MATERIALS AND COMFORT
A material is not sustainable in the abstract. It must be compatible with the building, available, buildable, durable, and able to contribute to comfort in the real context.
HEALTH AND COMPATIBILITY
Emissions, air quality, moisture, hygrothermal behavior, and compatibility with existing assemblies are considered together. Decisions require technical data sheets and relevant checks.
PERFORMANCE AND SERVICE LIFE
Summer and winter performance, daylight, acoustics where relevant, strength, repairability, maintenance and end of life are compared against intended use.
ORIGIN AND SUPPLY CHAIN
Origin, availability, lead time, processing, contractor expertise and replaceability shape feasibility as much as theoretical qualities.
DOCUMENTED COMPARISON
Alternatives are assessed against explicit criteria. A natural material is not automatically the best choice, and an industrial product is not automatically excluded. Context and performance guide the decision.
QUALITY OF LIFE
MEASURABLE COMFORT, BUILDABLE DETAILS
