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.

Four million tons of junk mail is sent every year…at least half of which is never even opened. You probably are aware that your name, address, and spending habits are regularly being traded and sold on the open market. By investing half an hour now, you can rid yourself of most of the junk mail for up to five years…and save a few trees while you’re doing it.
So here are a few tips that you can work on to lessen the load of junk you get every day:
Product warranty cards do not register your product…that was done when you purchased it. They are used to fin out about your interests and your income for the sole purpose of junk mail.
When ordering something on the phone, tell them specifically to not give your name and address to other companies for any reason.
Any time you donate money or order a product or service by mail, write on it in large letters, telling them not to sell your name and address.
When the junk come by first class mail, cross out the address and bar code, circle the first class postage and write “refused: return to sender”.
Your credit card companies are the worst offenders and probably sell your name and address more than anyone else. Stopping them is easy; you just need your address and social security number. One call does it all for agencies Equifax, Trans Union, Experian and Innovis. Dial 1-888-5 OPT OUT (or 1-888-567-8688) 24 hours a day.

Plasma Gasification Plant (PGP) projects are being developed by at least five gas plasma technology companies, and there are real benefits to be obtained from this technology for the destruction of Municipal Solid Waste (MSW).
There is some debate still whether the process has been demonstrated to be a vaible technology which can be reliably operated by our waste management companies at reasonable cost and in compliance with all emissions regulations. However, the consensus seems to be largely in acceptance now that the technology is largely proven and inherently cleaner than incineration.
Although, gasification is used as a power generating technology, and gas plasma plants do provide a power feed-in to the local power grid, it should be realised by all that the purpose of selecting plasma gasification is currently that of achieving maximum waste mass destruction. The intent of the PGP is primarily to provide an efficent and clean method of dispoing of large quantities of residual MSW. Plasma gasification, although it does produce energy from waste is not primarliy an Energy from Waste (EfW) or Waste to Energy technology. There are other better proven, more efficient, and potentially always also cheaper ways to produce Energy from Waste, such as incineration.
PGPs suffer a high sacrificial load from the use of power at the electrodes to generate the plasma, and energy is also expended before the MSW reaches the plasma zone in the gasifier in chopping up and ensuring that the particle size of the waste is quite small. For this reason they do expend a large proportion of the power generated just in maintaining their own internal power demand.
However, as a waste destruction method producing an inert residue without creating at the same time high levels of toxic gaseous emissions the gas plasma process excels according to reports made to date. It has every reason to be cleaner as well because the reactions which take place in the plasma state take place so quickly and completely that the toxic organic chemicals produced in other combustion processes simply don’t get a change to be produced.
For a waste management process PGP therefore holds a very good prospect of adoption, as it is a process which is very efficient at diverting waste away from landfill, and thus scores highly among local authority waste disposal engineers who are constantly seeking to comply with regulations to reduce the amount of organic waste sent to landfill.
The PGP process however, also holds another merit and that is that it is being viewed more favourably by the public than incineration, and one main reason for that would be its clean emissions record when compared with incinerators historically.
Throughout Europe the requirement for BMW to be reduced by ever larger percentages necessitates the use of new technology to achieve this high rate of waste diversion, even after high recycling has also been achieved.
Look out for a plasma gasification plant appearing in a district near you soon, and look favourably upon it!
Steve has built a great web site where there are a lot more facts about gasification. This is a hot subject indeed for this technology which has become an essential read for all those who appreciate renewable energy issues and are interested in taking action to reduce the impact of climate change.Article Source: http://EzineArticles.com/?expert=Steve_D_Evans

