CIBSE Modelling with DesignBuilder

Summer Overheating: CIBSE TM52, TM59, and Part O

To evaluate overheating risk through dynamic thermal simulation, you can undertake TM52 (non-domestic buildings), TM59 (residential buildings) and Part O (UK Building Regulations) calculations with DesignBuilder and generate TM52/TM59 reports with pass/fail indicators. DesignBuilder streamlines these assessments by providing dedicated output options, templates, and workflows, enabling users to quickly configure models, apply appropriate weather data, and generate compliance reports for both methodologies.

Guidance on generating these reports can be found here: CIBSE TM52; CIBSE TM59, Part-O.

DesignBuilder Overheating Training gives you the skills you need to offer your clients reports demonstrating compliance with the overheating-related requirements of Building Regulations (including Part O), plus the knowledge to comply with relevant aspects of guides and standards such as BB101 and BREEAM using the TM52 and TM59 methodologies.

CIBSE TM54

DesignBuilder allows users to undertake all aspects of CIBSE TM54 modelling with either Simple HVAC or Detailed HVAC options. The process involves creating a robust model that accounts for all regulated and unregulated energy uses, setting realistic operating schedules, and incorporating project-specific data for occupancy, equipment, and controls. DesignBuilder also enables scenario testing and sensitivity analysis, which are key TM54 principles for assessing risks and uncertainties in energy performance. This methodology helps designers identify potential performance gaps early, optimise building systems, and align design intent with actual operational outcomes.

CIBSE TM63

CIBSE TM63 modelling focuses on evaluating a building’s in-use energy performance through calibrated simulation, bridging the gap between design predictions and actual operational outcomes. DesignBuilder enhances TM63 workflows by providing advanced calibration tools, including scripting and optimisation features that allow users to create custom error metrics such as CVRMSE and NMBE, run automated optimisation to minimise these errors, and visualise results using parallel coordinates plots. DesignBuilder supports the import of metered data, iterative tuning of HVAC controls, and even digital twin development for ongoing performance monitoring.
