Implementation of sustainable practices in construction sector is not new; this concept has already gained tremendous importance worldwide. It includes many aspects such as environmental, social, economic etc. With the increasing awareness of sustainable development in the construction industry, today’s market is full of innovative green building materials and technologies. The rating systems like LEED are becoming universal so as to measure and verify the sustainable practices employed in the design, construction, and operation of commercial real estate in the world. Despite the increasing adoption of the LEED Rating Systems, the knowledge of how to “green” existing buildings through the implementation of sustainable practices remains largely unfamiliar to the real estate industry. The driving force behind implementing green practices in existing buildings is knowledgeable and diligent. Unlike fulfilling green building requirements for new construction, converting existing buildings into green buildings requires an ongoing commitment to monitor building systems, train staff, and keep up to date with certification requirements. By doing so, we can save up to 30-40% of water, 40-50% energy and 20-40% of construction material. While this may seem like added work with added costs, the financial benefits of pursuing green practices are pronounced and long lasting.
