What would a good city look like? To make a better city, planners aimed at creating a city in which the insalubrious environment and social structure would be defeated by a reordering of physical and social arrangements, so that all the citizens could attain the benefits of beauty, community, and democracy. In Harvey's opinion, the better city should confront on the postmodernist challenge to political economy, and deal with environmental sustainable. However I think green buildings could make good cities, and also citizens will have a best quality of life. According to the World Green Building Council's definition, “to significantly reduce or eliminate the negative impact of buildings on the environment and on the building occupants, green building design and construction practices address: sustainable site planning, safeguarding water and water efficiency, energy efficiency, conservation of materials and resources, and indoor environmental quality.”The green building, which is sustainable in the built environment, can reduce environmental impact but also provide better buildings. The technologies associated with green buildings include: -Energy conservation -Water conservation -Material selection -Use of renewable materials -Occupant health and indoor environment quality -Site ecology -Recycling The green building can be residential, commercial, retail and industrial buildings. For example, the green building uses water-mining plant to recycle water on toilet flushing, watering the garden, and washing cars. The building also uses phase-change materials for cooling, automatic night-purge windows, wavy concrete ceilings, which saves a lot of money and become more sustainable. The idea of green and healthy cities is becoming more important nowadays. The better city should be planed for health and well-being by planners, and they will mainly focus on service facilities, educations. The good city will also need to be safe in community, and make community more walkable, and has an urban design with exquisite streetscape. However the planner keeps developing new ideas of how cities should be changed, therefore the city will become more livable and sustainable in the future. Reference: Susan S.

Wilkinson (Oct, 2006) Green building-issues for the valuation process, Uiversity of Melbourne-----------------------The ascendancy of the Net economy As we cross the threshold into the next century, human society is beginning its move from the industrial economy into the knowledge-based economy. The general trend is that the 21st century will be a new era of the knowledge-based economy. As mentioned in my previous article, the most notable characteristics of this new era of the knowledge-based economy is information-driven economic growth and globalisation. This article will deal with the information aspects of the knowledge-based economy. In more specific terms, the application of information to the economy is best exemplified in the networking of communication, or the so-called Net economy. This Net refers to the computer network of satellites, optic fibres, cables and telephone lines that connect the whole world. With the click of a mouse, information from the other end of the globe will be transported to your computer screen at the dizzying speed of seven-and-a-half times around the earth per second. Singapore has an early start in networking. If we deposit a sum of money at a particular POSB branch, we can withdraw our money from any other POSB branches in Singapore. This was an early step in networking. The networks of the future would have greater significance and implications. Generally, there are two aspects of the Net. One is the networking between businesses and their customers. The other is the networking between individual businesses, or the regional and even global networking between industrial production and scientific research. The examples of the POSB and Internet shopping belong to the first aspect. From a long-term perspective, Internet shopping is but a low-level aspect of the Net, and it is not likely to become the most important trend. After all, most merchandise are unsuitable for Internet shopping. Besides, if everyone shops on the Net, what will happen to our Orchard Road? Or New York's Broadway? A friend said if he were to force his daughter to shop on the Net instead of letting her shop at Orchard Road, the daughter would rather kill herself. Therefore, the second aspect of the Net will be more important. Its significance goes beyond ...
