Las Vegas Aims to Go Green with Solar Energy

Las Vegas SignLas Vegas’ blinding lights and sparkling neon signages may not be the first thing you think of when talking about renewable energy, but some of the city’s largest casinos are planning to change that.

Discreetly shrouded among vibrant resorts, a gleaming Eiffel Tower replica, and a black glass pyramid that shoots a straight beam of white light into the sky, sits an array of solar panels so extensive that it has been considered as one of the largest in the country.

You may be surprised to find out that on top of the Mandalay Bay Convention Center — one of the biggest privately owned convention centers in the entire world, with a land area of 1,000,000 square feet — sits a colossal, 20-acre array of solar panels.

Wynn Las Vegas, Las Vegas Sands, and MGM Resorts, three of the major casino businesses in Las Vegas, have began planning on going completely solar. This move is motivated by the rise in demand for more environmentally friendly energy sources as well as the decreasing cost of solar energy gathered from California and Nevada.

“Not so fast” says NV Energy

NV Energy LogoThis move, however, does not come without a price. NV Energy, Las Vegas’ sole electricity provider, demands that the casinos pay millions of dollars as an “exit fee”. The reason for this is that the casinos’ properties account to more than 7% of the regulators’ revenue. Apparently, once they decide to discontinue their dependency on NV Energy’s services, other customers will have to endure momentous price increases.

An energy economist from the American Solar Energy Society, Bill Ellard, believes that energy regulators and providers are only making it harder for businesses to switch to solar energy in order to protect their revenue.

In fact, MGM Resorts has already harmed the provider’s profits after deciding to take steps in reducing energy consumption. Aside from assembling sun-powered panels, which supposedly has the capability to provide energy to one thousand residential homes for an entire year, the resort also began replacing all 1.3m bulbs with energy-saving LED lights. Unfortunately, to provide enough power to casinos filled with pools, nightclubs, and air-conditioned hotels rooms, the said companies will need to find a larger solar farming area as their rooftop properties will not be enough.

In the event that the resorts push through with their decision to go green, they will be asked to pay a total of USD 126.5 million. This price has been decided by the electricity companies, which they said is enough to forestall the steep price hikes.

The fight for alternative energy

Las Vegas Solar PlantLas Vegas Sands and MGM have yet to fully decide which option to go with. Should they proceed with solar energy and pay up, or should they continue utilizing NV Energy’s services? With ridiculously high exit fees, the lawyers of Wynn Las Vegas are wondering whether these fees are even legal. “The PUC (public utility commission) has simply made up rules as it goes along so as to discourage any applicants from exiting [NV Energy’s] service,” said their lawyer.

With Las Vegas’ plans to likewise completely utilize alternative energy by 2017 — this includes public parks, government facilities, fire stations, etc, — the city will be the first major metropolitan to do so.

The “Sin City” is not that sinful, after all

All these steps towards a greener, more environmentally-friendly Las Vegas are motivated by the sole purpose of eliminating the bad notions about the city. “The more we can dispel the myths around Las Vegas the better destination it is, ” said MGM Resorts’ chief sustainability officer,  Cindy Ortega.

What do you think of Las Vegas’ steps to go green? Do you think the PUC’s are deliberately oppressing the solar industry? Tell us your thoughts by leaving a comment below.

Coral Reefs in Florida are Rapidly Disintegrating

Florida reefsThe northern portion of Florida’s barrier reef is disintegrating much faster than scientists expected. Recognized as the only barrier reef  in the US, Florida Keys’ coral reef is a well-known tourist destination that helps the economy by contributing billions of dollars in the US’ travel industry every year.

The disintegration, which shows no signs of stopping or slowing down, poses a serious risk to all aquatic animals inhabiting Florida’s coast.

What are coral reefs, anyway?

Corals are some of the most ancient structures of biological origin here on Earth, with fossil records of them dating back to approximately 400 million years ago. They are members of the phylum Cnidaria, specifically under the Anthozoa class.

