Alliander leader in circularity
When it comes to circularity, Alliander is one of the leaders in the Netherlands. Both in the primary process – in which as many materials as possible are reused – and in property. Five years ago, Alliander carried out a circular renovation of the office in Duiven and now the head office in Arnhem has also been renovated in a circular manner.
Circularity map for eight largest offices
Circular performance is also central in the use phase of these buildings. To measure this performance, Alliander and CFP Green Buildings mapped out the circularity of Alliander’s eight largest offices in the Netherlands. This exercise made clear how much raw materials are consumed and what possible measures there are for further improvements. The ultimate goal of the circular economy is to achieve raw material neutrality.
The energy transition and the climate agreement present us with a major challenge in making our gas, heat and electricity infrastructure future-proof. In addition to facilitating a sustainable society, Alliander also focuses on making its own operations more sustainable. Together with CFP, we have mapped out how we are performing in terms of circularity for our accommodation and facility services. This benchmark helps us identify where we can achieve even more sustainability.

Raw material consumption of 53 kg/m2 results in circular EPC B
The first step in this project was to calculate the consumption of raw materials in 2019. With a score of 53 kg of raw material consumption per m2, Alliander outperforms the reference of 85 kg/m2. This provides Alliander with the circular EPC B. The starting point for this calculation is the consumption of raw materials: all kilos of non-renewable raw materials entering and leaving the building are measured. This results in a score per m2 that can be benchmarked and used as an ambition. And that is of course only the start, because then measures have to be implemented to reduce the consumption of raw materials to zero.
Raw material savings on waste and electricity ensure substantial reduction
As CFP has an expert system with data from thousands of buildings, an accurate reference can be established. This is achieved by selecting comparable buildings and/or organisations per category and placing them in a reference group. This was used to determine how the consumption of raw materials at Alliander’s eight offices relates to both the average and best practice for all categories.
Striking features for Alliander were the low electricity consumption and the low volume of residual waste. During the renovations of the offices in Duiven and Arnhem, investments were made in energy-saving measures and solar panels to generate electricity. As a result, the consumption for these locations is very low. In addition, various campaigns for better waste separation – so as to reduce residual waste – have had favourable results. Less than 20 kg per FTE is discarded per year, which is ten times less than the average in the Netherlands.
Further savings on energy consumption biggest improvement potential
In addition to reviewing and comparing, the circular scan was also used to identify new measures. On the basis of the benchmark with the reference group, a number of buildings have been highlighted where possible savings can be made on energy consumption. To this end, CFP and Alliander have started carrying out energy wastage audits. During such an audit, possible energy waste is detected and the settings of the buildings are optimised, together with suppliers.
