By the end of this course, participants will be able to analyse how slope and overshadowing affect NatHERS modelling outcomes and 7-star compliance pathways on residential projects. They will understand how to capture and interpret accurate site data using methods such as drone surveys and 3D laser scanning to support thermal modelling. Participants will be able to apply cost-benefit strategies that combine glazing, insulation, and window configuration adjustments to improve compliance outcomes on constrained sites. They will also learn how to collaborate effectively with NatHERS assessors through structured documentation and iterative modelling workflows. Finally, participants will be able to develop defensible compliance records that reduce risk during documentation, certification, and construction stages.

Learning Outcomes

  • Analyse how slope and overshadowing influence NatHERS modelling inputs and residential 7-star compliance outcomes.
  • Apply cost-benefit strategies to balance glazing performance, insulation upgrades, and window sizing on constrained sites.
  • Evaluate the suitability of drone surveys and 3D laser scanning for capturing accurate site and obstruction data.
  • Develop structured workflows for collaborating with NatHERS assessors during iterative modelling and documentation stages.
  • Identify how climate zone conditions alter the compliance impact of solar access limitations and site geometry.
  • Create defensible compliance documentation and change management records that support certification and construction compliance.

This ensures that CPD efforts align with professional regulatory requirements.

PC19, PC28, PC31, PC33, PC47

PC19 (site analysis and feasibility): The course focuses heavily on analysing difficult site conditions such as slope and overshadowing, including early-stage data capture and feasibility implications for NatHERS compliance.
PC28 (building sciences): Detailed exploration of thermal geometry, heat movement, glazing performance, and insulation strategies directly aligns with applying building science knowledge to optimise design performance.
PC31 (environmental sustainability): The course centres on achieving 7-star NatHERS ratings, integrating energy performance, solar access, and environmental modelling as key sustainability outcomes.
PC33 (environmental systems integration): It evaluates and combines systems such as glazing, insulation, and solar access modelling, demonstrating coordinated environmental system design responses.
PC47 (documentation and accuracy): The emphasis on documentation strategies, assessor collaboration, and producing accurate NatHERS-ready inputs aligns with the requirement for precise and coordinated project documentation.

What’s Included

This course examines the thermal and compliance challenges created by sloping and overshadowed residential sites under the NCC 7-star framework. It explores how difficult site conditions affect passive solar performance, heat loss, glazing effectiveness, and NatHERS modelling accuracy across different climate zones. The course also examines the role of accurate site data collection, including drone surveys and LiDAR scanning, in improving compliance outcomes and reducing redesign risk. Participants will gain insight into integrated specification strategies that balance design intent, construction cost, and thermal performance. In addition, the course examines documentation workflows, assessor collaboration, and compliance management practices that support reliable and defensible project delivery.

  • A 1-hour video session covering NCC-aligned strategies and real-world case studies.
  • An interactive quiz to test and reinforce knowledge.
  • An audio summary version via NotebookLM for flexible, on-the-go learning.
  • A downloadable certificate of completion for CPD compliance reporting.
  • Centralised CPD tracking dashboard to support audits and personal recordkeeping.
