Energy Efficiency in Construction

  1. 1. ENERGY EFFICIENCY IN CONSTRUCTION Daniel Lambraia
  2. 2. The energy use in construction has changed over the years. In 1999 the construction industry contributed about 35% of the total CO2 emissions, making it one of the most hazardous industries. With the new effort to reduce CO2 emissions throughout the world and switch to renewable energy sources, the construction industry is following suit.
  3. 3. In the United Kingdom, new goals have been set to reduce energy consumption in general and in buildings more specifically. By 2020, all new buildings will be required to report a statistic of nearly zero energy consumption.
  4. 4. New buildings are not the main concern when it comes to energy use, as they're built with energy efficiency in mind. The focus here is more on renovating existing buildings that are producing high levels of CO2 emissions. Installing new energy saving systems, like newer HVAC systems, can help reduce energy consumption in these older buildings dramatically.
  5. 5. Reducing the emissions from older buildings is only the first enticing part of updating older buildings with new equipment. Another eye-catching figure is that the cost of maintaining these buildings is substantially lower if the building is optimized for energy efficiency.
  6. 6. Construction companies themselves can ensure that their optimizing energy use by keeping their machinery and equipment in good operating condition as well as increasing efforts to reuse and recycle their equipment whenever they can.
  7. 7. A great tool to use to determine how well your building or home scores on energy efficiency is using the home energy score. This test is based on the buildings structure, heating, cooling, and hot water systems. The score will not only tell how energy efficient your building is but it will also recommend where things need to be updated and improved to raise the score.
  8. 8. On top of that, the scale that is used to determine your score will offer estimated savings as your rise through the scale. An example of this would be if your building scored a 5 out of 10, the scale would then show you that if you raised your score just by two points to a 7 that you would be saving close to $4,000 more over the next 10 years.
  9. 9. Many construction companies have begun switching to more plastic based maintenance to improve energy efficiency. The main areas that plastic is being incorporated is in insulation, HVAC, windows, and roofing.
  10. 10. Plastic based insulation improves the thermal performance of a wall while also sealing gaps and leaks. Reportedly, up to 40% of your heating and cooling energy can be lost through leaky HVAC systems. Using plastic materials and sealing tapes can help reduce the leakage, which will improve the efficiency of the systems resulting in lower energy usage and lower overall cost.
  11. 11. Updating your windows with plastic materials that are put over window glass surfaces, you can expect to lower your cooling costs. These plastic covers reflect light instead of absorbing it. Using a similar plastic as the windows, you can lower the amount of heat that is brought in through the roof, which will lower the costs of cooling the building during hot summer months.
