Property & Portfolio Managers
Protect asset value, asset by asset.
Listed and non-listed owners protecting asset value, who want a clear, costed sustainability plan they can execute asset by asset.
How it works
One Building Vault, two modules. Every building scanned, improved and proven, in four steps.
Module 1
Renovation
Goes deep into energy uplifts and decarbonisation, plus seven further topics such as water and pollution. You see which improvements and CapEx to fund, building by building.
Module 2
Certification
BREEAM In-Use certification prepared by AI from the same record, then checked and signed by licensed assessors.
Drop them into the Building Vault
Every piece of evidence, kept in one place. Our agents read every page: drawings, installations, meter data, certificates. No templates, no retyping.
Minutes later, you see where the building stands
Every BREEAM credit scored, plus the energy label, sustainability impact score and CRREM carbon pathway.
Then it tells you what to do about it
A yearly improvement plan: measures ranked by cost and effect, timed with your maintenance plan. Re-planned every year.
Licensed experts review and sign
A licensed assessor checks every answer against its source and signs. Certificates and investor data come from the same record.
Example
10 assets. One CapEx plan.
Every investment proven.
A Dutch and German portfolio needs a renovation plan for every building, one CapEx budget for the investment committee and BREEAM In-Use certificates. Here is the consultant route next to Sustainix AI.
