Discussion Topic






What PED definitions/concepts do you know? Are there any relevant definitions/concepts that you think we should take note of? (Aim: collect ideas on existing concepts at the national, European and international levels.)


Per Sieverts Nielsen


Board 1



What do you think are the main challenges, shortcomings or gaps in the existing definitions/concepts? (Aim: identify the main aspects to be addressed/improved in the development of the PED definition framework.)


Adriano Bisello


Board 2



How do you see the applications of a PED definition framework? (Aim: identify the potential applications. The potential uses will directly affect the content of the definitions e.g. qualitative vs. quantitative.)


Caroline Cheng


Board 3




How to account for different boundary conditions (e.g. climate, land use, built form, etc.) in the PED definition framework? (Aim: help us to develop a universal framework that can be used in different districts, cities, countries and world regions.)


Vicky Albert- Seifried



Board 4



How to treat mobility in the calculation of the energy balance for PEDs? Should it be included? If yes, how? If not, why? (Aim: help us to get some ideas on the treatment of mobility in the PED definition framework.)


Pekka Tuominen


Board 5




What do you expect to see in the framework of PED definitions? What are the crucial dimensions and components? (Aim: help us to understand what the important considerations are in the development of the PED definition framework.)


Andrea Gabaldón



Board 6


Andrea Gabaldón Moreno, Adriano Bisello, Caroline Cheng, Francesco Reda, Per Sieverts Nielsen and Vicky Albert-Seifried.
