This document discusses energy efficiency in buildings globally. It notes that buildings account for 35% of global energy use, with consumption varying greatly between regions. There is significant potential for energy savings in buildings through approaches like building codes and standards, energy labeling programs, and clean development mechanisms. However, barriers like high upfront costs, lack of awareness, and weak policies still limit energy efficiency. The document outlines various international initiatives and projects aimed at promoting building energy efficiency.

4. EE in Buildings
• Construction sector – 5-15%
of GDP;
• 35% of global energy use;
• Per capita consumption
– North America -35-40
GJ/person/year;

GJ/person/year
– Developing countries – 4-10
GJ/person/year
• Considerable policy attention
on EE in Buildings

14. Summary
• Significant potential for EE gains in Buildings;
• Several barriers – financial, risk, policy,
awareness;
• Effective approches- building codes &
standards, S&L, CDM/JI, rating systems,
awareness and capacity building;
• SBCI, CLASP REEEP and others active;
• Significant opportunity but challenges
