Air conditioners are some of the home appliances that homeowners need to keep their homes comfortable. However, they are also some of the home appliances that raise the energy bills in your home. Buying an energy efficient air conditioning unit is therefore necessary if you want to keep your energy bills at a manageable level and still keep your home cooled. The following is a short buying guide for buying an air conditioner.
First, decide whether a ducted air conditioning unit or a split wall hung air conditioner best suits your home. Ducted air conditioners best suit large houses with multiple rooms. Split systems are best suited for small rooms.
Second, start by looking at your home before going shopping. This will allow you decide what sizing of the air conditioner is required for your home. The sizing of the air conditioning unit doesnt mean its physical size. Rather, it means its capacity in British Thermal Units (BTU). To determine the air conditioner size you will need for your home, there are a number of features to look at. The most basic feature is the size of the rooms. In addition to this; look at the insulation in the rooms, window orientation, number of occupants in each room, artificial lighting and, appliances and furniture in the room among other features.
Third, look at additional components in each air conditioner and how useful they can be in making the air conditioning unit more energy efficient. For example, an air conditioner with a programmable thermostat will enable you set the unit to switch on and off at predetermined times. Most air conditioners with additional components will be on the high end. The best way to determine whether they are worth investing in or not is looking at what value they are adding in terms of reducing the energy consumption of the air conditioning unit.
Fourth, look for alternative air conditioners. Common air conditioners are plugged onto the electricity outlets in the house. Today, there are green air conditioners which are solar powered. These will enable you save on up to half the energy consumption in your home.
Fifth, look at the manufacturers warranties placed on the air conditioners. Like other electrical appliances, an air conditioning unit is prone to ear and tear. The warranty on the parts guarantees that the manufacturer will replace or repair worn out parts within the warranty period. Since the average air conditioner will last between 5 and 20 years, its best to look for an air conditioner with a longer warranty period to ensure that worn out and broken parts are replaced on time ensuring efficiency.
Finally, look at the Seasonal Energy Efficiency Ratio value of the air conditioning unit. A higher value indicates that the air conditioning unit is energy efficient.
Presently the organizations have been aiming at efficient ways and procedures to attain more with less, reducing IT expenses and even minimize the incidental costs associated with data center growth and expansion. In today’s competitive market scenario data center managers need to focus on establishing effective operating environments to support the life of the existing data centers. There are numerous ways in which companies can attain data center efficiency and is inclusive of setting up a cold aisle containment system, efficient utilization of outside air and maximize compute densities. The main component however is to maintain a comprehensive metric system to evaluate how efficient is the data center and what are the efficiency enhancements that have been created.
How to estimate data center energy efficiency?
PUE, i.e. power usage effectiveness is one of the most common metrics used for calculating data center energy efficiency. It is calculated by taking into account the overall power consumption of the data center facility and then dividing it by the power consumed by the devices. The ratio that you arrive at is the effective power overhead for a single IT unit load. Most data center managers today are expected to find out ways to reduce the PUE so that the data centers can find a better way to expand.
A better way to expand is by partnering with a data center solution provider that will free organizations from all the worries of establishing and maintaining critical mission IT architecture. Advanced data center today fulfill all the needs for cloud computing services, shared hosting services, dedicated hosting services, collocation services and other security and firewall solutions. In addition to that, the organizations remain secure and well supported 24 x 7 with advanced facilities and industry leading SLAS.
Furthermore, these solution providers offer you the various ways to bring about a change and enhancement in data center energy efficiency. Two essential ways are:-
Minimizing the power that is used for the support infrastructure
Minimizing losses within the power system
By following the above mentioned ways you can ensure greater power entering the data center thereby improving its energy efficiency and reducing the PUE. At the same time, it is critical for an organization to bring down the power system losses and the power utilized for supporting infrastructure. Concurrently, it is also apparent that the mass power consumption in the data center gets transferred to the IT load. If an organization can bring down the IT load then it can naturally reduce the overall power required in the data center.
