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
Very Low Energy>50% Reduction
LEED Design20-50% Reduction

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

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.
