Franz Fuerst Paper Energy Efficiency of Buildings: A New Challenge for Urban Models
Professor Franz Fuerst of the University of Cambridge presented his paper at the Better Building conference in 2013 on how the overall energy consumption of households is related to the location and proposed the IRPUD model for assessing the connection. This paper is an update of this research from 2015
Despite some recent conceptual studies and a modicum of empirical evidence, urban models do not currently take into account the energy efficiency of buildings. This paper presents a framework for incorporating energy efficiency and energy use of buildings into urban models based on microeconomic theory and pricing mechanisms in real estate markets. Using the example of the IRPUD urban land use, transport and environment model, it is demonstrated how a simplified model of building energy-efficient new buildings and retrofitting existing buildings can be integrated into the model to forecast the greenhouse gas emissions of residential buildings. The paper demonstrates that the long payback periods of investments in energy-efficient residential buildings require public intervention if the energy conservation and greenhouse gas emission reduction targets of governments are to be achieved.
