Assessment and Analysis of Whether We Are Coming Closer to the Essay

Assessment and Analysis of Whether We Are Coming Closer to the Objectives of Delivering Sustainable Communities - Essay Example This increasing population means that there is a strong need to develop more housing to accommodate the growing population, while maintaining the liveability and usability of the existing infrastructure. However, considering the environmental consequences of creating more buildings, the question of housing is not limited to just making more houses to accommodate people. With the anticipated level of growth, it is essential that the new developments be made such that their impact on the environment can be minimised and environmental sustainability can be built-in from the start. The question of environmental sustainability, then, is not limited to construction of buildings alone, but to creating sustainable communities which also encourage minimal use of personal transportation, minimise pollution, and maximise preservation and regeneration of green areas and other natural resources. The concept of sustainable communities was brought forward in UK in 2003 by then Deputy Prime Minister , Mr John Prescott, through a ?38bn plan for economic, social, and environmental development (OPDM, 2003). He termed sustainable communities as â€Å"places where people want to live, and work, now and in the future†. ... on services and housing caused by economic success, and reforming for delivery by ensuring right legal framework to support the action plan in the agenda. Appendix 1 shows the details of this budget for the different steps proposed in the policy document. This paper analyses the progress made in UK until now on these counts to assess how close UK has come to delivering sustainable communities. One of the key elements of sustainable communities is sustainable construction. The Cambridgeshire County Council has brought forward a guide for good practices on sustainable construction (Land Use Consultants, 2004). This guide illustrates how builders can make buildings that respect the environment and what key parameters builders must take into account in designing and constructing the buildings. These key parameters are: 1) Adapting to climate change: guidelines on ensuring healthy and comfortable environments for living and working through efficient landscaping and reducing the impact of natural disasters on buildings. 2) Energy: guidelines on minimising the amount of energy people need to use to lead their lives comfortably 3) Waste: guidelines on minimising the amount of waste generated and not reused in any way, in both demolition/ construction and occupation of buildings 4) Water: guidelines on encouraging the sustainable use and management of water resources 5) Materials: guidelines on minimising the wider impact of new developments through maximising the use of local, natural and sustainable materials II. Discussion The issue of delivering sustainable communities is systematically considered within the UK government planning, one of the 6 levers identified in the OPDM report of 2003. This is evident from the fact that the Sustainable Communities Act was made a law in

Homework - Assignment Example 5.Go to Earth-Sun in the "to scale" mode. Click to show the masses of each object. At this point the Earths period should be 365 days (if it is not, just hit the reset button). Double the Sun’s mass. What is approximately the new period? Dont forget your units! 8. According to Newtons theory of gravity, if I double the mass of the Sun, by how much should the velocity of the Earth change? How much should the period change?. Does this agree with what you found in question 5? If not, why not? Now imagine that instead of orbiting around an object you are orbiting inside of an object of uniform density (this is possible if you are orbting inside of a thin gas with no drag for example). We will assume the orbit is circular. Newton showed that the only mass that matter for your orbiting motion is the mass inside of the radius you are orbiting as the figure below shows. where V is the volume which goes like the radius cube. The mass inside of a radius r increases as the volume increases. As I move the satellite further away from the center, there is more and more mass inside the orbit. The figure below shows the measured speed of stars (in km/s) orbiting a neighbor galaxy as a function of distance from the center of that galaxy. Kpc stands for kilo parsec and it is an astronomical unit to measure distance. On the figure, we added the image of the galaxy. Amost all the visible matter ends at 4 kilo parsec. Can you explain the graph between 1 kpc and 4 kpc? What do you think is going on between 4 kpc and 6 kpc? Between 4KPC and 6 KPc – Despite an increase in the radius increases the the velocity is increasing. The increase in velocity can be attributed to the fact that the masses of the of the bodies beween 4kpc and 6kpc are
