LEED Schools In Houston Get More Than an E For Effort

We send our children to school every day and ask them to learn. They are, after all, the future of our world; and so we ask them to learn about right and wrong, learn about the world, and learn how to take care of each other. But do we want them to learn how to take care of the world, too?

That is what LEED Green Building schools in Houston and around the nation are doing. They are teaching the children, through example, what it means truly to earn an A for awareness of the environment’s needs. They stand for the future of America as a benchmark of creation care.

LEED Green Building schools are K-12 schools that are tailor-made to produce an environment safe and healthy for children, comfortable for teachers, cost-effective for the taxpayers, and easy on the environment. By addressing the uniqueness of school spaces and children’s health issues, LEED for Schools provides a unique, comprehensive tool for schools that wish to build green with measurable results. The rating system addresses issues such as classroom acoustics, daylight and views, mold prevention, and environmental site assessment.

In addition, Green schools cost less to operate, freeing up resources to truly improve students’ education. Their carefully planned acoustics and abundant daylight make it easier and more comfortable for students to learn. Their clean indoor air cuts down sick days and gives our children a head start for a healthy, prosperous future. And their innovative design provides a wealth of hands-on learning opportunities.

No longer must they learn through books about environmental safety and/or green projects around the world. Instead, they can learn hands-on at school – through observation and through practice.

Houston has taken the lead around the nation in building green schools. The Houston chapter is dedicated to showing school district leaders how the LEED FOR SCHOOLS process can benefit them. Other leading organizations in the area are also committed. Earlier this year, the Houston-Galveston Area Council joined with the Houston chapter to produce a year-long symposia to educate the public and educators about the facts and costs for LEED FOR SCHOOLS.

They ideally will have all their schools “Go Green” over the course of the next 10 years.

Other cities are following their lead. Salt Lake City, Grand Rapids and Seattle are all among the top cities with at least three green schools. And more are being built monthly. Both students and parents, teachers and administrators see the need and the benefits for green schools, and are lobbying for all school to change their ways.

For students and teachers, green schools mean reduced incidence of asthma, decreased absenteeism, improved academic performance and increased teacher satisfaction. For parents, green schools offer the confidence that comes with knowing their children spend their days in an environment that is both healthy and conducive to learning.

Green Schools get more than an E for effort. They are the bright and healthy future for our children.

Goes to the Animals: Vibration and Noise Control

Noise and vibration control is an issue that is much more common than one might originally think. In fact, it can creep up in the most unlikely of places. A good case in point is animal lab environments. Indeed, ALN Magazine recently ran an article titled “Noise & Vibration Considerations for the Animal Lab Environment.” Therein, the publication pointed out, “In the lab animal facility setting, noise, sound, and vibration affect the life cycle, interaction, and behavior of animals.” However, because “the impact of noise, sound, and vibration is a largely undocumented factor in the research,” it’s an often overlooked issue.

“If the sound pressure levels get too high,” the article continues, “there is a negative impact on animals and structures.” Vibration control, however, is just as important to these animals as noise control in that it “is a driving force behind radiated sound.”

Obviously, exposure to noise and vibration can be detrimental to an animal’s hearing, but the risks don’t stop there. “Sound and vibration can [also] have a physical impact on animals.” Even more startling, “Smaller animals are more susceptible to the affects of sound and vibration over time and will adapt or adjust accordingly. In some cases, mutations may result from exposure to undesirable conditions.”

How can animal laboratories mitigate these problems? The magazine notes, “The designers can control items that are constant disturbances that may greatly impact the animal community. Items within the designer’s control include ventilation system design, machinery vibration isolation, wall construction, lighting selection, and computer terminal placement.”

During the design process, animal labs may want to consult with a producer of custom-molded rubber and rubber-to-metal bonded parts for noise and vibration control. A world leader in the creation of rubber molding and rubber-to-metal bonded parts can help to create an environment that is not only safe for the animals being kept there but is also conducive to a healthy work environment for the people who are employed there.

The Vibro-Insulator line of isolators and mounts, in particular, aid in the control of noise, vibration, and shock. Selecting the right type of mount for an individual animal lab’s specific applications can prove tricky, however. That’s why consultation with an expert with reputable qualifications in rubber molding and rubber-to-metal bonding can be very beneficial.

