Ventilation Assessment

Ventilation Assessments for Heritage Buildings in Cornwall

At Truscott Building Preservation, we provide expert ventilation assessments for Cornwall’s heritage buildings, ensuring that your property’s unique needs are met while maintaining its integrity. Proper ventilation is crucial in managing moisture levels and preventing issues such as damp, mould, and condensation. Our assessments align with Part F of the Building Regulations, which sets minimum standards for ventilation rates to ensure adequate airflow and the prevention of excess moisture build-up in buildings.

In heritage properties, ventilation must be carefully considered to avoid introducing issues that could compromise the building’s materials. We assess the minimum air supply rates (LS rates) as outlined in Part F, ensuring that the airflow meets the requirements for both comfort and moisture control without over-ventilating, which can lead to energy inefficiency.

One common concern we address is the over-reliance on Positive Input Ventilation (PIV) systems. While PIV systems are sometimes installed to increase airflow, they can mask underlying issues such as inadequate ventilation in the building fabric. Excess air pressure can reduce the evaporation of moisture from walls, which, in turn, exacerbates damp problems by forcing moisture deeper into the structure.

Our comprehensive ventilation assessments help identify the most effective, sympathetic solutions to improving air quality and moisture control. This ensures that your heritage building remains healthy, dry, and protected, while respecting its historical character.
