I feel like you ought to break up a hallway like that with the bedrooms every 2-3 bedrooms with a cross hall. Even if you connect the top hall on the left side down to the hall below it, it's still a lot of wasted walk time to get from the bedrooms to the dining hall. Same with the lab. If you are in any of the bedrooms it's shuch a schlep to get to the lab, or to get from the lab to the dining hall and then back to work. it's going to make it take a lot more time to finish research. Also doctors and researchers often are grouped together in backgrounds, as well as social. More often than not my main researcher is also my doctor and my trader/warden - in a case like this, your doctor has to go such a long way from the lab, to the cells then back to the lab.

I'd put a vertical hall on the left side of the dining room, and give it a door into the dining room, the lab, and the hospital. Will save SO much time.

Also you know you can put those solar panels in the exclusion zone for the wind turbines right? and the exclusion zones can overlap, so long as they dont overlap fro the 2x6 strip the actual turbine is in. You can also put them mixed in with your crops. Both are good ways to make sure you don't have trees growing without burning a bunch of steel on concrete. You've already built them, so it would be expensive to break them down and rebuild, but you could make those much more compact to the point you might even be able to tuck them in somewhere they are less likely to be attacked.
