Energy saving for Earth
Categories: energy
Earth day which is celebrate every April 22nd, should not be just an ordinary day. It should changed every people perspective about the earth. Earth is old and required more attention, while pollutions are like infection and making earth ill. Don’t you know that big cities contribute more pollution rather then villages?
Energy saving in cities required Energy management systems which are designed as efficient energy city management. These will will naturally give birth to culture and habits of people in saving energy.
In order to build low consumption of energy city, steps such as transportation planning and traffic management are the most important is to build and provide infrastructure facilities and public transportation / mass efficient and representative. The bigger the scale of a city, you can bet the more the number of people moving within the city each time. With better mass transportation, people are easily reach the distance within minutes and pay less rather than using their own cars, and it will be reducing the number of cars and pollutions on the street.
Instead of transportation, building also contribute numbers of pollution. Each building consume lots of earth resources from soil, water, and many other, which are required efficient design to reduce it. The design of efficient energy buildings can be done in two ways: passively and actively. Passive design is a way of saving energy through passive solar energy utilization, without converting solar energy into electricity. The design relies on the ability of passive over how architects design buildings by themselves able to “anticipate”the problem of climate outside.
In active design, solar energy is converted into electrical energy solar cells, electrical energy is then used to meet the needs of the building. Actively in the design, architects must also simultaneously apply to passive design strategies. Without the application of passive design strategies, energy use in buildings will remain high if the level of thermal and visual comfort should be achieved.
One of the buildings that are considered the most successfully applied those passive and active design technique simultaneously and successful in exploiting the use of solar cells are British pavilions. The building is designed Nicholas Grimshaw & Partners, the architect who also designed the Waterloo International Railway Station which links Britain with France through the undersea route. British Pavilion Expo complex was built in 1992 in the city of Seville, Spain, as a manifestation of the contest which was won in 1989 the architect.
The building is designed with consideration of local climate, the summer air temperature at the Expo was held to reach 45 degrees Celsius, and minimize energy use emits carbon dioxide.
Energy saving could be start from a little things, for example by turning off unnecessary light or any electricity appliances at night.
