Introduction Development of the built environment is essential to meet the needs of people and communities. The construction and built environment sector must therefore consider how to strike a balance between these needs and the need to protect the natural environment. Considerations include climate change and global warming, finite resources such as oil and gas, and waste pollution management. We therefore must consider alternative approaches to construction methods and give urgent thought to new ways of providing energy.

Relevance of sustainability What is meant by finite resources? Make a list of as many examples of finite resources you can Edexcel BTEC Level 2 Diploma in Construction

Finite resources The earth has precious finite resources, on its surface and underground including the main fossil fuels we use: oil natural gas Coal Most of our consumer energy relies on these resources to manufacture and provide energy for the goods and services our modern world demands. Fossil fuels are finite and will eventually run out, causing shortages and price rises as the resources dwindle. Edexcel BTEC Level 2 Diploma in Construction

Consequence Watch the video and make a list of all the factors. /environment/global-warming- environment/global-warming-101/ /environment/global-warming- environment/global-warming-101/ global warming melting ice-caps rising sea levels Climate change flooding shortages extinction of species Edexcel BTEC Level 2 Diploma in Construction

Global warming The earth is warming up. Here are some possible reasons that have been put forward: Burning fossil fuels releases CO² which traps heat within the atmosphere. The earth wobbles on its axis, causing North and South to receive more heat from the sun. Edexcel BTEC Level 2 Diploma in Construction

Melting ice-caps Ice in the glaciers and land based ice shelves of Greenland and the Antarctic are melting and receding. The water created flows into the sea, causing a rise in world sea levels. Edexcel BTEC Level 2 Diploma in Construction

Rising sea levels Sea levels are rising slowly. In the UK, it is predicted that the Thames Barrier will only protect London until Edexcel BTEC Level 2 Diploma in Construction To control this, we spend millions of pounds on sea defences every year wales-north-east-wales

Climate change /flooding Our climate is changing, within the last two years; the UK experienced two ‘once in hundred years’ flood, each resulting in huge damage to property. Edexcel BTEC Level 2 Diploma in Construction ogs/wales/posts/floods _and_storms

Extinction of species On August 28, 2007, the new Biodiversity Action Plan (BAP) identified 1,149 species and 65 habitats in the UK that needed conservation and greater protection. The updated list included the: hedgehog house sparrow grass snake garden tiger moth Habitat protection otters bottlenose dolphins red squirrels habitat protection. As species become extinct, the natural order of nature will be upset Edexcel BTEC Level 2 Diploma in Construction

Local and global context If we include sustainability at a local level and in every part of our daily lives Then this will have a profound affect globally. Discuss and share how you embrace sustainability in your own life Edexcel BTEC Level 2 Diploma in Construction

Impact on construction Buildings contribute over 80%, of total CO² emissions As far as construction projects go, sustainability needs to be carefully considered at every stage, from design – construction - use - demolition Those working in each sector need to plan together how to make projects as sustainable as possible throughout the buildings lifecycles.
