Based on the GRI CRE3 indicator
Total quantity of direct and indirect greenhouse gas emissions per square metre and per year.
The surface area used for the denominator corresponds, for office buildings, to the surface area of the superstructure.

Notes
1 The like-for-like analysis is conducted on the consumptions of the common technical equipment of multi-tenant buildings and all the
consumptions of single-tenant buildings.
2 The total greenhouse gas emissions for offices detailed in this table come from heating gas. It is based on the KPI “total consumption of energy
coming from fuels”.
3 The conversion rates used are the following:
A. conversion of electricity consumption into primary energy: 2.5;
B. conversion of gas consumption into primary energy: 1;
C. the CO
2
emission factor stands at 260g/kWh for electricity (source: ADEME) and 251g/kWh for gas (source: CWaPE).
4 Cofinimmo has no influence on the CO
2
emissions related to private consumptions, i.e. consumptions of single-tenant buildings and of private
areas of multi-tenant buildings.
Notes
1 The like-for-like analysis is conducted on all the buildings’ consumptions (multi-tenant and single-tenant).
2 The only supply source is tap water.
3 The water consumed feeds the air-conditioning installations, sanitation systems and the kitchenettes.
4 Cofinimmo’s influence is limited to the common installations of the multi-tenant buildings of which the Property Management is taken care of by
Cofinimmo Services.
