Conclusions
• Concrete based superstructures are the predominant superstructure type in Ireland.
• Traditional based superstructure (concrete block cavity wall) is the cheaper option for building a semi-detached residential building.
• Timber frame based superstructure is the more environmentally friendly from a life cycle non-renewable energy and GHG balance perspective.
