. This prefabricated building system has been found to be successful in bringing down the effective construction time while ensuring site safety as well as quality and finish of the products.

For energy efficiency, ModernaHus combines a well insulated building envelope, under floor heating, ground source heat pumps, solar panels and a central biomass boiler. The ModernaHus homes which will be 30% more efficient than normal homes, has obtained the Code for Sustainable Homes, Level 4.

With energy efficiency figuring as the priority for modern buildings, FlexiDry fast drying floor screeds is one of the screeds that is very much in demand by most major builders. When underfloor heating system can enhance energy efficiency, the use of the right screed is found to compound its effectiveness by acting as a thermal mass to dissipate the heat. FlexiDry floor screeds act as very good thermal conductors of heat and cut down the thermal losses and reduce the amount of heat required at the source. With an efficiency of 20-30% more than the normal anhydrite screeds, and drying times as less as 3 days to 21 days, FlexiDry is currently the chosen name for most of the major projects like ModernaHus.

Line Losses A Different Kind Of Energy Efficiency

It’s a homeowner’s responsibility to make sure that he or she is using appliances that are energy efficient. Replacing a twenty-year-old refrigerator is likely to reduce your electricity bill because a new ENERGY STAR-rated icebox has been designed to do more while using less of the juice. Energy efficiency, however, is not just a concern for the little guy. Utility companies must worry about “line losses,” the electricity that is lost as a result of the inherent inefficiency of the generation and transmission system. In places like Texas and New York, however, engineers are thinking of ways to prevent this waste. Best of all, the savings will be passed on to you, the consumer.

What causes this loss of energy in the first place? There are many reasons, including the flaws in electrical cables and the natural tendency toward entropy. (That’s the principle that says that systems tend to become more disordered over time.) Jim Landers, a columnist for the Dallas Morning News, explains that small amounts of electricity turn into heat as it runs through a conductor. This is one of the reasons that power adaptors can feel warm to the touch when you try to unplug them. This unwanted heat isn’t such a big deal for appliances with short cables. When you think of power transmission cables and the hundreds of miles they can traverse, you can understand why line losses are such a big concern.

In Texas, line loss results in the waste of 6.5% of all the Texas electricity generated in the Lone Star State. While that might not sound like very much, it starts to add up when you think of it in terms of your pocketbook. For every one hundred dollars you pay for Texas electricity, inefficiencies account for $6.50. One way to reduce that amount is to replace old, lower capacity transmission cables with more advanced lines that can handle the kind of high voltages that keep the lights on in modern cities. Landers note that there are plans in place to connect the wind farms of West Texas to the rest of the state via 345-kilovolt lines that boast only 4% inefficiency.

Much like Texans, New Yorkers know what it’s like to need a vast supply of reliable New York electricity. To reduce the effect of line losses, engineers have developed synchrophasors. According to the North American SynchroPhasor Initiative (NASPI), computers can measure voltage running through a line at very high speed. With this detailed information about the flow of energy, utilities can better manipulate the grid to reduce the stress on the system and eliminate some of that waste. For example, if a power plant malfunctions, thereby causing the voltage in the system to fluctuate, the use of synchrophasors allows authorities to quickly address the situation before it causes increased waste. (Or worse, an interruption in supply.)

Matthew L. Wald, a writer for the New York Times, sees the benefits of synchrophasors, reminding readers that current monitoring devices only provide measurements every two to four seconds. The kind of synchrophasors that are being installed in New York and in the Midwest are able to provide feedback thirty times a second, allowing computers to regulate energy flow more fortuitously.

The devices themselves aren’t too expensive: approximately two to three thousand dollars for each synchrophasor. The real cost is derived from the computer and networking system that allows it to interact with the energy grid. Some of this money comes from the Energy Department, but even if residents end up paying to equip the grid with this technology, it’s the kind of wise long-term strategy that will result in long-term savings.

