| Cemex to promote energy efficiency in buildings Mexican cement maker Cemex, in collaboration with the World Business Council for Sustainable Development (WBCSD) and a group of leading companies in the building, equipment, and energy industries, announced the release of "Transforming the Market: Energy Efficiency in Buildings", a new research report of the Energy Efficiency in Buildings (EEB) project." Based on extensive research, the report presents a transformation plan for the building sector and a roadmap for making the required 60% reduction in energy used in buildings in order to meet the global climate change progress called for by the widely recognized Intergovernmental Panel on Climate Change. Buildings currently account for approximately 40% of the world's energy use, more than any other sector, and are a major contributor to climate change. In addition, it is estimated that total energy consumption in buildings will dramatically rise by 2050 along with the increase in the number of people with higher living standards. In order to achieve a more energy-efficient world, a major, coordinated and global effort is crucial to eventually arrive at a point in which buildings produce or recover all the energy they require. The report covers four, key 'sub-sectors' of building types: single-family homes, multi-family homes, offices and retail complexes which collectively account for more than half of all the energy used by buildings. It highlights the need to immediately begin aggressively reducing energy use in new and existing buildings in order to reduce the planet's energy-related carbon footprint and to stabilize CO2 levels. An energy efficient building can use up to 70% less energy than an inefficient one and achieve the same, or even better, comfort levels. This is possible through the combination of efficient design, passive and active measures, energy efficient equipment and materials, and responsible occupant behavior. Cemex has identified a number of ways in which its products can help contribute to more energy efficient buildings. Good building design, coupled with materials like concrete, helps customers to construct buildings that are highly rated for their energy efficiency. In addition, the ability of concrete to store energy (its thermal mass) minimizes temperature fluctuations in a building over the course of the day, reducing the need for additional heating and cooling. Another important benefit of concrete is that its light color reflects rather than absorbs sunlight, helping keep urban areas cool. write your comments about the article :: © 2009 Construction News :: home page |
