Western Australia Classrooms To Be Built Without Air Conditioning

Wednesday, March 31st, 2010, by Richard Salmon

Despite Western Australia’s status as one of Australia’s most consistently hot geographical areas, the State’s education board has decided to limit the number of air conditioners installed in new school buildings and existing classrooms. The policy is in line with other state cost-saving measures, including reduced school resources and completing more schools, rather than upgrading existing classrooms.

Temperatures in the state vary due to its North-South length, but can occasionally reach well above 40°C. The hottest recorded temperature in Western Australia is 50.5°C, measured in February 1998 in the state’s tropical northern section. While state capital Perth enjoys year-round moderate weather, classrooms in the state’s tropical and arid desert areas can often experience extreme temperatures.

Yet a large number of classes are still lacking adequate an air conditioning service. While the state’s ultra-hot Kimberley region has air conditioners fitted in all school buildings, classrooms located in other towns experiencing year-round heat are currently unfitted for air conditioning units. Aiming to reduce expenses, schools are required to use ceiling fans and open windows for cooling.

Despite the region-based air conditioning system, a number of nagging issues remain. Schools built along regional lines are often left without air conditioning systems, despite sharing climate zones with other ‘in region’ schools. While many schools are appealing to parents and potential sponsors for financial support, it appears that air conditioning may not be on the curriculum, even for some of Australia’s hottest schools.

How Much Energy Does an Air Conditioner Use?

Tuesday, March 30th, 2010, by Richard Salmon

Malaysia’s ‘cheapest’ hotel – the Air Asia branded ‘Tune Hotels’ – offer an interesting pricing model. Rooms are incredibly inexpensive – often very close to free – and offer minimal comforts. Air conditioning, excess electricity, and other ‘luxuries’ are charged on their own, with visitors presented a bill upon checkout.

The two-tier pricing makes it seem as if air conditioning is a taxing extra expense, costing hotels thousands of dollars monthly. In reality, an air conditioning service is relatively cost-effective, and certainly not the power guzzler that many people believe it to be.

American air conditioning company AeroSys were one of several to learn that air conditioning must be cheap, after their units were withdrawn from the market due to excess electricity usage. Despite the cost-inflating behaviour of ageing air conditioning units, newer air conditioners are required to maintain a certain power level by law.

This leaves the actual cost of air conditioning at very low rates. When used correctly, an effective air conditioner can cool an entire home for less than two pounds daily. Energy conservation advocates claim that expensive power bills are often the result of air conditioning misuse, not the unit itself.

Small changes such as fan strength and room temperature can greatly influence electricity usage, with high-power fans and extreme temperatures drawing more power than moderate use. The message for consumers is clear – air conditioning isn’t expensive, except when used ineffectively. With the right strategy, air conditioning can be a cooling method no more expensive than the average ceiling fan.

UK Due For a Heatwave, Weather Service Claims

Monday, March 29th, 2010, by Richard Salmon

After 2009’s wet summer and major winter storms, Britain is overdue for a heatwave. Climate prediction group Positive Weather Solutions, who correctly predicted last year’s weather conditions, are warning Britons that summer temperatures may exceed 38°C. Despite having just five employees, the weather group has correctly predicted and identified major weather patterns and unusual events, such as 2009’s “big freeze” winter.

Positive Weather Solutions claim that June and July’s weather patterns will mirror last year – large amounts of rain and relatively limited sunshine. Where they’ll differ, the organization believes, is in August. PWS are predicting record levels of sunshine and heat in 2010’s August, possibly even to the point of a new British record temperature.

The warmest summer on record left an all-time high of 38.5°C – a target that’s rarely been approached since it was recorded in 2003. Analysts suggest that this year could be the time that Britain’s weather becomes slightly warmer, with all-round temperature averages predicted to stay at approximately 18°C.

Whether Britain’s weather fantasies come true or not is certainly up for debate. What’s not, however, is the amount of enthusiasm and caution that Britons are showing for the predicted heat. In response to the prediction, many are planning an air conditioned summer – locked indoors and forced out of the heat.

Our advice: enjoy the sunshine. While Britain’s temperatures may end up brushing on uncomfortable, there’s always a way to avoid discomfort – spend mornings enjoying moderate sun, and escape to comfortable environments cooled by an air conditioning service during peak sunlight hours.

The World’s 10 Hottest Major Cities

Monday, March 29th, 2010, by Richard Salmon

Hot weather is the enemy of the productive. What could have been a great day of work outdoors turns into an all-out fight to avoid sunlight. We sprint indoors, crank the air conditioning up to patently dangerous levels, and do everything possible to ensure that the endless outdoor heat doesn’t manage to reach the living room.

