Whilst there is strong international standard guidance on the framework of service life planning-ISO 15686, data to carry out life cycle cost and life cycle embodied carbon calculations is lacking in the standards arena, according to BSI.
The revision of BS 7543:2003 will provide users with a set of default values for service life data, enhancing the robustness of data utilized within models that predict the life cycle cost and the life cycle carbon of building components and materials.
The revision will take into account the emerging CEN/TC/350 European suite of standards for the sustainability of construction works which set out frameworks and calculation methodologies.
The environmental and economic aspects of sustainability rely on service life data.
The draft standard is available for comment until 30 September.
