  • Ecological urban design through material & energy flow analysis and life cycle assessment : from an architect's perspective
  • 2010
  • Ingår i: The 6th International Conference on Urban Regeneration and Sustainability.
  • Konferensbidrag (refereegranskat)abstract
    • The process of ecological urban design was studied through the perspective of  Material/Energy Flow Analysis from an architect’s viewpoint. The study examined how to control and adjust the production, transportation, distribution and consumption of material and energy flows in built environment systems, and how to analyse the relevant ecological design methods. Two environmental methods were used, Material/Energy Flow Analysis as the main method and Life Cycle Assessment as a parallel method, to analyse the ‘integrated efficiency’ of material and energy utilisation in the built environment and its significance for sustainable design. The analysis was applied to two cases: Material Flow Analysis of  household wastewater treatment; and Energy Flow Analysis of energy for heating and cooling buildings.

  • Study of Three Seveso II Reports in Sweden : Are the Results Presented in the Reports Good Enough?
  • 2007
  • Ingår i: Proceedings of the 17th Nordic Research Conference on Safety. : June 13-15, 2007, Tampere, Finland..
  • Konferensbidrag (övrigt vetenskapligt)abstract
    • presentation done in safety reports is to reveal risks using reliable methods and to gather informationfor rational decision making including physical planning and risk management.There are several difficulties connected to current use of risk assessment methods. One of thedifficulties is uncertainties in the probabilities estimation calculated in quantitative risk assessmentmethods. Other difficulties include unclear guidelines for the worst possible event and consequences ofan accident.Whenever a risk assessment is performed, there will be doubts about the objectivity of the results. Evenif mathematical models are building the basis for calculation, e.g. of risk frequency or scenarios used todescribe the possible consequences of an accident happening, elements of uncertainty could beidentified. These uncertainties could be used to manipulate the outcome of the assessment dependingon e.g. personal or political interests. In order to minimize the possibilities for influencing the results, astandard of how to perform a risk assessment has been established and it should be built on morequalitative and transparent principles.Another important demand on risk assessment and management today is that its results should becommunicated to different stakeholders. The communication aspect is stressed because of recognizedimportance of public participation during decision making processes.
