Time to use Amazon like they used to use brick-and-mortar book stores!
Find a cool product on Amazon?

That company exists OFF Amazon, too.

1. Google company name
2. Order from their site
2a. Can usually find a 10% code!
3. Can still get product in 2 - 8 days.
4. Company avoids losing 25% margin share to Amazon.
5. You avoid giving money to Bezos.

I’ve been publishing a magazine on how to make buildings sustainable since 2003. I’m terrible at social media - it doesn’t come naturally to me - but I have a few ideas that might help. First, we need to clearly define what we do and don’t mean by sustainable. Confusion erodes confidence. 1)

We need more Passivhaus Designers and Tradespeople. So pleased that another group of amazing people found success and passed their Passivhaus exam with flying colours.

If you’d like to know how you design buildings that close performance gaps and improve comfort why not come to the Thermal Bypass Workshop I’m delivering next week. www.greenregister.org.uk/events/event...

According to Sotheby's Real Estate, the hot design trend of 2024 is comfort, and the superrich are looking for "comfort, ease, and quiet luxury." But research shows that you get true comfort from warm walls, good windows, and fresh air, which is what you get from #passivhaus.

The superrich apparently are looking for "comfort, ease, and quiet luxury." Passivhaus delivers.

In a Christmas special of the Zero Ambitions podcast, we interview authors Lenny Antonelli and Andrew Simmonds about how Mass Timber is wonderful, but we have to use it carefully, thinking of simplicity, sufficiency, circularity and efficiency.

Good to re-visit Stewart Brand's 'How buildings learn' What happens to buildings after they're built. Do architects care about people or do they only care about their 'art'? www.youtube.com/watch?v=maTk...
