SUSTAINABILITY REPORT 2019 ENERGY CONSUMPTION ENE
RGY OPTIMIZATION Hedin Bils use of energy is one of our foremost sustainability risks. Energy optimization is therefore an area where we’ve actively chosen to conduct activities that decreases our effect on the climate. We are continuously measuring and following up on the total consumption of electricity, district heating- and cooling, gas and oil. On our different facilities the most considerable sources of consumption are heating, lighting, ventilation, baseloads and cooling. The mix of district heating varies greatly from location to location, this is why we use a mean value of approximately 30% fossil and 70% renewable as we calculate our climate impact. To be able to create the right circumstances for our facilities to actively reduce their energy consumption we are conducting an energy optimization program since 2016. The program is a joint effort with an external partner that strives to significantly reduce the energy costand usage at our sites through optimizing the daily operations and other profitable measures. In addition to lowering the energy costs the cooperation also aims to improve the indoor climate and reducing the external environmental impact of our personnel. During 2017 we started the first energy cooperation’s and as of early 2018, six pilot facilities were active in the joint effort. An additional three were activated in latter half of the year. The majority of the now 31 active sites were launched in 2019, all with the main focus to reduce the energy consumption and thereby reduce our external environmental impact. The savings within the bounds of the respective energy cooperation (site) is calculated through the difference between current consumption per month and the consumption during the base year. The base year is the upcoming 12 months after the start of the cooperation. For example, Stockholm Akalla, that were started in September of 2018, the base year period is September 2017 to August 2018. General actions concerning ventilation and heating that has been conducted up to this point in the sites where the cooperation has been going on for a while and where the results can be determined is: the adaptation of uptime regarding the operation lifetime span, adjusted intake temperatures, adjustment of flows after current needs, adjusted start/stop temperatures for night heating- and cooling as well as adjusted lead-up curves (for temperature) for heating systems, changed pump stops for ground heating (amongst other things), adapted indoor temperatures (reduced top temperatures). In order to minimize the risk of a decrease in indoor climate quality the changes are always carried out gradually. The continuation of the improvements will need to be conducted henceforth to further increase the energy performance.

ANALYSIS The reason why our total use of energy (kWh) was reduced with 5.8% in 2019 is mainly through our ongoing energy optimization programs. During 2019 22 new collaborations was started in addition to the preexisting nine already active. We find that the sites active during 2019 collectively generated savings (compared to the base year) equivalent to 2,329.5 MWh of electricity respectively 4,358.8 MWh of district heating with a combined net savings equivalent to 4,860 (kSEK). The energy usage in kWh/m2 was reduced by 7.8% compared to 2018, because of the slight increase of the total m2 in 2019 used by our operations. The amount of electricity from renewable sources increased to 92.3%, resulting in lowered emissions and less negative climate impact. As pre-existing energy contracts were eliminated in early 2019, new contracts were signed for the entirety of our operations in Sweden and Norway. Since May 2019 vi are buying 100% of our electricity from renewable sources. 7.7% relates to electricity produced in accordance to the Nordic residual-mix of their period January-April 2019. TARGETS Our target is to reduce our total energy consumption (kWh/m2) with 3% in 2020. The target is reached through the active participation of our sites in the energy optimization project that up to this point has resulted in savings. ENERGY CONSUMPTION kWh/m2
