Webinar: Steel for innovative roofing solutions: information + registration (in German)

Webinar 17 February in German: Steel for innovative roofing solutions

The winners of the SIMI 2021 Grand Prix, sponsored by Groupama Immobilier, were announced on 8 December 2021. One of the prizes, for constructions built between September 2020 and September 2021, was awarded to the new headquarters of Oui Care.  The headquarters, located in Le Mans, France, took the prize in the New Office Building of 10 000 m2 or Greater category.

Care: the key word

Initially, the designers of the project proposed the name ‘Just Care’ for the building, which the project manager imagined as "a headquarters that could best take care of its employees."

The usage of the word ‘care’ “perfectly sums up the vocation of home services - a profession based on people. Oui Care was born of a conviction: a satisfied, happy, and fulfilled employee in his or her job is a 99.9% guarantee of a satisfied customer. As a company, it is our responsibility to take care of our employees and to put them in the best possible conditions to accomplish their mission: to satisfy our customers," says Guillaume Richard, president and founder of Oui Care.

Facts and figures

The new Oui Care headquarters offers its employees 600 offices over 7500 m2, five accessible terraces over 1078 m2, a sports ground, a fitness room, and a weight room in addition to 184 parking spaces and a day care on the ground floor of the building. The site is easily accessible due to its location in the immediate vicinity of the Le Mans TGV rail station, but it also encourages employees to cycle to work thanks to numerous cycle paths. Additionally, the Oui Care headquarters has been designed with an exemplary environmental quality approach.*

Winning the SIMI Grand Prix is a great source of pride for the teams who contributed to the realisation of this project: Oui Care as the project owner and AIA Life Designers as the architect and design office.  ArcelorMittal Europe - Flat Products supplied Granite® Silky Shine steel in Sienna for the facade, which was produced by ArcelorMittal partner Ateliers 3S.

Granite® Silky Shine is a coating system that ensures excellent colour stability over time thanks to its excellent performance in terms of durability, corrosion resistance, and UV resistance.

Conscious of the importance of reducing the carbon footprint in civil engineering by supplying durable products with reduced environmental impacts, ArcelorMittal is looking into the eco-design of its product range of steel sheet piles. In 2019, ArcelorMittal assigned a Belgian engineering firm with the task of designing and comparing technical and financial aspects of three different alternatives to build a 200-metre-long quay wall for a new cruise ship terminal in a Belgian port. The new brochure, Sustainable Ports – Life Cycle Assessment, focusses on the environmental impact of the two most cost-effective solutions resulting from this study and on their Global Warming Potential (GWP).

Port structures: status quo and future needs

Ports have been faced with quite a number of challenges in recent years. On the one hand, sea traffic has steadily increased and modern vessels are getting bigger. On the other hand, our planet is struggling with greenhouse gas emissions. Ports need to expand with new berths being built, but how can we achieve these goals without harming the environment?

Before building a new structure, examining the possibility of extending the service life of existing structures makes sense. This is the best option from an environmental point of view, but older structures typically require retrofitting. Hence, only an economic and environmental analysis can help the owner make an informed decision. When it comes to increasing the dredge level to welcome vessels with higher drafts or when existing structures are close to failure, building a new quay wall may be the sole viable option.

Identifying the most efficient solutions for a modern quay wall

ArcelorMittal appointed Tractebel, an independent Belgian consulting engineering firm, to analyse this multifaceted topic. The engineers proposed focussing on three key indicators: technical, financial, and environmental criteria. Their task consisted of comparing three different technical solutions for those indicators. The selected structure for analysis was a cruise ship terminal capable of accommodating the largest cruise ships. It would be built in a Belgian port, with a draught of 13 m in typical soil and load conditions for a Belgian port.

This brochure focuses on the environmental impact of the two most cost-effective solutions resulting from this study - a steel sheet pile wall and a concrete diaphragm wall - and on their Global Warming Potential (GWP).

Life Cycle Analysis and Global Warming Potential as sustainability indicators

The Life Cycle Analysis (LCA) of the two most cost-efficient solutions was based on the bill of quantities prepared by Tractebel, performed by ArcelorMittal’s R&D department, and peer-reviewed by an independent panel of experts.

The objective was to compare the Total Life Cycle Cost of the steel sheet pile and the concrete diaphragm solutions, including the burdens or benefits of the end-of-life phase (the dismantling and recycling of the building elements without considering reuse).

For this type of application, an LCA is a reasonably fair and transparent method to compare different solutions and suppliers. Although not required by ISO and EN standards, an LCA is more accurate and realistic when it uses specific Environmental Product Declarations (EPD) from the producers rather than generic data from databases.

Construction cost (including design) was chosen as the principal key indicator for the choice of solution. The key environmental indicator analysed in this case was the carbon footprint expressed as the GWP. Its impact for the base scenario is summarised in the graph for a 200-metre-long wall.  This indicator can be included in a scheme to choose the most sustainable solution, referring to the most economically advantageous tender.

