LiU project aims to make Stockholm energy efficient

The goal is to make Stockholm an energy-efficient city. Louise Trygg, researcher in energy systems at the Department of Management and Engineering (IEI), will address the question of how industries, realty companies, and other major energy users can reduce power consumption. Several doctoral students will participate in this four-year project.

"It is challenging to explore the ways and means that can turn Greater Stockholm into a sustainable energy region," says Louise Trygg.

The assignment comes from the Swedish Energy Agency, a government authority. The work will be carried out in collaboration with the Agency and Fortum (a Finnish public listed energy company, which focus on Nordic and Baltic countries, Poland and northwest Russia), Vattenfall (a Swedish power company and a leading energy producers in Northern Europe), Eon (electricity and gas suppliers), the city of Stockholm, Energicentrum (Stockholm's resource for energy efficiency) and the County Administrative Board. The laudable goal is to create the world's first energy-efficient metropolis.

Louise Trygg is experienced in analyzing power consumption in the industrial sphere. Air compression, heating, hot water supplies, and industrial processes such as cooling, heating, drying are all potential areas for savings. Absorption refrigeration is another.

"If a distant heating system could be utilized for cooling—for instance in ice rinks and sport arenas—it would make an impact," Louise Trygg continues. She reckons that the energy consumption can be cut back considerably.

"We are familiar with European projects where industries have halved their power use," she says, " I am doubtful that that is possible throughout an entire metropolitan region, but we are setting high goals."

It is a question of retaining a helicopter view. An important part of the assignment is to retain a balance so that savings are not concentrated lopsidedly.

"We must also carry out a situation analysis, look at how control measures such as taxes, fuel prices and the electricity certificate system tend to affect usage."

The model of Stockholm created by the researchers will show the economic and climate consequences of the suggested actions.

The regional industries and realty companies are enthusiastic. The ultimate goal is that modifications in energy use will allow all parties—the energy suppliers, consumers and even the environment—to end up on the winning side.