With the 2012 Ontario Building Code deadline calling for homes to be 35% more energy efficient than homes that are built today, new home builders could be faced with the additional cost of installing higher end heating and cooling systems. And new home buyers may be looking at more sophisticated heating and cooling systems that require a higher level of expertise in maintenance and repairs. A practical alternative for both builders and new homebuyers is a bundled rental package that includes a water heater, along with a furnace, air conditioner, air handler or drain water heat recovery system. Since 2003, Reliance Home Comfort has offered bundled rental packages (rental furnaces, air conditioners, water heater and air handler combo systems, indoor air quality products and more) to the existing residential market, and the option has caught on with a growing number of homebuilders. In 2009, over 4,500 homeowners chose to rent their furnace, air conditioner, or system from Reliance. And for the past two years, Reliance Home Comfort has been offering its Comfort Value Bundle Program to the new homes market as well. Builders can choose from three set packages or they can have one that is custom, with any combination of heating and cooling products. One of the more popular bundles is a water heater and air handler rental. Other possible combinations include a water heater with air conditioner, or with air handler.
Reliance provides rental customers with complete peace of mind. We take the risk out of products and services that are essential to our customers lives. And we make it easy and affordable for families to stay comfortable all year long, says Neil Martin, marketing manager for Reliance Home Comfort.
Typically new homebuyers expect the furnace to come with their home and the idea of renting your furnace is a fairly new option. Our Comfort Value Bundle program is becoming a popular choice with customers who value the ability to heat and cool a home for maximum comfort and energy efficiency at the lowest cost.
Currently, 96% of Ontario homeowners rent their water heaters. The Comfort Value Bundle Program
is a natural extension of this approach and Reliance Home Comfort is working to raise awareness
about this option amongst GTA homebuilders.
Builders save on capital costs and, depending on the energy efficiency of home comfort products, homeowners can save up to $35 per month on their energy bills.
Rental rates for a high-efficiency gas furnace and an Energy Star water heater is approximately $50 per month probably less than your cable bill, says Larry Brydon, senior account executive for Reliance Home Comfort.
We take the worry out of replacing heating and cooling equipment by paying the capital cost and by providing guaranteed service 24/7/365. And if you sell your home, the equipment is carried on to the
next homeowner, who assumes the rental agreement.
Reliance Home Comforts large network of licensed service technicians are trained to maintain and
repair a variety of products including GSW water heaters, Rinnai tankless water heaters, Venmar heat
recovery ventilators, Goodman furnaces and air conditioners and Power-Pipe drain water heat recovery
systems. Homeowners have live phone support in the event of a breakdown, as well as 100% coverage
on all parts and labour. One of such licensed contractors of Reliance is ACfurnaceGTA.ca (division of Air Efficiency Corp.) doing the quality installation of all Reliance HVAC equipment.
Were seeing a lot of interest now, especially since the Energy Star and LEED programs in the new homes market, Brydon says. Energy Star for New Homes is a proven program aimed at building homes that consume less energy, on average about 25% less than a home built to minimum Ontario Building Code standards.
The LEED Canada for Homes program goes beyond Energy Star for New Homes by pushing energy efficiency even further, and offering higher standards for clean air and less water use.
There is a big uptake on products offered as part of Reliances Comfort Value Bundle Program with first-time purchasers who are young and eco savvy, as well as retirees, who are socially responsible and are concerned about ongoing operating costs, says Brydon.
The business case for energy efficiency is a powerful one. At the end of 2010, the Carbon Trust reported that the average return on investment of energy-efficiency projects carried out in commercial premises is 48%. Increasingly, it is becoming clear that to invest in sustainability is to save money.
But while the UK government is supporting carbon reduction by introducing grants and green initiatives, these have done little more than skew people’s perception of what represents an energy saving. With heavy focus applied to insulation and heating, cooling strategies have been left rather more out in the cold.
The hot topic
The government’s Renewable Heat Incentive (RHI) was announced in March 2011 to drastically alter the way heat is generated and used in buildings and homes. Britain’s largest energy users are required by the CRC Energy Efficiency Scheme to start lowering carbon emissions so will naturally be enticed by such offers. But incentives like the RHI fail to acknowledge that when a commercial building is designed, the crowds of people and electrical appliances that then occupy it are not taken into account.
Human bodies and devices such as computers, printers, coffee makers, toasters and refrigerators generate an exceptional amount of heat and cause room temperatures to dramatically increase. So, instead of heating, most commercial buildings need to bring temperatures down in order to maintain a comfortable environment and maintain staff productivity.
Office cooling, namely air conditioning, represents a huge energy burden, and can increase a building’s emissions by 100%, according to Carbon Trust research. So, to use it on a daily basis yet take a grant to invest in heating and insulation is a notion most people would surely see as perverse.