While it certainly will not be cheap to invest so much to establish a more efficient electric grid, it’s also a vital part of a greener future. Wind farms and solar facilities are (just like old-fashioned natural gas and coal power generation plants) often located far away from densely populated areas. As a result, utilities must run miles and miles of cable, resulting in greater line loss. If alternative energies can be more easily worked into the grid, we’ll all save money and enjoy a healthier environment. So the next time you read about improvements being made by state or local electric utilities, remember that something as simple as the cable strung between your home and the power plant can have a big effect on your monthly bill.

Energy-efficiency Electronics Hardware A bridge Fuel To The Future

Demand for energy continues to be a major topic around the world. Renewable energy sources such as wind, solar or hydro power are increasingly being utilized to provide for that demand. Many States have even recently passed laws raising the minimum renewable usage cap that utility companies must implement into their overall supply. But … we still require escalating amounts of energy for agriculture, industry, and to heat our homes and offices. Emerging as a “bridge fuel” to clean energy and renewable resources, the power electronics industry is poised to span that gap with hardware solutions needed to build intelligent power systems.

The Obama administration plans to spend billions of dollars on power conservation and sustainable energy projects as part of a $787 billion stimulus package which is has focused on energy efficiency. Andrew Fanara, of U.S. Environmental Protection Agency’s Energy Star program has famously said. “Energy efficiency is the bridge fuel we must build on and must invest in” he stresses “Energy efficiency is the cheapest, cleanest, fastest way to act.”

In part, the administration’s strategy is to use improved energy efficiency as a method of buying time to invest in and explore emerging and clean energy options. With initiatives like the smart power grid gaining traction, the power electronics hardware that makes it all work and its new designs aimed at increasing energy efficiency will be at the core of the plan.

Already, there is huge demand for power efficiency by consumers found an industry survey. And, consumers are willingly paying a premium for electronic hardware that delivers energy efficiency. This trend anticipates a growing number of electronic hardware devices will be utilized, which lowers costs and drives improved energy efficiency. Measured in dollars per watt this high volume of hardware deployment forecasts the efficiency for power electronics may drop to as low as 12 cents per watt by 2013.

The focal point of “smart power” systems and a national smart energy grid has clearly been on the hardware side of the equation. To be successful, in the not to distant future, engineers will also make use of the intelligence provided by software so that the hardware components communicate most effectively to accomplish maximum reduction of power consumption. The know-how exists now for this integrated software, but it is still far from widespread.

Power Profiling is a valuable energy-efficiency tool that granularly identifies the power consumed specifically by HVAC, appliances, networks, lighting etc. and communicates this information to users. A user profile is developed by use of proprietary algorithms that calculate information regarding a structure’s overall usage, and several data points such as the time of day and its energy consumption history.

The purpose of power profiling is to enable users to know exactly what activities or systems are consuming the most power, including how much, and how that consumption is affected by actions they take. Most HVAC and appliances are not yet enabled so numerous hardware metering devices are used throughout the structure, at least an adequate number to demonstrate to the user what the largest power users are and how to limit consumption.

Home Area Networks (HAN) are increasingly communicating with utilities in addition to the traditional media centers and computers. Both utilities and consumer electronics companies are offering and assortment of hardware solutions with methods of pre-programming and remotely controlling home systems such as water usage, heating & cooling, and appliances. With the arrival of “smart” appliances and new wireless network protocols designed specifically for energy-efficiency, many of these hardware solutions communicate to users and utilities over one or more wireless systems.

ZWave for media and home automation

ZigBee chosen by utility companies because of it’s secure protocol, and

EnOcean a European self-powered energy harvesting technology that powers devices without the use of batteries.

Hardware using these wireless protocols can all be controlled from a single point building management system, or a homeowner’s computer. Even though these technologies are still on the leading edge, trends indicates they are very near to wide-scale adoption, enabling buildings to connect to smart grid applications that exponentially increase energy-efficiency.