The importance of coral reefs

Coral reefs can be compared to rainforests. Despite occupying only a tenth of one percent of the ocean floor, these reefs provide a safe haven for one-fourth of all known aquatic animals in the ocean.

Our society today is highly dependent on the ocean for being a major source for food and natural resources. It is because of this that scientists around the world are doing everything they can to  prevent, minimize, or completely eradicate the causes of its destruction.

The cause of disintegration

Carbon dioxide emissionMiami scientists have already traced down the major cause of the reef’s rapid disintegration: it’s the water itself.

Ocean acidification lowers the pH of the ocean water, making the water more and more acidic. This is caused when too much carbon dioxide (CO2) is released into the Earth’s atmosphere and eventually, all the excess carbon dioxide will be absorbed by the ocean.

Prior to this unfortunate discovery, scientists thought that ocean acidification won’t be a cause for concern until the next 40 years or so. The scientists were significantly alarmed when they found out that acidification is already causing some serious environmental issues today.

Chris Langdon, one of the senior professors of the University of Miami and a leading scientist in this study, stated: “We don’t have as much time as we previously thought.”

Just how much damage has been done to the northern portion of Florida Keys’ reefs? In the last six years, the foundation of the corals had already lost a whopping six million tons of limestone. That’s one million ton of limestone ruined every year.

Ocean acidification isn’t the only issue we are currently facing. As we continue to pump out excessive amounts of carbon dioxide into the air, the ocean will continue sucking up the gas which will result in the significant rise of temperature of our ocean’s waters.This results in the melting of polar ice which eventually causes the sea levels to rise.

While carbon dioxide is naturally produced by living organisms through respiration and other biological processes, the major cause of excessive CO2 emissions are far from natural. Destructive human activities such as deforestation the burning of fossil fuels greatly exacerbate the greenhouse effect.

Completely getting rid of these unnatural causes is still pretty much impossible, but scientists and researchers have already developed numerous ways of preventing or minimizing these effects.

Alternative energyAlternative energy sources such as the wind, biomass, geothermal and solar energy have been developed to generate energy without having to deplete the Earth’s natural resources.

With the loss of coral reefs and the speedy rise of Earth’s sea levels, now is the best time to start taking our environment issues seriously.

How do you help minimize the effects of carbon dioxide? Tell us about it in the comments below!

Mythbusting Global Warming

There are numerous debates not only in our government but also in our communities that GLOBAL WARMING is just a myth. Let us explore the sides of the changes that are happening in our planet and find out who’s causing it.

The US is home to 5.7% of the world entire population. Can you imagine how much carbon dioxide emissions the country alone produces?

environmental pollution

About 25% of the CO2 emissions on earth is contributed in the US alone. With other countries both developing and developed add to these emission the earth’s atmospheric layer is broken down bit by bit. Hot air is trapped within the earth that may cause extreme heat or cold in numerous places all over the globe.

Prices of commodities did not increase alone, factors such as number of population, increase of demand and supply of both raw and recycled material has significantly hit the roof. Unstable markets pose as a threat to both small and large business wherein trade is vital. Along these changes come global warming wherein our oceanic waters have warmed to a full degree Fahrenheit since the 70’s.

If the artic ice could only yell help I melting!!! It will. With its rapid disappearance, the region might experience summer by 2040 or earlier. Species who live in this type of habitat would surely be affected by the the loss of sea-ice. Creatures and plant below our seas are also affected by climate change. Coral reed which are know to house indeginous cultures and marine species are highly sensitive to the changes in water temperature. In response to the stress brought forth by these phenomenon, coral reefs die and so is the biodiversity that comes with it.

If global warming continious, we would feel the direct heat of the sun in 400 years. You might re-think and say who cares I am gone by then but hey don’t you want the future generation to see what the real beauty our planet beholds? All human beings are the current contributors of planetary warming, no matter how big or small the contributions towards hazardous emission that depletes the environment is, it is still a major factor.