Still, there are places on earth where extreme heat isn’t just a one-off occurrence, but a regular event. From tropical megacities to arid desert civilizations, we’re tracked down ten major cities that receive extreme heat on a regular basis. If you’re not a fan of the sun, note these ten destinations down on your ‘do-not-visit’ travel list.

1. Jazan City, Saudi Arabia

Jazan City is a port on Saudi Arabai’s Red Sea coast, and unlike many of the other cities we’ve featured, it’s populated by less than 2 million people. The ultra-hot city may not boast the most ridiculous summer temperatures, but its year-round heat makes it one of the most consistently warm in the world.

2. Bangkok, Thailand

While Bangkok doesn’t experience the world’s most extreme summer temperatures, it is the world’s hottest city when it comes to year-round intense heat. Temperatures in the Thai capital routinely rise above 40C during the day, with night-time temperatures hovering at similar levels.

Bangkok’s notorious smog is also a problem for those with heat aversion. The megacity’s well-known air pollution traps hot air within the city center, causing daytime humidity and heat that catches many tourists off guard.

3. Las Vegas, Nevada

Situated in the middle of Nevada’s arid desert, Las Vegas experiences temperature extremes like no other US city. Daytime summer temperatures often reach 40°C and occasionally even higher, with the crisp desert heat proving a problem for unprepared tourists and week-long bender participants.

While not the hottest city in North America, Las Vegas is located very close to the hottest location in the entire Western Hemisphere: California’s Death Valley. In 1911, temperature gauges at the park recorded a daytime high of 134°F (56.7C) – just one degree short of the world record.

4. Hong Kong, China

Hong Kong isn’t the world’s hottest city. As a matter of fact, it wouldn’t even break the top ten in a list of the world’s hottest points. However, when combined with the city’s legendary humidity, this sauna-style tropical city is one of the world’s most extreme and uncomfortable, especially during its ultra-moist wet season.

Just how bad is it? Bad enough for Hong Kong’s residents to devise specific paths to every possible destination, each of which is designed to follow through as many air conditioned shopping malls as possible. While daytime temperatures tend to fall around 30°C, this ultra-humid Chinese megacity feels more like a steam room than an international metropolis.

5. Mexicali, Mexico

Baja California is home to some truly extreme temperatures, and Mexicali is the city at the center of it all. This metropolis of over one million residents hits 40°C on many summer days, with ultra-hot periods boosting temperatures well above what most residents would consider comfortable.

Due to its inland desert-style location, Mexicali attracts some of the hottest temperatures recorded in Baja California. While Los Angeles, San Diego, and other major population centers along North America’s west coast enjoy year-round warmth, Mexicali’s slight inland placement keeps it free of the Pacific Ocean’s regulated temperature.

6. Melbourne, Australia

Melbourne is a slight climate anomaly, largely due to its unusual placement between Australia’s cool Southern Ocean coast and the country’s world famous outback areas. While Melbourne doesn’t experience the year-round heat of Darwin, Singapore, or Bangkok, it does experience some summer temperatures that would make even the most hardened outback resident blush.

For example, the February 2009 heatwave saw Melbourne’s temperature exceed 46.4°C – an Australian state capital record. Most months don’t result in a scramble for the air conditioners, as Melbourne’s year-round average temperature is just 19.8°C – a mere 68°F.

7. Kuala Lumpur, Malaysia

Kuala Lumpur is known for its amazing skyline, huge dining variety, great shopping, and multi-cultural nature. Unfortunately, many visitors remember it for only one thing: the sweltering year-round heat and humidity. Thanks to Kuala Lumpur’s placement almost directly on the equator, the city experiences some of the most intense heat and humidity that Earth has to offer.

While maximum temperatures have never exceeded 37°C, Kuala Lumpur’s 30°C median temperature says a lot about the city. If you’re planning a trip to Malaysia’s large and interesting capital, it might be best to carry a little less clothing than you planned for.

8. Phoenix, Arizona

Phoenix is the United States’ fifth largest city, and by far its hottest, according to information put out by the US Weather Channel. Situated on the edge of Arizona’s Sonoran Desert, temperatures in the city exceed 40°C during the summer, with daytime heat driving many of the city’s residents out of the sun and into their air conditioned homes and offices.

9. Athens, Greece

While Athens was once known for its intense pollution, it’s emerged as a European leader in another category: extreme heat. The Greek capital experiences summertime temperatures in excess of 40°C, and has laid claim to Europe’s all-time temperature record with a July recording of 48°C.

