How does it feel to receive this award?
– It feels great and means a lot to get such a positive feedback as it validates the effort and energy that is put into the work. Being an early-stage researcher is not always easy as most of the times it feels like you are a piece of a puzzle that is navigating in the dark to find where it fits. I am quite luck because I have a number of people who willingly invest time in me and provide mentorship. This award means a lot because it shows that with support one has a chance to grow and flourish. Therefore, I do not see it as an individual achievement, it is an award for the energy systems group and for our department.
What is your research about?
– My research has mostly revolved around building energy efficiency with focus on resource-efficient ventilation processes. This is because buildings account for the largest share of energy use and heating ventilation and air conditioning systems take about 50% of that share. With my research, the goal has been to explore alternative air distribution and ventilation strategies that promote thermal comfort and good air quality at a reduced energy use. Thus, my PhD studies ("Experimental study of an intermittent ventilation system in high occupancy spaces" ) proposed and explored a novel ventilation strategy that optimized intermittent airflow in high occupant spaces to enhance thermal comfort and air distribution. I have expanded my research by studying performance assessment on basic fluid mechanic principles in microclimate ventilation systems, in which we distinguish between ventilations systems that service the whole room (dilution systems) and those that focus on a specific space in a room (examples are common in vehicles, planes and now being introduced in buildings as personalized ventilation). Within this research we have introduced a new concept called “entrainment mixing factor”, which is a mathematical framework applied when assessing the level of pollution in the air that is delivered to be inhaled by people. Additionally, I wish to expand my research palette to include solar energy in buildings and how we can securely connect to the electricity grid.
