Sustainable buildings and Energy

KTH activities such as education and research require premises such as labs, offices and teaching areas. KTH works continuosly to reduce its energy use based on set climate targets, which is done in collaboration with the property owners.


During the summer

During the summer and before the holidays, we can all contribute to reducing KTH's energy use. Every kWh counts!

In particular, keep in mind to:

  • Switch off your KTH work computer and computer monitor and any other devices at your workplace before you go on holiday.​​
  • Turn off equipment in standby.​
  • Turn off all lighting (except emergency lighting) in unmanned premises.​
  • Unplug the charger before you go home.​
  • When you're at the office, don't keep windows open, only ventilate briefly if necessary. Remember to close the window afterwards.

Energy plans for buildings

Energy saving measures by KTH and Akademiska Hus in 2023

KTH and Akademiska hus collaborate on buildings and energy issues. Examples of joint measures are:

  • Operational optimization of ventilation, temperature and lighting
  • Night walking: Energy monitoring of the activity during the evening
  • Degree projects with a focus on specific buildings on the KTH Campus
  • Implementation of tests to advance the switching off of lighting in certain corridors

For example, during the night walk carried out in the spring of 2023, some areas for improvement was noted. Fume-hoods were not closed, lights were not turned off, windows were open and screens in meeting rooms were not turned off.

During the summer of 2023, buildings on KTH Campus were closed and operating hours were adapted to a lower occupancy rate in buildings that were open.

2022 energy and results

KTH's sub-targets for sustainable buildings and climate impact

Sub-target results: KTH's climate impact from energy use in comparison with 2015
​​​​​- Reduced by 24 percent (from 584 CO2e to 445 CO2e) per annual workforce
- Reduced by 23 percent (from 167 CO2e to 128 CO2e) per full-year student
- Reduced by 20 percent (from 7.7 CO2e to 6.2 CO2e) per square meter

The share of renewable energy was 96% of the total energy usage at KTH. In total 3599 kg CO2e per MWh (4 ton CO2e) was produced by solar energy from buildings at KTH.

Water consumption 2023: 162966 m3 (0,58 m3/m2), an increase of almost 140 % compared to 2022

The property owners (see below) anually produce an energy plan that describes the measures taken to reduce energy use in the buildings. The Energy Plan 2022 (pdf 255 kB)  describes the measures that have been implemented by Akademiska hus during 2022, which relate to electricity, heating and cooling.

Collaboration with property owners

KTH operates on 5 campus areas in the Stockholm region. KTH does not own its buildings, but rents them from the property owners Akademiska Hus, Hemsö and Samhällsbyggnadsbolaget. Close cooperation with them is a prerequisite for carrying out the work to ensure that the buildings are sustainable and climate-adapted in accordance with KTH's sustainability and climate goals.

KTH collaborates with Akademiska Hus on a strategic level through the so-called "Strategic Collaboration Forum". Within the framework of the forum, goals have been set regarding collaboration around education and research, as well as campus-related issues. An update of the goals takes place annually in December, with the CEO of Akademiska Hus and KTH's headmaster.

Within the framework of the collaboration with Akademiska hus, the following projects and measures have been taken in 2022:

  • Research and education projects that KTH and the property owners collaborate on in the Live-In Lab: Completed R&D projects | KTH Live In Lab
  • Research and education projects that KTH and Akademiska Hus collaborate on: Conceptualization of AI in building operations in the form of Indoor climate as a service.
  • 'Green lease' for building 43:35 Bergs (as part of ongoing research project).
  • Modernization of the KTH Chemistry building began. Expected to be completed in 2024.

Additionally, collaboration takes place in the ongoing administration on various substantive issues, e.g. energy, renovations, waste, biological diversity, etc.

Indoor climate

KTH has signed a 'green lease' agreement with Akademiska Hus for house 43:35 Bergs, where the project "indoor climate as a service" is included. In this project, Akademiska Hus will use artificial intelligence to control the indoor climate. The project is temporarily paused.

Within the research collaboration between KTH and Akademiska Hus, an industrial doctoral student has had a new business model developed and implemented with the aim of providing an agreed indoor climate with the lowest resource use based on a suitable level of digitalisation. The research has so far resulted in three research articles:

Energy mapping

For every building at KTH with Akademiska Hus as landlord, there is a detailed energy mapping. This includes, among other things, proposed measures to reduce energy consumption.

Technology platform

In the technology platform, there are feature requirements, e.g. requirements for U-value on walls/windows for energy-efficient construction. The technology platform's document is available on Akademiska Hus' publication page: All publications | Akademiska Hus

Environmental construction

In the case of new constructions and redevelopment, KTH demands that environment and sustainability aspects are included in the project. The environmental certification Miljöbyggnad sets requirements on the building's environmental performance and energy consumption. Of the buildings KTH uses, nine are certified according to Miljöbyggnad; four as gold and five as silver.
