An Energy Cabin that is viagra no prescription online cheap truly Energy Smart?


Well, simply, it looks to be the case.

Energy Cabins are self contained heating systems that combine solar energy with wood pellet technology for total central heating for any building.

What looks great is that these are plug-and-play, capable of being part of a new design or back-fitted into existing structures and try it cialis no rx existing heating sytems to radically change a building's energy use.

They are easily connected to any existing heating system (eg radiators, under floor heating etc.) can completely replace traditional boilers.

Next time replacing a heating system, perhaps this should be in line.

Each cabin is fitted with a solar thermal system which can provide you with free hot water for six months of the year. Inside an automated pellet boiler and heat store are fitted which provide central heating all year round and hot water in winter.

What is interesting here -- no shoveling coal at 3 am on a cold winter night.

Interestingly, the Energy Cabin might be best suitable not for the individual home owner but institutions. For example, lets look at a Case study of a hotel in Ireland with 67 rooms:

Before: LPG boilers; over 2 million kwh/year; and over 100,000 pounds annually of levitra online india heating costs.

After: 450 KW capacity wood pellet boilers and 80 m2 of solar panels with a heat pump recovery system; 360 tons/wood pellets/year with a 640 kwh reduction in power use; savings of 45,000 pounds per year giving a seven year payback period with 550 t C02/year reduction in emissions.

Here is a table with claims as to Energy Cabin's financial savings in eight scenarios ranging from a single home to a hospital. For those who expect price lists, Energy Cabin's brochure might be problematic but it does contain a lot of information. It looks to be the type of thing that could be rapidly deployed (along with energy efficiency) to radically change existing infrastructure's CO2 emissions' footprint.
 

Bahrain World Trade Center Getting Its Turbines


I just got a completely unsolicited email from Shaun Killa, the head of Atkins Architecture in Dubai. This, of course, is a fantastically gigantic and important job. Basically, he is in charge of the first ever skyscraper with integrated wind turbines. So I was excited to get the buy cialis now email. Well, I was even more excited to see the contents. Up-close and personal shots of the Bahrain World Trade Center getting its turbines installed.

This really is a massive project. After the jump are some concept and real-life shots. Click on the real-life shots for a large version.
 

A 193-Country-Sponsored Eco-Agreement?


OK, so they're just renovating the UN headquarters. Somehow it's not totally impressive that there's been a plan 10 years in the making to buy levitra online australia get the home of meivending.com the UN up to snuff, but EcoGeek understands how difficult it is to get all those leaders to sign a piece of paper before one of 'em is buy cialis in india deposed or whatever. It's a race against the clock (and, of course, the tumultuous, tangled web we've woven).

From a BusinessWeek article:

The Secretariat building is leaking air through its glass exterior walls, interior structures are riddled with toxic asbestos (although there's allegedly no immediate health risk as it's embedded in the insulation material, this will prove an issue when interiors are ripped up). The heating and http://www.barefootfoundation.com/viagra-injectable cooling systems are erratic, and the good choice cialis side effects entire IT system is outdated.

Wow. And here I was thinking my needlessly wasteful air conditioning situation was going to be a pain to fix.

P.S. How cool would it be if there were a spin-off sculpture like that knotted gun where somebody's tied off an exhaust pipe?

Green Roofs: An Introduction with Pretty Pictures


It's not just for hobbits anymore. The logic of green roofs is becoming more apparent. We can minimize our bills while maximizing the beauty of the urban landscape. And every day it's becoming a little easier to live in a house that just happens to www.ncitech.co.uk have plants growing on it.

Vegetated roofs, or green roofs have a layer of living plants on top of the structure and the waterproofing elements. There are really two types of viagra online sales green roofs, intensive and extensive.

Intensive green roofs often have a soil depth of a foot or more, and require substantial structural elements to support the weight of the whole roof. Intensive roofs can sustain a wide range of plant species and typically require a fair amount of regular maintenance. Because of the additional demands they impose, intensive
roofs are much less common than extensive roofs.

Extensive roofs are much shallower, typically only 2 to 4 inches deep, and are planted with particularly hardy plants. Over the last 50 years or so, this kind of roof has been developed, especially in Europe,. But now they are becoming increasingly common in the United States.

