Retrofitting Existing Building to Improve Sustainability and Energy Performance

1. Retrofitting Existing Building to Improve Sustainability and Energy Performance Retrofitting is the way of changing something after it has been manufactured /developed. Retrofitting in construction or retrofitting a building involves changing its original structure after its initial construction. This method can expand existing facilities for the building’s residents and also helps to improve sustainability and energy performance. As technology develops, retrofitting existing building can significantly decrease energy and water usage.

2. Why Need of Retrofitting Existing Building? Mainly, retrofitting existing building is the more cost-effective solution than building a new structure. Since buildings consume an important amount of energy, particularly for heating and cooling. And because existing buildings involve the largest section of the built environment, it is necessary to start energy conservation retrofits to decrease energy consumption and the cost of heating, cooling, and lighting buildings. But conserving energy is not only the reason of retrofitting existing structures. Benefits of Retrofitting Existing Building •Retrofitted old buildings are more adjustable and appropriate for future activities with more comfort. •Retrofitted buildings are more energy efficient, lower carbon emissions from the building operations. •Decreased Support Costs and Expanded Reliability •Cost saving in long run by decreasing the use of energy as well as water by adopting new technology and equipment’s. •It also helps to increase the comfort level of a building by redesign the interior to enhance end users efficiency and satisfaction through improving interior with comfort. •Lowering the greenhouse production and enhancing the water usage in building; future-proof buildings which means the building will be use and last for many years when it is equipped with current technology.

3. Retrofitting Existing Building is done to expand the survivability functionality. The applications incorporate various sorts of bridges, construction, commercial structures, transport structures in urban surfaces, earth holding structures and marine structures. There are a few systems which are utilized to retrofit structural individuals, for example, segment broadening, outer plate holding, outside post-tensioning, grouting, and fiber fortified polymer composites. In view of the severity of the harm and expected ability to be recovered, an appropriate retrofitting strategy is determined and executed.