Adding to the problem is the city’s smog. While improved from its 1970s peak, Athens is still shrouded in grey mist on occasion, reducing the city’s ability to moderate temperatures effectively.

10. Cairo, Egypt

Source: http://www.flickr.com/photos/garyjd/73638843/

Situated on the banks of the famous Nile River, Cairo is the largest city in Africa and one of the hottest major cities in the world. Due to its placement alongside a major river, Cairo receives both the heat of the major Arabian deserts and the humidity of the Nile River Delta. That means a combination of intense desert heat, often in excess of 40°C, and extreme humidity is on the cards for Cairo’s summertime residents.

Toyota’s New Solar Air Conditioned Prius

Friday, March 26th, 2010, by Richard Salmon

Fans of green technology and cool air are in for a surprise when they look inside Toyota’s new 2010 Prius. The new hybrid car comes equipped with a full solar power panel for its air conditioning and in-car entertainment system. In a move towards total green energy, Toyota have stripped away the standard power-hungry air conditioner and replaced it with one that’s closer to a solar cooling system than the gas-sucking system most people know.

It’s said that in most cars, just 15% of used gasoline makes it to the wheels. This alarming statistic is, in most cases, quite true. Air conditioning services, entertainment systems, engine control computers and lights each require a large amount of energy, most of which is generated through burning gasoline. 2010 Toyota Prius by alex4981.

Toyota certainly aren’t the first company to embrace solar air conditioning, although they are the first auto manufacturer to use the technology. A number of office buildings have made use of solar energy for their cool air systems, including the American Apparel factory and management building in Los Angeles.

‘Green conscience’ affects thousands of consumers annually, a spending trend backed up by strong sales of hybrid cars and power-saving equipment. Home air conditioners have been optimized to the point of impressive energy efficiency, however many automobile systems still lag behind in energy usage. While Toyota’s solution certainly doesn’t cut down on all energy usage, it’s a clear step in the right direction.

3 Ways to Keep Your Car Cool Without Air Conditioning

Wednesday, March 24th, 2010, by Richard Salmon

Every driver has experienced the ‘car oven’ phenomenon. You set off to work on a warm day only to realise that your low-end car lacks air conditioning. Next time you find yourself caught out in an ageing or low-cost automobile, don’t despair. Now, off course we’re total buffs when it comes to air conditioning but although it’s mightily important on a grand scale, it isn’t actually the be-all and end-all. These three tactics can help you keep the car cool, crisp, and comfortable for your commute or long distance journey.

1. Crack your windows, and crank up the fan Inside the New Car by Chris Campbell.

Fan systems are most effective when combined with a source of fresh, cool air. For most car owners, that means a slightly opened window. Don’t open it all the way if it’s warm outside – just crack the window and let a small amount of fresh air enter the car.

2. Store ice in the car

Unfortunately, it’s not quite as easy as popping down to the supermarket and dumping ice cubes in the car. By storing a container full of ice next to your car’s ventilation system, you’ll be able to cool and humidify the air without worrying about excess gas usage. This old-fashioned air conditioning method was popular in Arizona in the mid 20th century.

3. Apply window tints

Tinted windows don’t actively cool your car, but they do cut down on the amount of sunlight that can enter. By decreasing the transparency of your windows, you’ll let less light enter the car and quickly lower the overall temperature. Be careful – some country’s ban tinted windows, or apply limits to the transparency level of the glass.

And no air conditioning maintenance costs going forward…

Lofts and Attics: The Forgotten Air Conditioning Areas

Tuesday, March 23rd, 2010, by Richard Salmon

We all remember high school physics classes, right? Warm air rises, and just like many other scientific truths conveniently ignored by homeowners, this one comes with some real-life added effects: an annoyingly toasty temperature in your loft.

A growing number of UK residents are enjoying the warm air on offer in summer by converting their otherwise stuffy attics into full-scale loft living rooms and bedrooms. While most stick to the basic conversions and additions – a small sofa, TV set, or fold-out bed – a range of UK do-it-yourself fans are investing a lot more time, and some serious money, into their lofts. Loft by someToast.

Of course, there’s one part of renovating a loft that’s often ignored: the temperature. Even in the UK’s crisp climate, warm air tends to rise upwards through the house towards the loft or attic space. In homes with insulation, the air difference can be quite noticeable, particularly when the loft itself is only used as a relaxation or living area.

There’s a clear solution, though. Air conditioning service units are available for a range of spaces and room sizes, and loft owners are often let off the hook when it comes to price. With small attic rooms and living spaces, the cost of a full-power air conditioner can be remarkably low.

