EPRA Sustainability Best Practices Recommendation (sBPR)

Castellum’s tradition of sustainability reaches far back into the company’s history. Right from its founding, we have worked on energy efficiency and certification. Over time, the sustainability issue has grown and several perspectives have been added. At Castellum, we see ourselves as a builder of communities. In this light, our strategy is to take sustainability issues seriously from a financial, ecological and social perspective. Our sustainability efforts are integrated into everything we do, and a natural part of our daily work.

Sustainability indicators under EPRA

Castellum’s reporting of its sustainability efforts follows the guidelines from the Global Reporting Initiative (GRI) Standards: Core option. The GRI’s industry-specific supplements for the construction and property sector have been taken into account. The sustainability report is presented annually and sources are given for the data, assumptions and conversion factors used within the framework of the report. No material changes regarding the organization or supply chain occurred in 2019.

EPRA Performance Measures

Castellum reports the company’s key sustainability metrics based on the European Public Real Estate Association (EPRA) Sustainability Best Practices Recommendations (sBPR), third version, September 2017.

Castellum reports key sustainability metrics for all 28 of the EPRA’s sBPR performance measures. Key metrics are reported for energy, greenhouse gas emissions, water, waste, and environmentally certified buildings as well as corporate governance and societal aspects.

EPRA Overarching Recommendations

Organizational boundary

Castellum limits its reporting to properties where we have operational control in accordance with the principles of the Greenhouse Gas protocol. Operational control was selected since it provides Castellum with the best conditions for reporting the statistics and data that Castellum can directly influence. Properties where the customer is responsible for agreements regarding energy and water deliveries and waste removal are thus excluded. Nor does Castellum own measurement data in cases where the customer is responsible for the agreement, and it is therefore difficult for us to report that type of data.


For properties Castellum owns and manages, we work actively to gain access to the relevant measurement data. Having access to measurement data is important for Castellum, as it creates conditions for proper, efficient technical management in our buildings. At present, Castellum has excellent access to measurement data for nearly its entire portfolio. The size of the share of properties included in the respective indicators is shown next to the respective key metrics. Note that the share of potential objects to report under absolute figures for the respective years includes objects sold during the year in question, excluding land.

Castellum does not, however, have access to all of the measurement data for all its properties. We are primarily lacking measurements of waste owing to the fact that the waste management contractors cannot provide statistics for all properties. Measurement data is also missing for energy and water. This is due to changes in the portfolio from purchases and sales of properties as well as development properties, which makes access to the relevant data more difficult. Castellum works continually on improving access to the relevant statistics.

In total, Castellum owned 632 (647) properties at the end of 2019.

Estimation of landlord-obtained utility consumption

No data has been estimated; all measurement data reported has been measured and assured.

Third party assurance

In accordance with ISAE 3000, Castellum’s Sustainability Report under the GRI Standards has been subject to a limited assurance engagement by Deloitte AB. The Sustainability Report includes key sustainability metrics in accordance with the EPRA’s sBPR performance measures. See the assurance report in Assurance report sustainability.

Boundaries – reporting on landlord and tenant consumption

Castellum reports only energy purchased by the landlord (i.e. Castellum). It does not therefore report tenants’ own electricity consumption, since in the main we do not have access to those statistics. Castellum cannot directly influence tenants’ electricity consumption, which makes the statistics to some extent less relevant.


Castellum calculates key intensity metrics through division by the total floor area of the buildings; this is the most widely accepted method in Sweden for comparing energy use and resource consumption.

Castellum uses Swedish Meteorological and Hydrological Institute (SMHI) degree days to normalize energy for heating.

Segmental analysis (by property type, geography)

Castellum reports sustainability data divided into the following building types: offices and logistics. Since Castellum owns properties primarily in Sweden and a very small share in Denmark and Finland, reporting the statistics by geographical division is not relevant.

Disclosure on own offices

Castellum’s own offices are reported separately in EPRA: Sustainability performance measures – Environment.

Narrative on performance

To read more about the changes from 2018 to 2019 regarding key environmental metrics and the savings achieved, see EPRA: Sustainability performance measures – Environment. No adjustments have been made to the data reported. Decisions on community engagement are taken in the respective regions.

Reporting period

Reporting for the respective years recognized in the EPRA table refers to calendar years (i.e. January 1 to December 31).


Castellum’s materiality analysis is reported in Background data for GRI disclosures.
