Opens the building to cool night air, pre-cooling thermal mass for the next day (relies on passive/natural ventilation).
Note: Cost, carbon and footprint are rated against the other options for this same need, not in absolute terms.
A climate with a real day/night temperature swing and openings that can be safely left open overnight
No sizing or quantities: how much a technique yields, and how much a household needs, both depend on the build and the people, so the catalogue compares options rather than dimensioning them. It carries no bill of materials and no build sequence, and it is written for an oceanic, clay-soil climate (Normandy, France). Regulatory notes are indicative and need confirming locally.
