Last month the Washington Post published a nice article that detailed the deep water cooling system that the city of Toronto, Canada uses to keep itself cool. For the unfamiliar, deep water cooling at its simplest means sucking up very cold water from the bottom of a lake or ocean or wherever you can get very cold water, and then pumping that inland to absorb heat before cycling it back.
Of course, for the longer explanation—and what makes Toronto’s system different—you should read the article. And for our purposes it includes some nice illustrations that diagram just how that system works. The screenshot below captures the basic process I just described, but there are additional illustrations that do a great job showing just how the system works.
What I particularly enjoy about this style is how the illustrations of the building and similar are minimal and restrained. This allows the diagrammatic elements to come to the forefront, which is important to make the system understood.
