Flixo Energy Training Masterclass

Practical Thermal Bridging Analysis for Building Professionals

Delivered by BRS, 12 hours of Expert-Led, Hands-On Learning

Why Take This Masterclass?

Thermal bridging is among the most misunderstood and underestimated factors affecting energy efficiency, condensation risk, and building comfort. This masterclass gives you the tools, knowledge, and confidence to model, simulate, and report thermal bridging scenarios using Flixo Energy*, one of the market’s most powerful and user friendly tools.

Designed and delivered by industry experts at Building Research Solutions (BRS)**, this comprehensive two day masterclass blends software training, building physics, and regulatory application into a single learning experience.

Whether you are working towards Passivhaus certification, improving SAP and SBEM inputs and outputs, optimising thermal envelope design, or just wanting to understand how heat and relative humidity move through real buildings, this masterclass is for you.

Importantly, this masterclass is designed to meet the British Standards, European Standard, and International Standard for computational calculation of linear thermal bridging – BS EN ISO 10211. The information used to build the masterclass, and the learning outcomes that you will achieve have been calibrated to align with the UK conventions for the numerical calculation of linear thermal bridging and temperature factors – referred to as the BR 497 and the supporting guidance in BRE IP1/06.***

*The training masterclass is explicitly specific to the use of Flixo Energy. Flixo Frame and the frame elements of Flixo Pro are NOT covered in this masterclass.

**BRS are now the Environmental and Sustainability Expertise Area of Okana Global

***The training masterclass may refer to Passivhaus. This is not a Passivhaus accreditation course. As such, all the examples and conventions covered in the course are specific to UK National Calculation Methods for SAP and SBEM, and align with Part L (Eng, Wal) Section 6 (Scot), Part F (NI). However, the modelling and simulation methods defined match those of Passivhaus, but the calculation method is different.

What You’ll Learn

The masterclass is divided into two focused learning components:

  • Component 1: Using the Software – Practical Training with Flixo Energy Software
  • Component 2: Application of the Science – Applied Science of Thermal and Hygrothermal Bridging

 

You’ll leave the masterclass with real skills not just theoretical understanding.

Component 2: The Science & Application of Thermal Bridging

From Building Physics to Regulation Ready Outputs

On Day 2, we zoom out from the software and explore the why behind the how. You’ll learn the key building science concepts, metrics, and regulations that underpin thermal and hygrothermal analysis.

Module Breakdown:

The Science of Thermal Bridging

  • Understand every possible appropriate boundary conditions for a wide range of junction types
  • Create Psi-values for complex building elements like basements, ground floors (suspended and ground bearing), and internal separating walls.

Key Metrics & Conventions for Hygrothermal Analysis

  • Understand the spaces and cavity layers, and the how the different types of air movement (unventilated, minimal ventilated, slightly ventilated, and well/fully ventilated) are defined and how to handle these in your model
  • Model and evaluate 2D surface condensation, 2D interstitial condensation, and dew point risks
  • Go beyond temperature – learn how relative humidity behaves through junctions
