Green building

Green building is the practice of increasing the efficiency with which buildings and their

sites use and harvest energy, water, and materials, and reducing building impacts on human health and the environment, ……..

……through better siting, design, construction, operation, maintenance, and removal — the

complete building life cycle.

Green building is also sometimes known as sustainable building or environmental building, although the terms are sometimes defined or

used differently.

A similar concept is natural building, which is usually on a smaller scale and tends to focus

on the use of natural materials that are available locally.

Environmentally Friendly Bamboo House Design..

…. http://materialicious.com/2010/08/environmentally-friendly-bamboo-house-design.html

Bamboo Houses is actually a beautiful scenery that is built

using bamboo solar power arrays capable of producing 9 kilowatts of electricity for the

bedroom and living room blueprints.

As houses with a combination of traditionalism and

modernity, the state-of-the art technology and traditional architecture, they include a humidity and temperature control system, a bamboo

garden and roofed a high level of thermal insulation systems.

Other commonly used terms include sustainable design and green

architecture;

however, while good design is essential to green building, the actual operation,

maintenance, and ultimate disposal or deconstruction of the building also have

very significant effects on buildings' overall environmental impact.

The practice of green building can lead to benefits including reduced operating costs by increasing productivity and using less energy

and water,….. improved public and occupant health due to

improved indoor air quality, and

……. reduced environmental impacts by, for example, lessening storm water runoff and the

heat island effect.

Green building is an essential component of the related concepts of sustainable design, sustainable development and general

sustainability.

Green building is increasingly being governed and driven by standards, such as the

Leadership in Energy and Environmental Design (LEED) rating system developed by

the U.S. Green Building Council.

. Rainwater Harvesting.

http://www.waterrhapsody.co.za/rainwater-harvesting/rainwater-harvesting-faq/

We also make sure that you don’t

unnecessarily install too many rainwater tanks so that these never have enough

roof area and rainfall to fill.

I.e. you draw them as fast as they recharge.

Simply by collecting and using water harvested during the rain season and using this water in your whole household, the tank surges full very rapidly, but you

draw water from the system every time you open a tap, flush the loo, or use the washing machine, or any other use of water.

Practitioners of green building often seek to achieve not only ecological but aesthetic

harmony between a structure and its surrounding natural and built environment.

The appearance and style of sustainable homes and buildings can be nearly indistinguishable

from their less sustainable counterparts.

The environmental impact of buildings

Buildings have a profound effect on the environment, which is why green building practices are so important to reduce and

perhaps one day eliminate those impacts.

In the United States alone, buildings account for:

39 % of total energy use 12 % of total water consumption

68 % of total electricity consumption 38 % of total carbon dioxide emissions

Green building practices

Green building brings together a vast array of practices and techniques to reduce and ultimately eliminate

the impacts of buildings on the environment.

On the aesthetic side of green architecture or sustainable design is the philosophy of designing a building that in harmony with the natural features

and resources surrounding the site. There are several key steps in designing sustainable

buildings: specify 'green' building materials from local sources, reduce loads, optimize systems, and

generate on-site renewable energy.

Building materials typically considered to be 'green' include rapidly renewable plant

materials like bamboo and straw, lumber from forests certified to be sustainably

managed, stone, recycled metal, and other products that are non-toxic, reusable,

renewable, and/or recyclable.

Building materials should be extracted and manufactured locally to the building site to

minimize the energy embedded in their transportation.

Low-impact building materials are used wherever feasible: for example, insulation may be made from

low VOC (volatile organic compound)-emitting materials such as recycled denim, rather than the

insulation materials that may contain carcinogenic or toxic materials such as formaldehyde.

To discourage insect damage, these alternate insulation materials may be treated with boric acid.

Organic or milk-based paints may be used.

Bamboo House Design Catalogs is about catalogs of

bamboo house design.

Dare you to use bamboo as a home material?

Course you will think many times, about the strength

and durability.

Actually bamboo include material that is strong

enough and flexible making it suitable for building

construction materials.

. Quality of the urban green space .

.. http://www.petus.eu.com/left.php?sct=5&sbsct=0&pageid=2&pagesect=0&pagelang=en

The increasing range of "quality"

requirements to the urban green/blue

infrastructure results from the complexity

of functions attributed to them

and the deeper knowledge

continually gained about their capacity to influence different

aspects of both human life and the

urban environment.

