Well, a lot of people assume that landscaping because it's with plants means that it's naturally green and environmentally friendly, but that's not true. There is a lot of plants that people use in the landscape that are very hard to grow here and they require a lot of work, pesticides, they require a lot of fertilizers and lot of care and water. So what I did here is look for plants that were native to this area, so that they had a natural resistance to disease, to the pest and water requirements.

The patio in the back is a flagstone patio, but it's set in a permeable base and what we did there, it's a natural drainage area for the backyard and we have to figure out what to do with the water but still have a nice usable patio. So what we do, we use some reclaimed concrete, it's called R base which is also environmentally friendly because it's not going into landfill. They crush it, we use that as the base below it and then we set the stone in and planted mondo grass and what that area does, it allows the water from the backyard to run into it and percolate through that down into the soil. It takes any pollutants, any pesticides, fertilizers out and allows the water to go back into the ground water clean.

The irrigation system is called the SmartLine by company called Weathermatic and it is designed to save water and to use water smarter. It's what it does, from the head that were used to the controller and it has a weather station. Now, the weather station allows it to based on your zip code and where you live and weather conditions. Everyday it measures evaporation, what they call, evapotranspiration which is the amount of moisture in the air and so it knows what's going on around your yard.

Sustainability has become a key consideration of manufacturing in recent times - with the intended effect being that anything we make or build, not have a deleterious effect on the health of the planet. Indeed, sustainability is about using resources our in a healthy and environmentally friendly manner and in such a way that provide for the long term needs of our community. Sustainable home building pursues two broad themes: construction using environmentally friendly materials and the most efficient use of energy that is possible.

It should first be pointed out that there is much greater scope for sustainability when building new houses than there is when simply doing a green remodel of an existing dwelling - but that is not to say that there aren't things that any of us can do, irrespective of where we live. Buying more energy efficient appliances, using water conserving showerheads, using aerators in sink faucets and revamping insulation are all within the reach of any home owner. All of these measures save money in the long run by cutting down on our energy and water bills, and because they're utilizing less energy, they're also measures that will see that we're not unduly adding to the planet's stock of greenhouse gases.

Of course, if we're building a house from scratch then we have much greater scope to ensure its sustainability. The two areas that a prospective builder needs to concentrate on when building a sustainable home is energy efficiency and using sustainable harvested eco-friendly materials.

There are a few key areas that we can focus on when building an energy efficient house. The most abundant and cost free energy source we have is sunlight and a good passive solar design will ensure that our house is capturing enough sunlight to be absorbed by the surrounding thermal mass, which will then release heat back into the room when the sun goes down. The utility of this design is dependent on also having good insulation. The sun can also be used to generate a large portion (if not all) of our heating and electricity needs. By placing solar panels on the roof we can convert sunlight into electricity to heat water and power domestic appliances. Advances in solar technology are rapidly seeing solar power become a more cost effective way of generating power. These measures will all be complemented by making sure that all your electrical appliances are energy efficient.

Consideration should also be given to how water will be used in your home. Using low water capacity toilets and flow restricted shower heads are practices that are now actually quite common. This theme can be extended by diverting gray water from clothes washing and bathing facilities to watering plants, and by catching rain water from roofs for use inside the house. Concentrating your landscaping on indigenous drought tolerant plants can also save you an enormous amount of water.

A green builder will also ensure that he is only building with sustainable materials - ideally ones that have been certified as sustainable by the Forest Stewardship Council (FSC)- an independent 3rd party non-biased ratings agency that certifies materials as being sustainable or not; as well using non-toxic paint and finishing products.

The 11th Hour - Environmental Video Documentary

StumbleUpon




"Environmental documentary 11th HOUR resides at the polar opposite of escapist summer fare its mission to firmly confront viewers about the indelible human footprint that humans have left on this planet and the catastrophic effects of environmental neglect and abuse. Produced and narrated by Leonardo DiCaprio and ably directed by Nadia Conners and Leila Conners Peterson the documentary doesn't get much fancier than talking heads news footage and the occasional animated illustration but its message is potent and delivered effectively.The first hour of the film is essentially a horror story recounting the myriad sins perpetrated against the environment (pollution deforestation over-mining resources) the reasons behind it (corporate greed faulty public policy bad leadership ignorance) and what it means for the human race. Thankfully the last third of the movie tilts the mood upward with a spirited discussion of solutions offered by a crack team of scientists designers and thinkers. Stirring visions of alternate energy sources diversified transportation enlightened governmental agendas sustainable homes and cities and most importantly more conscious consumer choices leave viewers with the palpable feeling that change is both necessary and possible. If the "eleventh hour" for our planet is drawing near this admirable film points confidently towards a new dawn."

