New paper: Review and Analysis of Strategies for Reducing Life Cycle GHG Emissions of Residential Buildings in Humid
Subtropical and Tropical Climates by Daniel Satola et al. 2021 - A Thread (1/9)

We reviewed more than 70 building LCA studies in climate regions common in the Global South, studying building cases from Asia, Oceania, South America and North America. We conduct detailed analyses ...
(2/9)
...based on a final sample of 36 building cases which were fit for harmonization of results. Therein, life cycle GHG emissions show a wide range of 491 to 4811 kgCO2eq/m2. To understand more: First, how structural material choice is influencing emissions...

...we study both embodied and life cycle GHG emission in relation to primary materials used in the building structure. This shows lowest embodied emissions with wood as structural material, and potentially low emissions from use of concrete (non-reinforced). Second,... (4/9)
...we investigate specific design strategies applied in the different cases to analyse their potential for reducing operational and/or embodied GHG emissions. Substantial embodied GHG emissions reduction can be achieved by use of local materials, ... (5/9)
... wood-based structures and extended service life, among other strategies.
Strongest potential for reducing operational emissions is use of photovoltaics, thermal improvement of building envelope, among other strategies. PV shows trade-offs with embodied emissions. (6/9)
Energy and grid electricity mixes have strong influence as well. Find more on energy mixes and other relevant aspects in the paper. Below the full table of building design strategies we investigated and their respective reduction potential. Thanks for your interest!

Thanks to Daniel Satola for inviting me to contribute to this paper and the analysis of cases in his review. We also added the buildings to our larger building LCA dataset and will present further analyses in the future, so stay tuned!✌ (End)

I don't have time to make this detailed, but here's a little thread about the world's first major politically-charged blackout that was blamed on renewables, in South Australia, in 2016............

On September 28, 2016, an unprecedented tropical storm progressed rapidly across South Australia. Truly - this thing was unusual. The sky folded in on itself. It tore towns to bits.


Australia's @climatecouncil pointed out that the storm was so unusual at least partly due to the influence of climate change, and that this is due to get worse.

I'm going to use brief snippets from my book to fill this out! The storm's primary impact on the grid was the destruction of several major transmission lines. When I say destruction - I mean they snapped like twigs.


Here's what happened in the following seconds:

- A voltage spike from the line falls
- Wind turbines automatically shut off due to software settings that trigger shutdown during a spike
- The interconnector to Vic tried to compensate, failed and died
- All of SA blacked out
