# ESG for buildings and infrastructure

> Improving a building's ESG KPIs starts with reliable data: metered consumption by source, correct floor areas and the history of works. With the BIM model and a digital twin this data can be read by floor, zone and system: you see where energy is used, compare measures by cost and saving, and produce the indicators required by the EPBD, CSRD (ESRS E1), the EU Taxonomy, GRESB and public tenders. BIMON prepares models and data; energy certificates and sustainability statements are still signed by certifiers and auditors.

Banks, investors, EU rules and public tenders ask for more and more environmental data on buildings. We take it from meters, the BMS and maintenance, link it to the building's BIM model and use it to choose retrofit measures and to report, with the source of every number.

## Who asks for ESG data

EPBD, Directive (EU) 2024/1275: renovation of the worst 16% of non-residential buildings by 2030 and 26% by 2033; zero-emission new buildings (public from 2028, all from 2030); life-cycle GWP (new buildings over 1,000 m² from 2028, all from 2030). CSRD, ESRS E1: energy by source, Scope 1 and 2 emissions, transition plan. EU Taxonomy and green loans: energy class, measured consumption, verifiable documents. GRESB: data coverage, intensity per m², trend. Italian CAM criteria (2022): environmental requirements checked in design and on site.

## How we work

1. Measure: consumption from meters, bills and the BMS mapped to the BIM model. 2. Locate: where and when energy is used. 3. Simulate: measures compared by cost, saving and timing. 4. Report: indicators with source and history. BIMON prepares models and data; energy certificates and sustainability statements are signed by certifiers and auditors. Projects: Prato Hospital (digital twin for energy and maintenance, Impresa Pizzarotti), Trieste trigeneration plant (Hera), CERN Science Gateway, ECMWF data centre.

## FAQ

**I need to improve the ESG KPIs of my buildings: where do I start?**

From the data you have: bills or meter readings for the last 12-24 months, the list of buildings, floor areas and energy certificates. With these we build a consumption and emissions baseline per building, see where to act first and choose which indicators the people asking actually need.

**What do BIM and digital twins have to do with ESG?**

They give data a place. Consumption mapped to a floor, a zone or a system in the model can be explained and reduced; an annual total on a bill cannot. The model also provides correct floor areas and quantities, which are needed for per-m² indicators and for LCA.

**Do we need a full digital twin to begin?**

No. You can start with the meters and a simplified model of the buildings, limited to floor areas, zones and main systems. The digital twin is extended when you need real-time measurement or maintenance management.

**Do you issue the energy certificate or the sustainability statement?**

No. We prepare the models and data needed by those who sign them, that is the energy certifier, the people drafting the statement and the auditor, with the source of every number. That makes the checking quicker.

**What does the new EPBD ask of existing buildings?**

For non-residential buildings it introduces minimum performance thresholds: the worst 16% must be renovated by 2030 and the worst 26% by 2033. To know where a building stands you need measured consumption and correct floor areas.
