A mature tree cools the air around it by several degrees. It does this every day, for decades, with no electricity, no maintenance contract, and no expiry date on its warranty.
It also shades the ground beneath it, holds moisture in the soil, cleans what passes through it, and does something for the people who sit under it that no material we specify can quite replicate.
And yet trees are the first thing removed to make room for the building and the last thing considered when we start looking for ways to keep it cool.
We then spend enormous amounts on façade systems, glazing specifications, and shading devices engineered to do a fraction of what the tree was already doing for free.
None of this is an argument against good detailing. We care about façades. But we should be honest about the order of operations.
Before the system, the tree.
Before the certificate, the shade.
The cheapest cooling technology available to us has been standing on the site the whole time.