Of course, once professional advice has been obtained, browsing the Vibro-Insulator catalog allows animal labs easy navigation so they can select the correct mount for their application. Rubber Vibro-Insulators come in a variety of styles and sizes to handle most vibration isolation problems. Most of the mount styles are designed to be used in either the compression or shear direction.
Selection of the proper Vibro-Insulator for a specific application boils down to a multi-step mathematical function that an expert can calculate for the lab or into which the lab’s design team can plug the following information:

1. The maximum load that must be supported.
2. The number of mounts supporting the load.
3. The frequency of the disturbing vibration.
4. Any restrictions on the size or style of the mount based on space limitations or assembly considerations.

Recycle, Reuse and Reduce - A Quiz For Families Who Want to Recycle Cans


Recycle, Reuse and Reduce - A Quiz For Families Who Want to Recycle Cans

Does you family recycle aluminum cans? Do they do it to get a little extra cash or because it is the responsible thing to do? How much do they, and you, know about what happens to the can after the soda is gone? Here is a quick true and false quiz on recycling. It will only take 2 or 3 minutes to find out what you know and what you need to know about the importance of families recycling.

Circle the answer for each of the 6 questions. Now test the other members of the family.

1. In the time it takes you to read this question, 50,000 12-ounce aluminum cans are made.

                  True or False

2. When you recycle one aluminum can you save enough energy to equal a half gallon of gasoline?

                  True or False

3. There is no limit to the amount of times aluminum can be recycled.

                  True or False

4. We use over 80,000,000,000 (billion!) cans a year.

                  True or False

5. At one time, aluminum was more valuable than gold.

                  True or False

6. More aluminum goes into beverage cans than any other product.

                  True or False

Surprise! All of the answers are true.

Did you know that for every $10 spent buying things $1 or 10% goes for packaging that is thrown away. Packaging, and that includes aluminum cans, represents 65% of household trash. Wow. What a waste of money and resources. We can do better than that.

Our family is making a special effort to Recycle, Reuse and Reduce. Will you join us in helping to protecting our earth and natural resources? Maybe your family could put up a special box to save aluminum cans for the recycling center.

Recycle Your Second Hand Clothes

Landfill in the UK is becoming a huge problem. With the drop in the price of recycled products, the issue is what to do with all of the waste that we produce. The breakdown of waste in landfill sites creates huge amounts of the greenhouse gas methane. There are also many products that will not breakdown and will remain in the environment for ever with the potential to contaminate water supplies.

Traid, a charity specializing in the recycling of textiles reports that 900,000 tons of shoes and clothing are thrown away each year in the UK. Only 200,000 tons per year are recycled and the rest is dumped in landfill. The government estimates that similar amounts of between 550,000 and 900,000 tons of textiles are thrown away each year.

In addition to the problems of waste and landfill in the UK, there is also the consideration of the energy used and waste generated by the manufacture and distribution of clothing and textiles. Growth of cotton uses a huge amount of chemical pesticides and environmentally damaging cultivation methods. The manufacture of man made fabrics also has a huge environmental impact with. Demand for polyester the most widely used synthetic fabric has almost doubled in the last 15 years. The manufacture of polyester uses large amounts of crude oil and an energy-intensive process. It releases emissions including volatile organic compounds, particulate matter, and acid gases such as hydrogen chloride, all of which can cause health problems for workers by causing or aggravating respiratory disease.

Second hand clothing is becoming more popular as people begin to recognise the real costs of fast fashion. Consumers are becoming more aware of their buying choices and ways that they can help the environment.

Finally, there is one more great reason to recycle second hand clothing. Just because you are fed up with a piece of clothing or it does not fit you nay more, it does not mean that it has no worth. You can make sure that the worth of your second hand clothing is realized by swapping it at a swishing party on a clothes swapping website, selling it or donating it to your favorite charity.

This article was written by Ceri Heathcote for posh-swaps.com, a website for swapping, buying and selling second hand and vintage clothing.

Clothes swapping and buying and selling second hand clothes is a great way to reduce the impact of fashion on the environment and to save money.

The World Energy Crisis


The World Energy Crisis

The world has some decisions about sources for future energy. The increase in population and increasing demand present a problem. The cost of conventional non-renewable energy sources is on the rise. Oil, gas, water, coal, and other natural resources have a limit to their supply.

Gas, Oil and petroleum products are more expensive than ever, and the supply is running thin. Many may think that the planet may never run out of these however it seems that drilling these supplies is becoming ever more difficult. There have been three major energy crises thus far.

Due to the shortage of resources and decreased output, the cost of these energy sources has increased rapidly over the years.