The propose change our counter for climate change is to begin with one self. We must reduce our emission and save the environment resources. There are numerous proposed alternatives that would aid as viable solution to the growing effects of global warming today.

Plastic to Oil Conversion- The Art of Renewable Energy

From a simple observation a now renowned Japanese inventor named Akinori Ito has produced a one of a kind technology that allows us to convert plastic into oil.

The growing cause of plastic pollution has affected not only living organisms but the majority of the planet. It has taken up too much space and accumulates at a very rapid pace. With the population constantly growing and the demand for plastic consumption tops, more and more evidence of climate change us not only seen but experienced as well.

Oil-generated-from-plastic

The general public is not aware that most of the plastic materials that they use us made up of 98% petroleum products that is converted back into oil. Oil that is extracted from used plastics is used as an alternative for fossil fuel energy generation, power for our cars and other means of transportation. With millions of plastic waste produced every year, most of it is floating in the great Pacific Gyre that kills albatross, seagulls and marine life by indigestion and suffocation. Imagine saving money if you could convert these plastic materials into alternative oil at the same time saving the environment?

How is it achieved?

The conversion of plastic to oil involves a process called thermal degradation wherein extreme heat is applied to plastic which is feed stock to the innovation made by Mr. Ito. The gas that is produced from this process do not escape the chamber, it is redirected into a cylinder filled with water. Water and gas then co-mingles thus producing alternative oil derived from plastic. The oil is then separated from the water residue.

Depending on the feedstock, plastic may produce heavy oil, gasoline, kerosene and diesel. All these types of oil are the used for our cars, energy generating turbines and heaters for our homes. With millions of tons of plastics produced, millions of tons of oil are just sitting in our sanitary landfills waiting to be found. Buried treasures are found in places and forms that you would never think of it possess. The art of renewable energy just keeps on expanding. Companies are starting to invest in the technology of Mr. Ito to help their cities lessen the growing pile of plastic waste.

Challenges of Wind Farms

Wind power is a renewable energy source that does not rely on fuel. It does not generate harmful emissions into the atmosphere that depletes our ozone layer. Despite that, there are numerous challenges faced by wind farm operators and questions that need to be address. One of these is how stable is its power supply?

Wind energy is fuel by the earth’s irregularities, providing an attainable source of electricity. It is proven that power acquired from the wind has a lesser environmental impact than those power plants run by fossil fuel. Wind energy is also a more cost efficient power source that we use today.

WHAT ARE THE CHALLENGES FACED BY WIND FARMS

Although wind energy is the cleanest source of power, its construction and operation has been one of the major issues raised by locals. In a landscape view, wind turbines are clearly visible and not that intrusive however, once you get close to it you will see that a single wind turbine takes up too much space. Wind farms also possess potential risk on local ecology and the wildlife in it. Sound is also a factor that a wind farm faces today.

CONSTRUCTION OF WIND FARMS

Wind Turbine Construction
Wind Turbine Construction

Research shows that some of the windiest site to place wind farms are heavily protected by mountainous regions. Other large areas that are ideal for its construction are protected by conservation restriction. Wind farms constructed near the sea are costly and difficult to build however it is achievable. Wind turbines ideally need to operate in exposed sites where they could make use of the prevailing winds. These structures are massive that they invade space.

SOUND EMISSIONS

Sound emission from wind farms are divided into two categories: Mechanical and Aerodynamic sound. The earliest wind turbines have terrible insulation and design that produces ruckus. Mechanical noise created by the gear box and generator were the cause of annoying sound. The designs of the blades were also a factor on why the previous wind turbines were another source of the sound as well. Despite this, newer versions of wind farms have tried to fix these issues making sound emissions a lesser concern for the individuals living nearby.

