Of course, creativity can still occur through tentative, incremental, accountancy-oriented activities – but it is not likely. It is even less likely that underlying norms and assumptions will be challenged in the process. Designers should be encouraged to think about maximizing positives and to imagine new ‘possibilities’ – not ‘impossibilities’ like predicting collateral damage in a complex system. ere is no harm in advancing our ability to estimate the number of beans in a jar.4 However, it not the kind of interactive, outcomes-oriented, collaborative design processes that stimulate synergies and syntheses. Measuring the predicted impacts of a proposed development relative to standard ones keeps the nish line close to the starting block. It does not mean we go any faster. e question should be ‘How can we achieve a genuinely sustainable building?’ – not how to measure how much less bad it may be. Eco-logical design tools should instead help designers ‘think outside the box’ to create reversible land-use planning and net positive, adaptable designs, materials, forms and other win-win-win solutions.