So save yourself from sweating this summer with an air conditioning unit for the new loft living space. Inexpensive, quiet, and ultra-convenient, an air conditioner is the perfect addition to any stylish loft living space.

Air Conditioning as a Design Element

Friday, March 19th, 2010, by Richard Salmon

For most building developers and architects, air conditioning is more of a design hindrance than a blessing. Thousands of air conditioning units can mark the sides of a building, turning potentially beautiful condominium towers and office buildings into Lego brick constructions, all featuring boring beige boxes on every floor and balcony.

However, for some designers, air conditioning has become a powerful, unique, and visually appealing design element – providing an effective and also aesthetic air conditioning service. These two examples of innovative air conditioning design prove that there is design value in an air conditioning unit, no matter how beige, boxy, and uninspiring it is.

1. The Lloyds Building, London New Lloyds building again by Elsie esq..

The Lloyds Building is an interesting piece of London’s architectural history, and one that’s drawn a lot of praise (and a lot of criticism) across its life. What makes the Lloyds Building so unique is its use of air conditioning ducts, stairs, and other building utilities. Once reserved for the inside of a building, the Lloyds Building uses them as a design element on the outside.

Interesting or just plain ugly? Most architectural critics are fans, citing the building’s innovative use of air conditioning as a major feature of London’s city skyline.

2. The HSBC Headquarters, Hong Kong

Hong Kong June 2009 by Remko Tanis.Hong Kong is the skyscraper capital of the world, and the giant HSBC Building certainly keeps up with its image. Constructed, like the Lloyds Building, with the air conditioning ducts on the outside, this innovative high-tech structure uses air conditioning as a major design feature. Love it or hate it, this cool construction method has drawn praise from architects and energy efficiency experts alike.

The World’s Hottest Cities – 3 Destinations Where Air Conditioning is a Must

Thursday, March 18th, 2010, by Richard Salmon

Need to travel to somewhere hot? If the winter cold spell is getting you down, a quick trip to one of these tropical hot-spots could be just what’s needed. However, you’d better be comfortable with an air conditioner – with highs of almost 40 degrees Celsius, a holiday in one of these destinations could get painful quickly.

Before you step off the plane into any of these three cities, make absolutely sure your hotel’s got a good air conditioning service:

1. Bangkok, Thailand Bangkok Skyline by Mobile First.

The Thai capital may not be the hottest place on earth, but it does have the highest average annual temperature. With highs well into the high 30s coupled with the occasional 40 degree day, this tropical megalopolis doesn’t quite touch deadly heat, but it certainly does verge on uncomfortable.

2. Jizan, Saudi Arabia

Jizan isn’t the hottest place on earth (an honour that goes to California’s Death Valley) but it is one of the most consistently hot. This small city in western Saudi Arabia is closer to tropical than desert steppe, although it does experience the occasional dry month.

3. Wyndham, Australia

Wyndham certainly isn’t the place to go for relaxing summer temperatures. Despite being situated in tropical Western Australia, the small town rarely experiences temperatures below 30 degrees. Highs touch on 40 quite regularly, making Wyndham a pretty nasty place for cool weather fans.

3 Common Air Conditioning Mistakes

Wednesday, March 17th, 2010, by Richard Salmon

It’s quite common to see major mistakes taken with an air conditioning system, especially with regards to power usage and electrical efficiency. From basic filter mistakes to major errors in air conditioning unit placement, air conditioning blunders can cost a lot of money and cause even more problems.

These three mistakes pop up time and time again in air conditioning installations. If you’re aiming to keep costs down, it’s best to ensure you’re not making them yourself.

1. Changing the filter infrequently.

Air conditioning filters need to be changed regularly, else they’ll become inefficient and significantly increase the cost of running an air conditioning system. For tropical climates, it’s best to change them every month, and occasionally even more frequently. Drier climates can get by with less frequent changes – once every two or three months is generally okay.

2. Poor unit placement.

Positioning your air conditioning unit in a sunny section of the room will significantly increase the costs of cooling your home. Not only does the unit have to fight harder to cool the air, but your room will naturally increase it upon exiting the unit itself. Place your air conditioner somewhere energy efficient – dark areas and non-crowded parts of the room are best for air flow.

3. Pairing with a humidifier.

This error depends on your climate, but is generally a poor idea. When paired with a humidifier, it’s possible to waste energy and create an uncomfortable climate. Using two air appliances together isn’t a major problem,but is still best avoided for ideal energy efficiency.

If you’re not DIY-savvy and prefer a helping hand, get yourself an air conditioning service...