The reality of air conditioning is that, despite its widespread use, the energy it consumes often goes to waste. Realistically, without tackling this problem it is unlikely than any commercial building will be able to create a truly energy-efficient environment, no matter how much government grant money it is awarded.
Here comes the sun
As we all know, when the sun comes out in the UK, it is met with something resembling blind panic. Whether in the heights of summer or the depths of winter, sunshine causes heat to build up through unprotected glass windows. These windows then get thrown open to create a through draft, or in colder months, blinds will be snapped shut to block out the sun’s glare, meaning that lights have to be switched on. Either way, this behaviour ends up negating the effect of air conditioning, causing wildly fluctuating internal temperatures and eating up a large, unnecessary supply of heat and energy.
Such widespread and basic energy wastage should not be allowed to continue. Maintaining stable internal temperatures requires more than efficient heating and insulation; businesses need a cooling solution that minimises air conditioning, allows natural light to enter the building and helps to block out heat, rather than trap it within the building. One of the most simple and most cost-effective solutions that can deliver all of these benefits is one you may not have heard of: solar-control window film.
By rejecting up to 82% of solar energy, window film can reduce internal temperatures by up to ten degrees. This stops air conditioning units from being maxed out during sunny spells, meaning that internal temperatures are kept stable and extreme peaks in energy usage are reduced.
Cooling systems can therefore be run more efficiently and inexpensively, reducing a building’s cooling load by 30%, or roughly 5% of the energy bill. If window film were taken into consideration during the design stages of a new building, savings would be greater still as businesses would reduce cooling requirements from the outset; using smaller, cheaper air conditioning units that are easier to install and maintain. In plain English, this could mean thousands of pounds in savings to many UK firms.
Love in a cold climate
With budgets being squeezed and such significant carbon reductions to be made, the heat is on for UK businesses to find meaningful ways to lower emissions. It is the responsibility of our government to steer them in the right direction. Improved insulation and heating is, without doubt, an effective means of preventing energy waste, but without considering the likely effects of over-heating, businesses are in danger of missing the bigger picture.
While most UK businesses will currently look to insulation as their first port of call for energy savings, more vocal support for solutions such as window film by government schemes and incentives, would show these companies that such measures are just the tip of the iceberg.
Although efficiency has always been relatively defined by every kinds of enterprise. For instance, there would be companies which qualify productivity as a measure for asset efficiency. Although there have been plenty of reviews on asset and appliance energy consumption, there had been little on energy efficiency per se.
While companies are getting busy plotting their action plan, they are also giving attention to the fact that energy efficiency is of utmost importance. Measured against the pervasive threat of climate change, society dictates that business interests are inferior.
Our society presses on having each business take accountability for its own emissions and justification of such. This is an emerging threat to the viability of organizations and will now require them to adopt enterprise carbon and energy management systems as they not only begin to understand their actual positions but get ready to answer to society and legislators.
A common organization operates through the interaction of its assets. Each asset is responsible for the consumption of energy and the consequent emission of greenhouse gases. Emissions which are related to energy consumption are one of the largest contributors to climate change and other environmental degradation which should be stopped if needed.
While we are not yet at a position where the preceding statement can be viewed as black and white, we are certainly heading in that direction. For an organization to exist, let alone prosper in the future it must justify its possession of each asset and be sure that the asset is performing to ultimate efficiency. Enterprise carbon and energy management systems enable such tracking and provide a clear correlation between energy use and emissions spent.
We are very likely to see legislation. which requires consent for using energy and carbon emissions, enclosed within market forces. In this highly competitive and market-based economy, involved parties need to have openness and encourage transparency in conducting business to be satisfactorily compliant. Again, in this world a healthy balance sheet owes a lot to the performance of individual and sometimes lowly asset groups and thus the significance of asset performance tracking may not be understated.
There is a clear link between asset energy efficiency and carbon emissions and as carbon becomes a protected, trackable and tradable commodity, organizations must enable the link.
Enterprise carbon and energy management systems focus on energy efficiency and performance. Software providers such as Verisae have already amassed experience by providing such an approach to a number of retail organizations worldwide. Forward-thinking companies know and understand that although legislation would not be targeting enterprises at the moment yet, they also understand the importance of adamantly acquiring the most effective information possible.
