Fun fact: Shade from trees is appreciably cooler than the shadows of structures, because of evapotranspiration.

Trees kick off just a little water vapor from sunlight hitting leaves which works as very light outdoor air conditioning

It’s easy to feel it if you pay attention while passing thru different kinds of shade on a hot day

This is good to know. Yes, trees are ideal for a lot of situations. Beautiful, sustainable, and let the sun through in winter. But for situations, such as a temporary installation, a shade structure might be all that's possible.

Oh sure

I just love evapotranspiration

It’s so cool—both ways

We need a shademaking movement for buildings themselves as well. Seattle architect Mike Eliason explained how "there is effectively no active solar protection industry in North America. Power outages will increase in the future, especially during heat waves. How will building occupants keep cool when they cannot even keep the sun out of their buildings? Operable external solar protection offers a level of climate adaptiveness that planners and policymakers need to be thinking about in a warming world." https://www.treehugger.com/buildings-must-adapt-to-climate-crisis-shade-5496660

Our house backs up to a school yard that was a parking lot a few years ago but now a hot spot for lots of families. We are most excited about the tress. We hope they just keep growing and giving more shade to this great community resource, when it's open, of course.

I wonder if anyone has done work on the possibility of planting somewhat more mature trees. I assume that there are biological issues, but substantial construction of people almost always results in a five-year shade gap.
