Numbers are wrong, but principle is the same:

You use 50 kJ heating 238 mL of water from 10 C to 60 C, then mix it with 238 mL of 10 C water to get 476 mL of 35 C water.

With a heat pump water heater, the 35C water is cheaper than the 60C water- less electricity for the same amount of energy moved

> Cooling down water you already spent a lot of energy to warm up would be extremely wasteful.

Isn't the energy the same? You use 50 kJ heating 1 L of water from 10 C to 60 C, then mix it with 1 L of 10 C water to get 2 L of 35 C water?

Unless you're using a heat pump water heater.

It's "mass timber" when you use 4x8s and OSB now?

Why do holes need to be prefab in mass timber? Can't you just take a really big spade bit to it?

Weird, in NYC they don't need any excuses to repave the entire street.

Why yes, I would like it, in fact, I might even like to live in one of those "conditions" myself!

I guess 4 or 5 (i.e the occupant load of the house) because this is occupants not evacuated per fire, and the house would not have sprinklers.

I wonder what the fire risk of a detached house is by this model because risk ~ occupant load ^2 would imply houses are very safe.

That looks like the design of a portable AC. It has an exhaust blower.

Are the roadways actually *in* the Michell-Lama development?

Tunnel Approach St & Tunnel Exit St so toxic that citibikers can't get within a block of them?

Will they allow 26-ft fire lanes to be blocked by traffic?

this is almost as good as the Dutch word for "baseball", which I am overjoyed to reveal is "honkbal"
