Maria Kolokotroni



Academic Career

I studied for an MSc in Environmental Design and Engineering at the Bartlett School, University College London (UCL). I stayed at UCL to carry out a PhD on the 'Thermal Performance of Housing' and further on for a post-doc on a two year project to develop environmental design guidance for research laboratories. I then moved on to the University of Westminster for a three-year post-doc on an EPSRC funded project dealing with Moisture in Residential Buildings. I joined Brunel in 1998.

Industrial Career

I worked for five years at the Building Research Establishment, Garston in the Indoor Environment Division. My research work focused on the application of natural ventilation strategies in office buildings as well as other energy and indoor air quality related issues in non-domestic buildings.

Research area(s)

  • Urban heat island
  • Urban microclimatic characteristics
  • Carbon emission reduction
  • Sustainable heating and cooling energy technologies
  • Ventilation
  • Low energy building design
  • Operational use of buildings