Sustainable building has been in vogue, ever since the green building concept came into existence. Green building means resource efficient and environmentally conscious, sustainable design which is usually dependent on three areas such as conservation, energy, resource conservation and indoor air quality. You can also identify which properties will save you funds when it comes to fuel costs and making repairs.

Viewed as new-age in construction circles, sustainable design looks at homes holistically, and not just a bunch of unrelated systems thrown together. Natural forms of energy, such as wind, solar, and geo-thermal if available on-site are maximized. Make important decisions between one property and another with enough awareness on how carefully has the construction taken into account the weight of environmental protection. And if you plan to put up additional buildings or extensions to your property, you'll know how to go about it in a responsible way. However, experts are of the opinion that both green building and sustainable building have some difference between them. But, both consider environmental conservation has its prime aim. Viewed as new-age in construction circles, sustainable design looks at homes holistically, and not just a bunch of unrelated systems thrown together.

You must look at the various factors for having a sustainable housing:

Environmental factors: We need to consider the conservation of environment in order to improve the biodiversity and ecology.

Water: rain water reuse, minimising and attenuating surface water run-off to prevent flooding and pollution, make use of water efficient appliances.

Energy: high levels of insulation and reduce energy consumption, make use of energy efficient lighting and appliances, building orientation to maximise solar gains and shelter from prevailing winds.

Materials: make use of materials with longer shelf life, but it should be of lesser environmental impact during extraction, manufacture and us, use of materials which can be reused / recycled, use of locally produced materials to reduce transportation requirements and avoid using non renewable and unsustainable ONES.

Affordability: reduce the cost of ownership - if it isn't affordable - it cannot be sustainable, flexibility and adaptability to meet the changing needs of present and future occupiers.

Transport: Your house should be close to public transport routes, access to amenities and place of work should be easy or have some space to work from home itself, to reduce your commuting problem.

Health and wellbeing: make use of non toxic materials, with adequate day lighting, ventilation provided. Private outdoor space, green space, 'sense of place', integration with the surroundings / landscape.

Today, a good deal more people are more and more aware of the amount of energy they consumed every day and what effect it was having on our planet. If you are among these people and are looking for a way to help out with the environment and cut back on your energy usage, here are six simple steps to assisting you save on the amount of energy you use.
  1. 1. Turn off all of the lights in your home that you are not using, and can you do with less lights? For the next month try to making a genuine commitment to stick to it and compare your current utility bill with next month’s and see how much money you actually could save over the long term just by doing this simple adjustment.

    As a matter of fact your mother likely taught you to turn off the lights when you are not in a room, and mother always right. Even with low wattage bulbs, it can help to make a difference to keep them switched off when you are not using them.

  2. Replace your old thermostat with a digital programmable thermostat if your home does not have one. This way, you can set the thermostat to run the heat or air conditioning less when you are not at home, and then set the temperature to go back to comfortable levels just before you return home. If the system is not running all day it will cut back significantly on the amount of energy you use.

  3. Use solar power whenever you can. If you use outdoor lights, then switch these over to run on solar energy. You can also get a portable solar charger that can charge up small appliances like cell phones and laptops. While people mainly use these devices on the go, you can also routinely use them in the home as well.

  4. Cut down your hot water use. You can achieve this by using warm or even cold water to wash your clothes and hang up your clothes outside to dry, it will smell fresher too.

  5. Be sure all the bulbs in your home have been changed over to the low wattage compact fluorescents. The old style incandescent bulbs can almost triple your energy usage. Also, have outdoor lights with the capability to turn on at night and able to turn themselves off during the daylight hours. This way even if you forget to turn the light off it will not be operating all day.

  6. In the winter months, open your drapes on the sunny side of your house to let the sun in to warm your home, you will be amaze how much energy you could save. And naturally you do the opposite in the summer and close the drapes to keep the sun out.
Simply by utilizing these simple steps and you will be able to cut back on your energy consumption. Not only will you be working to save the environment, but you will also be reducing your utility bills as well.

Interior design is all about creating aesthetically pleasing spaces that are safe, practical and in harmony with the rest of the surroundings. In order to carry this out effectively we must source the best materials, furniture and fixtures and fittings for the job, and in doing so, we inevitably have an impact on the environment albeit inadvertently.

These days with so much emphasis being placed on global climate change, reducing consumption, and recycling, interior design can be a bit daunting if we want to limit our carbon footprint and still get the effect we want. However, armed with the right information, it needn't be a big challenge and we can still create beautiful rooms that are stylish, healthy and that are environmentally friendly too. So where do we begin?

First of all it's important to note that every single thing we buy has an impact on the environment somewhere along the line either, from the way they are extracted, manufactured and processed, or from the distances they have to travel to end up in our home. Take for example paint, wood, glass, metal, textiles and furniture, each of which can have a negative impact if we don't know what to look out for but with a little effort and forethought, we are able to find eco friendly alternatives.

