Most experts agree that over the next few decades, the world will undergo potentially dangerous changes in climate, which will have a significant impact on almost every aspect of our environment, economies and societies, and also, the built environment. It is widely known that buildings construction contribute to Climate change. But the main issue is that, how are we going to deal with the direct and indirect impacts of changes in climate on building and construction technology. Construction projects around the world have a significant impact on our environment, both on a local and a global scale. Every stage of the construction process has a measurable environmental impact: the mining processes used to source materials, the transportation of these materials to the building site from sources around the world, the construction process itself and the waste removal and disposal process that follows the completion of the project. With a rapidly developing global economy, it is crucial that we understand how the construction projects we undertake impact the environment and how we can measure and reduce that impact in the future. As the effects of climate change are felt across the world and with the construction industry is responsible for as much as 40 percent of man-made carbon emissions, both governments and individuals are beginning to take the task of building eco friendly houses much more seriously. Fuelled by increased demand a new industry of eco friendly home building has grown up and a whole host of technological innovations have created an arsenal of eco friendly building materials and techniques. From wind turbines, to solar panels, to high efficiency lighting, ultra efficient insulation, glazing, water conservation, plumbing, recycling and much more.
