Question
What three problems does design for sustainability address?
Answer
Waste, pollution and energy consumption — and all three are affected more by how long the product lasts than by what it is made of.
Question
Why is product life the biggest lever?
Answer
Doubling the time a product stays in use halves its material, energy and waste at once, because one product does the work of two. No material substitution comes close.
Question
Why ask where the impact is before choosing a strategy?
Answer
For anything powered the use phase dominates, so insulation and control matter. For anything passive the embodied impact dominates, so mass, processes and life matter.
Question
What turns a sustainability claim into a design decision?
Answer
A measure, a cost and an alternative — for example, "the recycled grade costs 12% more per part and removes the coating, recovered within a year".
