& introduction
A greenhouse (also called a glasshouse) is a building where plants are grown. These structures range in size from small sheds to very large buildings. A miniature greenhouse is known as a cold frame. Is a structure with different types of covering materials, such as a glass or plastic roof and frequently glass or plastic walls
greenhouse purpose #Regulating the temperature #Ensurance of plenty of fresh air to photosynthesize #Good ventilation prevents pest infestations #Encouraging important pollination within the greenhouse
greenhouse effect Global warming, a recent warming of the Earth's surface and lower atmosphere, is believed to be the result of a strengthening of the greenhouse effect mostly due to human-produced increases in atmospheric greenhouse gases.
Basic mechanism The Earth receives energy from the Sun in the form UV, visible, and near IR radiation, most of which passes through the atmosphere without being absorbed. Of the total amount of energy available at the top of the atmosphere (TOA), about 50% is absorbed at the Earth's surface. Because it is warm, the surface radiates far IR thermal radiation that consists of wavelengths that are predominantly much longer than the wavelengths that were absorbed. Most of this thermal radiation is absorbed by the atmosphere and re-radiated both upwards and downwards;that radiated downwards is absorbed by the Earth's surface. This trapping of long-wavelength thermal radiation leads to a higher equilibrium temperature than if the atmosphere were absent.
Role in climate change Strengthening of the greenhouse effect through human activities is known as the enhanced (or anthropogenic) greenhouse effect. This increase in radiative forcing from human activity is attributable mainly to increased atmospheric carbon dioxide levels. CO2 is produced by fossil fuel burning and other activities such as cement production and tropical deforestation. Measurements of CO2 from the Mauna Loa observatory show that concentrations have increased from about 313 ppm in 1960 to about 389 ppm in 2010. The current observed amount of CO2 exceeds the geological record maxima (~300 ppm) from ice core data. The effect of combustion-produced carbon dioxide on the global climate, a special case of the greenhouse effect first described in 1896 by Svante Arrhenius, has also been called the Callendar effect. Because it is a greenhouse gas, elevated CO2 levels contribute to additional absorption and emission of thermal infrared in the atmosphere, which produce net warming. According to the latest Assessment Report from the Intergovernmental Panel on Climate Change, "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations".
A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In the Solar System, the atmospheres of Venus, Mars, and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would be on average about 33 째C (59 째F)colder than at present. Since the beginning of the Industrial revolution, the burning of fossil fuels has contributed to the increase in carbon dioxide in the atmosphere from 280ppm to 390ppm. Unlike other pollutants, carbon dioxide emissions do not result from inefficient combustion: CO2 is a product of ideal, stoichiometric combustion of carbon. The emissions of carbon are directly propor-
Greenhouse effects in Earth's atmosphere In order, the most abundant greenhouse gases in Earth's atmosphere are:
water vapor carbon dioxide methane nitrous oxide ozone chlorofluorocarbons
The contribution to the greenhouse effect by a gas is affected by both the characteristics of the gas and its abundance. For example, on a molecule-for-molecule basis methane is about eighty times stronger greenhouse gas than carbon dioxide,[8] but it is present in much smaller concentrations so that its total contribution is smaller. When these gases are ranked by their contribution to the greenhouse effect, the most important are: Gas Water vapor Carbon dioxide Methane Ozone
Formula H2O CO2 CH4 O3
Contribution(%) 36 – 72 % 9 – 26 % 4–9% 3–7%
During the late 20th century, a scientific consensus has evolved that increasing concentrations of greenhouse gases in the atmosphere are causing a substantial rise in global temperatures and changes to other parts of the climate system, with consequences for the environment and human health.