ECOLOGY AND WILDLIFE CONCERNS

Wind farms evade so much space that it affects the ecology and wildlife in it. They cause temporary or permanent habitat loss in sandbanks, water body and land areas due to disturbance. Migratory routes are also affected by wind farms; birds and bats collide into the rotor blades injuring or killing these species unintentionally. Light emissions attract birds that subsequently increase the risk of collisions to these massive structures. Marine mammals induce permanent or temporary threshold shifts with their perceptions through the significant masking of sounds cause by construction and pile driving. Vibrations, clouding and sedimentation during wind farm construction damages fish eggs and disturb their spawning grounds.

Despite the challenges faced by wind farms, research and assessment are made to alleviate the impact on the environment. Potential problems are easily identified through the process and were given counter measures to mitigate the impact of its effects.

Turning Plastic into Petrol

The newest and most cutting edge technology to reach production in the green energy sector solves two problems at once… oil shortages and pollution from plastics. Through a process similar to gasification, scientist from United Nations University have invented a machine that actually converts plastic trash into usable oil, diesel and refined gasoline.

Nowadays, our environment has been experiencing bigger problems than people face, and one of these problems are plastic. People are solely dependent on the usage of plastics. Using plastic is inevitable for many people, plastics are everywhere and when they are done using these things, they will all end up being dumped and considered waste products.

In America alone, there were more than 30 million tons of plastic wastes accumulated in the year 2010. Only 8% of those millions of wastes were recovered for recycling and somewhat reusing purposes.

PLASTICS ARE EVERWHERE

Plastic products are everywhere, you will never get a chance to not see them wherever you go. You use plastics when you eat, shop, and even cook. People’s lives have become somewhat dependent on the usage of these materials.

THE PROBLEM

Things that are made of plastics are non-biodegradable, these things take up from 50 to 100 years to degrade. There are no natural process yet that can make plastics degrade in a fast pace of time. In that case, a person is left with no choice but to throw the plastic away, burn or bury it. Which of course results to litter… everlasting litter!

Garbage is not the only problem people face when it comes to plastic materials, plastics are made up of toxic chemicals — xylene, ethylene oxide and benzene — and as we know it, these chemicals can cause diseases and disorders to people, animals, and even to the environment. And did you know that a plastic material is made of Bisphenol A (BPA) that makes a person become more at risk of breast cancer when he/she is exposed too much on this toxin?

THE SOLUTION

Decreasing the problems given by these plastic materials is a hard task for many people because these materials have become part of their daily living, meaning, one day is not complete if no plastic will be used. True to what was written, plastics are everywhere, and there are ways on which we can reduce the problems that people are facing because of excessive usage of plastics:

  • Use Eco-Friendly or Biodegradable Bags
  • Reuse Plastic Bags
  • Donate Plastic Bags to Recycling Centers
  • Not Throwing Away Plastic Bags after using

There’s another way!

Yes, plastic bags and plastic materials are great helpers for a person’s daily living, they can become trash bins to trash, and now, plastics can also make your home feel warm as they can become petrol products! Thanks to the modern technology and the people behind it as they have made a device that can turn plastic materials into useable petroleum.

 

To begin with, plastics are of course made up of petroleum, but this petroleum is not the same as what fuel is made of.

To turn plastic waste into petrol, when these materials are put into the machine, the temperature of the machine increases as it heats up the plastics and ensnaring the vapors made in a system of pipes and chambers.

This innovative machine makes these vapors concentrated to become crude oil, that can be used for heating a house.

A quart of oil can be produced form two pounds of plastic materials, by making use of only a kilowatt hour of energy.

The crude oil that will be produced from these plastic mateirals can be used in a power generator. This oil can even used as gasoline with the help of another machine to refine it.

At the end of the day, what came from oil returns to oil. Plastic came from oil, and it can be converted to become oil and petrol again.

