Walk the Talk - District heating and cooling

Turning words into action – walking the talk – is required in our work and commitment to questions of sustainability. At Linköping University we take these words extremely seriously, with our measures to ensure sustainability and efficient energy use.

We have chosen to showcase this work in an exhibition of the same name – Walk the Talk – at both Campus Valla and Campus Norrköping.

The exhibition is public, free of charge, and accessible all year round.

This is how positive energy is created

Did you know that Linköping University is heated by district heating? In Tekniska Verken’s cogeneration plant, your household waste that has not been recycled, residues from the wood industry, and more are incinerated. Resources that would otherwise be lost are thus turned into both heat and electricity.

Energy-smart district cooling

Location: Campus Valla, District cooling facility outside the C Building

District cooling is both a climate-smart and energy-smart way to create a pleasant indoor temperature in, for example, offices and server halls. Excess heat is used, and converted to cooling, and this takes place without needing to use environmentally hazardous cooling agents, while consuming less electricity than traditional cooling devices. The technology is simple. Water is cooled in the facilities of the energy producer with the aid of cooling equipment, and then distributed through a network to each property that is connected. Here, a district cooling center controls the transfer of cooling to the property through a heat exchanger. The cold water is pumped out from the heat exchanger and distributed to cooling units in the property.

Research area - Energy Systems

Energy

More efficient use of energy requires a systems perspective: an action that reduces carbon dioxide emissions in one place may multiply emissions in another. LiU researchers study energy systems in buildings, locally, regionally, and in industry.

Walk the Talk

Walk the Talk is an exhibition showing how LiU turns words into action when it comes to active work with sustainability and energy efficiency. More information is available at the stations located on Campus Valla and Campus Norrköping.
