Why site evidence still matters before heat loss software

Heat loss and design software can only calculate from the information it is given. Vertex is built to make sure that information is captured properly on site first.

Software is downstream of survey day

Heat loss software, design platforms, emitter sizing tools, and sound-assessment workflows all depend on one thing first: the quality of the information captured on site.

What software does well

Design and calculation tools are valuable. They help teams turn inputs into heat loss outputs, sizing decisions, and technical design work.

What they cannot fix

If measurements are incomplete, the loft evidence is weak, the cylinder options are unclear, or the electrical detail was never captured properly, the software is still working from a weak site record.

The site evidence installer teams actually need

Vertex captures the on-site evidence installer teams need for quoting, heat loss inputs, sound-check assessments, EPC and RdSAP evidence capture, and a cleaner route into installation.

Field evidence
  • Room measurements and room-by-room context
  • Emitter, loft, insulation, and window evidence
  • Photos grouped clearly enough for office and design review
Electrical evidence
  • Meter and cutout photos
  • Consumer unit evidence, fuse rating, and spare ways
  • Cable-run and siting context where the job needs it
Standards-supporting inputs
  • Site evidence that supports MCS 020(a) sound-check inputs
  • EPC and RdSAP assessor evidence where the job needs it
  • Scheme-related documentation support where applicable

Use Vertex upstream of your existing workflow

Vertex does not replace heat loss or design software. It improves the quality of the information coming off site so your existing workflow has better inputs to work from.

That matters for quoting, design review, sound assessments, installer handoff, and the wider job record your team relies on once more than one person touches the same property.