How it Works

poly2petro
poly2oil

NO CONS

This innovation seems to have no downside, this invention only consume electricity that only cost more or less twenty cents. Currently, this machine only processes limited products like polyethylene, polystyrene, and polypropylene, as it holds steadfast to its promise to produce eco-friendly oil, and to decrease the amount of plastic waste in the world.

In a world where the price of oil keeps going up and up, the pollution is emerging, and garbage follow the eight of mountains as they constantly increase, this invention will put a stop to the people’s over and excessive usage  and dumping of plastic products, and convert these things to eco-friendly fuels.

AMERICA HAS IT, TOO!

This innovational device is not the first device that was ever made to turn plastic into something else. A poweplant near Washington, DC, has been conducting similar processes in a small community. They are testing is the plastic-turning-oil device can be used for homes.

Invest in Nanotechnology

nanotechnology self cleaning glassThe flexibility of nanotechnology that allows the molecular or atomical manipulation of matter is now making it a good investment. It has become part providing good and quality products to customers. Nanotechnology is now making products at a higher level of convenience for customers. Today, there are companies who have invested in nanotechnology in order to develop products that can be categorized under molecular biology, microfabrication, organic chemistry, surface science and semiconductor physics.

In fact an organization called Project on Emerging Nanotechnologies had estimated 3-4 manufacturer-identified nanotech products are being released in the market. A product called the self-cleaning glass is one of those that uses nanotechnology. The first company that came up with this product is Pilkington. The Pilkington’s self-cleaning glass uses a coating that was developed for years using nanotechnology. The coating on the self-cleaning glass was developed to perform dual action, the first one is referred to as photocatalytic and the second is hydrophilic. The photocatalytic stage happens when sun reacts with the coating by energizing the nanoparticles of the coating, causing them to break down the organic dirt. On the other hand, the hydrophilic stage occurs when the rainwater spreads evenly and runs off in a sheet, taking the dirt along with it. Because of this dual action, the glass dries of quicker leaving no streaks on the glass.

nanotechnology water repellant clothesAnother manufacturer-product that is now being enhanced by nanotechnology is clothing. Manufacturers are now using a thin layer zinc oxide nanoparticles to make clothing better UV protection. Another would be the use the nanoparticles shaped like little hair or fur to make clothing stain resistant and repel water. An example of a company developing clothing using nanotechnology is Nano-Tex. It is a company that make traditional cotton and silk fabrics stain or spill-resistant. They do this through the molecular modification and attaching hydrophobic whiskers to the individual fibers. These whiskers elevate liquids that make them bead and roll off the fabric surface. They call this Aquapel™.

Nanotechnology is also being applied to cars and eyeglasses making them scratch-resistant. By adding aluminum silicate nanoparticles to polymer coatings and even already scratch-resistant coatings increases the resistance to chipping and scratching. NEI Corporation is one of the companies that is developing their protective coatings with the use of nanotechnology. Aside from the scratch-resistant coating, they also have other nanotechnology-based advanced materials that they were able to produce with the help of their nano-engineering approach that work toward their customers’ convenience.

nanotechnology water resistant clothingAnother product which is made more effective by nanotechnology is the anti-microbial bandage. This was created by the scientist Robert Burell. He came up with a process that will incorporate silver nanoparticles into bandages. He used silver since silver ions has the ability to block microbial cellular respiration. The anti-microbial bandage that he was able to create restricts harmful cells which results to killing them.

Nanotechnology has proven to have a diverse range when it comes to its applications. This type of technology is also being supported by the American government. In fact, they have established a National Nanotechnology Initiative which is a central point of communication, cooperation and collaboration of all Federal agencies engaged in nanotechnology research. The NNI has involved her 25 Federal agency nanotechnology-related activities and 15 of them have been allotted specific budget for nanotech research and development. This is how important nanotechnology is tho the Federal government. They also help in the commercialization of nanotechnology through business development assistance, industry collaborations as well as through regional, state and local activities.