Silicon Valley is known for both innovation and hype. Recently, this pool of innovation has extended beyond bandwidth to the protection the environment. Google and Yahoo, the search engine giants, are both headquartered in the Valley and have been making headlines by greening their offices, reducing energy consumption, and carbon trading. The PR motivations are obvious, but are the green benefits really there? To set apart the hype from reality, we have analyzed the green value of both Google and Yahoo’s headquarter facilities.
We looked at the ecological services provided by green landscape features such as trees and open space (i.e. grass). Grass and trees are pervious surfaces, meaning they allow water to permeate into the ground. Roofs, sidewalks, patios, and asphalt parking lots are examples of impervious surfaces, where rainwater drains into the public storm drains. Heavy metals, oil, and other pollutants are carried off parking lots in rainwater, which often lead directly to open water habitats, where fish, birds, and reptiles live.
In terms of ecological services, trees and grass have been proven to:
1. Remove and store carbon from the atmosphere,
2. Remove certain airborne pollutants,
3. Permits rainwater to seep into the ground as opposed to draining into the stormdrains, and
4. Remove certain waterborne pollutants.
Here is a look at how green Google and Yahoo really are and how the measure up against each other.
Google Green Report
Google’s headquarters, the Googleplex, covers 44 acres, nearly 50% of which is grass or tree canopy. This is an impressive paved to open space ratio. The grass and trees on the Googleplex remove roughly 2 tons of carbon from the atmosphere per year, or 0.04 tons per year per acre. In addition, 530 lbs. of air pollution are removed per year (e.g., ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, and particulate matter), or 12 lbs. per year per acre. It was assumed that the parking lot of the Googleplex is asphalt, and not a type of porous pavement, so the cost of managing rainfall runoff from the Googleplex is $4,474 per year, or $103 per year per acre. The abundance of grass and tree canopy on the Googleplex go a long way to offset the water quality impacts of the paved surfaces (mainly the parking lot). On average, the grass and trees reduce water pollution by 6%, as opposed to the entire property being paved.
Yahoo Green Report
The Yahoo headquarters, Yahooplex, covers 28 acres, a third of which is grass or tree canopy. This is a classic ratio of paved to open space for large office complexes in California. So far, par for the course. The Yahooplex removes 0.36 tons of carbon from the atmosphere per year, or 0.01 tons per year per acre. 114 lbs. of air pollutants are removed per year, or 4 lbs. per year per acre. In terms of rainfall, the cost associated with runoff is $9,219 per year, or $331 per year per acre. The grass and tree canopy help offset the paved areas with a 2.3% reduction in water pollution as opposed to the entire property being paved.
The final green analysis?
Google kicks Yahoo’s butt, largely due to the forethought, or luxury, of the Googleplex having 50% of its property surface providing green services. The good news for both Google and Yahoo is that over time, as trees grow, so will the tree’s canopy and mass, thus storing more carbon and removing more air pollutants.
Green next steps for both Google and Yahoo is to:
Install porous parking surfaces, allowing up to 80% of rainwater to seep into the ground,
Install green roofs, absorbing rainwater while reducing cooling costs and energy consumption, and
Planting larger trees on the south and west sides of the buildings to reduce cooling costs and energy consumption.
While we crunched the hard numbers to settle the Google vs. Yahoo green debate, this report illuminates the great opportunity that awaits these two Silicon Valley giants to harness the ecological services of green surfaces.

A Carbon Footprint is Impacted by Fugitive Refrigerant Gas Emissions
The United States and a host of other foreign countries are focusing on fugitive emission tracking for certain industries. The goal is to identify the amount of substances that are emitted into the atmosphere when a refrigerant gas leak occurs. This will give government officials at the EPA a better understanding of the amount of greenhouse gases harming the environment each year and contributing to global warming due to the ineffective management of refrigerant gases.
Fugitive emission takes place when an unexpected leak of a hazardous substance occurs in a system and the discharge is not contained in a vent, stack, or duct. This may be caused by a component failure, poor servicing, or a breakdown in some industrial process. When a system containing refrigerant leaks, these high global warming potential substances cause damage to the atmosphere. Certain refrigerant gases are not broken down in the atmosphere and end up entering the stratosphere and destroying the protective ozone layer over time.
Across the U.S. economy, refrigerant gases or fugitive emissions equal over 300K tons of carbon dioxide each year. Other countries have similar or worse outputs. Many environmental regulations, such as The Montreal and Kyoto Protocols, exist to reduce the escape of harmful substances, like refrigerants, into the atmosphere over time. There are additional goals to reduce the potential for global warming in the near future and to improve air quality in the long term by reducing the emissions refrigerant gases.
A select few refrigerant gases have multiple detrimental effects on the environment. Not only are they ozone depleting substances but they are also chemicals with a high global warming potential (GWP) which places them into the category of greenhouse gases which lead to global climate change. For many reasons, it is important to effectively monitor, track, and report refrigerant gas usage.
The EPA has finalized its rules pertaining to any fugitive emission occurrence, whether through evaporation or a leak. The regulations apply to several industries, including existing and newly constructed facilities with systems using refrigerant gas in their workplace heating and cooling systems. Other industries are industrial chemical manufacturing, electric services, pulp and paper mills, and petroleum refinancing.
Tracking fugitive refrigerant gases is required by facilities owning or operating HVAC-R systems or by manufacturers who produce them. The EPA has identified a number of dangerous compounds, among them chloroflurocarbons, hydrofluorocarbons, methyl bromide, halons, methyl chloroform, and carbon tetrachloride.
A particular concern for fugitive emission problems is with refrigerant gas, because it contains chloroflurocarbons and hydrofluorocarbons, two primary contributors to the weakening of the ozone layer and the increase in greenhouse gas volumes. Furthermore, refrigerant gas is used across many industries in refrigeration and cooling units, ventilation and air conditioning systems, and fire protection systems.
When a fugitive emission occurs, businesses are required to track the refrigerant leak rates and report annul refrigerant usage it to the EPA. One of the primary emissions scopes, fugitive refrigerant gas emissions are an integral part of an organizations carbon management requirements. Of the utmost importance is the determination of the HVAC-R system that is leaking and the capturing of the service event detail related to fixing the leak. Systems containing refrigerant gases must be inspected by EPA certified technicians and all service events must be logged when refrigerants are handled.
The new fugitive emission regulations provide a more standardized approach to thresholds identified by the U.S. Clean Air Act at the direction of the EPA. These include continuous monitoring, tracking of leaks, and reporting of leak repair, and containment.
Web applications and specialized tools can increase an organization’s efficiencies related to HVAC-R system maintenance, improve accuracy of refrigerant inventories thus saving money, and turn manual processes into a centralized, automated work flow. Development firms who specialize in the area. They ensure compliance and reduce the likelihood of substantial fines.

