WHY AND HOW SUSTAINABLY DEVELOPING AND RETROFITTING
BUILDINGS IS CRITICAL TO REDUCE OVERALL ENERGY CONSUMPTION
Agenda
• Why • How • Challenges
40% of global energy is used in buildings

Carbon dioxide from buildings (GtCO2)
Policy tools are used to encourage energy reduction in buildings.
U.S. goal is 30-50% less energy consumption in new buildings above 2006 levels.
China has strong codes for large buildings only; ~50% new bldg in world.
Sweden has the most stringent energy efficiency requirements in the world.
Japan has very good labeling program but does not inspect for efficiency.
India has voluntary code for large buildings only since 2007.
#1 USA #2 Canada #3 India #4 China
Voluntary programs prove technical feasibility and prepare market for regulation.
Diffusion of Innovation
Note: this is just my observation
Sustainably developing and retrofitting buildings is critical to reduce overall
energy consumption.
But we face many challenges.
Unprecedented growth
Disasters and climate change
Market and technical challenges
due to the amount of energy that buildings consume and we reduce energy using regulation and voluntary programs against challenges of rapid urban development, disasters and climate change, and market and technical challenges.
Sustainably developing and retrofitting buildings is critical to reduce overall
energy consumption
Thank You
