    Be very careful when the word resilience is used. The term is used to mean so many difference things by different people that it lacks meaning.

    While social equity and biodiversity are worth consideration they are not necessarily best implemented in the context of building codes.

    Building codes will need to change in response to climate change. Still the idea that designs should be based on predictive data instead of the criteria in the building code should not be the basis for building permit approval
