High ambitions: Are tall buildings sustainable?

Are tall buildings environmental foes or allies?

In the quest to make future cities sustainable, tall buildings have been both extensively vilified and expressly commended.

By increasing density, they can reduce urban sprawl and make cities more efficient. At the same time, they are energy guzzlers; it takes massive amounts of power to build, operate, and maintain them.

How, then, do we determine the path forward?

Find out in this very first explainer video by Ecogradia, where our editor-in-chief and sustainable design expert @Nirmal Kishnani explains:

1️⃣ The evolution of tall buildings through time;

2️⃣ How culture has shaped our perception of skyscrapers;

3️⃣ What problems tall buildings can create, and what they can solve;

4️⃣ Radical new experiments in building sustainable skyscrapers;

And much more!

I’m an architecture student my lecture today was about timber framed tall buildings. crazy!

[AleJohMel]

I always thought that the greenest building is one that's already built. Will this always be true (or should I rather ask, is this true) or will we get to a time when it makes ecological sense to build new buildings in place of old ones?

Great video, thank you.

Correction: according to most building and fire codes in North America — any building 8 storeys and above is considered tall — ie. a “high-rise”

Thanks for the breakdown! I need some advice: I have a SafePal wallet with USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How can I transfer them to Binance?
