Sustainable Building Materials Revolutionize Construction Industry
The construction industry is undergoing a significant transformation, driven by the need to reduce its environmental footprint. Traditionally, building materials like concrete, steel, and wood have been the norm, but innovative alternatives are emerging to combat the sector’s massive carbon emissions.
Renco: The Earthquake-Resistant, Eco-Friendly Building Block
In Turkey, a businessman named Engin Yesil discovered a super-strong composite material that prevented manhole cover thefts. This inspired him to develop Renco, a sustainable building material consisting of up to 40% repurposed materials, including resin and fiberglass. Renco blocks are lightweight, 100% recyclable, and have 82% less embodied carbon than structural steel. The material has been used to build over 200 earthquake-resistant structures in Turkey and has recently been introduced to the US market.
Waugh Thistleton: Pioneering Sustainable Timber Construction
In the UK, architecture firm Waugh Thistleton has been at the forefront of sustainable building practices. They designed their first cross-laminated timber (CLT) building in 2001 and have since constructed around 30 projects in the UK, Europe, and the US. CLT is a renewable material that can reduce emissions by 19% compared to traditional building materials. Waugh Thistleton’s founder, Andrew Waugh, emphasizes the importance of using sustainably sourced timber and the health benefits of natural materials.
Mareterra: Monaco’s Eco-Friendly Coastal Development
In Monaco, a newly built “eco neighborhood” called Mareterra is setting a new standard for sustainable coastal development. The project features innovative techniques like the “caisson” method, which minimizes marine life disruption, and “eco-reef villages” that provide habitats for marine organisms. Mareterra aims to be a model for responsible coastal city growth, with its eco-measures being monitored for at least a decade.
Industry Shift Towards Sustainability
Experts predict that the construction industry will increasingly adopt sustainable materials and practices. Regulation may be the driving force behind this shift, as governments begin to implement stricter environmental standards. The UK Green Building Council is pushing for more ambitious environmental targets, while Singapore has expanded its Mandatory Energy Improvement regime to include older buildings.
Reducing Embodied Carbon: A Key Focus
Embodied carbon, the emissions released during material production, transportation, and disposal, is a critical area of focus. The US Environmental Protection Agency and construction companies like Skanska USA are developing tools to quantify and reduce embodied carbon. Skanska’s EC3 tool has encouraged suppliers to improve their mixes, resulting in voluntary reductions in embodied carbon.
A Sustainable Future for the Construction Industry
As the industry moves towards more sustainable practices, experts are optimistic about the future. With innovative materials like Renco and CLT, and projects like Mareterra, the construction sector is poised to make a significant impact on reducing greenhouse gas emissions. As Steve Clem, senior vice-president of project planning and sustainability at Skanska USA Building, notes, “The construction industry is doing more for sustainability now than any other time in history.”