While political debate and agendas can often slow the advance of legislation, societal opinion appears to be consolidating and organizations that are slow to take the initiative and adopt a clear path toward sustainability may indeed be very shortsighted.
Modern technology has given us a plethora of things to conserve energy and better manage our environment. One of the critical items on the list is the energy efficiency energy management system manufactured by MHT Lighting. This is an aspect of our world that thousands of individuals (especially investors) are looking into more carefully. Apparently, there is a promising future for the use of energy.
In general, there are a number of ways to manage energy. For example, its important to pay close attention to what will reduce expenses long-term. Most of us havent even given the idea a second thought, let alone done any research into what this phenomenon can do to benefit the economy or the environment. For this reason, it is easy to be misled due to lack of knowledge; and its hard to appreciate something we dont fully understand.
There is a wide variety of devices which will ultimately help conserve energy. The use of systems and products for the management of energy is highly effective and beneficial. For example, electric bills may be reduced by simply using energy efficient light bulbs and appliances. These devices are the ultimate energy-savers, and are highly recommended and should be given consideration by consumers and investors alike.
Many consumers prefer MHT products with hybrid energy efficiency. Consequently, its imperative to give careful attention to specific products for various needs. MHT products are ranked among the best due to extended warranties, which is an undeniable bonus. Thousands of people once doubted the stability of these products; however, solid foundations have alleviated the need for doubt or concern.
One of the most interesting MHT products is the SP1000. This piece of high-tech equipment reportedly brings efficiency to a minimum of 95 percent and reduces on-demand charges (proactively) by 60 percent. These effects create guaranteed, measurable savings on energy use. In addition, this handy equipment stores up to one year of important information for auditing purposes. The return on investment is usually 1-2 years; however, the savings are immense and certainly worth the time and investment!
In short, this device will avoid over-working valuable equipment and saves consumers their hard-earned dollars on the consumption of power. This is a tool which is software driven and offers real-time reporting and monitoring. One restaurant reported an initial energy bill of 15 thousand per month. Once the SP1000 was installed, the estimated savings was $1,800 each month! Thats a 12 percent decrease!
Apparently, there is a promising future for this type of hybrid energy. Lighting manufacturers will most likely be keeping an eye on this aspect of efficiency (for both energy and their pocket books). Many energy solutions in America are now founded on this process, implying that this sector of business is only destined to grow in leaps and bounds. Even more fantastic ideas and results are bound to branch out over the next decade. It would do the consumer well to keep an eye on this industry.
In todays economy, organizations, consumers and companies will expect more from each device or product purchased. The demand for excellent quality has reached an all-time high. America demands companies who will back their products for a very long time.
In light of the current economic conditions that the country is facing right now, several programs have been placed in the priority list that will address some of the most critical issues faced by Americans right now. One such issue is on the use and consumption of electricity, wherein a national program was set into motion to generate interest among consumers in various states to participate in energy efficiency programs starting with their own homes.
Texas has been at the forefront of the nationwide energy efficiency drive with residents given the power to select their energy options in a bid to reduce consumption of Texas electricity. Such programs include rebates from their property taxes that eventually pay for the energy efficiency improvements done in their individual homes. Such improvements can include the installation of solar panels or improving a homes insulation system and optimize use of electricity.
These incentive programs are aimed at reducing the up-front costs that homeowners will incur as they set out and initiate energy efficiency improvements in their homes and improve their use of Texas electricity. Not only that, energy efficiency improvements will enable homeowners to gain considerable savings from their electricity bills as well as a focus on alternative energy resources that will eventually pave the way for the availability of really cheap electricity for all consumers to enjoy.
Energy efficiency programs were officially initiated when the 75th Texas Legislature promulgated into law the requirement for meeting specific energy efficiency goals that the electric TDUs or Texas Transmission and Distribution Utilities would have to meet. The procedures required to meet these goals were outlined in the Energy Efficiency Rule provided by the Public Utility Commission of Texas.
The rule specifies that TDUs should offer energy efficiency programs to consumers within their respective electricity distribution territories. Such programs include installation or home improvements designed to increase a homes overall energy efficiency such proper insulation, use of high efficiency lighting fixtures and the installation of solar energy systems among other. These programs are extended not only to residential communities but also to schools, local governments and businesses in order to reduce their operating costs and save Texas electricity.
