Green Retrofitting of Educational Building for Enhancing the Building's Performance (Retrofitting of IBM building UET Lahore)

The world is experiencing resource depletion and significant energy losses, which have caused an energy crisis in Pakistan. Only if policymakers think that upgrading existing structures may result in a sustainable built environment the challenge of achieving sustainable development in construction in the 21st century be met. In the years between 2003 and 2050, the energy consumption in the building sector will rise by 60% to 90% if nothing is done. Existing structures can be retrofitted to improve their energy efficiency for their useful lives. Retrofitting commonly entails changes to existing structures that could increase energy efficiency or lower energy demand. Retrofits that increase energy efficiency can save operating costs, especially in older buildings, and help draw in tenants and gain a competitive advantage. This study offers some early understanding of the benefits of a building retrofit on a mid-rise higher education building. Site visits, surveys, and stimulation are all methods used to do this thesis work. The model has been stimulated with its existing conditions and compared with the proposed retrofitted techniques. This research finds the impact of retrofitting the existing building envelope and energy-efficient techniques for building services. By providing 4-inch insulation on the south and west walls and 3-inch on the roof with Low-E double glazing on all walls except the east, it can save almost 23% energy. Overall percentage saving by integrated retrofitting techniques has subsequently improved building performance.
