Buildings are the “invisible” large consumers of energy and emitters of CO2

Highly Energy Efficient Buildings ExistTechnologies exist, systems must be climate- and use-adaptive

Building Energy Efficiency: ProblemUncertainty, persistence and scalability-barriers to delivering energy efficiency

Energy performance optimization not cost effective

Performance gains/benefitsdo not persist

Information not visible and actionable for facility operator

Energy efficient design is cumbersome

Delivered performance is uncertain

Deep gains in energy efficiency require system solutions

Energy Efficient Buildings Study Recommendations

2050: Global/Local Strategic Challenge

Turkey Stats (from TBCSD):Imported energy > 70 % Average yearly energy demand increase is around 4,6% after 1990. (for EU, this increase is 1,6%) Expected energy increase is 6,7-7,5% by 2020. Energy saving potential of buildings/construction sector is more than transportation and production reaching 8million TOE.
