Comparison of Green Architecture with current Architectural Techniques
Any form of design, minimises environmentally destructive impacts by integrating itself with living process.
But our current system of building lacks respect of natural environment as well as for individual people and society as a whole. There is not a single building component used in current construction that can be labelled safe, earth friendly, and low embodied energy. A few materials meet one or two of their criteria, but for the most part the majority of materials fails to meet all three.
Green Architecture is not limited to one material although many materials should be avoided, but encourages the use of materials that are most appropriate for a particular place, climate and program. Green Architecture is also not a style such as post modernism, art deco or gothic.
Many people are beginning to associate certain types of organic forms with Green Architecture thus alternating those people that do not find the so called ‘Style’ appealing.
Green Architecture is a philosophy or movement and an approach to design, not merely an aesthetic exercise. If one has to be successful, Green Architecture must be appealing like classicists, modernists and practitioners of the organic movement alike.
Impact of Green House Gases and its effects
Many chemical compounds found in the earth atmosphere act as Green House Gases. These gases allow sunlight, which is radiated in the visible and ultra violet spectra, to enter the atmosphere unimpeded. When it strikes the earth’s surface, some of the sunlight is reflected as infrared radiation. Green House Gases tend to absorb this infra red radiation as it is reflected back, towards space, trapping the heat in the atmosphere.
Many gases exhibit such ‘Green House’ properties. For example, those that occur naturally in the atmosphere, water vapour, carbon-dioxide, methane and nitrous oxide.
Evidence accumulated by the intergovernmental panel on climatic change which assesses the scientific, technical, and socio economic information regarding climate change indicates that global mean surface or temperature as increased between approximately 0.3 degree Celsius to 0.6 degree Celsius. Since the last 19th century, although there is a considerable uncertainty about whether this temperature increases has been caused by anthropogenic Green House Gas emissions.
The IPCC has concluded that the balance of evidence suggests that there has been a discernible human influence on global climate.
The growth in their concentration is believed to be caused by human activity. In particular, anthropogenic carbon-dioxide emissions have increased dramatically since the beginning of the industrial age due to burning of fossil fuels and deforestation.
