Climate Change and Structural Engineers
The sun is the main source of energy to the planet and annually it supplies the earth with certain amount of energy. Some of this energy is reflected back to space directly, but the rest that enters the planets is either absorbed by the atmosphere and earth surface or reflected back to space. However some of the energy is trapped by the atmosphere to warm the earth’s surface in a natural way. This phenomenon is called the ‘The Greenhouse Effect’ which is caused by certain gases in the atmosphere known as ‘Greenhouse Gases’, such as Carbon Dioxide (CO2) and Methane (CH4). These gases reflect energy back to earth not allowing its escape to space. However, if the concertation of the Greenhouse Gases in the

After analysing the surrounding environment of the construction area, structural engineer start to develop a concept design with the aid of other experts such as architects and construction engineers. They take all the important aspects such choice of material choice, ventilation and illumination into consideration. As well as they use their knowledge about how forces interact and what behaviour must be expected from different substances to come up with the brightest ideas and solutions for a structure to be able to sustain itself through standard predicted conditions. Finally ending with a technical design before …show more content…
Insulation chosen must by of high R-value, thus having better thermal resistance. But at the same time to be of an adequate price and comforting availability for convenience. In addition to that, instead of using conventional heating system, heat pumps can be implemented since they are very efficient. Heat pumps operate with the same concept of a refrigerator but just reversed, as they remove heat from elsewhere source such as the underground and transfer it to the building (illustrated in figure 2). If the building is well insulated, has a very efficient temperature regulating system, uses excelling efficient lighting methods and has a small average temperature difference with it surrounding it achieves its least consumption of electricity thus emits less carbon dioxide. Structural engineers can go even further by trying to achieve a structure with zero carbon emissions by implementing concepts such as natural ventilation (illustrated in figure 3) in warm regions. Natural ventilation will decrease the rate of air-condition systems usage which is still rising from the 1940’s, and will contribute highly over a large scale to climate change since an air-conditioned building produces about 75 kg of CO2/metre square/year. However, when it comes to natural ventilation structural engineers must think about the building’s orientation and study wind

    Greenhouse Effect and Global Warming The greenhouse effect is the exchange of incoming and outgoing radiation that warms the earth. This occurs when the suns energy reaches the earth and its reflected back to space and the rest is absorbed. Global Warming is the gradual heating of earths surface, oceans and atmosphere. What causes greenhouse effect and global warming, is it harmful to humans, and what can we do to help it, can it be reversed? Greenhouse gases are natural gases, like methane, carbon dioxide, and water vapor.…

    The Earth’s atmosphere and clouds absorb this infrared energy and radiation directed from the Sun by greenhouse gases. Some examples of greenhouse gases are carbon dioxide, methane, and water vapour. Then, these gases emit the energy back in every direction, in which some reach back to Earth to warm it even more. The greenhouse gases…

    This radiation can be dangerous to human health in large quantities, causing sunburn and skin cancers. Ozone (O3), another greenhouse gas, protects life on the surface by absorbing most of the damaging ultraviolet radiation from the sun. In order to maintain a radiative equilibrium, an equal amount of long wave radiation is released back into space. However, due to greenhouse gasses, not all of the terrestrial radiation makes it directly back to space. Greenhouse gasses are unique in that they are transparent to solar radiation, but absorb terrestrial radiation.…

    The ideal relative humidity is between 30 and 50 percent, for optimal comfort. The consistent airflow provides improved air filtration and improved air quality. • Energy Efficiency: Variable-speed motors consume less energy than conventional motors. For example, the variable speed motor uses approximately one-eighth the amount of electricity used for a conventional single-speed fan motor when it operates at half speed. Consequently, the variable speed motor can outlast a conventional motor, reducing the incidence, and costs of heating and air conditioning repair in Dallas.…

    The greenhouse effect is a naturally occurring process within our atmosphere, it aids in heating the earths surface and atmosphere. The greenhouse affect is caused by the fact that certain atmospheric gases, gases such as carbon dioxide, water vapour and methane are able to change the energy balance of the planet by absorbing long wave radiation emitted from earth’s surface. Without the greenhouse affect our earth would be a chilly -18°C in comparison to the present average temperature of 15°C. As energy passes through the atmosphere a number of different changes take place. 26% precent of the suns energy is radiated back into space by clouds and other atmospheric partials.…

    According to ucsusa.org, “Global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars. Carbon dioxide spreads around the planet like a blanket, and is one of the main gases responsible for the absorption of infrared radiation (felt as heat), which comprises the bulk of solar energy.” This quote is evidence of how the hole in the ozone layer allows UV rays to be wrapped around the Earth causing the warming of the…

    According to the U.S. Environmental Protection Agency, Earth 's temperature depends on the balance between energy entering and leaving the planet’s system. That means that when the energy from the sun is absorbed by The Earth, the planet warms while when the sun’s energy is reflected back the Earth cools. b) Volcanoes: emission of gasses after…

    The Sun, the closest star to Earth, and a life-sustaining necessity. It is also the center of space and solar weather, which powers and affects much of the solar system’s activities and life on Earth. Space weather goes hand in hand with the Sun’s constant gaseous activities, which depend on the Sun’s natural occurrences. This paper discusses the important topics of solar plasma, solar wind, as well as solar flares and coronal mass ejections. It also looks at human abilities to capture and use solar wind energy to further space exploration and travel in more efficient techniques and methods.…

    For all of the sunlight that earth absorbs, an equal amount of infrared radiation must travel from the earth back to space. If this process did not happen, there would be no global warming or global cooling in the atmosphere. The greenhouse effect refers to short wavelengths of the visible light spectrum, from the sun, to pass through a transparent medium, but longer wavelengths such as infrared radiations are not able to pass. Infrared radiation plays a major role in global warming. Global warming is produced by the trapping of the rays in earth’s atmosphere by the rising of carbon dioxide, which causes the excessive heating.…

    Silica shall be used to ensure that the water does not coalesce and thus remain in tiny droplets. This shall serve to increase the surface area of water that comes into contact with the methane gas, thus speeding up the rate of absorption of the gas. The “dry water” soaks up the gas quickly at the water’s normal freezing point; instead of having to go to the -113 degrees Celsius (or be under a pressure of up to 5000 kilopascals) required to maintain the gas in liquid form. This is way cheaper as it requires lesser energy consumption. The costs involved excluding the gas itself are quite surprising since mixing the water with silica only requires a normal blending machine – which is locally available.…
