The Financial and Legal Reality of Energy Sieve (Passoires Thermiques) Regulations In the contemporary French property market, building performance assessments have shifted from informational courtesies to binding legal and financial drivers of value.

The widespread introduction of Portland cement-based mortars and synthetic polymer coatings during late 20th-century renovations represents a catastrophic disruption to the historic built environment. Pre-1948 solid masonry walls are dynamic, vapor-permeable systems designed to absorb and evaporate moisture across their entire surface area—a mechanism colloquially known as “breathing.” The application of a modern, rigid Portland [...]

Sub-soil moisture transit within pre-1948 building envelopes is primarily governed by capillary rise (remontées capillaires), a thermodynamic process driven by the surface tension of water interacting with the micro-porous structure of historic building materials. In the absence of a modern impermeable damp-proof course (DPC), moisture from the underlying water table is drawn vertically into the [...]
