Topic 3: Analysis of building retrofit investment risks using life cycle approach.Research Aims:Retrofitting is carried out to reduce the energy consumption and greenhouse gas emission of a building. Retrofitting of a building requires large investments and a proper risk analysis is required for decision making. Risks in a building retrofit project may come from uncertainties in installation and performance of the retrofit, maintenance, utility cost, discount rate etc. The aim of this research is to conduct a risk analysis of a building retrofit project following life cycle approach, from investor perspective and focus on investment risks.
