TL;DR: In this paper, two methodological approaches were developed following the modelling principles of attributional and consequential life cycle assessment (LCA) to evaluate life cycle impacts of buildings, integrating climate change (RCP 4.5 and RCP 8.5) and evolution of the energy mix on the long term.

TL;DR: In this paper, the authors evaluated the potential environmental impacts of an energy efficient house attributable to electricity consumption and production by taking into account the temporal variation of the electricity production, and showed that using an annual average mix instead of hourly mix data can lead to underestimation of potential impacts up to 39% for Abiotic Depletion Potential (ADP) and 36% for Global warming potential (GWP) when combining all end-uses.

TL;DR: The results indicate that computers, TV sets and other electronic equipment are of comparable importance in terms of life-cycle greenhouse gas (GHG) emissions.

TL;DR: In this article, the authors proposed two alternative methods to integrate grid-building interaction in life cycle assessment of buildings and districts. And they compared with an annual average method (AA), representative of standard practice, using electric space heating as an illustrative case.

TL;DR: In this article, a methodology to account for such interaction in LCA is presented, which connects three models addressing: market allocation on a national scale over a long term period, short term variation (i.e., seasonal, daily and hourly) of the electricity mix also on national scale, and building energy simulation at the scale of one building.
