At Macalloy, we’re proud to be playing our part in the shift towards a more sustainable future for global construction.
We’re delighted to have been involved in a number of building projects across the globe which have been recognised as environmentally-friendly by LEED, the world’s most widely used green building system.
LEED (Leadership in Energy and Environmental Design) certification is a globally-recognised symbol of sustainability achievement and leadership.
LEED-certified buildings are proven to save money, improve efficiency, lower carbon emissions and create healthier places for people. They are a critical part of addressing the climate crisis, meeting ESG goals, enhancing resilience, and supporting more equitable communities.
A 2014 UC Berkeley study found that buildings which have been constructed according to LEED standards, contribute:
- 50% fewer greenhouse gases than conventionally constructed buildings due to water consumption
- 48% fewer greenhouse gases due to solid waste
- 5% fewer greenhouse gases due to transportation
When taken as a whole, LEED-certified buildings across the world represent a huge reduction in energy use and carbon emissions:
- 34% lower CO2 emissions*
- 25% less energy consumed*
- 80 million tons of waste diverted from landfills*
- 25% less energy on average used by LEED buildings compared to other commercial buildings
- 1.3 million tons of coal equivalent saved each year
- 78 million tons of avoided CO2 emissions

Macalloy’s LEED-certified projects include:
Marina Bay Sands, Singapore
Marina Bay Sands resort in Singapore is a major entertainment and business complex. This world-class resort features Singapore’s most iconic hotel, the world’s largest infinity pool and an unparalleled shopping, dining and leisure experience.
Macalloy supplied Tie Rods and Tension Bars to this visually spectacular entertainment and business complex.
The resort features a stunning, outdoor bayfront complex, which has a canopy roof supported by Macalloy tie rods. Our Tension Bars suspend the canopy roof structure from upright steel poles.
Changi Airport, Singapore
Singapore’s iconic Jewel Changi was developed as a landmark destination, to augment Changi Airport’s position as a leading air hub globally and to boost Singapore’s appeal as a stopover destination for travellers.
The result is a stunning mixed-use development with gardens, attractions, retail, dining, a hotel and facilities to support airport operations.
The Canopy Bridge is something of a centrepiece at Jewel Changi. Suspended 23 metres above the ground, with fog emitted at both ends and a glass bottom at the bridge’s centre, passengers can experience what it might feel like to walk among the clouds.
Macalloy supplied a Stainless Steel Tension System, along with a special spherical Duplex Ball, for the suspended pedestrian Canopy Bridge. This allows for movement in the bridge in all directions. Our engineering team designed and engineered the matching nut and seating to go alongside the
tension bars and the ball nut.
Torre Europa, Madrid
The Torre Europa building is in the financial district of Madrid. It has 33 floors, stretches 116m into the city skyline and is one of the tallest buildings in Madrid.
It was built in 1985 but following renovation works between 2015 and 2018 it has become one of the world’s smartest skyscrapers. The renovation incorporated an innovative use of lighting, allowing space and light to be managed more effectively for the people that work in the building.
Macalloy supplied steel tie rods to form part of the reception area roof on the ground floor. The rods support the roof and provide vertical bracing.
The building won a Renovation award of excellence 2019 for Best Tall Building Renovation by the Council on Tall Building and Urban Habitat (CTBUH).
Currently, it is the headquarters of various companies including the law firm Freshfields, the pharmaceutical company Shire, the IATA airline association, and several embassies.
Sustainability is at the heart of Macalloy’s future business strategy, and we hope to be involved in
many more LEED-certified projects in the coming months and years.
