Buildings worldwide account for a surprisingly high 40% of global energy
consumption, and the resulting carbon footprint, significantly exceeding those of all
transportation combined. Large and attractive opportunities exist to reduce
buildings’ energy use at lower costs and higher returns than other sectors. These
reductions are fundamental to support achieving the International Energy Agency’s
(IEA) target of a 77% reduction in the planet’s carbon footprint against the 2050
baseline to reach stabilized CO2 levels called for by the Intergovernmental Panel on
Climate Change (IPCC).
At the same time, substantial investments will be required to achieve this target. These will require the combination of actions called for in this report, including building energy codes, investment subsidies, labeling and reporting mechanisms, increased and trained workforce capacity, and evolving energy-efficiency designs and technologies. All are intended to raise energy awareness globally and influence consumer and investor behavior and choice.
These conclusions and its actionable roadmap come from the Energy Efficiency in Buildings (EEB) study performed with the World Business Council for Sustainable Development (WBCSD) and sponsored by 14 multinational companies at a total cost of US$ 15 million over four years. The study’s recommendations are based on a unique data inventory of the building stock in six of the world’s largest economic regions (Brazil, China, EU, India, Japan and USA) accounting together for 70% of the world’s GDP, and divided between residential and commercial and existing and new building types. Financially driven behaviors against energy-efficiency technologies were modeled to show costs and savings under multiple scenarios. This degree of data and sophistication has never been achieved before.
