Modelling Thermal Bridges in Heat3
As building codes across North America gradually tighten requirements on the building envelope performance, the importance of mitigating thermal bridging is increasing. For instance, in the soon to be released update to the National Energy Code for Buildings (NECB), the thermal bridge effect of structural penetrations, shelf angles, anchors, and ties, among other elements, can no longer be ignored.
Heat3 is a 3D thermal modelling tool that lets users calculate the impact of 3D thermal bridges. The tool is gradually becoming the standard tool used for calculating thermal will thus be an invaluable tool for building energy modellers and envelope consultants to understand.
In this two-day course, participants will learn the fundamentals of thermal bridging calculations. Common 2D and 3D details and their modelling conventions will be examined. Modelling techniques will be taught using Heat3. Participants will be given the opportunity to perform calculations and have them reviewed in class.
- Gain better understanding of heat loss in buildings due to thermal bridging
- Understand what comprises a high quality junction detail
- Assess degree of thermal bridging in a junction qualitatively
- Learn basic commands in the steady state numerical analysis software Heat3
- Create 2D and 3D thermal models of junction details
- Set up the steady state models to output correct results
- Calculate heat flows in Heat3
- Analyse the calculation results to ensure accuracy
- Learn and apply correct thermal bridging modelling conventions
- Quantify the degree of thermal bridging at junctions
- Gain practical experience in the calculation of thermal bridging heat loss
- Account for thermal bridging in building energy modelling software
Intended Audience: Building energy modellers, building envelope consultants, engineers, architects and other building professionals that wish to understand and quantify thermal bridging.
Prerequisites: Participants must have a familiarity with Excel and basic building heat loss calculations.
Optional Course Extension: Course participants wishing to further refine their modelling skills will have the opportunity to submit models they complete after the course. Feedback will be provided on these models at an additional charge per model.
Course Requirements: Laptop with Heat3 v8.0 (full version or demo) preloaded; MS Excel (or equivalent); calculator, pencil and notepad for sketching. A 30 day trial version of the software can be downloaded here.
