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...
(3/9)
...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)

It was a dark and stormy night...

(I’ve always wanted to tweet that) But seriously, there was a tropical storm when a group of people gathered in the woods.

If they were white, we’d call them “founding fathers” but they were slaves who were about to change the world

A thread


Voudou priestess Cecile Fatiman danced with a knife. Then she split a pig and everyone drank the pig’s blood from a wooden bowl while enslaved priest Cutty Boukman prayed:

“The god who created the earth; who created the sun that gives us light. The god who holds up the ocean;

who makes the thunder roar. Our god who has ears to hear. You who are hidden in the clouds, who watch us from where you are. You see all that the white has made us suffer. The white man’s god asks him to commit crimes. But the god within us wants to do good...

It’s He who will direct our arms and bring us the victory. It’s He who will assist us. We all should throw away the image of the white men’s god who is so pitiless. Listen to the voice for liberty that speaks in all our hearts.”

Then , the meeting adjourned & everyone went home.

A week later, on Aug. 21 1791, it began.

In one week, 1800 plantations on the Island of St. Domingue would be burned to the ground and 1,000 white enslavers would be dead.

The shit had finally hit the fan.

THREAD: 12 Things Everyone Should Know About IQ

1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE


2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less.
https://t.co/UqtS1lpw3n


3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)

(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)


4. IQ predicts many important real world outcomes.

For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3


5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)
