Division of Building Physics


As the main part of the building stock is already built, it is important to improve these buildings as much as possible during conversion and renovation so that they best meet the same requirements that are placed on new buildings used for different purposes. However, the improvement must take place without sacrificing antiquarian, aesthetic, architectural and other properties that must be preserved in the existing houses.

We apply and develop calculation models adapted for PC computers.

National and international networks are essential for taking part in ongoing activities inside and outside Sweden, and to influence our surroundings. The division is therefore active in, among others, International Council for Research and Innovation in Building and Construction (CIB), the International Energy Agency (IEA) and the International Standardization Organization (ISO) and has contacts with universities all over the world. Within Sweden, we maintain contacts with a large number of companies, authorities, financiers and industry organizations.

Our research results in basic building technology and building physics are combined with others' research results in our courses in bachelor education, which will provide the students with stable foundation in the latest research related to the subject area. We carry out most of our courses together with the Division of Building Services.

The Division of Building Physics will start working on a large European project, called COLLECTiEF, together with thirteen other institutes from six European countries.  COLLECTiEF was approved with a top rank in a very competitive H2020 call, B4E, and a score of 15 out of 15.

In COLLECTiEF we are going to implement, test and qualify an energy management platform based on Collective Intelligence (called CI-DSM) to increase energy flexibility and climate resilience in buildings and urban areas. We aim at increasing the communication between buildings, energy systems and their components without jeopardizing user privacy and data security while keeping the required IT solutions simple and not expensive.

Prof. Vahid Nik is the Scientific Coordinator of COLLECTiEF and leads the project at LTH. 

The basic idea of CI-DSM is explained in this open-access article (in English)
