Urban Efficiency II: Seven Innovative City Programmes for Existing Building Energy Efficiency builds on research in the successful predecessor “Urban Efficiency” Report and captures seven new detailed city case studies from C40 member cities. It is primarily targeted at city-level policy makers and decision makers across the world. The report increases the resource and evidence base available to support cities understanding of the characteristics and impact of innovative city programmes emerging across C40 cities, that advance operational energy efficiency and retrofitting in existing, privately owned buildings.

London's Business Energy Challenge – Abstract

This voluntary programme taps into the competitive disposition of private sector enterprises to drive reductions in energy use and CO2 emissions in key London businesses. By rewarding outstanding achievements through Mayoral recognition and a diverse array of awards, London’s Business Energy Challenge (BEC) aims to foster low-carbon business practices and building usage across a large range of industry types. Overall results from the programme are analysed to draw out key carbon intensity and energy consumption performance trends for each industry sector. Data will be used by the Greater London Authority to increase understanding of the energy intensity and carbon emissions of the local building stock. Feedback is also provided to businesses in the form of individual report cards on the carbon intensity performance of their buildings compared to peers.