How long will it take before all of these resources are exhausted? The truth is that we really do not know. Experts say that 50% of the world’s supply of available oil has been exhausted. Every day the demand is increasing and it could take mere decades to exhaust the supply of crude petroleum.

What could possibly be done about this situation? How can we as a society cope with the energy crisis at hand? What can we consumers do about this? We can all start by understanding the importance and impact that energy has in our lives. These supplies of energy should not be taken for granted. Additionally we should avoid wasting energy.

There are simple things that we could do to conserve such as getting involved with a car pool, check our car tires for proper inflation, and using fuel efficient vehicles. If we can cut down on our use of fuel and oil in everyday activities we can be further prepared for the impending energy crisis.

Another way that we can cope with the energy situation is by utilizing renewable energy sources. Solar and wind power systems are becoming ever more available. These power solutions are feasible, cost effective and environmentally friendly. In addition, you save on your power bill and help contribute towards a better future for our world.

Make power at home with solar and wind energy to eliminate your power bill. Get our complete guide at EnergySolutionsDIY.com.

Responsible For Residential Solid Waste Removal?


Responsible For Residential Solid Waste Removal?

Residential solid trash, also called urban solid waste and municipal solid garbage, is refuse that normally comes from households. It is either in solid or semisolid form. There are five general categories of solid garbage that include:

1) Biodegradable waste: food and kitchen
2) Recyclable material: paper, glass, bottles, cans, metals, and certain plastics.
3) Stagnant rubbish : construction, dirt, rocks, and debris.
4) Assorted waste: clothing, plastics,etc.
5) Household hazardous waste: toxic such as paints, chemicals, light bulbs, spray cans, fertilizer and pesticide containers, batteries,etc.

Cities and towns generally contracts out solid garbage removal services. They will submit bids, assess each bid, and recommend a company. The rubbish company will bill the city or town. These companies are privately owned so if a person has a lot of waste after a project such as home renovation, they can hire a garbage removal company to remove the refuse.

Because of environmental regulations and a growing demand for a cleaner environment, junk companies are now performing the following services:

Recycling Programs: Curbside recycling is usually available to all residential customers. Customers will separate their recyclables according to paper and plastics for curbside pick up. Depending on the contract, this is normally done every two weeks. There can be special recycling programs such as Christmas tree recycling. The trees are then made into mulch. Other special programs a town or city can offer are Spring and Fall Clean Ups. They are designed to encourage residents to get rid of large amounts of garbage.

Hazardous Materials: Every year, millions of people accumulate such hazardous waste products as batteries, paints and stains, cleansers and polishes, motor oil, antifreeze, pesticides and herbicides,etc. These are dangerous to the environment, people, and animals. A rubbish removal service is trained to remove these products safely and responsibly. They will sort and categorize the hazardous materials before storing them in containment units. The contracted hazardous waste hauler packs the items in drums and sends them to hazardous rubbish incinerator or other treatment facility for proper disposal. Some materials, such as used motor oil, lead-acid batteries and antifreeze, are recycled.

Compost Services: Many cities and towns offer a compost service. They will provide compost bins for people to place such items as kitchen food garbage, newspaper, and other items that can be composted. A contracted junk removal company will pick up the compost left on residential curb sides.

Energy Recovery Plants: Plants that convert rubbish to energy are popping up all over the country. These plants burn garbage to heat water which produces steam in much the same way power plants burn coal, oil, natural gas, or wood. The steam can cause a turbine to produce electricity. Junk removal companies that have energy recovery plants in their area will make use of these services.

Special Handling waste Removal Services: Cities and towns will have a contracted service to remove large items such as tires, air conditioners, household appliances, and construction debris. Tires are sent to a recycling or recovery facility and household appliances, after chlorofluorocarbon gas removal, are taken to recycling stations.

Individual Contracted waste Removal Services: There are situations where a person has too much waste to be removed by a city or town removal service. They will then enlist the services of a private company. They are trained and certified to dispose of waste, compost, and recycle residential goods. For a nominal fee, a company will come to your home and remove all of your excess trash.

Because of growing environmental concerns, most companies dispose of waste in ways that will have the least environmental impact. You will feel good knowing that you are doing your part to protect and conserve the environment.

It is important for individuals to be mindful of what is in the trash. That way, the environment can be better protected. If you are looking for a junk removal and rubbish company located in the GTA please visit us at: Garbage Removal Toronto.