Takes Care of Two Things at Once: Composting Food Waste
Years ago my dad taught me the benefits of composting food waste. It had nothing to do with any type of “green” movement or being environmentally friendly, no, it had everything to do with reintroducing nutrients back into the soil.
Here is what he taught me then and it still holds true today. By burying your food waste and kitchen scraps (no steak bones though), you are providing a quality food source for the creatures that live in your soil. From micro organisms and those creatures that the human eye can not see, up to worms, which of course we do see.
See, what happens is these creatures eat the food (and of course each other) and then finally the worms eat basically everything and their castings (worm poop) create the best nutrients your soil could ever have. By continually supplying your garden soil with food waste you are feeding the earthly creatures and they reward you with healthy soil. Now where can you get a trade off like that!
Ok so here is how you do it. Get yourself a fairly large Tupperware bowl. One large enough to hold at least a week’s worth of food scraps. Then after each meal dump everything and anything into that bowl. Just do not put steak bones in there, they wont biodegrade or be eaten by the worms. Banana peels, apple peels, coffee grinds, fish, vegetable scraps, egg shells and basically anything you don’t eat, all qualifies.
When your Tupperware bowl gets full, take it out to your garden and dig a hole about a foot to two feet deep and then dump the food scraps into the hole. Fill in the hole with the dirt and mark the spot with a stick or something else so that you do not dig up that area again for another three months. You need to give those little rascals some time to eat it all.
Now you simply repeat this process as the Tupperware bowl gets full. If you find that you live in colder climates where the ground may freeze for lengthy periods of time, then consider starting a warm box to recycle your food scraps. That goes beyond the scope of this article but I am sure if you Googled the search term “vermicompost” you will get all the information you will ever need.
So what are the two things I was talking about earlier? Well obviously the first is you are adding nutrients to your soil through composting food waste. The second is by composting your food waste you are limiting the amount of garbage that ends up in a landfill. The average four person house hold creates about 8 pounds of food waste per week. If every family in America followed this process we would eliminate nearly one billion pounds of food waste garbage a year. Now that is a lot of trash!
Do your part and compost your food waste. The worms in your garden will love you for it and so will everyone else in the environment.

Earth day is coming soon (4/22/09). This month we have Easter as well…so it got me thinking. How should Christians respond to Earth day?
First, I think we need to keep it all in perspective. Yes, we are to be good stewards of the planet. However, we are not to be earth “worshipers.” The earth is just another thing in our lives that God wants us to be a good steward with. Yes, it is important…However, Jesus Christ and His shed Blood is much more important. Saving souls should be above saving polar bears. You know what I mean?
So, do I think Christian’s should celebrate Earth Day?
Sure. Just make sure you have this whole eco, green planet stuff in perspective. Make sure that you are lined up with the Word and that God is your priority and His will. Do not let being green override sharing the Love of Christ and your true God-given purpose.
All that said, I thought it would be cool to add some fun stuff to do for earth day…
Earth Day Activities:
Plant a tree. This could be a fun family project.
Recycle. Take those cans you have been saving and turn them in.
Make the whole day green. Make eco choices all day long.
Clean up. Take your family to the park and clean up the junk left by others.
Make a point to add more green. Add at least one more green activity to your life.
Go on a nature walk. Enjoy the beautiful environment that God created for you.
Organic. Visit your local Ma and Pa farmer and shop for some earth friendly stuff.

