Energy mapping for Norconsults 18 offices in Sweden (English)
Abstract [en]

In Sweden, June 1, 2014, law 2014: 266 on energy mapping in large companies came into force. An energy mapping is a map of the company's energy use. It describes what type of energy carrier is used, electricity, district heating, fuel, and how big the consumption is. It also describes the part in which this energy is used within the company, for example in business or transport.

The purpose of making an energy mapping is to get an overview of the consumption of energy in the company and to find possible actions to reduce the consumption and the cost for energy.

This energy mapping deals with Norconsult's 18 offices operations in Sweden. The project also includes Norconsult Fältgeoteknik AB, a subsidiary of Norconsult.

The result from the energy mapping was that the total energy consumption for the company 2016 was 3 588 MWh. The total cost of all consumed energy is estimated to approximately 3 100 000 SEK in 2016. The energy consumption of the company is divided into three different uses, district heating, electricity and transport.

From the result the total use for the transport accounts for 56 percent of total consumption, 26 percent of transportation is Norconsult's consumption of gasoline and 20 percent is Norconsult Fältgeoteknik's consumption of diesel. 21 percent of the total consumption is electricity, and 20 percent is district heating. 

Based on the overall energy use, examples for energy reductions have been made for the various areas, which has given an opportunity to improve energy use at the company Norconsult. The suggestions are presented below. 

The Gothenburg office uses district heating and district cooling. For several months in 2016, these systems were running simultaneously. The conclusion is that there is a significant savings possibility, as there is no need for costing to fix the problem, just an adjustment of the control of heat and cooling.

Monitors and computers are often in sleep mode during evenings and weekends, which causes unnecessary energy. By establishing routines for shutting down screens, computers and printers, it can make energy saving of 2.4 percent of total electricity consumption.  

In 2016 Norconsult personnel flew 159 times from Stockholm to Gothenburg. This resulted in an increased energy consumption of 13.18 MWh compared to if the travels were made by train. This amount stands for 0.37 percent of the total energy consumption, which is not very much. However, air transport consumes energy through combustion of aviation fuel, while energy consumption for trains is by electricity. Electricity is a much purer source of energy emissions, which results in a reduced environmental impact. The conclusion it that it is possible to save both money, time and reducing the negative effect on the environment by switching from flights to rail transport.
