Some of the issues covered:
- Current BRE
projects concerned with sustainability in foundations, the calculation of
embodied energy and re-use of foundations and recycling materials.
- The sustainability
problems facing the foundations industry as the main generator of greenhouse gases
is the production of cement. If the cement content of a foundation could be
reduced a more sustainable system would result. The presentations showed that
the opportunities for the greatest improvement in the sustainability of foundations
came at the planning stage, with less improvement at the design stage, and the
smallest effect at the construction stage.
- How sustainability is
linked to resilience, particularly in resisting the effect of nature, the
client’s view of house foundations, and ground thermal storage solutions for a
more sustainable ‘in use’ foundations.
- The use of thermal piles and smart piles to better enable re-use in the future. Also included was a presentation on the sustainability of steel foundations, particularly when steel can be re-used many times.
