Building Materials and CO2 Emissions.
摘要
Life cycle assessment is used to measure total inputs throughout the life of a building and is broken down into a number of stages. Some of the key materials that go into a buildings are cement, steel, concrete blocks, timber, aluminium, plasterboard, insulation and glass. Greenhouse Gas emissions for each of these can be measured in terms of Global Warming Potential and the greatest environmental impact materials can be assessed. For buildings the total life cycle impact can be divided into embodied carbon and operational carbon, this chapter is about embodied carbon.