Green Energy Stock Investments

green energy stocksBuying green energy stocks is one way of capitalizing in eco-friendly investments. Green stocks, aka Green Chip Stocks, are relatively new as the concept of renewable energy was just developed over the past decade. They have proven to be very viable and profitable. The public will be able to choose from 10 main types of green energy stocks. These are carbon trading, geothermal, hydrogen fuel cells, organic food, plug-in hybrid electric vehicles (PHEV), smart grid, solar energy, waste-to-energy, wind energy and water. From these main green chip stock categories are thousands of companies that are offering affordable investments for capitalists as well as small investors. Because of the growing number of companies dedicated to generate energy with non-invasive means of doing so, green energy stocks are expected to reach a larger scale in no time.

The gradual growth of the green energy companies participating in the stock exchange also means small public companies making their common stocks available to the public that trade at less than $1 USD. They are called penny stocks or cent stocks in other countries. There also OTC or over the counter penny stocks and these can be debt securities or other financial instruments that are traded through a network of brokers or dealers. They cannot be traded in a formal exchange since these stocks came from small companies that do not meet the formal exchange listing requirements. This is why OTC stocks are also called unlisted stocks. When it comes to this, many recommend to avoid OTC penny stocks since the company where it came from is most likely new and investors do not have a financial history to evaluate, unlike companies who are already listed under alternative energy indices.

green energy stock exchangeThe are several types of green energy stock indices, including global and regional alternative energy focus. The good stock market performance of green energy stocks has paved away for alternative energy indexes that are being tracked by many analysts. An example of a global index is RENIXX or Renewable Energy Industrial Index World. This is considered to be the first global alternative stock index which covers the world’s 30 largest green energy companies. For a company to be included in this index, it requires at least 50 percent of the company’s revenue to have come from wind, solar, biomass, geothermal, hydro power or fuel cell division. On the other hand, a good example for a regional alternative index is ALTEX Australia. Just like the RENIXX index, it was established in 2006 and did track over 120 companies that had an accumulated 52.1 billion AUD market capitalization.

There are other types of indices aside from the first two that have been mentioned. One of them is focused on pure play which means companies who are engaged mainly on green energy. Basing on the term “pure-play”, companies who only have a minor involvement on green energy are excluded from this index. An example of a pure play index is ALTEX Global, which is also under the global index. This is so far the largest pure play index with an combined market capitalization reaching $1.16 trillion USD from companies that have diversified low-emissions energy infrastructure.

green energy stock indexThe next index follows the rule-based approach, which uses pre-defined screening methodology. This way, the process is warranted to be consistent and transparent by an objective Index Committee. An example of this index is S&P Global Clean Energy. This index tracks 30 clean energy related companies from all over the world. These companies belong to clean energy production, clean energy equipment and technology, wind and solar companies which has an accumulated market capitalization of $224 USD billion.

Solar Heating Systems

solar heating systemsThe sun’s power can be used in many different ways and one of them is through solar heating systems. This systems goes through the processes that converts solar energy to heat. Heat can be produced through the use of solar thermal collectors which have three types. These are low, medium and high-temperature collectors.

The low-temperature collector, are flat plates that are used in heating swimming pools and even for heating and ventilation. The medium-temperature collector are also made of flat plates that are used for the purpose of heating air or water for homes and business establishments. The third-type which is the high-temperature collector do not use flat plates, instead, it uses mirrors and lenses that concentrates the solar power harnessing. The high-temperature collector is used to generate electricity. It is important to note that thermal collectors are different from photovoltaics.
solar thermal system
The use of solar thermal systems are now widely used, mainly for heating and this is one of the major applications where such systems used. This is where heating, ventilation and air conditioning comes in. In the United States alone, it makes up for 25 percent of energy consumption. The use of solar heating systems will serve as a great help in saving money as well as save in offsetting the use of fossil-fuel-generated energy. In space heating, solar air heat collectors are used which have two types.