Soap Bubble Insulated Solar Greenhouse The SolarBubbleBuild is the first operational building of its kind in Europe.
Harvey Rayner My name is Harvey Rayner and I am the author of this site and the owner, builder and designer of the Wrentham Solar Bubble Build. Up until commencing this build in the autumn 2004 my attention has been focused solely on the work I have undertaken as an artist, Contemporary Art And Design By Root2art. Architecture has been a long held passion for me, but my unwillingness to engage in academic study has kept me pursuing an any real investigation into this field. Now having started this project, initially as a practical solution to expanding my wife's rare herb growing business, I have become engrossed in the process of designing, building and developing this technology. Increasingly, I am viewing this work as an inroad towards one day creating pure and functional architectural forms. For me, this new breed of building gets right to the heart of how form can follows function. I believe with this technology as a starting point, unique structures can be derived which reflect the beauty of the inner workings of this truly sustainable building solution.
Bubble Greenhouse Test Cell Design
Diagram Amendment Notes *(Not shown in the diagram below) The end walls could extend a short way down beneath the water level and thus the entire cavity space would be entirely air tight, if not at lease draught tight. *A skirt around the base of the outer skin would be required to complete the weather proofing of the base tank. This skirt would pass from the outer skin to the outside of the tank insulation where it could be fastened using lacing to provide further tension in the skin.
Mobile demonstration module
Bluegreen Future Buildings he display below provides a glimpse of a project being developed by Richard Nelson and myself to produce a mobile demonstration module to be erected at green festivals and other events that focus on sustainable technology. Our initial goal is to have a proof of concept module made by the end of Autumn 2005
Design will be save the world Located in the small town of Mellau in Austria, House Haller was originally built as a structure intended to incorporate and harmonize with the panoramic beauty of the surrounding Alps. The modern home was designed by architects Jürgen Haller and Peter Plattner at the foot of one of Europe’s most famous mountain ranges, and unveils a simple living program with comfortable home and office sensibilities in mind.
The building is built on a slope and features a fortress-like aesthetic, but the lifted design manages to keep the structure from becoming an overbearing mass on the land. Despite its modern look, the house reflects the architectural elements characteristic of the nearby 150-year old farmhouses surrounding the site. Moreover, to better harmonize with the surroundings, inspiration was taken from local tradition, the peaceful village setting and the natural environment. The home maintains several entrances areas found throughout the plan – such as through the double garage doors — but the main entrance is distinct and expansive. A central staircase divides the ground-floor into a living area and a kitchen/dining room. The first floor is made up of bedrooms and an extra bathroom, and the main bathroom keeps a separate terrace with views of the mountain surroundings. The interior walls, ceilings, roof and facades have been constructed with silver fir wood.

Giant Mangrove Patch Office Tower Rotates to Provide Splendid Views of Java Sea The rotating Agung Sedayu Center both mimics and straddles Northern Jakarta's sensitive mangrove ecosystem without leaving an undue footprint. Designed by Agung Mahaputra, Andika Priya Utama, Arief Aditya Putra, Dely Hamzah, Nidia Safiana, and Rahadi Utomo, the Mangrove Tower provides rotating views of the surrounding coastal expanse. On a more practical and ecologicallysensible note, the building's rotation follows the sun as it makes its way across the morning sky. For these and other sustainable features, we give the asymmetrical, mixed-use Mangrove Tower top marks.

Lacy Inflatable Mobile Pavilion Pops Up Like A Circus Tent for Mobilizarte in Brazil Although the winner of the Mobilizarte design competition has already been announced, we're still seeing some intriguing designs pop up (literally) for the mobile pavilion. Mobile Cultural Mobilizarte, a lacy inflatable pavilion, was designed through a collaboration between FRENTES arquitetura and PAX.ARQ. The flexible pavilion can be easily installed to accommodate each site and relies on three elements: scaffolding, prism towers and an inflatable membrane, and upon arrival the pavilion pops up in less than five days just like a circus tent. Everything needed to build the modular pop-up pavilion fits inside two shipping containers.

Finally, the membrane is used to create a covered space over the pavilion grounds. Inspired by two traditional Brazilian elements - the crochet, lace and patchwork quilts – which serve to cover and protect, and the hollow elements (“cobogós”), the membrane is made from inflatable beams and a waterproof and UV layer. During the day sunlight streams in through the translucent membrane and at night lighting shines out through the lacelike pattern. The membrane is raised up onto the scaffolding just like a circus tent is raised and provides a large 550 sq meter space for events. The membrane can be twisted, tilted, tumbled, hung, laid, stretched, twirled or languidly spread to create hundreds of variations for the pavilion. No two installations will ever be alike and the site will determine the size and shape. The pavilion can be attached to other existing buildings to extend their space or it can be set up in an open field or parking lot to act on its own.
