DF 71: 71st LCA Discussion Forum

DF 71 — Environmental Benchmarks for buildings: Needs, challenges and solutions

Discussion forum on Life Cycle Assessment
Tuesday, 18 June 2019, ETH Zürich, Alumni (GEP) Pavillon

The Paris agreement requires a significant reduction in greenhouse gas emissions. One of the priority sector is the building stock, as it is an important source of greenhouse gas emissions. COP23, IEA and increasing number of countries are extending their consideration from aspects such as building energy demand and emissions from building operation to building construction and the manufacture of construction materials.

This DF will allow participants to inform themselves on the state of activities and regulations on the environmental LCA of buildings and infrastructure projects in Switzerland, European and other foreign countries.

The day will focus on two aspects:
• environmental benchmarks: How are they derived? What is their level of ambition (checked against, e.g. the Paris Agreement and planetary boundaries)? How much differentiation is needed/offered (new/refurbished buildings, different types of buildings, different climate zones)?
• national assessment methods: The results and learnings of a round robin test are presented in which researchers from different countries assessed an identical building with their national assessment approaches.

This DF profits from the research activities of the IEA EBC Annex 72 “Assessing Life-Cycle Related Environmental Impacts Caused by Buildings”.

This forum is targeted to LCA practitioners and researchers as well as policy makers in the construction sector.
