News Release: Major Update Cuts AirEx Floorvent SAP/RdSAP Modelling from 15 Minutes to 60 Seconds

London, 6th June 2025: AirEx has announced a dramatically improved integration of its smart Floorvent product into SAP/RdSAP assessments via the official BRE Appendix Q API tool. While it has been possible to model AirEx Floorvent since 2022, the latest update eliminates the complexity and manual effort that previously made the process cumbersome and time-consuming for retrofit professionals.

The energy-saving impact of AirEx Floorvent can now be quickly and accurately modelled using standard EPC/EPR XML exports from platforms such as Elmhurst Energy. This development removes the need for complex manual adjustments, enabling the product to be included at scale across retrofit programmes; saving time and improving EPC outcomes.

The key benefits of the tool include: 

• Eliminates modelling complications
  AirEx Floorvent can now be modelled using a standard XML export and online API tool. This streamlined method avoids time-consuming manual steps, making it significantly easier to include the product in large-scale assessments.
  

• Fast and reliable process
  Using the official BRE Appendix Q API tool, Retrofit Coordinators can generate verified energy-saving data for the recognised energy efficiency measure and enter the figures into EPC software in minutes, ensuring compliance and consistency.
  

• Supports accurate EPC and EPR uplift
  Correctly modelling AirEx reduces uncertainty in the process and enables measurable improvements to energy ratings, supporting better outcomes for compliance, funding eligibility and long-term housing performance.

Jim Cottom, Retrofit Designer & Retrofit Coordinator at PH Jones, commented, “The older methodology for modelling AirEx was quite time-consuming and could be a barrier when working at scale. Previously it’s taken me 10-15 minutes to model AirEx, this new process takes under 60 seconds. It’s far simpler and removes the complexity that previously slowed things down,”

Agnes Czako, CEO at AirEx followed, “We’re really pleased to launch this improved tool, which has been developed in response to feedback from the field. Our hope is that it will simplify the modelling process and make it even easier to include AirEx installations in retrofit strategies,”
