Can retrofitted buildings outperform new constructions in green standards?

Question

Accepted Answer

Retrofitted Buildings Can Match and Exceed New Constructions in Green Standards

Retrofitted buildings can achieve energy efficiency standards comparable to, and in some cases, surpass those of newly constructed buildings. Hongkong Land's Central portfolio, which comprises older structures, has all achieved the LEED for Existing Buildings: Operations & Maintenance (LEED EBOM) Platinum ranking, demonstrating that significant sustainability gains are possible through upgrading existing structures. This approach avoids the substantial carbon emissions associated with new construction.
Hongkong Land's Central Portfolio Achieves Top Sustainability Credentials

All buildings within Hongkong Land's Central portfolio in Hong Kong have attained the LEED EBOM Platinum certification, a standard recognised by the U.S. Green Building Council. This certification evaluates actual building performance data, not just design specifications. Hongkong Land's Central Portfolio now accounts for 27% of all LEED EBOM Platinum-certified buildings in Hong Kong, underscoring its significant contribution to sustainable building practices in the city.
Retrofitting Enhances Energy Efficiency Significantly

The retrofitting efforts undertaken by Hongkong Land have led to a notable improvement in energy utilisation. The average energy utilisation index for its offices now ranks within the top 15 percentile of Grade-A offices in Hong Kong. Furthermore, for buildings that include both office and retail components, this metric places them within the top 10 percentile, indicating a high level of operational efficiency achieved through upgrades.
Older Buildings Demonstrate High Performance

Remarkably, older buildings within the portfolio are among the highest performers. Jardine House, originally completed in 1973, is highlighted as the top-performing building within Hongkong Land's Central Portfolio. Its excellence spans across key environmental metrics, including water efficiency, energy efficiency, indoor air quality, and waste diversion, proving that age is not a barrier to achieving superior green building standards.
