Importance Of Embodied Energy In Construction

Understanding embodied energy The construction industry needs a huge amount of material for projects, such as concrete, timber, steels, water and minerals. It takes a significant amount of energy to extract and transport raw materials, change the materials into a useful product, and then transport the product to the required site or supplier. While these activities are indispensible need for human development, they also tax natural systems at all margins- local, regional, global. This extraction of resources and consumption of energy causes release of toxic pollutants into atmosphere. All these emissions are accounted to be embodied in the final processed material. To put it simply embodied energy is the total energy consumed during resource…show more content…
40% of the total global energy is consumed by buildings, as embodied energy during the construction phase and as operation energy during operation phase. Embodied energy includes a list of processes including building material production, on site delivery, construction and assembly on site, renovation and final demolition. Recent studies done by different agencies have considered the significance of embodied energy inherent in building materials. The initial embodied energy of various materials, components and systems can vary between projects, depending on suppliers, construction methods, site location and the seasonality of the work. Since tough Building Regulations and improvements in construction standards, new buildings are becoming more and more energy efficient. Use of low and zero carbon energy supply on-site like PV panels and solar thermal hot water systems helps in reduction of operational carbon emissions associated with new buildings. Therefore, in terms of the total whole-life carbon footprint, the embodied energy and carbon emissions are becoming much more important in relative…show more content…
Geoff hammond & Craig Jones. This project was developed in Bath University to create an inventory of embodied energy and carbon coefficients for building materials. The data processed for developing it into reference material has been collected from secondary resources in the public domain, including journal articles, life cycle assessments, books, conference papers etc. Ref.
