The “building sector” is the major source for demand of energy and the materials that produce by using greenhouse gas emissions. The presence of this gases on the earth contribute to the greenhouse effect, which is produce due to some gases that are part of the atmosphere, which retain the energy the earth produces and they retransmitted back to the earth, causing the world to get cooler and cooler each time. This has a similar effect to a greenhouse and that is the reason why is called like that.
A few months ago, an American architecture firm, located in Chicago announced in the “Evolution of the Skyscraper: New Challenges in a World of Global Warming and Recession,” conference, that they were planning to produce a holistic planning to reduce carbon emissions on the Chicago Loop are, an urban dense core.
Adrian Smith said that the goal of his firm was to “improve the performance of every building and major infrastructure system within Chicago’s Loop. The idea is to reduce the area’s emissions of 3.9 million metric tons of carbon per year, to meet the goals of the 2030 Challenge.” *
Even when the firm is still recollecting data, interviewing building managers in the Chicago Loop area, surveying building areas and improving their database, its idea should be admired by all of us and copied. I mean we should try to create new ways of helping the world, if we don’t want it to end and never reach year 2030.

20 years ago Dubai was only little more than a Middle East desert which had an income only from its oil industry. It had even less possibilities of becoming the most popular state of the United Arab Emirates due to its buildings. In the later 90’s many foreign companies began to move business to Dubai due to this fact it began to concentrate on free trade and tourism to raise its economy. During the next decade many structures were built. To promote their tourist based economy the Dubai government started several large construction projects. Now Dubai has the most luxurious hotel called the Burj Al-Arab which has seven stars, and the Burj Dubai which will be the world’s tallest building.
