7617: "Well this is something that sort of marked my entire career, long before I became an architect, but this interest in controlling thermal boundary layer phenomena and the development of the thermal boundary layer, and not the boundary layer that we see in flight that deals with velocity and pressures, but really the boundary layer that comes about due to density changes. So the boundary layer that emerges when I have a small temperature difference, so basically natural convection, so this is something that’s interested me my entire life. My work as an architect was very much in beginning to understand that everything in a building is a thermal behavior. So once we get rid of the systems, once we get rid of anything that’s extent and start from scratch, every single thermal behavior in a building is one of these natural convection behaviors, whether it’s the boundary layer around my body, whether it’s heat rising from a piece of equipment or a lamp or computer, whether it’s a wall surface with things going up or down, depending on the temperature, every one of these things is natural convection and every one has this really thin very tight boundary layer. And our systems try to, in essence get rid of that boundary layer because it treats everything as a big mixed volume. So this big mixed volume is intended to not allow anything to operate individually and my questions are very much what if we got rid of the large integrated mixing system that’s trying to dilute all those energies, and allow each of these energies, comes back to what’s local, but allow each of these energies to maintain their autonomous boundary layers. And if you do that, you can work on them at the boundary layer level. We think about something like glazing and what we know about glazing, we’ve dealt with glazing certainly for the last hundred years, is that there was enormous conduction loss, or whichever direction we might be going, but there’s a very high rate of conduction through that. And that’s what has led us to double glazing, triple glazing, inner gas filled. It’s what led so many people in this day and age to jump on the Aerogel bandwagon, this idea that it’s a translucent material that’s super-insulating. So the desire always has been to make this super-insulating. On the other hand, if you understand how it’s boundary layer functions, you can put in a tiny little heat sink or tiny little heat source in that boundary layer and have a thin piece of glass behave as if it’s a thick wall. And so this is basically the one thing I would love to be able to work out. it’s something that I can model and beginning not to understand just where do I deploy that, where do I make those interventions in an existing environment which is always going to be specific to it’s circumstances. How do you begin to say I can put a little heat sink here, I can put a little resistance wire here and I can completely control what’s going on in any given surface no matter what the material is. No matter what the circumstances are."
