NCC 2022: J1V3

This 49-min course provides a comprehensive guide to conducting J1V3 simulations within the Better Buildings platform. Designed for professionals, it covers the intricacies of NCC J1V3 compliance, from understanding reference building automation to interpreting detailed simulation results for performance validation.

Course Structure

This course introduces you to the NCC 2022 J1V3 verification method, showcasing how the platform automates the complex process of modelling reference buildings based on your proposed design whilst applying deemed-to-satisfy provisions. You'll learn to initiate J1V3 assessments for relevant building classes and understand how this automated approach streamlines what would otherwise be a highly technical and time-consuming compliance process.

You'll explore the two primary compliance criteria that form the foundation of J1V3 assessment: greenhouse gas emissions and thermal comfort performance. The course teaches you the quantitative comparison rules for GHG emissions against reference buildings, specific Predicted Mean Vote (PMV) thresholds for thermal comfort including spatial and temporal compliance requirements, and how to leverage on-site renewable energy to reduce proposed building emissions. You'll also dive into critical reference building assumptions covering default infiltration rates, air conditioning control set points, lighting power densities, and advanced options like combining window fractions and simulating actual shading multipliers that distinguish this approach from standard deemed-to-satisfy methods.

The hands-on component guides you through running and managing simulations, understanding factors that affect simulation time like solar distribution settings, and interpreting results through detailed Building Emissions and Thermal Comfort reports that show energy flow breakdowns and PMV rankings for individual zones. You'll master the critical Geometry Summary and Thermal Envelope visualisation tools for verifying model inputs and identifying potential geometric anomalies before accepting results. The course concludes with comprehensive guidance on generating J1V3 reports as performance solutions, adding essential metadata for certifier clarity, and using comparative analysis tools to toggle between proposed and reference designs for thorough documentation.
