It’s inevitable that over a period of time electromechanical systems and equipment become obsolete in its technology or loses efficiency due to wear & tear and poor maintenance. Retrofitting of existing buildings offers significant opportunities for improving its utilities performance, especially with regards to MEP systems. Certain aspects of the retrofitting are improved energy efficiency, increased staff productivity, reduced maintenance costs and better thermal comfort.

The effectiveness of a retrofit project is dependent on various aspects of the building such as geographic location, building type, size, age, occupancy schedule, operation and maintenance, etc., an extensive initial survey is needed to understand the building operational problems and the main concerns of the occupants. The major challenge in such study is availability of as-built drawings and asset lists, especially in older buildings. Managing refurbishments in a live environment poses various unique challenges like safety, partial load shutdowns, construction waste disposal and hygiene maintenance, access issues for the rest of the tenants,noise etc.