The first type is the glazed solar collector and this works primarily for space heating. The air is heated and recirculated all throughout the building through the solar air panel. Such solar heating system works if and only if it is warmer than the building’s or home’s room temperature. It also requires 2 infiltrations in the building for the whole system to work properly.

The unglazed solar collectors on the other hand are for pre-heating of industrial, commercial and institutional make-up ventilation. This is best for buildings that have high-ventilation volume needs. As a result, it turns walls or sections of it into low cost at the same time high-performance transpired solar collectors. In order to do this, a painted and holes metal that serves as a wall exterior. There is a thermal boundary layer of air which is 1mm thick outside the absorber. The conduction happens from the absorber surface and down to the thermal boundary layer. The layer of air is then strained to the perforations which is led to the absorber plate into the ventilation system of the building.

solar heating thermal systemsAnother solar heating system is called solar roof ponds. It was invented in the 1960’s by Harold Hay. This is a system that includes heating and cooling. It is made of the roof-mounted water bladder that has a movable insulating cover. This system is able to control heat exchange between the inside and the outside surroundings. Controlling can be done through the simple process of covering the bladder during the night and uncovering it during the day. Uncovering the bladder allows it to store heat that can be used during nighttime and the opposite is done to cool the building during the daytime.

Utilizing the sun’s power to heating or cooling advantage is an practical way to save on electricity bills. Aside from the savings, it also makes it easier for people to help the environment since they do not use fossil-fuel-generated electricity. It is like hitting two birds with one stone. This is what solar heating systems allow people to do.

Passive Air Conditioning

passive air conditioningOn warm days, passive air conditioning can be used as an economical alternative to mechanical cooling. Since air conditioners use electricity to run and with high costs related to energy, it would be expensive to cool a building using them. Passive air conditioning takes advantage of the technologies that apply to the building designs that cool the spaces without the need for mechanical help.

Passive air conditioning uses principles in physics to cool homes and business establishments. Building designs that aim to have a cool space use principles of slow heat transfer from the exterior to the interior of the building and removing unwanted heat from the structure. Shading is one way of incorporating the two principles in physics in passive cooling. This is done is several ways.

The first way is to shade windows and walls from direct sunlight while orienting the building towards the winter sun. The building must be facing the east-west dimension. Along with the orientation, further shading must be employed by including location-specific wide overhangs. These eaves should be located above the vertical windows that are facing the equator side. The equator side is defined to be the northern side of the southern hemisphere or the southern side of the northern hemisphere.

passive air cooling Another effective shading that will help in passive cooling is planting trees and other plants on the west side of the building. The west area is prone to overexposure because of the low afternoon sun. The exposure makes rooms really warm since sunlight pentrates the interior during the hottest time of the day. Plants will be able to screen and lessen the exposure of the room in the afternoon. It also recommended to use vertical shutter or blinds as an addition to the plants.

Having good ventilation is also included in the passive air conditioning system. Installing windows on both sides of the building will increase ventilation. However, it is also important to build air passageways such as windows that are strategically placed in areas where the wind or breeze is frequent.

It also recommended to use stacks in buildings, these are tall spaces that will be able to accommodate the breeze. These stacks are also called cooling towers because of its purpose. Stacks are designed to have an opening on the top. This allows the warm air to escape while cold air enters from the windows or openings in the lower part.

passive air conditioning homesAll in all, passive air conditioning is a very good way to save money because there is no machine that runs on electricity to cool a building. It takes advantage of the natural resources that are available just like the wind and plants. Passive cooling can be compared to harnessing the wind for electricity, only in here, it does not produce power but air conditioning.

Passive air conditioning is a good example for the application of buildings structured to blend and work with the environment. It benefits both the people and the environment. It is a great way to achieve a cool living space or business establishment without compromising the financial facet and the environment. This is a simple way on how people can invest in green energy.
