Read more about this EPD document
Declared Unit: 1m² of concrete cladding panel, single leaf 150mm with acid etched face. Includes insulation and plasterboard
The declared product is a 1m² of concrete cladding panel single leaf 150mm with acid etched face. Including rebar consisting of two layers of B503 mesh. Stainless steel fixings consisting of two restraints and two dowels per panel. The declared unit includes insulation and plasterboard. Precast concrete is made of cement, aggregates, water, and (if needed) admixtures.
The concrete mix agreed by the association technical committee is designed to be representative of average UK products.

This is an association declaration which uses average data from member companies of British Precast Architectural and Structural. It is based on data covering a period of 12 months (From January to December 2015).
The type of EPD is Cradle to Gate with all options declared - this equates to a cradle to grave EPD without the inclusion of module D. The modules considered in the Life Cycle Assessment are modules A1-C4 inclusive.
The most widely studied indicator in an EPD is the Global Warming Potential (GWP) which most people would understand as the carbon footprint. The breakdown of the GWP impact for this product across the cradle to grave assessment is show below:
Interrogation of the LCA results show that the cradle-to-grave GWP (Global Warming Potential) impact of 1m² of precast concrete cladding is 105.7 kgCO2e (Modules A1-C4).
For GWP, A1-A3 accounts for 101% of the lifecycle impact with carbonation in the use phase and post-demolition, reducing the overall impact of the cladding panel. Carbonation in the post crushing phase of the end of life reduces the GWP cradle to grave impact by 5.9%.
