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.

Retrofit Chicago Energy Challenge – Abstract

The Retrofit Chicago Energy Challenge (“the Challenge”) encourages, supports and celebrates voluntary energy efficiency leadership among large commercial, institutional, and private buildings throughout the City of Chicago. In partnership with diverse public, nonprofit and private stakeholders, the Challenge motivates and guides voluntary action towards reducing energy consumption by 20% over five years. The Challenge provides direct support and peer networking to help participants achieve their energy goals. Additionally, it facilitates best practise sharing and showcasing of ambitious energy leadership and impact.