These home improvements however, will be installed or performed not by the TDUs themselves but will be coursed through third-party providers or what is more commonly called now as project sponsors. These providers include contractors and installers for insulation, lighting, and air conditioning. Project sponsors also include the retail electric providers and other energy efficiency companies.
What the Texas Consumer Can Apply Now
There are various energy efficiency incentive programs initiated by the local distribution utilities in the various towns and cities in Texas, each of whom were mandated to meet energy efficiency goals. These incentive programs come in the form of Standard Offer Programs (SOP), with payments based on the energy efficiency performance achieved. Participation in these SOPs varies depending on the type of program initiated. These programs include:
Residential and Small Commercial Programs these are geared towards providing incentives for energy efficiency improvements that are installed to reduce electricity consumption and peak demand
Commercial Programs Has a specific minimum demand requirement for eligibility and provides incentives for energy efficiency installations and measures that will reduce peak demand and increase Texas electricity savings
Low Income Programs Energy efficiency programs that are targeted towards households having annual incomes that are below or at 200% of the federal poverty guideline.
Load Management Programs These are designed to encourage efficient control of electrical loads such as shifting of electric loads from peak-demand hours to off-peak periods.
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.
With energy prices seeming to be constantly on the rise, homeowners are always on the lookout for ways of saving money through lower energy bills. Fortunately, one of the best ways of cutting energy is by taking steps to make a Baxi boiler more energy efficient. While Baxi already produces some of the most energy efficient boilers on the market, homeowners can always take further steps to help improve the environment and save them money on their next energy bill. Energy saving tips can range from the simple, like fitting pipes with insulation, to the extreme, like getting a brand new boiler installed. This article will look at just a few of the measures homeowners can take to make their boiler systems more energy efficient and thus cut their energy bills at the end of the month.
Use Room Thermostats
Installing a room thermostat is a great way of being able to control the temperature in individual rooms. Having better control over a homes temperature will go a long way in cutting down on wasted energy. Room thermostats can save consumers about 70 a year and they will go a long way towards protecting the environment. Once the room thermostats are installed, homeowners should turn down the temperature until it is warm enough to still be comfortable. Turning down the temperature just one degree can make a world of difference, and could save families 65 a year.
Hot Water Cylinder
Similarly, most UK families keep the temperature of their hot water cylinders up too high, which is not only wasting energy, but costing consumers more in higher energy bills. The ideal temperature for a hot water cylinder is 60 degrees Celsius, which is more than hot enough to still be comfortable for most homeowners. Water that is kept any hotter than this is not only wasteful, but it runs the risk of scalding human skin it comes into contact with. To make the hot water cylinder even more efficient, the main tank should have a tank jacket wrapped around it. Additionally, any pipes around the tank that are exposed should be insulated. Insulation will not only improve energy efficiency, it will also help the system last longer and perform better. The total cost for the tank jacket and insulation should cost no more than 30, while it could save families 60 a year in lower energy bills.
While all of the above recommendations are good and cheap to follow, by far the best thing people can do in order to cut their energy bills and improve their homes efficiency is to invest in a new energy efficient boiler. It is usually fairly easy to determine if a boiler is in need of replacing. Older boilers usually have a pilot light which burns continuously. The pilot light itself is not only wasteful, but these older boilers also have much lower efficiency ratings overall. Newer boilers have pilot lights which light automatically whenever the boiler is put into use, meaning that less gas is wasted when it is not actually being used by the homes occupants. In fact, the newer energy efficient models have an efficiency rating of up to 90 per cent. From a consumer standpoint, this increased efficiency could translate into an annual savings of over 300, not to mention a household that is much gentler on the environment. Of course, the main disadvantage of getting a new boiler installed is that they are very expensive, often running into the thousands of pounds. However, compared to the savings possible, a new boiler may be worth the investment. Furthermore, grants and trusts have been set up that can help the most disadvantaged improve their homes energy efficiency thus saving them money.
Many consumers are seeking to improve their households energy efficiency for a variety of reasons, ranging from wanting to save money on energy bills to trying to do some good for the planet. One of the best ways of cutting down on carbon emissions is by improving a houses current Baxi boiler system. By taking the measures listed above, whether that means buying a new energy efficient boiler or simply reducing a homes temperature by just one degree, homeowners will be doing their part to make the planet a little greener and their utility bills a little lighter.
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.
