Special Issue Information

Dear Colleagues,

You are already well aware that building energy optimization and sustainable development are on the same track. The building sector highly affects the critical issues of our generation, such as climate change, energy poverty, and the economic crisis. In most countries around the world, it is responsible for around 30–40% of energy consumption, with a similar share linked to greenhouse gas emissions. Therefore, the optimization of building energy design and retrofit is a “must” to promote sustainability. Indeed, such an achievement would yield substantial reductions of energy consumption, running costs, polluting emissions, other than improved indoor environmental quality. In this regard, a great deal of attention should be addressed to the energy retrofit of existing buildings, the turnover rate of the existing stock being very low (around 1%) in most countries, especially in developed ones. Finally, the words “sustainable”, “building”, “retrofit”, “energy”, and “optimization” (forming the SI title) provide concepts that need to be coupled to achieve a better life for us and our children.

In this frame, this Special Issue aims to propose a collection of worthy studies that combine the aforementioned concepts dealing with:

  • methodologies and/or case studies concerning sustainable building retrofit;
  • methodologies and/or case studies concerning the optimization of building energy retrofit;
  • methodologies and/or case studies concerning the energy retrofit of entire building stocks;
  • methodologies and/or case studies concerning the analysis and optimization of energy policies that drive building retrofit;
  • numerical/experimental studies addressing the investigation of innovative envelope components or energy systems for building retrofit.

Original papers related to the above topics and also dealing generally with methodologies, numerical and experimental investigations, case-studies addressing building retrofit are welcome.

Thank you for your contributions.

For concrete columns damaged by fire, a strengthen technique using thin-walled steel tubes is proposed. To investigate the axial compression capacity of post-fire concrete columns strengthened using thin-walled steel tubes, considering tube thickness, the strengthening method, and section geometry, 12 specimens were fabricated, of which two were control columns and 10 were exposed to fire in accordance with the ISO834 temperature curve. Subsequently, eight specimens were strengthened. Axial compression tests were conducted to provide a better understanding of the strengthening technique. The experiments indicated that: (1) Different failure modes were observed for different cross section geometry—local bucking for square sections, and shear failure for circular sections. (2) The stiffness, axial strength, and ultimate deformation capacity of the enhanced columns may be rehabilitated and even better than the undamaged ones. (3) Two enhancement methods were compared. The steel tubes act as restraints, are merely subjected to tension, and provide strong restraint to the core concrete. The tube carrying load together with the concrete columns are mainly subject to compression, and likely to buckle with longitudinal strain. Finally, axial compressive equations of post-fire reinforced concrete (RC) with thin-wall steel tubes, including both square sections and circle sections, were proposed on the mechanism of concrete filled steel tubes.
