Participation in the national CORE and Scale trials provided practical insight into existing-home assessment, field delivery, documentation requirements and the operation of emerging rating pathways.

Property-Sector Collaboration

Cotality Collaboration

A non-exclusive collaboration supporting the application of home-energy assessment within broader property information and residential rating environments.

Spatial Methodology

Urbanfinity Integration

Urbanfinity spatial methodologies extend Certified Energy’s work into viewshed analysis, visual impact assessment and site-based interpretation of development within its wider context.

 

Technical Platforms

Recognised tools and structured systems supporting consistent analysis and review.

Certified Energy works across established rating software, simulation environments, spatial methodologies and internal workflows. Together, these systems help organise information, test performance and maintain clarity across different building types and regulatory contexts.
