Instructor Mike Newman will discuss issues related to the generation or evaluation of design alternatives that synthesize environmental, cultural, behavioral, technical and economic issues.
When you are done with this course, you will have a thorough understanding of the content covered in the ARE 5.0 Project Planning and Design Exam including design concepts, sustainability/environmental design, universal design, and other forms of governing codes and regulations.
So let's think of an example here where we have an issue that is coming from the kind of program and kind of the options that we went through uh, and, we're trying to think about the impact that that issue is going to have on our final plan making. So, let's say we decided uh, that we're doing a multiple family apartment building, and we want to build it with passive principles. What would be the issues from that decision that would impact our planning process? Well, the obvious ones are gonna be fenestration and orientation.
Uh, we can't really think about passive principles without thinking about where the sun angles are, how the light's gonna get into the building, solar gain, are we trying to get accepted, are we trying to block it? Is it a temperate situation where we're trying to do both depending on the season? And sort of, what's the sort of general idea? And if it's about sunlight, and about passive gain of heat, well then it's all gonna be about the angle of the sun and the relationship of the building to the angle of the sun.
So, how it sits on a sight uh, how that sight is related to the path of the sun; but also the section of the building, and how uh how the sunlight will uh hit the building and either bounce deeper into the space, or get blocked from going in directly, and create either an indirect light, or a direct light. All of that.
So, if we want to say, for example, uh, just have a heat sync, so here's our space here. And we really want to get the sunlight to be able to come in and just give us a very beautiful, warm feeling in the floor, and actually help spread the heat, and ya know, maybe a sunny place where it gets cold.
Uhm, well okay, that means that decision is saying that this floor material, at least to the point where the sun's going to reach it needs to be a material that can accept the heat, that has the ability to be a heat sync. So maybe this is concrete, or maybe it's slate, or tile or something like that. So that decision to go with this particular passive idea is trying to create a situation where I have to have that material there in order for that radiant quality to come back up from that sunlight warming that particular space.
So, that decision to go with a passive principal is saying not only do we need to have the fenestration, these windows aligned with the solar path to be able to let the sunlight come in, but we're now talking about what's our floor structure made out of?
What's our floor finish made out of? Uh, that it starts impacting all these other decisions. If we decided that we wanted to do this passive heating with this system but have a wood floor, well, it won't really work. It'll work to a degree The wood floor will warm up as well, but it won't warm up any near the level of something that has more of the ability to be a heat sync. So, uh that's one example of a design decision that starts being uh impacted by the passive system.
Now, it might be that our passive system is not about solar gain or light at all. Maybe it's about convective currents. Maybe it's about creating air movements through a space. for an apartment building. So we can imagine a plan of an apartment building. There's a stair at one end.
There's a stair at the other end. And there's a corridor that stretches in-between. And then they've got a bunch of units. So, I've got a whole bunch of units on a corridor. It's double loaded corridor. So, okay, get that. That makes sense. But not if it's about convective currents. Cuz, if this is about convective currents, that means that window there and that window there we have to somehow encourage the air to come in, and then blow back out.
It'll be very difficult to make that happen. So if we say that this is about passive principles and those passive principles are about convective currents what that's telling us is this apartment building wants to look more like I'm just gonna make it up here, (long pause) Cuz now what we have going is I can have windows there and there and there and that's going to start to allow air to flow in and out differently than it would've in a flat wall.
I can have windows on two different sides, and air will flow right across, through there. And it'll pull some of the inner air with it. So, if it's about convective currents, I need to think about where those openings are going to be.
Uh, is it about finding shafts that will move through the space so that air can come from the windows back in, and then get to that shaft and go up to the roof? Right, I have to build in those elements in order to make that work. Once we said it was about convective currents, the plan of the building changed. Now, it might change so much that we actually say we're not going to do it as a double loaded corridor.
Maybe we just want to do a simple building, and put a little corridor on the end. We're gonna have this be a stair there a stair there. And this is maybe outside. So I come up the stairs and I'm in an outdoor corridor. And these folks have a window there and a window there. And the next ones have a window there and a window there. And that clearly is gonna make the ability to have air move right through that space.
So, the fact that we said we're gonna follow the principles of passive design and we happen to be talking about, in this case, convective currents, it's dramatically changing our floor plan. We're gonna move away from this example, and we're gonna start finding these other possibilities.
Because if we wanna do that, we need to find a way to make it work, and that's gonna be through the planning process. It's not something that we just add on later. You can't add it on later. It has to be done through the planning process. You can't just put a building and then say later, Well, okay, we want the sun to hit these windows if there not oriented towards where the sun is. You can't just assume the air will find it's way down a corridor and around the corner. You have to create really plausible convective currents.
So, this is, uh that idea that we're talking about all those options before then we choose some of those options, and now the choice of those options is impacting our finalization of those floor plans, and sections, and elevations, and ceiling finishes, and floor finishes, and all those things; that they're all intertwined together.
