POE in Architectural Design WE HAVE : WE WANT : Structural Stability Water Ingress Thermal Performance From a RISK point of view : Structural Stability
Thermal So we start with Structural Options 1 2 3 monolithic structure... ...leads to... ...detailing problems for water detached structure... ...leads to... ...possible structural solution ...but other less important problems (small, but many)... double structure... ...good water solution... ...leads to... ...but will cost more... oh, and don't forget the ever present : Cost
Buildability So, we end up with two solutions (2, 3) : 2 - Risk is
horrible detailing / possible failure of water barrier
Greater cost
Longer time on site (more cost) 3 - Risk is
Greater cost
Longer time on site (more cost) Note: the main difference Which leads to a validation process with the Client :
"Do you wish cheap, but risky; or expensive but watertight..." Note also - we still haven't come across a really tough cross problem (some slight crosses that I probably haven't even demonstrated here, just removed 'instincitvely')... A simplified, retrospective, solution architecture for a live design problem. NOTE : These 3 criteria are given as the most critical measures of success and perceived to be the most challenging when presented with 'WE HAVE' and 'WE WANT'.
There are many other criteria that are still important and relevant, but these are not presented since, intuitively, they are understodd to be solveable in easier ways (i.e. there are alternatives routes to solution that do not require 'WE HAVE' as a starting condition). And, looking at the 'shape' of it : "I believe the structure is the most important thing to resolve. What are the possible solutions?" Structural Option 1 Structural Option 2 Structural Option 3 Structural Option 1 + Waterproofing Option 1 Structural Option 1 + Waterproofing Option 2 Structural Option 2 + Waterproofing Option 1 Structural Option 3 + Waterproofing Option 1 Structural Option 3 + Waterproofing Option 2 VALIDATION REQUIRED "Then I believe that water ingress is the next priority. What are the possible solutions?" Of course, what is missing ... All of the intuitive decisions left out because they don't work or have additional risk (e.g. miraculous waterproofing systems);
All of the trivial solutions (e.g. sell the monster and buy a proper house);
The (explicit) overriding constraint of money / time (which applies to all processes and decisions);
Possibly 101 other sub-conscious decisions made by an 'experienced' designer(s); ...because we consciously decide that this is most important 'risk' criteria... NO! NO! NO!
