    COM7: Sustainability

Motivation

Sustainability approach is a key conceptual principle to be considered in all human activities including design, production, construction, operation, maintenance, repair and demolition of any building or civil engineering work forming the built environment. The crucial importance of sustainability consideration within all life stages of any concrete structure follows from the amount of produced concrete, resulting in the fact that concrete is the most widely used construction material in the world. Thus, the optimization of concrete structures based on a wide range of sustainability issues represents a challenge and an important contribution to the solution of a global goal focusing to the sustainable development of life on the Earth.

Scope and objective of technical work

The main scope of Commission 7 (COM7) is to develop a strategy as to how to incorporate sustainability issues into the design, construction, operation and demolition of concrete structures. Design concepts of concrete structures should be based on a sustainability framework considering environmental, economic and social aspects. The main focus should be on: the reduction of CO2 emissions from concrete production; the reduction of energy use for construction and the operation of buildings (including thermal mass effect); improving the performance quality of the internal environment (acoustics, thermal well-being, etc.); the reduction of waste to landfill; the development of sustainability metrics and data requirements needed for Environmental Product Declarations and other quality assessment; recycling and use of recycled materials (incl. recycled concrete); resiliency of structures; etc. The goal is to prepare a framework and data for the sustainable design of concrete structures to be implemented in the new fib Model Code MC2020.

  • TG7.1 - Sustainable Concrete - general framework

    Affordability, availability and variability of concrete in connection with strength and durability has made concrete the most used construction material in the world. Use of advanced concrete structures represents important potential in the way towards sustainability of built environment. Concrete and concrete structures should contribute to the development of a sustainably built environment in a socially, environmentally and economically responsible manner.

    Definition of a basic framework of sustainable concrete design and an assessment considering environmental, economic and social aspects. The framework will focus on different types of concrete structures - buildings, bridges, roads, water structures etc. and their construction and operation in various specific regional conditions. The entire life cycle will be considered.

  • TG7.4 - Sustainable civil structures

    The different phases of a civil structure project, from planning to end of service life, demand different methodologies. The phases include the feasibility phase, conceptual design, detailed design, construction, operation and maintenance and end of life/re-use. In the feasibility phase, for instance, different alignments are possible as well as different structural solutions (different tunnel and bridge solutions). The possibility of influencing the construction costs and environmental impact lies mainly in the feasibility phase.

    The objective of the task group is to develop a methodology for optimising the design process leading to lower life cycle cost and more environmentally friendly civil structures. The way of doing this is to apply life cycle costs and life cycle assessment tools in the civil structure design process.

  • TG7.5 - Environmental product declarations (EPD) and equivalent performance of concrete

    The objective of Task Group 7.5 will be two-fold:

    • to recommend preferred approaches (road maps) for establishing "equivalent performance" of low environmental impact concrete typically containing high amounts of supplementary cementitious materials and therefore in terms of composition falls outside the prescriptions found in existing standards/regulations. By equivalent performance is understood that the concrete has acceptable production, structural and durability properties for its intended use. Clear road maps for establishing equivalent performance are a prerequisite and will likely act as a catalyst for increased use of such lower environmental impact concrete compositions to the benefit of the global community.
    • to establish best available technologies for Environmental Product Declarations (EPDs) on concrete compositions (mix designs). EPDs are an emerging means, which, if performed on a common basis, allow a comparison of the environmental impact of different concrete compositions/products. As such, EPDs may be used by the consumer (end-user) to make a qualified decision concerning the choice of concrete, e.g. as requirements to the environmental performance can be verified and therefore also specified.

  • TG7.6 - Resilient structures

    The objective of this task group is to highlight criticalities in current structural design practice and to provide fundamentals to address the design, the maintenance and the retrofit principles towards resilient structures in sustainable urban systems, and more broadly, in view of smart cities.

    TG7.6 aims to develop guidelines to help diverse stakeholders involved within such processes to face resilience issues through a multiscale approach.

    These guidelines will approach resilience issues according to a multiscale approach, starting from the single building scale. Structural design principles are rethought from the point of view of the practicality, reparability, robustness and serviceability in the aftermath of a catastrophe. Particularly, performance goals are recognised to define new resilience-based limit states, in order to enhance disaster preparedness and response of urban structures. Innovative and novel standards and metrics are implemented within the guidelines, as a support to the development of post-event strategic intervention, protection and response technologies and recovery strategies.

  • TG7.7 - Sustainable concrete masonry components and structures

    Current requirements on energy efficiency, building comfort and sustainability have stimulated a growing use of new concrete technologies for construction and retrofit of (i) load-bearing walls in unreinforced, reinforced and confined masonry buildings and (ii) cladding, infill and partition walls in reinforced concrete or steel framed building structures. In that respect, researchers, designers, construction companies and building owners have paid special attention to the use of autoclaved aerated concrete (AAC) and light-weight aggregate concrete (LWAC) with recycled waste aggregates for production of innovative concrete masonry units (CMUs). It is also emphasised that CMUs may be formulated with special aggregates to produce specific colours or textures for finish use.

    The scope and objective of TG7.7 will move in that direction in order to develop a general methodology for construction, design, assessment and retrofit of concrete masonry panels and walls.
