The IEA-EBC Annex 56 project "Cost-Effective Energy and Carbon Emissions Optimization in Building Renovation" (Annex 56) intends to develop the basics for future standards, which aim at maximizing effects on reducing carbon emissions and primary energy use while taking into account the cost-effectiveness of related measures. Thus, it is necessary to quantify the so-called embodied primary energy and embodied carbon emissions due to the manufacturing, replacement and end-of-life (e.g., disposal or recycling) of construction materials and building integrated technical systems (BITS) added during a building renovation. The increasing building renovation towards nearly zero energy-building standard is expected to lead to a relative increase of embodied energy and embodied carbon emissions. Therefore, it is important to perform a LCA analysis, to involve these notions in the IEA EBC Annex 56 methodology.