The winner is…the EcoSheetPile™ solution!

In this study for the construction of a 200-metre-long quay wall, the steel sheet pile wall made with EcoSheetPile™ (sheet piles produced from 100% recycled steel in an Electric Arc Furnace) offers a 44% lower carbon footprint compared to the diaphragm wall. This corresponds to a saving of 559 tonnes of CO2-eq.

In its quest to further improve the eco-design of steel sheet piles, ArcelorMittal uses renewable energy in the secondary production route (Electric Arc Furnace), thus further reducing the GWP by around 30% (based on the EcoSheetPile™ Plus EPD).

The EcoSheetPile™ Plus range is part of ArcelorMittal's 'XCarb® Recycled and renewably produced' brand.

Sustainable Ports: Life Cycle Assessment

The successful transformation of the steel industry includes zero-emissions steel products being accepted by the end user – and green steel certificates are an important part of this mission.

ArcelorMittal’s partners are key

From ArcelorMittal's point of view, the companies making steel products for end consumers play a central role in reaching this goal. “In the case of ArcelorMittal’s XCarb® green steel certificates, our customers who purchase the certificates can pass the CO2 savings onto their end customer, in line with the Scope 3 accounting approach,” says Jochen Grünewald, Managing Director of ArcelorMittal Commercial DACH.

Bette, a manufacturer of high-quality bathroom elements made of enamelled titanium alloy steel, and OLINT®, a producer of roofing applications under its Rufster brand, are just two of the many ArcelorMittal partners making valuable use of the XCarb® green steel certificates from ArcelorMittal Europe – Flat Products.

Bette makes first XCarb® green steel certificates purchase

The managing director of sanitary supplier Bette, Thilo C. Pahl, is on board with ArcelorMittal’s goals: “We have ordered the first 1000 tons of steel based on XCarb® green steel certificates for our products and see this as a contribution to support ArcelorMittal in the required transformation. In addition, steel produced with a lower carbon footprint fits very well into our own sustainability strategy.”

The shift towards CO2-neutral products is already evident to Bette: "We are currently noticing an increasing interest and demand for green products and our efforts and ambitions in the area of sustainable resource management,” says Thilo C. Pahl.

OLINT® inspires customers to think green with XCarb®

Producing and selling roofing tiles, guttering, and other accessories typically made from organic coated Granite® Quartz and Granite® Ultramat from ArcelorMittal under the Rufster brand, OLINT® passes on the reduction of Scope 3 emissions to their customers.

Their goal is to inspire clients to make environmentally friendly purchasing decisions when buying roofing products. “We want to actively involve customers in an effort to reduce CO2 emissions across the industry,” says Liviu Cusiac, CEO of OLINT®, who have recently purchased XCarb® green steel certificates for 195 tonnes of Granite® pre-painted steel. “Normally this amount of steel would result in just over 400 tonnes of CO2 emissions. All [customers] need to do is place an order for Rufster products made with XCarb® green steel certificates! It’s that simple,” notes Liviu Cusiac.

Plants at Avilés and Gijón now supply higher quality heavy steel plate with a reduced CO2 footprint, allowing customers to buy XCarb® green steel certificates to reduce their Scope 3 emissions.

Responding to the needs of modern offshore wind towers

Following an upgrade in 2020, the No.2 continuous slab caster at Avilés has been running at full capacity, supplying plates for several major offshore wind projects in the UK, France, and the Netherlands. Since September 2021, the caster has produced slabs of up to 2200 mm width, 365 mm thickness, and weighing up to nearly 19 tonnes, broadening ArcelorMittal’s range of plates as a response to the needs of offshore wind tower mast manufacturers.

The 2020 upgrade included the implementation of state-of-the-art technologies such as Dynamic Soft Reduction (DSR) along with new systems to deliver better internal and external steel quality, including less segregation, better homogeneity, and cleaner surface finish.

A commitment to CO2 reduction

As part of its commitment to reduce its CO2 emissions by 35% in 2030 and achieve net-zero in 2050, ArcelorMittal Europe began coke-oven gas injection for Blast Furnace B in Gijón in early 2021. This initiative is reducing CO2 emissions by 125 000 tonnes a year - equivalent to the emissions generated by the annual consumption of 84 000 Spanish households.

Altogether, these investments deliver on European customers’ requirements for greener, high-quality, and heavier plates for civil engineering, wind towers, and offshore structures.

XCarb® green steel certificates

In addition, ArcelorMittal’s heavy plates qualify for XCarb® green steel certificates, which allow customers to report an equivalent reduction in their Scope 3 emissions in accordance with the GHG Protocol for Corporate Accounting & Reporting.

Denis Parein, Commercial Head for Heavy plates at ArcelorMittal Europe – Flat Products, commented: “These investments mean that we can supply heavy plates in the sizes and grades required for the most demanding projects, and with a reduced CO2 footprint”.
