2. Energy Challenge
Buildings are the “invisible” large
consumers of energy and emitters
of CO2

3. Highly Energy Efficient Buildings Exist
Technologies exist, systems must be climate- and use-adaptive
Energy Retrofit
10-30% Reduction

4. Building Energy Efficiency: Problem
Uncertainty, persistence and scalability-barriers to delivering energy efficiency
from LBNL/DOE report
from NIBS report
 Energy efficient design is cumbersome
 Energy performance
optimization not cost effective
 Delivered performance is uncertain
 Performance gains/benefits
do not persist
 Deep gains in energy efficiency require
system solutions
 Information not visible and
actionable for facility operator

5. Value of Integration Technology

8. Energy Intensity
2050: Global/Local Strategic Challenge
Energy Use (per capita)
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.
