One or more phd stipends in hygrothermal building physics with specific focus on hydrophobization (SBi-17066)

At the Faculty of Engineering and Science, Danish Building Research Institute (Department of building technology and management) one or more PhD stipends in hygrothermal building physics with specific focus on hydrophobization are open for appointment from 1 October, 2017 or as soon as possible thereafter. The position is available for 3 years. Urban environments in Danish and many European cities are characterized by buildings with masonry facades. Conservation of these buildings requires that the brickwork is maintained and that the buildings' energy and indoor performance is improved to fit the demands of the future. Internal insulation is often the only way to improve the thermal insulation of older buildings with solid masonry, as it is not acceptable to change the appearance of these buildings. Internal insulation, however, can potentially lead to moisture-related damage in the building as the insulation changes the hygrothermal conditions of the original structure and makes it more vulnerable to e.g. driving rain, biological growth and frost. Therefore, there is a need to understand and reduce the risk of damage when using internal insulation. Hydrophobic treatment of the external surface is an option that should be investigated further.


The PhD project is part of a larger project "Moistur -safe Energy Refurbisment of Historic Masonry Walls ". This national monitoring project runs 6 years and the purpose of it is to contribute to the knowledge about how to refurbish buildings with masonry walls in a moisture safe way and achieve energy savings.

The project focuses on establishing this knowledge with specific focus on how the performance of a facade is changed with hydrophobic treatment, which is investigated either as an independent measure or as a supplement to internal insulation.
Hydrophobic impregnation is not well-researched, and experience based knowledge is especially missing with modern products and on masonry in Denmark.

This PhD study is running in parallel with a major EU H2020 project "RIBuild - Robust Internal Thermal Insulation of Historic Buildings", enabling a good international cooperation and network.

The PhD study includes activities like:

  • Literature studies on hydrophobic treatments
  • Planning of field monitoring, including selection of test buildings, surveys and selection of refurbishment systems as well as preparation of test plan
  • Laboratory investigations that are used to understand the moisture transport mechanisms in more detail, including variation in bricks, mortar and masonry, insulation materials and hydrophobic treatments. In addition, selected solutions will be exposed to aging tests.
  •  Numerical simulations for planning of the experimental set-up and parameter analysis
  •  Collecting experience about existing constructions with internal insulation and facades with hydrophobic treatments
  •  Dissemination of the results in scientific articles and as conference contributions

You are expected to have the following prerequisites:

  • Strong theoretical knowledge in building physics, including knowledge about construction materials and heat and mass transport processes in porous materi
  • Good oral and writing skills in English

It is an advantage if you have a good knowledge of:

  • Chemistry and surface physics
  • Use of simulation tools for analysis of heat and moisture transport in materials and in building structures
  • Experience with experimental measurement methods
  • Analytical skills
  • Good communication skills in Danish

In your application, you must argument that your qualifications are relevant to the described project description and also your motivation for the position. Also add a short description (½-1 page) of what you would like to pay particular attention to in the project.

Further information on the position can be obtained by contacting Research Director Ruut, telephone 9940 2367.

PhD stipends are allocated to individuals who hold a Master's degree. PhD stipends are normally for a period of 3 years. It is a prerequisite for allocation of the stipend that the candidate will be enrolled as a PhD student at the Doctoral School of Engineering and Science in accordance with the regulations of Ministerial Order No. 1039 of August 27, 2013 on the PhD Programme at the Universities and Certain Higher Artistic Educational Institutions. According to the Ministerial Order, the progress of the PhD student shall be assessed every six months. It is a prerequisite for continuation of salary payment that the previous progress is approved at the time of the evaluation.

The qualifications of the applicant will be assessed by an assessment committee. On the basis of the recommendation of the assessment committee, the Dean of the Faculty of Engineering and Science will make a decision for allocating the stipend.

For further information about stipends and salary as well as practical issues concerning the application procedure contact Mr. Jens Balslev, Head of Secretariat at The Danish Building Research Institute, email:, phone: +45 9940 2211.