Saving Energy with Your PC

Green and Clean Computing

Little thought may be given to the energy consumption of computers, but as more and more computers are purchased each year, it is not just the number of computers that forces increased energy consumption but the way in which computers are being used that adds to the building energy burden. Research has shown that most computer desktops are not being used a great deal of the time they are running and are left on for long periods of time. As with other forms of energy consumption, electricity is wasted when it is not being used and this burns fossil fuels that emit carbon dioxide into the air and cause smog, acid rain and other detrimental environmental side effects.

The typical desktop computer consists of a system unit which houses the central processing unit (CPU), a monitor and a printer. The CPU may require 100 watts of electrical power; the monitor, which may be 15 to 17 inches, may require another 50-100 watts; a laser printer can use as much as 100 watts or more while ink printers use as little as 12 watts while printing. The cost for operating a 200 watt system all day and night, everyday, would be $125 annually, while the cost of operation for normal business hours of 40 hours per week would range around $30 annually. Considering the tremendous benefits derived from using computers, this figure may not appear extensive, but when multiplied by the many computers used on a daily basis in this country, the total grows phenomenally.

There are many ways to reduce personal computer energy consumption. Computers, printers and monitors can be turned off when not in use. Many years ago, it was considered harmful to the computer if it were turned on and off periodically during the course of a day. However, the internal circuitry of personal computers is designed to be protected from power damages that might result from on and off switching. Doing so will not substantially affect the computer’s useful life.

The use of screen savers wastes energy and should not be used. They go back to the days when, if not used, images would be ingrained on screens if they remained on too long, but updates in technology have long made the use of screen savers unnecessary.

The United States Environmental Protection Agency has also developed technology for computers and monitors that can be programmed to automatically power down to a lower power state when not in use. This “sleep mode” can reduce energy consumption by 60% to 70% and these “Energy Star” computers serve to gain efficiency without any loss in computing performance.

Green computing extends beyond the personal computer to the use of related devices and materials. For example, paper waste can be reduced by printing as little as possible and only when necessary, recycling waster paper, using electronic mail instead of faxing to eliminate the need to produce a hard copy, and trying to print on both sides of the page when possible. In addition, printer and toner cartridges can be recycled. Although this is a practice that has been discouraged in the past by printer and toner cartridge manufacturers, such recycled cartridges save resources and reduce pollution and solid waste. Disposing of electronics as well can be done through recycling agencies to reduce waste and provide for recycling of functional equipment.

Finally, green computing also means not buying new equipment unless there is a real need for it. Close investigations can be made regarding upgrading hardware or software before purchasing a new computer. However, if the determination is made that a new computer system should be purchased, there are “Energy Star” computers, monitors and printers on the market. In addition, ink jet printers use 80% to 90% less energy than laser printers and soon, even “Green Computers” will reach the marketplace for sale.

5 Easy Tips For Saving Money and Conserving Water


5 Easy Tips For Saving Money and Conserving Water

Everyone is looking for ways to save money and help conserve our natural resources. There are many methods that are easy to start in your own homes, but one very simple and obvious way to save is by reducing water consumption. Here are just a few easy water saving tips that you can begin doing today.

1.  Turn off running water in your sink or shower when you’re actually using the water. You can easily fill the sink with a enough water to wash your face, or fill a cup to brush your teeth. You may consider turning off the shower faucet while you’re washing your hair and then turn on again to rinse. Think about how much water is wasted. The same goes for dishes in the kitchen, turn off the water until you’re ready to rinse.

2.  There are low-water consumption toilets available that use only a couple of gallons of water each time they are flushed. If you have a standard toilet, one green living tip you may consider is placing a plastic bottle filled with sand into your toilet tank. This little trick helps the tank fill up faster and use less water.

3.  The laundry is another area where it is easy to waste water, and just as easy to save. Do your laundry in large loads rather than several smaller ones.

4. Limit your water waste outdoors. Don’t wash your car or driveway as often as you have been, and when you do, turn off the outside faucet until it’s time to rinse your car.

5. Look throughout your home, checking the faucets, toilets and pipes for any leaks. The very smallest of drips coming from a leaking pipe can eventually cost you a lot of money. Fix any leaks that you find.

If you are looking for simple ways to save the planet and save yourself money, start at home with these 5 easy steps. The planet and your wallet will thank you.

Gasification Sees a New Dawn and How it Will Benefit Us All


Gasification Sees a New Dawn and How it Will Benefit Us All

If you search for gasification and terms like “wood stove” on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.

So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?

What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.

This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.

Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.

Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.

These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.

Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.

Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.

Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.

Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.

Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.
