Vulcan's take on FHS and HEM consultation responses
The Future Homes Standard and Home Energy Model consultation responses make clear why firms should prepare for HEM now, not later.
Faster beats familiar
HEM will reward faster workflows, not familiar ones. Geometry-first model creation is a better way to handle HEM's extra detail than recreating SAP-era forms.
Introducing H3: an open-source way to create home energy assessments aligned with real-world measurements
H3 is a wrapper around the Home Energy Model, used to compare predicted heat-loss from the Home Energy Model with real-world measurements, calibrate HEM models, and review results in an interactive HTML report.
Introducing the Vulcan API: bringing HEM to the home energy modelling software of your choice
Third-party software can now integrate Vulcan's HEM regulatory workflows without rebuilding the required qualification & quality assurance layer.
The Home Energy Model era needs a new Energy Assessor Scheme
Vulcan is becoming an OCDEA accreditation scheme to raise the bar on energy assessment quality and value in the Home Energy Model era.
