Life-cycle environmental and economic assessment of nearly zero-energy buildings: a case study in Norway

Roberta Moschetti

Norwegian University of Science and Technology

Roberta Moschetti is a building engineer and currently a postdoctoral researcher at the Norwegian University of Science and Technology (NTNU) at the Energy and Process Engineering Department.She received a PhD in Energy and Nuclear Science of Technology from Politecnico di Milano in 2015, defending a thesis named ‘Building sustainability assessment and rating: an Italian objective system proposal’. The thesis regarded the development of a new sustainability assessment and rating system for Italian residential buildings.Her postdoctoral project is under a cross-disciplinary research area named ‘Environmental and sustainability analyses and sustainable business models’. It concerns the analysis of projects of building energy renovation and zero-energy building construction, with the objective of performing sustainability assessments and integrating the results in the business model of such projects.Her research areas include e.g.: the evaluation of buildings’ energy use through dynamic simulations; the assessment of buildings’ environmental impacts by means of the life cycle assessment (LCA) methodology; the computation of buildings’ life cycle costs (LCC) through the Life Cycle Costing methodology; and the assessment of buildings’ indoor environmental quality through indoor air quality and thermal comfort evaluations.

Helge Brattebø is Professor of Industrial Ecology at the Norwegian University of Science and Technology (NTNU) and Director of the strategic interdisciplinary program NTNU Sustainability. He has over 25 years university experience and his research is mostly related to industrial ecology modeling of urban built environment, using methods such as dynamic MFA, LCA, LCC and scenario analysis. He has published ca 70 international journal paper, and supervised ca 60 MSc students and 20 PhD students towards their final theses.


Buildings are responsible for several environmental impacts, e.g., high energy use and greenhouse gas emissions, during the whole life cycle. The reduction of such negative impacts can nowadays be boosted through the adoption... [ view full abstract ]