Advances in alternative energy sources have provided greener ways of producing electricity and the burgeoning energy-efficiency industry is providing a plethora of energy saving hardware devices to help users re-tool . We can reduce energy consumption with these advances and make strides toward energy independence. Consider what T. Boone Pickens says “In additional to putting our security in the hands of potentially unfriendly and unstable foreign nations, we spent $475 billion on foreign oil in 2008 alone. That’s money taken out of our economy and sent to foreign nations, and it will continue to drain the life from our economy for as long as we fail to stop the bleeding.

Projected over the next 10 years the cost will be $10 trillion – it will be the greatest transfer of wealth in the history of mankind.”

“By investing in renewable energy and conservation, we can create millions of new jobs. Developing new alternative energies while utilizing natural gas for transportation and energy generation; securing our economy by reducing our dependence on foreign oil, and keeping more money at home to pay for the whole thing.”

Moving forward with renewables is a must, but it is also a documented fact that this increased capacity will not be enough to meet upcoming demands and provide energy independence. The tremendous strides being made in energy efficiency technologies are to help stem the tide, bridging the gap.

Upgrade Your Building With Led Retrofitting Lights – Add A Innovative Touch And Save Energy

If all the existing high-rise structures and buildings that heighten the skyline of the United States were to be retrofitted with LED Retrofit Lighting, as much as $33 billion can be saved in a single year by the end of 2030. Sounds too far-fetched? Well, it is not too far from the stark reality that the country urgently needs to plan an energy-efficient retrofit to save energy as well as the planet.

Buildings are the largest source of energy efficiency, especially in the United States. LED retrofitting light helps achieve environmental synergy through energy efficient lighting fixtures installed at commercial centers, buildings and homes. Retrofitting buildings with this technology helps to save money on energy bills and reduce global warming.

Within the next twenty years or so, if all buildings in the United States were to be upgraded with LED Retrofit Lighting, the surging demand in lighting electricity can be reduced by as much as 33 percent, generating energy savings of around $265 billion. By using energy efficient lighting for just one-twentieth of all the homes in the United States, the government can definitely, avoid the need for 13 new medium-sized (300MW) power plants every year. At the same time, the total associated greenhouse gas emissions can be lowered by up to 160 million metric tons annually, thus saving our planet from further depletion of natural resources.

The mission behind every strategic initiative towards energy-efficiency is to reduce the emission of harmful carbon dioxide with the help of breakthrough concepts, such as LED Retrofit Lighting, that produces higher levels of energy output using lesser amount of energy. Advancement in technology has made it possible to retrofit any interior or exterior lighting to an LED component with minimal downtime.

However, despite the energy savings and environmental benefits of energy efficiency with LED retrofitting lights, several barriers had earlier prevented homeowners and businesses from retrofitting their buildings. Until a few years ago, affordable financing was one such barrier. Homeowners who were willing to invest in home retrofits and undertake energy efficient improvements were not aware of any financing options that could have been devised keeping the best interest of the community in mind.

The scenario has changed today, thanks to licensed companies in the energy smart industry, who offer innovative retrofit lighting service for homes, commercial complex and other governmental buildings, ensuring guaranteed energy cost savings and unbelievable positive cash flows. These companies specialize in LED Retrofit Lighting and encourage home owners or businesses to upgrade their existing facilities with state-of-the-art energy-efficient lighting with no money paid up-front.

The leading providers of LED retrofitting lights in the United States are well-equipped to retrofit an entire building through a professional turn-key approach, bringing about a neat 75 percent saving in energy bills. In fact, buildings that are powered by LED Retrofit Lighting require less power generation compared to facilities that are powered by other green-power systems. This makes LED Retrofit Lighting a far more economical and technically-feasible energy solution for the modern man. It goes without saying that American homes and buildings present an unprecedented opportunity to save energy and make the world a greener place.

Domestic Energy Assessors Help Homeowners Show the Energy Efficiency of Their Homes When Selling

There is a new breed of professionals who you will get to know about now when you start out to sell your home. They are called Domestic Energy Assessors and are out now in England and Wales performing a brand new service.

The role of the Domestic Energy Assessor is to produce Energy Performance Certificates for inclusion in Home Information Packs. If this is complete news to you then just think of these as being certificates, like those you see on new fridges, which will provide A-G ratings on the energy efficiency of a home, plus advice on how to make further energy savings.

