OFFICIAL11 What is mentioned in the lecture as an application of the principle that "form follows function"?

[00:00.00]NARRATOR: Listen to part of a lecture in an architecture class.
[00:06.22]MALE PROFESSOR: Today we're taking, uh, a little detour from the grand styles of public architecture we've been studying... to, uh, look at residential architecture in the United States. [00:21.68]Since this is something we can all identify with, I, I think it’ll help us see the relationship between the function of a structure and its uh, its style, or form;
[00:35.00]this has been an ongoing theme in our discussions, and we'll be getting back to it in just a moment. [00:41.09]Uh, but before we get started, I want you to take a moment to think: Does anyone know what the single most popular style for a house in the United States is today? Bob? 
[00:54.99]MALE STUDENT: I bet it's the ranch-style house.
[00:57.72]MALE PROFESSOR: Well, in this area, probably—[01:00.79]But are we typical? Yeah. Sue?
[01:04.84]FEMALE STUDENT: How about the kind of house my grandparents live in? [01:08.02]They call it, uh, a Cape Cod... 
[01:11.31]MALE PROFESSOR: That’s the one. [01:12.62]Here's a drawing of a, of what we consider—of a classic Cape Cod house. [01:18.89]These days, you see this style all over the United States, [01:27.51]…uh, but it first showed up in the U.S. northeast—in the New England region—around the late 1600s. [01:35.40]Uh, For those of you who don't know the northeast coastal region—um, Cape Cod is a peninsula, a, a narrow strip of land that juts out into the Atlantic. And um…so, so many houses in this particular style were built on Cape Cod, that the name of the place became the name of the style.
[01:58.39]uh, now, why did the Cape Cod-style house become so popular in the northeast? [02:05.38]Well, one reason is that it’s a great example of form following function. [02:12.34]Uh, we've, we've talked about this design principle a lot…about form following function…and…[02:19.10]what’d we say it meant? [02:21.40]Someone give me an application of this principle. [02:24.59]What does this concept, that form should follow function, [02:28.66]how would it be applied to housing design?
[02:33.45]FEMALE STUDENT: Well…if it means that the design of a building should be based on the needs of the people who use it. Then…well…the architect has to be very practical—to think about... the people who'll actually be living in the house…or working in the office building—whatever…[02:55.41]So, for the architect, it's all about the users—not about showing off how creative you can be.
[03:02.31]MALE PROFESSOR: Good! [03:04.71]Of course, for a Cape Cod house, it might be even more accurate to say that, uh, form also follows climate. [03:13.98]Who knows what the climate’s like on Cape Cod?
[03:20.96]MALE STUDENT: Cold in the winter!
[03:23.05]FEMALE STUDENT: And whenever I visit my grandparents, it's really wet— [03:27.23]it's usually either raining or snowing or foggy…and windy, too… [03:33.24]I guess because it's so exposed to the ocean? 
[03:36.63]MALE PROFESSOR: That's right. [03:37.57]So take another look at this drawing, and, uh, you can imagine how this design might be particularly helpful in that kind of climate. [03:47.95]Notice how the house sits fairly low to the ground. [03:55.76]Uh, this relatively low, compact structure helps the house withstand the strong winds blowing off the ocean.
[04:03.70]An-and look at the slope of the roof. The steep angle helps keep off all that rain and snow that accumulates in the winter. [04:11.90]A-another thing: Cape Cod houses usually face south, to take advantage of, of the sun's warmth through the windows—[04:20.57]that’s helpful in winter. [04:22.78]Now. What can you tell me about the chimney? A-about its location.
[04:28.07]FEMALE STUDENT: Well. It's in the middle…[04:30.42]Because…Does that have something to do with heating the houses…[04:34.81]I mean, since—the heat never has to travel very far.
[04:38.36]MALE STUDENT: That'd mean you can heat the house more efficiently, right? 
[04:41.50]MALE PROFESSOR: Exactly. Now, see how the house has very little exterior decoration? Tha-That's also typical of early Cape Cod houses. [04:51.37]The wind was one reason—nothing sticking out that might blow away in the harsh weather.  Uh, but there was probably another reason—not related to the climate—um, more, um—more a reflection of rural New England society back then. [05:08.61]You see, Cape Cod houses were not built in the big cities, where all the rich people lived back then. [05:16.24]These were modest dwellings.
[05:18.90]The people who built them simply couldn't afford lots of expensive decorative details. [05:25.02]But, it was more than just a matter of money. [05:29.09]In these rural areas, people depended on each other for survival: [05:34.19]uh, neighbors had to help and support each other in a difficult environment. So, you didn’t want to appear to be showing off.
[05:43.95]You'd want to avoid anything that might set you apart from your neighbors—the same people you might need to help you some day. [05:52.73]So, so, all this helped to create an attitude of conformity in the community…and you can see why a modest—a, a very plain style would have become so widely imitated throughout rural New England.
[06:09.25]FEMALE STUDENT: It is plain but, you know, it's nice looking.
[06:16.24]MALE PROFESSOR: Good point! And, in fact, it's precisely that aesthetic appeal—the um, uh, the purity…the nearly perfect proportions of the house—that's another reason for the Cape Cod's enduring popularity—even in places where the climate's so mild that its functional design doesn’t matter.
