High CO₂ doesn’t just make a room stuffy.
It quietly makes you slow. It’s the subtle cognitive tax that dulls your film, flattens your conversation, and steals the clarity you worked all day for.
Your house—be it your living room, lounge, or sitting room—is meant to restore you; why is the air making you underperform?
More than comfort, this continuous ventilation deficit is the root cause of the moisture build-up that leads to condensation and hidden mould. Our continuous-flow units actively purge this cognitive and moisture drag, protecting your health and your property’s integrity.
We replace passive loss with active comfort.

Part F: Why the Standard Matters in Your Living Room
The Building Regulations Approved Document F (Volume 1: Dwellings) doesn’t just ask for ‘adequate means of ventilation’—it is the legal minimum required to stop your home from becoming an uncomfortable, mould-ridden vessel that steals your health.
For habitable rooms like your living room, lounge, or sitting room, Part F’s requirement is subtle, yet unforgiving.
The Standard: Volume, Not Just Location
The official standards for continuous mechanical ventilation (Systems 3 or 4, which VENTI provides) typically mandate a Whole-Dwelling Ventilation Rate based on the number of bedrooms.
However, the size of your living room is the real sticking point. Why?
-
The Law of Volume: The continuous airflow must be sufficient to deal with the unique demands of that large space. Your living room (unlike a bedroom) is the most occupied, socially active, and thermally variable room in the house.
-
The Silent Conflict: This is where the friction lies. The requirement for adequate continuous flow is often in direct conflict with the client’s absolute demand for silence. A system that just scrapes the compliance line is often running too hard, leading to noise complaints, callbacks, and compromised comfort.
-
The Trickle Vent Folly: If you rely on the ‘less airtight’ strategy of trickle vents and intermittent fans (System 1), Part F demands a minimum Equivalent Area (EA) of up to 8,000 mm² in each habitable room. That’s a large, passive, draught-ridden hole—the very antithesis of thermal integrity and comfort.
The VENTI Response: Compliance by Guarantee
The VENTI approach is to satisfy Part F by removing the conflict between compliance and comfort.
We treat your living room’s ventilation not as a whole-house average, but as a guaranteed, quiet outcome for that specific volume.
