The role of steel in reducing operational CO2 emissions in constructions


Between now and 2050, the world’s population will increase by 2 billion people to over 9.5 billion and the share of the population living in cities will increase by 10 percentage points to 68%. These demographic megatrends will continue to underpin the buildings and infrastructure sector and steel demand. Given these megatrends and the support this will require from construction, it is essential to keep in mind that today the operation of buildings accounts for 28% of global CO2 emission.These emissions must be significantly reduced as buildings become net zero operational carbon by 2050.

Steel’s role is at the core of the transition to net zero energy buildings.

Here are four reasons why steel has its place in the transition toward net zero:

  • Energy Efficiency – steel’s role in energy efficiency is its ability to harness and transfer renewable energy. Examples include the steel mountings of roof solar panels, roof- integrated solar heat collectors and geothermal energy piles.
  • Thermal mass – steel can quickly store/release heat when needed. For example, phase change materials (PCMs) can be used in floors, walls or ceilings to capture and store thermal energy, enabling a constant room temperature with less energy demand.
  • Airtightness - steel sandwich panels and windows contribute to maintaining a building’s airtightness, thereby reducing heat losses and contributing to energy savings.
  • Sustainability – steel’s ability to be pre-fabricated in specific dimensions or modules in a factory means that components are made available on-site when needed. The ability for steel to be designed for deconstruction and alternative use implies that the potential to create new future steel is less of a necessity. Being non-organic, steel’s ability to be recycled again and again without loss of quality means there will in the future be less demand for virgin raw materials.

Our esteemed Journal of Steel Structures and Construction is looking forward for the upcoming issue (Volume 6: Issue 1) having journal impact factor of 0.64*. We are glad for the upcoming year issue release as all the authors are invited to submit their recent scientific work through manuscripts in the mode of Research/Case Reports/Case Studies/Reviews/Short Review/ Short Communications/Commentaries/Short Commentaries/Letters to Editor/ Image articles etc., from different regions around the world.

Our Journal welcomes submissions of manuscripts on the topics covering Aerospace Engineering Research, Architectural Designing, Bridges, Buildings, Earthquake Engineering, Interior Designing, Seismic Analysis, Steel Industry, Structural Engineering, etc. In the quality perspective, the journal is determined to maintain an exceptionally high standard in both facts and ethics. Accuracy and authenticity in the scientific reports of present journal are conserved above all nominal needs of the time.

A standard editorial manager system is utilized for manuscript submission, review, editorial processing and tracking which can be securely accessed by the authors, reviewers and editors for monitoring and tracking the article processing. Manuscripts can be uploaded online at Editorial Tracking System or as an email attachment to