Paint

Conventional paint contains solvents and lot of other harsh chemicals and toxins but it is possible to source paints that have a reduced effect on the environment and that don't contain solvents, which are not only a much healthier option as they won't release harmful gases into your home and the atmosphere, they can be just as effective.

Wood

If possible, try to buy wood that is grown in a local forest so it doesn't have to travel long distances to end up in your home. Also, choose woods that don't have a negative effect on the environment. Look out for the FSC symbol which stands for Forestry Stewardship Council, an international non-profit organization that will ensure that when you buy you will not be contributing to global forest destruction and threatening the livelihoods of people who depend on the forest or timber to survive.

Glass and Metal

Glass and metal are fairly easy to recycle and one of the advantages of both is that in most cases they can be recycled over and over again without losing any quality. Using recycled glass and metal helps reduce the amount of resources needed to produce these materials from scratch, also the process of recycling uses a lot less energy than what is required to make new glass and metal.

Textiles

Textile production can include processes like dying and bleaching which uses a lot of energy and will produce toxic gases which are then released into the environment not to mention the harmful pesticides that are often used whilst growing the raw materials. The main things to consider when choosing an eco friendly option is how renewable the product is, in other words, can it be replenished quickly, whether the product is dyed or if natural dyes are used, and whether a lot of chemicals are required to produce it. Some of the more eco friendly choices include organic cotton, wool and hemp although there are many others available too.

Furniture

How eco friendly your furniture is will depend on the material it is made from, how it is processed and what finishes have been used, so choose carefully. Consider buying second hand furniture or items made from recycled or reclaimed materials and doing them up as this helps to keep existing items in circulation and reduces the amount of perfectly useful items ending up in landfill.

When sourcing eco friendly materials for your interior design project, try to stick to the following guidelines:

- Buy from local producers and suppliers as much as possible as the less distance an item has to travel, the lower the impact on the environment

- Consider the type of materials you choose and whether they come from renewable and sustainable energy sources

- Avoid materials that contain chemical additives or that use a lot of energy during manufacturing processes

- When buying new items, try as much as possible to choose products that can be readily recycled after use or that can be disposed of in an environmentally friendly manner

- Consider low energy or energy saving devices and buy as much as you can from recycled or reclaimed materials

Finally, as a result of the massive amount of publicity given to global warming and the need for conservation of energy, many producers make claims about their products that are misleading or even false so check out the credentials of any suppliers claiming that their products are certified as natural, organic or eco friendly.

With global warming and other environmental concerns increasingly on the minds of Americans, you want to green your home do your part to save the planet. Here are some easy and fun (and cost-effective!) ideas to make your home more environmentally sound.

Chuck the incandescent light bulbs wherever possible. These standard tear-drop shaped bulbs burn out relatively quickly and use up lots of electricity -- creating garbage and using up resources at the same time. Compact florescent light bulbs (a.k.a. CFLs) last many times longer than incandescent bulbs and use a fraction of the energy. They cost more per bulb, but money you save in energy will outweigh the price difference.

Give up on the bottled water. Sure, your Aquafina may taste slightly better than standard tap water, but the cost of bottled water to the environment cannot be underestimated. Bottled water takes energy to procure, distil, transport and package. Instead, buy a top-of-the-line sink filter or just keep a filtered water pitcher in the fridge. Not only will you protect the environment by cutting back on your consumption of plastic, but you will also save a bundle over the long-term on drinking water costs.

Recycle or give away (or sell on the cheap) your old furniture. Instead of trucking your old sofa or 1999 Sony T.V. to the dump, find your used furnishings a second home. You can use online give-away sites like Craigslist to find people in your local area who might want your furniture. You can also sell stuff on e-bay or give it away/sell it at a garage sale. Barring that, you can find an eco-friendly recycling center near you to dispose of your furniture with minimal damage to the environment.

Stock up on natural, organic products. Instead of installing a vinyl shower curtain, for instance, hang up a hemp curtain -- it's equally anti-fungal and does not release small amounts of volatile organic compounds every time you take a shower. Get rid of your harsh kitchen and bathroom cleansers and replace those nasty chemicals (which have been linked to all sorts of ailments and pregnancy-disorders) with safe compounds that won't hurt you, your children, your pets or your environment.

Reduce your dependence on heating and air-conditioning. You can keep a temperate house without paying your local energy company an arm and a leg. Turn off the heat and air-conditioning when you leave for work for the day (or go on vacation). Use your windows and shades to adjust to the weather outside. If it's super hot out, for instance, throw open the windows and turn on some fans. If it's incredibly cold, pull down your shades and keep windows tightly sealed to avoid heat-leakage. You can also invest in thermally efficient windows and sealants to boost your energy efficiency.

