Urban energy vulnerability index assessment at building level

Introduction

Urban energy vulnerability index assessment at building level

Energy vulnerability is a subjective combination of risk factors

in homes that can lead to energy poverty:

• Technological: Typology of the HVAC systems, domestic appliances, and their usage 
• Social: Population and households characteristics, health conditions           
• Economical: Household prices, salary indexes, energy costs, CPI     
• Physical: Building envelope characteristics, weather conditions, air conditions

What is energy vulnerability?

/ Introduction

/ Introduction

How to assess the vulnerability of citizens?

• Through the implementation of a methodology that integrates:
  • Energy thermal building-stock modelling
  • Weather model to upscale mesoscale resolution to microlocal
  • Interdisciplinary and highly heterogeneous data sources
  • Harmonisation of the datasets in a common database framework
