    1. 1. Reducing Energy Consumption by Innovation David Parekh Vice President, Research and Director United Technologies Research Center This document contains no technical data subject to the EAR or the ITAR.
    2. 2. Energy Challenge Buildings are the “invisible” large consumers of energy and emitters of CO2 Source: IEA “Worldwide Trends in Energy Use and Efficiency”, (2008)
    3. 3. Highly Energy Efficient Buildings Exist Technologies exist, systems must be climate- and use-adaptive Energy Retrofit 10-30% Reduction Cityfront Sheraton Chicago IL 1.2M ft2, 300 kW hr/m2 5753 HDD, 3391 CDD VS chiller, VFD fans, VFD pumps Condensing boilers & DHW LEED Design 20-50% Reduction Tulane Lavin Bernie New Orleans LA 150K ft2, 150 kW hr/m2 1513 HDD, 6910 CDD Porous radiant ceiling, humidity control, zoning, efficient lighting, shading Deutsche Post Bonn Germany 1M ft2, 75 kW hr/m2 6331 HDD, 1820 CDD No fans or ducts, slab cooling, façade preheat, night cool Very Low Energy >50% Reduction
    4. 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. 5. Value of Integration Technology Stakeholder Value Early total solution trade-offs Plan Optimal building as system Design Reduce cost and schedule Build Reduce cost and improve functionality Safety and security Operate Building Lifecycle Technology Enables Turnkey solutions Thermal integration Design-to-service Energy savings Comfort Auto-commission and setup Real time monitoring, control, and diagnostics
    6. 6. Energy Efficient Buildings Study Recommendations 6
    7. 7. 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.
