David!<br>
I have heard many speakers reference Brands work, but it is true that it
is not mentioned much in the limited building literature.<br>
I attach an scan from Brand's book from those who dont have it.
David's really a good update.<br><br>

It's more conceptual than what I think you're looking for, but here's a
link to the illustration we created for my book, based on a combination
of Benson, Stewart Brand and Philip Proefrock's writing on the idea.

<font color="#231F20">Durability or Planned Obsolescence?<br><br>
</font><font size=2 color="#231F20">In light of the amount of material
and embodied energy<br>
invested in every building, a clear element of sustainability<br>
is ensuring that it has a long life. With few exceptions<br>
(such as temporary structures), building for durability is<br>
one of the basic tenets of ecodesign. But creating a structure<br>
that will endure over the years is not just a matter<br>
of designing it with long-lasting materials. One perhaps<br>
obvious point: the building must be valued by those who<br>
use it. If the design does not result in a building that functions<br>
well and is pleasing, then it is likely to be renovated<br>
or demolished sooner.<br><br>
If a building is to last, then it needs to be able to adapt<br>
to changes in usage, technology, and cultural patterns. In<br>
other words, it needs to be durable and flexible. “Design for<br>
deconstruction” is one way to achieve flexibility and provide<br>
for the eventual need to replace the building. The industrial<br>
design world has for a while been at work on design for<br>
disassembly (DfD, which can also stand for design for
deconstruction).<br>
One high-profile example involves the office chair;<br>
several manufacturers have engaged in a kind of competition<br>
to design the chair that can be disassembled the fastest<br>
and with the fewest tools. The objective is to make recycling<br>
more economically viable by designing so that materials are<br>
readily separable at the end of the product’s life.<br><br>
Buildings, of course, are more complicated than<br>
office chairs. And they should last longeror at least parts<br>
of them should. Stewart Brand, in <i>How Buildings Learn</i>,<br>
describes how buildings should be thought of as having<br>
six layers, ranging from the site, which is timeless, to the<br>
skin and structure, which may last generations, to furnishings<br>
that are frequently
changed.</font><font size=1 color="#231F20">6<br><br>
</font><font size=2 color="#231F20">The application of this concept has
become known as<br>
open building, and it can lead to a fundamentally different<br>
way of understanding buildings in which these layers are<br>
independent.</font><font size=1 color="#231F20">7
</font><font size=2 color="#231F20">To a degree, modern offices do this
already<br>
with non–load bearing, demountable partitions and<br>
mechanical cores. But more often than not, an office renovation<br>
or a home remodel involves brute force removal<br>
(destruction, really) of building materials. Imagine if the<br>
walls of our homes were built so that wiring and plumbing<br>
could be easily accessed for repairs and modifications<br>
without cutting holes in walls, perhaps without encountering<br>
obstacles, and then without patching and painting<br>
(or, for instance, if windows could be replaced without<br>
entailing interior and exterior damage). The key lies in<br>
separating the layers so that the less durable layers can be<br>
altered without interfering with the others.<br><br>
Open building also relates to the concept of futureproofing:<br>
designing and constructing buildings to anticipate<br>
the future. If, for instance, PV panels are not in the<br>
budget but may be added eventually, run conduits to the<br>
roof and provide support structure so that the panels and<br>
wiring can be accommodated later with minimal disruption<br>
and cost. Similarly, a gray-water system may not be<br>
allowed by current code, but if you provide the necessary<br>
plumbing at the outset, it can be implemented by simply<br>
opening a valve when the code catches up.<br><br>
