About the position

For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.  

The Department of Energy and Process Engineering (EPT) has a vacancy for a PhD scholarship with the sustainable energy system group (SES). The SES group has a strong background in indoor environment, HVAC and energy in buildings. The PhD is part of the SusWoodStoves knowledge-building project lead by SINTEF Energy Research in collaboration with Norwegian space heating industry. The objective of the SusWoodStoves project is to evaluate and increase the sustainability of space-heating using wood stoves by improving the stove, the building integration and through value chain optimization, i.e. a topic of relevance for many countries.

About the position
We have a vacancy for a 3-year PhD in the field of data-driven analysis of the real building performance using wood stoves. Heating using bioenergy is important in Norway, as well as many other countries, and wood log combustion has a long tradition accounting for about 12% of the domestic heating. The PhD aims at evaluating two interrelated effects, mainly using data-driven methods on detailed field measurements:

  • Grid interaction and resilience: Using wood logs is important for security of supply in Norway, where we today rely heavily on the electricity grid to deliver the needed space-heating for houses. With a high nominal power, wood stoves can significantly reduce power peaks in the electricity grid, prevent blackouts and act as backup heating system (i.e., resilience). In a context of increasing electricity use in households, including electric cars, reducing peak electric power is strategic as it enables to prevent or postpone large investments to reinforce the distribution grid. 
  • Thermal comfort and energy performance gap: Preliminary measurements have shown that occupants apply a lower indoor temperature in average if they can quickly re-heat the building using a wood stove after a period at lower indoor temperature (also related to alliesthesia). Thermal comfort with a stove should be understood in more details in order to evaluate the real energy performance of space-heating using wood stoves (i.e., performance gap and prebound effect). 

 


These two effects are closely related to the occupant behavior. Consequently, the research work relies essentially on data-driven analysis of collected data, including detailed field measurements and questionnaires (meaning statistical analysis of data series). The research is original as it will be based on collected data from smart electricity meters (AMS) and measurements using new wireless indoor environment sensors, coupled with occupant behavior knowledge. 

The Head of Department is Professor Terese Løvås. The day-to-day position management and supervision is by Associate Professor Laurent Georges. The SusWoodStoves project is managed by the Dr. Øyvind Skreiberg, Chief Scientist at SINTEF Energy Research.
