Reporting on performance
Energy consumption per employee 7.4 MWh
Due to problems with data collection 5 locations with more than 40 employees are not included in the energy consumption statistics. In 2014 a total of 77 locations comprised of 11 928 employees reported energy consumption. Based on number of employees by the end of 2014, the environmental reports represent approximately 76 % of the Group. Total reported energy consumption for 2014 was 87.5 GWh. 23.4 GWh was consumed by locations that did not participate in the environmental reporting for 2013. Locations that did report energy consumption in 2013 but not in 2014 are include in the 2013 figures with 0.3 GWh. Together, the locations that reported for both years experienced an increase in the reported energy consumption of approximately 4.8 % compared to 2013. There is an increase in district heating from external suppliers of 422% compared to 2013, this is mainly due to reporting from locations that did not report last year.
Renewable energy on site has decreased to 2.9 GWh, down 29% compared to 2013. This is due to changes in use of the heat pump at Høvik which was earlier used both for heating and cooling, but which is now only used to produce heat. Water for cooling, temperature 7-9 degrees, is now pumped directly from the sea. Specific energy consumption decreased to about 7.4 MWh per person in 2014 – down 10,0 % from 8.2 MWh per person in 2013. This decrease in consumption per employee is affected by an improved energy measuring process for one large location that has reported too high figures in 2013, energy saving initiative at several locations, and underreporting by some of the locations that are reporting for the first time.
Specifically ordered renewable electricity off-site was 10.1 GWh in 2014 increased from 3.0 GWh in 2013. The locations reporting for the first time in 2014 are the main contributer to this significant increase in consumption of renewable electricity off site. Non-renewable energy produced on-site at the reporting locations increase by about 14 % compared to 2013. This increase relates to the consumption of 6.3 GWh produced by combustion of gas on site at the locations reporting for the first time in 2014. Together, the locations that have reported consumption of gas for both years have a decrease of 33.3 % in their consumption compared to 2013. The main contributors to this substantial reduction is the test site facilities in Groningen that has not been using their high natural gas consuming test facilities in 2014, and the Barendrecht office building where significant improvement to the controls of the HVAC (Heating, ventilation and air-conditioning) system has been implemented.
