Naomi Durkan pursued a M.SC Advanced Environmental and Energy Studies at the University of East London and Centre for Alternative Technology, and graduated in January, 2007.  Naomi focused on greenroof maintenance issues, wildlife roofs, and greening the urban environment. See her Green Roof Maintenance Questionnaire survey posted on livingroofs.org in English here, and in German here.  Naomi said, "Your knowledge, experiences and opinions as building/ facilities managers are extremely valuable and often overlooked. I am conducting this research as part of my thesis which looks at issues to do with roof maintenance. It is particularly concerned with Green Roofs which are often advertised as low maintenance, but no real assessment of how they actually perform has been done. The needs and concerns of those who maintain them are often left unconsidered when the roof is specified. The results of this research can be used to raise awareness amongst the construction industry, architects and designers about specifying appropriate roofing systems and long term maintenance implications of design decisions.  The questionnaire takes a maximum of 10 minutes to complete and I need a wide variety of responses, so no matter what type of roof you manage, your time would be greatly appreciated."  Contact Naomi at:  naomidurkan@gmail.com.

Christophor Faust holds a PhD in the Interdisciplinary Engineering Department of Texas A&M University from August, 2005.  A nuclear engineer by trade, he has been doing advanced building energy design work for a decade now. Christophor's PhD work is in “Passive Environmental Engineering” as it relates to the built environment.  "My research deals with bio-mimicry and passive thermal engine technology, and I have use it to create two living, breathing, thinking environmental systems, which are called a Hauses, or sustainable homes.  These dwellings are two of the safest, healthy, energy efficient and all-around sustainable man-made structures ever built, and they both have green roofing systems.  My professional interests are in global sustainability, the built environment and balanced bio-climatic building energy design.  As it turns out, I don’t know anything about plants; -o …except that they consume global greenhouse gasses, produce pretty flowers and when utilized within an “interactive” building energy design strategy, can eliminate the need for conventional heating, cooling and dehumidification systems in the home.  I think that Green Roofs are going to be a very big part of the solution to our global environmental problems, and look forward to meeting other like minded student/professionals who want to be a part of making that reality come true. I have a brief associated with my research work/technology that I will send anyone who is interested."  Contact Christophor at:  979.587.0839 or c-faust@tamu.edu.