Why are green roofs such a great idea?

First, they help to reduce roof stormwater runoff. In some cases, this can help reduce the size of stormwater pipes, and the amount of stormwater that needs to be treated by municipal water treatment. In a light rainfall, a building with a vegetated roof can have no stormwater runoff at all.

Green roofs also protect the roof membrane from sunlight, which breaks down the roofing material. Having even a couple inches of soil helps to greatly extend the buying levitra online canada life of http://spionline.com.au/online-cialis-cheap the roof, and a longer lifespan means less material ends up in landfills from re-roofing buildings after the membranes have failed.


Green roofs keep the roof cooler, which helps to reduce the heat-island effect, which contributes to cities being hotter than the surrounding countryside. This can be beneficial to the building in reducing its summertime cooling load.

A green roof is also a source of oxygen and provides a habitat for some birds. Birds and insects can find homes much more readily in the living environment of a green roof, where an ordinary roof is nearly barren. And yes, it's even possible to price check 50mg viagra graze goats.



What is a green roof made of?

Starting from the top, an extensive green roof has a layer of plants, which are typically sedums. These are low-growing, shallow rooting, drought tolerant plants. There are many different varieties of sedum, with different different coloration and different flowerings, so that a roof can have a varied appearance, rather than looking like an entire crop of a single variety. The plants are in a growth medium, an engineered mixture of lightweight soils, vermiculite, and other materials that provides a good environment for the sedum.

The shallow depth of the soil aids in keeping weeds from establishing themselves on the roof, since most weeds cannot survive in the arid and shallow soil conditions on a vegetated roof. Local plants that can survive in that environment may establish themselves on the roof, as well. Underneath the soil are several membrane layers, rather than just a single membrane roof. There is also a drainage layer (to allow excess water to move freely, rather than lifting the soil and best price viagra with prescription having it flow off the roof in a mudslide, and a root barrier layer, which keeps the roots from penetrating the order cheapest levitra online roof. The roof membrane sits on cheap buy viagra the roof deck, insulation, or structure of the building much like a conventional roof.


Can I put a green roof on my house?
Green roofs make sense for residential use as much as for commercial buildings. However, retrofitting a green roof onto an existing house is not a simple matter because of http://plaisirdecreer.be/get-viagra-fast the extra weight a vegetated roof adds. Most roofs are not structurally strong enough to support a vegetated roof without some reinforcement. Green roofs also work best on lower slopes. They can be installed on steeper pitched roofs, but the design and installation is more difficult and requires additional care.

The added cost of a vegetated roof versus a conventional shingle roof, and the relatively small number of contractors familiar with installing them are probably the biggest limiting factors. A house with a suitably pitched roof would still likely need structural evaluation from an architect or engineer before going ahead with a retrofit, and some structural reinforcement is likely to be needed.



Does a green roof have to be mowed?

A sedum covered roof is naturally self limiting in size. Most sedums grow only a few inches tall. As mentioned above, it is also fairly self weeding, due to the inhospitable environment it offers to most weed species. An extensive roof planted with prairie grasses on the Ducks Unlimited National Headquarters in Winnipeg, Manitoba uses a controlled burn of its upper roof every three years to viagra propranodol repropogate the prairie plants. The 16 inches of soil protects the building from any damage while the grass fire helps remove weed species and assists prairie species which need periodic fires as part of their life cycle.

What Does the Future Hold?
We were excited a while back to announce Toyota's green roofing tile. These modular, interlockable grass tiles make green roofing an absolute cinch.They're a lot lighter than other methods, and installation is a breeze. At about $34 per tile, they're still expensive, but prices would of course drop if demand were to increase.


And, second, I and many others would like to see Friedenreich Hundertwasser's vision of every horizontal surface being returned to nature:

The true proportions in this world are the viagra no presciption views to the stars and the views down to the surface of the earth. Grass and vegetation in the city should grow on all horizontal spaces - that is to say, wherever rain and snow falls vegetation should grow, on the roads and on the roofs. The horizontal is the domain of propecia mexico nature and follow link cialis india pharmacy wherever vegetation grows on click now generic cialis without prescription the horizontal level man is off limits; he should not interfere. I mean taking away territories from nature, which human beings have always done.
