ABSTRACT
End users enjoy the benefits of the built object, which allows them to carry out their various activities. By considering buildings as machines that interact with users, ecodesign endows users with a significant responsibility of which they are not always aware. The ambit of ecodesign is restricted to consumption and major upkeep, since these are the main generators of flows during the operation phase along with the production of waste. Ecodesign allows a certain capacity for steering, or more precisely evaluating, user behaviour and being in a position to enter into more constructive dialogue. In ecodesign, a virtuous cycle is likely to occur, unless it is overshadowed by the more powerful phenomenon of land income. Ecodesign, in setting out performance levels, introduces a need for instrumentation that can be broken down into: a capacity for acquiring data for monitoring and, as a result, a capacity for managing equipment.
