Air Permeability Testing for Historic Building Renovations
Renovating historic buildings can be challenging, particularly when dealing with air permeability, which affects energy efficiency and indoor air quality. Air permeability testing is crucial for identifying problem areas that need targeted interventions, ensuring improved energy efficiency without compromising the building’s historical and structural integrity. Common challenges include inconsistent building materials, age-related degradation, and structural inconsistencies, all of which require specialised techniques. At Ratio Seven, our comprehensive approach involves initial assessment, advanced diagnostic tools, targeted intervention, and post-intervention testing, guaranteeing that all work respects the building’s historical significance while making it more energy-efficient and comfortable.
