Julien S. Bourrelle is PhD Candidate and former member of the Board of Directors at the Norwegian University of Science and Technology (NTNU). His research focuses on energy calculation methodologies for Zero Emission Buildings (ZEBs) and the study of associated flows and boundaries. He is a regular participant to the International Energy Agency (IEA) Task 40 (/www.iea-shc.org/task40) since 2009. Julien also has been president of NTNU's doctoral organisation, a board member at the Norwegian national doctoral organisation and sat on the national research committee of the Norwegian Association of Higher Education Institutions (UHR) in 2012-2013.
Julien is an Astronautical Engineer. He previously studied and worked McGill University (Canada), The University of Western Australia (Australia), The University of Auckland (New Zealand), Technische Universität München (Germany) and the Universidad Politécnica de Madrid (Spain). He is fluent in English, French, Spanish and Norwegian.
The global community aims to reduce net greenhouse gas emissions, notably by a reduction in energy consumption in buildings. The development of Zero Emission Buildings (ZEBs) is a promising solution to the problem of greenhouse gas emissions. However, this type of building currently lacks a common definition, or even a common understanding.
Under the umbrella of The Research Centre on Zero Emission Buildings, this project aims to set up the basis for defining an energy and emission calculation methodology for zero emission buildings in Norway. The different flows of energy and the possible boundaries associated with energy calculation are being investigated with a focus on compliance rather than design. Also, the analysis tackles the environmental, economic and social implications of the different variables to be included into such calculations.
Different national ZEB calculation methodologies are surveyed in collaboration with the international community through the IEA SHC Task 40 / ECBCS Annex 52. Relevant calculation methodologies proposed by a selection of countries are investigated further. The different approaches and parameters used in these methodologies are to be adapted to the Norwegian realities and the scope of Norwegian ZEBs. Furthermore, the concepts surrounding energy flows in technologically advanced dwellings and traditional buildings are investigated in relation with the proposed methodologies.
A robust energy and emission calculation methodology will insure that incentives provided to the industry by policymakers will result in the development of buildings which truly will contribute to the long term reduction of greenhouse gas emissions urged by the scientific community.
