When retrofitting existing buildings to improve their energy efficiency, it is vital to consider the impact on condensation risk. Adding insulation can change the temperature distribution across the building envelope, sometimes leading to colder internal surfaces in unexpected places. This can create new or worsened problems with condensation and mould.
Regulatory bodies like Trustmark are increasingly focused on ensuring that retrofit projects are supported by robust evidence demonstrating that condensation risks have been properly assessed. By using AutoPSI to calculate fRsi values, you can identify potential risks before work begins, model different insulation strategies to find a solution that minimizes both heat loss and condensation risk, and provide clear evidence that your retrofit design meets the required standards for health and safety.
This makes fRsi analysis an indispensable part of any high-quality retrofit project.