Energy Assessors will use their in-depth knowledge and practical understanding of the thermal performance of your home to judge on the thermal energy efficiency of properties.

This requirement has been introduced by the UK government working on the theory that these assessments of the the capability of all buildings about to be sold will encourage us all to be energy efficient. This will be good for the nation as it will be thoroughly green. It will the idea is, help avoid the need for the energy whether renewable or not.

This type of certificate is required whenever the building is constructed, sold or rented.

In the short term home owners directly, and home buyers indirectly, will need to pay for these Energy Performance Certificates (EPC) and in order to possibly carry out work to improve poorly insulated properties, they will need to pay for general advice to clients on energy efficiency measures.

This is all very good in principle, but the UK government has chosen exactly the wrong time to do this. The credit crunch is hitting the house sales market hard, it is already very difficult to sell properties, and the value of most of them is falling.

The staff that produce Energy Performance Certificates are very experienced in construction technology, building condition surveying and domestic energy assessment and are Degree qualified professionals. They do not come cheap!

Now we do accept that most assessors will not simply stop at inspecting your property, they should also take the time to explain exactly what they are inspecting, how they are going to go about it and gladly answer any questions that you may have. But, most sellers are going to deeply object to being forced by the state to take on this additional burden of cost.

The energy assessor takes measurements to analyse the cost of heating, water and lighting for a house and makes recommendations to improve the energy performance of the house. To me it looks like you the government may think that an assessment is a quick hour in the property and thats it. I doubt they have fully considered the travel time to and from the houses to be assessed, time taken to assess, time to prepare and check the report, input the data, produce the certificate and then charge a fee which includes the professionals insurance, accountant fees, advertising and many other costs – the list goes on and on, after all they will have to make a living like everyone else.

Metal roofs the new frontiers for the energy efficiency of houses

The metal roofing for large buildings that are an ideal solution for both efficiency and maintenance, since they are very resistant and can also enhance the buildings from the aesthetic point of view.

A tangible example of their application has had last December with the inauguration of the Ferrari World Abu Dhabi, the largest spatial structure in the world that is entirely covered by a metallic coating, efficient and aesthetically impressive. Even at the planning and engineering for the construction of the metal roof of the building has required great efforts but we must admit that the performance and end are short of initial expectations.

This is just one example of large-scale applications with high performance that can be obtained by roofing made of various metals, but the fact remains that the principles apply equally to smaller buildings that still need maintenance, but above all high efficiency.
The benefits that can be found in metal roofing are multiple and relate both to the scope of the environmental efficiency of the building by implementing both areas and amortizing the initial investment in no time.

First, it must be emphasized that the metal roof is an investment in real time since it requires no maintenance and does not deform over time, a feature that does not go to affect the ability to modify and relocate the structure. A privilege not just when you think how influential they are in the business budget costs for the maintenance of the structure and its efficient maintenance. The materials are of high quality despite also have a high cost as other types of coverage and thus the maintenance and the change in cost of raw materials and totally accessible. Also in front regarding the benefits of this coverage must be remembered that these are immune from the deterioration that instead affects roofs made of different material such as mold, bacteria, decomposition, and if placed properly sealed and allow a greater resistance to weather very well aggressive as wind, hail and ice, and their design allows you to easily throw them out or snow accumulations of leaves and other materials. Many others are also the absolute advantage as compared to crack and leak tightness and perfect seclusion from the outside.

Moving on, however, their application must be stressed that, thanks to the evolution that these covers have had over time, and thanks to the efforts of designers and architects who have tested it with hand applications and possible variants allowing to develop products that can be applied not only to industrial buildings and corporate offices (so far privileged places for the application of these types of coverage) but also to private homes that go well with contemporary lines and take energy efficiency and autonomy, unique and advanced to the ecological level. E ‘to stress that this type of coverage also allows for easy application of photovoltaic panels and other installations for the production of renewable energy, making it even easier to install these plants in a certain period after completion of the house.
