Mattheos Santamouris is a Professor of Energy Physics at the University of Athens. Over the last
decade, he has been involved in measurement and analysis of urban heat islands in Athens. His
pioneering work includes the development of regionally suitable cool materials and use of
advance thermochromic coatings for urban surfaces. Professor Santamouris is the Editor in Chief
of the Journal of Advances Building Energy Research, and Associate Editor of the Solar Energy
Journal.

Dr Paul Berdahl is semi‐retired and is investigating how surface roughness reduces the solar
reflectance of materials, the soiling and weathering of roofing materials and the destruction of air
pollutants by photocatalytic oxidation using the semiconductor TiO2. Prior to his retirement in
2005, he worked on synthesis of high‐temperature superconducting YBa2Cu3O7 tapes (with R.
Russo and R. Reade). World record critical current values were achieved in 1992. Other topics
were infrared luminescence of semi conducting InSb, infrared radiative cooling, long wave
radiative transfer in the atmosphere, and the availability of the solar radiation resource.