Go Green With Natural Finishes - environmental friendly finishes
Finishes are coatings that are applied to the external and inside surfaces of walls to protect them from the elements and from wear and tear. They also improve the appearance of the structure and are used to enhance the design of rooms.
Petroleum, our main source of oil-based wood finishes and paint, is a non-renewable resource. There are now paints and finishes on the market that are derived from a renewable resource, which in a small way, helps to reduce dependence on oil, and contributes to a more sustainable world.
The basis for these products is whey, which is a product of cheese making, and which has a high biochemical oxygen demand (BOD). This increases the burden on waste treatment facilities, and can also pollute our natural water sources. In the last ten years, this by-product has been used for many new purposes, one of which is natural wood finishes.
When choosing paints for your decorating, use the low or no VOC (volatile organic compound) paints. For hundreds, no, thousands of years, earth, clay and lime have been used, both in hot and cold areas of the world. And now this knowledge is being readapted for contemporary use. If you do any redecorating or new building, it makes sense to contribute to having green, healthy surroundings.
Low and no VOC paints have less smell and less impact on air quality. EPA studies have shown that indoor air quality is up to five times more toxic than outdoors, mainly because of toxic emissions from paint and finishes. This particularly affects anyone with allergies, asthma, or chemical sensitivities. With the new “green” paints, there will be lower contamination of landfills, groundwater, and the ozone.
Switching will not cost you more. Cleanup is easily done with soap and water, instead of toxic chemicals, and brushes can easily be cleaned and reused. The paint is still washable, and is far less harmful to you, your pets, and the environment.

We’ve all read the stories about how municipal water systems in the United States are contaminated with toxins such as lead, mercury, copper and even bacteria. In some parts of the country, stories of raw sewage leaks into fresh water supplies have made the news. And, people have reacted by drinking expensive bottled water as a supposedly healthier alternative to ordinary, inexpensive tap water.
City Water Supplies Are Safe
Of course, the truth about the safety of the nation’s municipal water supplies has finally come forth - drinking water from household taps virtually anywhere in the country is safe, pure and incredibly inexpensive. And, we’re learning that bottled water isn’t as healthy for us as we first thought.
Get Off The Bottle
First there’s the plastic container, or bottle itself. That convenient, plastic water bottle we’ve gotten used to carrying around is made from plastic material that contains cancer-producing toxins called phthalates. These toxins actually leach into the water in the plastic bottle and accumulate in our bloodstreams. Studies show that the concentrations of phthalates in our systems are increasing with each generation, mainly as a result of drinking water bottled in toxic plastic containers.
Plastic is Hardly Boidegradable
These plastic bottles aren’t biodegradable. Plastic throw-aways now represent at least 25% of the contents of our landfills. And plastics won’t break down for around 10,000 years - some plastics can take even longer to degrade. So our healthy-water myth has turned into a big health hazard. What can people do?
A Nice and Effective Alternative
Fortunately, there are many easy and inexpensive alternatives to our drinking water challenges.You can easily install a simple charcoal-type filter system on your kitchen faucet. These inexpensive filters can remove up to 99.9% of heavy metals and other toxins that may (or mostly may not) be present in your city’s drinking water. And you can now buy a portable water filtration system that’s as convenient as your old plastic sports bottle, but the bottle is not made of toxic materials.
Cheap Filter Removes Most Contaminants
The filters that can be attached to your kitchen faucet are cheap (generally under $50) can be found at most hardware stores, reduce chlorine and heavy metals, and generally make your tap water taste better. For example, the Brita system costs about $20 - 40 for a starter set, and $20 for each replacement filter. It will filter about 100 gallons of drinking water and lasts for about 4 months.
Portable Filtration is the “Wave” of The Future
For about the same price, you can now get a 16 ounce portable water filtration system from Back to the Tap, which actually filters as you drink. It uses a number 4 LDPE plastic bottle, which is the kind of plastic that doesn’t normally leach phthalates. The filters are replaceable, and you can refill anywhere with plain tap water. It can be refilled about 300 times, and that’s 300 disposable plastic bottles you’re not throwing into already full landfills.
Going green does take some conscious thought and careful planning, but it’s getting easier every day to go green. In this case, you will be rewarded with better health and less plastic in landfills - and more money in your wallet. Remember - bottled water costs MUCH more than gasoline, per gallon. So, save your health and the environment and tons of cash - by drinking water from your own household tap!
There’s no reason to poison your family and spend thousands of dollars just to have a clean home. Clean your house with simple and pure natural cleaners - and save enough money for a really nice vacation! Want to find out how to go green, save money and save Planet Earth?

Clean Green Computing
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.