.

Architectural salvage and reclaimed materials are used when appropriate as well.

When older buildings are demolished, frequently any good wood is reclaimed, renewed, and

sold as flooring.

Many other parts are reused as well, such as doors, windows, mantels, and hardware, thus

reducing the consumption of new goods.

When new materials are employed, green designers look for materials that are rapidly replenished, such as bamboo, which can be harvested for commercial

use after only 6 years of growth, or cork oak, in which only the outer bark is removed for use, thus

preserving the tree.

When possible, building materials may be gleaned from the site itself;

for example, if a new structure is being constructed in a wooded area, wood from the trees which were cut to make room for the building would be re-used as part

of the building itself.

To minimize the energy loads within and on the structure, it is critical to orient the building to take

advantage of cooling breezes and sunlight.

Daylighting with ample windows will eliminate the need to turn on electric lights during the day (and provide

great views outside too).

Passive Solar can warm a building in the winter - but care needs to be taken to provide shade in the

summer time to prevent overheating. Prevailing breezes and convection currents can

passively cool the building in the summer.

.. A rain garden

http://vienna-wv.com/portal/2013/07/18/what-is-a-a-rain-garden/

A rain garden is a garden which takes advantage of rainfall and stormwater runoff in its design

and plant selection. Usually, it is a small garden

which is designed to withstand the extremes of moisture and concentrations of nutrients, particularly Nitrogen and

Phosphorus, that are found in stormwater runoff.

Rain gardens are sited ideally close to the source of the runoff

and serve to slow the stormwater as it travels downhill, giving the

stormwater more time to infiltrate and less opportunity to

gain momentum and erosive power.

.. James River Basin Partnership

.. http://www.jamesriverbasin.com/pages/rain_garden

James River Basin Partnership began

working on building local rain gardens in 2006.

Since then we have been a part of 26 rain gardens

and counting. Using funds from the Stormwater 319 grant awarded through the

Missouri Department of Natural Resources, we worked with the Ozark Environmental Water

Resource Institute (OEWRI) to study local effects of rain gardens.

Thermal mass stores heat gained during the day and releases it at night minimizing the swings in

temperature. Thermal mass can both heat the building in winter and cool it during the summer.

Insulation is the final step to optimizing the structure. Well-insulated windows, doors, and walls help

reduce energy loss, thereby reducing energy usage.

These design features don't cost much money to construct and significantly reduce the energy needed

to make the building comfortable.

Optimizing the heating and cooling systems through installing energy efficient

machinery, commissioning, and heat recovery is the next step.

Compared to optimizing the passive heating and cooling features through design, the gains made by engineering are relatively

expensive and can add significantly to the projects cost.

However, thoughtful integrated design can reduce costs -- for example, once a building has been designed to

be more energy-efficient, it may be possible to downsize heating, ventilation and air-conditioning (HVAC) equipment, leading to substantial savings.

To further address energy loss hot water heat recycling is used to reduce energy usage for domestic water

heating. Ground source heat pumps are more energy efficient

then other forms of heating and cooling until you factor in the energy lost during generation and

transmission if the project is on the grid.

Finally, onsite generation of renewable energy through solar power, wind power,

hydro power, or biomass can significantly reduce the environmental

impact of the building.

Power generation is the most expensive feature to add to a building.

Good green architecture also reduces waste, of energy, water and materials.

During the construction phase, one goal should be to reduce the amount of material going to

landfills.

Well-designed buildings also help reduce the amount of waste generated by the occupants as well, by providing onsite solutions such as

compost bins to reduce matter going to landfills.

To reduce the impact on wells or water treatment plants, several options exist.

"Greywater", wastewater from sources such as dishwashing or washing machines, can be used for non-potable purposes, e.g., to flush toilets,

water lawns, and wash cars.

Rainwater collectors are used for similar purposes, and some homes use specially designed

rainwater collectors to gather rainwater for all water use, including drinking water.

Green building often emphasizes taking advantage of renewable resources, e.g., using sunlight through passive solar, active solar,

and photovoltaic techniques and using plants and trees through green roofs, rain gardens,

and for reduction of rainwater run-off.

Many other techniques, such as using packed gravel for parking lots instead of concrete or asphalt to enhance replenishment of ground

water, are used as well.
