Maximizing Energy Efficiency Calls For Planning Ahead |

Even before the foundation of a building is laid, a carbon footprint has formed. Much of a carbon footprint can be attributed to energy expenditures related to the transportation and manufacturing processes, which not only add pollution to the environment, but in some cases, additional cost to a project. Picking materials and supplies that were manufactured locally is the first step in aiming to reduce the carbon footprint of a project. Locally produced goods need to travel a shorter distance, thereby using less fuel, allowing for lower emissions and consumption. This may also lead to increased cost savings as the goods must travel a shorter distance saving on labor and fuel costs. The materials chosen to build a project largely affect its overall energy efficiency. For example, aluminum consumes 127 times more energy during its manufacturing process than wood does. Steel requires 24 times more energy. Due to the green building craze, energy efficient materials are now becoming increasingly common, allowing for greater consumer choice. Using the natural features of a property can help greatly reduce energy costs as well as increase aesthetic value. If placed properly, a building may be able to use winds as a cooling mechanism and for natural ventilation. When winter approaches, the wind can be deflected to retain a warmer environment. The position of the building and proper placement of windows can help utilize natural sunlight. Sunlight can help in heating a building during the winter months as well as provide lighting year round. During the summer, shades can help the light from penetrating in a building helping to keep the temperature cool. Properties that feature trees can help do the same in terms of providing shade and other benefits such as protection from winds. Another user of resources is the lawn. Watering it in moderation can help save water yet still provide for vibrant green grass. To save even more water, artificial turf may be an option which requires no watering whatsoever, less maintenance and perfect blades of grass all year long. |