Get a professional energy audit. You can find top rated independent energy contractors out there to come to your home and point out precisely where and how you are wasting energy. By following their tips to reduce heat waste, you will not only reduce your consumption of fuel, but you will also pad your pocketbook in the long-term.

Make it a habit to turn off electrical devices when you are not using them. Before you go to sleep at night, go around and turn off the lights, the T.V., the computer, and other appliances, which can drain energy while you sleep. Also, many electronics like DVD players and video consoles stay 'on' even when turned 'off'’, so they continuously consume a small amount of energy – unplug them.

Landscape in an eco-friendly manner. Put out drums to catch rain water to hydrate your plants or garden (if you live in an area that's relatively drought-prone). Landscape with plants that are native to your region and soil type. If you try to keep tropical plants alive in an arid environment, you’ll inevitably use up an unseemly amount of water and natural resources keeping the plants healthy. You might also want to use your garden to grow organic vegetables.

Look for products and services to boost your green mission. You can find expandable foam to seal up drafts in your insulation. You can get screens to put in your windows to block out some of the solar radiation in the summer and thus help you save on air-conditioning costs. You can purchase eco-friendly power strips to reduce your energy bill and general power consumption. You can buy hemp grocery bags to transport your food (and thus save the planet from having to countenance hundreds of plastic and/or paper bags a year).

Get your family and friends into the green act. You can’t do it alone. Teach your family about the value of the environment and establish "rules of the house" to conserve resources and treat your local habitat with respect. Remember that greening your home can be a fun and educational process. Keep up to speed on the latest greening technologies by contacting local environmentally concerned groups or government agencies.

Light-colored roofs made of vinyl are an extremely popular, cost effective, energy-saving alternative to traditional dark-colored roofs on commercial buildings.

How it works:

On a 90° F day, the temperature on a black roof can be as high as 160° F, according to The Heat Island Group at the University of California, Berkeley. Some of that heat is transferred inside to the occupants of the building, resulting in higher utility costs for air conditioning to keep the occupants comfortable.

Light-colored vinyl roofing membranes reduce this problem by reflecting sunlight, bringing temperatures six to eight degrees lower.

According to the California Energy Commission (CEC), cooler roofs reduce peak electricity demand for cooling, improve building comfort, reduce the "heat island" effect and even reduce air pollution. Of course these energy savings also result in cost savings for the consumer or the taxpayer.

Studies by the U.S. Environmental Protection Agency (EPA) and the Florida Solar Energy Center further confirm that reflective roofs made of vinyl membranes or other single-ply materials can reduce utility costs of air-conditioning by as much as 50 percent.

The Proof:

With more than 30 years of documented performance, vinyl roofing membranes have proven to be as structurally sound as other materials, designed to resist wind uplift, structural movement and harsh outdoor elements. An additional benefit: vinyl roofing membranes generally have good fire performance because of the fire-retardant nature of pure vinyl and the addition of flame retardants. Moreover, a draft report from the U.S. Green Building Council's (USGBC) PVC Task Group found that the environmental and health impacts of vinyl building products are comparable to, and could be lower than, those of products made of competing materials.

Vinyl roofing membranes can also be found as a component in urban "green roofs," which consist of a multi-layer soil and drainage system upon which vegetation can grow. Green roofs, in turn, improve the energy efficiency of buildings, enhance the look of urban rooftops and promote healthier air in such areas.

"Available evidence shows that vinyl products can contribute to the environmental performance of sustainable buildings," Vinyl Institute President Tim Burns said. "Whether it is the energy savings provided by vinyl windows or the resource conservation of durable products like pipe, siding and flooring, vinyl has a place in 'green' buildings."

Case Study: San Marcos Unified School District, Calif.

Jim Poltl, director of maintenance and operations for the San Marcos Unified School District in San Marcos, Calif., has installed reflective vinyl roofs on several projects and is now covering 30,000 square feet at three school sites with these roofs.

"This is an excellent design and a good system," he said. His district of about 12,000 pupils started the retrofitting project because the old roofs on single-story manufactured classrooms were leaking. However, once the new system was installed -- complete with improved insulation -- he started hearing comments from teachers who noticed how much cooler and quieter their rooms were. "The money saved on energy costs is really the icing on the cake," Poltl said.

Case Study: University of California, Los Angeles

Greg Zoll, senior superintendent at the University of California, Los Angeles, has also employed several white vinyl membranes on campus rooftops throughout the last five years. He noted that they typically save 20-30 percent in energy costs, with building occupants reporting cooler temperatures that allow them to reduce the energy and costs spent on air conditioning.

"These roofing systems are designed to last 30 years, so multiply that out over the roof’s lifecycle for the true savings,” Zoll said. During peak air-conditioning season, he figures the University saves an average of $800 a month on each of these buildings, or about $10,000 a year in energy costs. “It’s common sense to do this.”
