4 Energy Efficient Buildings The Potential

5 Energy Efficient Buildings The Challange Energy Consumption in Office Buildings in the U.S. Source: DOE Commercial Buildings Energy Consumption Survey (CBECS) 2003 Energy Efficiency Requirements in Germany Source: DENA Deutsche Energie Agentur Energy Bill Title IV Energy Savings in Buildings Zero-Net-Energy Commercial Buildings Iniciative with the goal to develop and disseminate technologies, practices, and policies for the development and establishment of zero net energy commercial buildings for (1) any commercial building newly constructed in the United States by 2030; (2) 50 percent of the commercial building stock of the United States by 2040; and (3) all commercial buildings in the United States by 2050.

6 Energy Efficient Buildings The Reality Energy Performance of LEED-NC Buildings (NBI, March 2008) Measured Energy Use Intensity (EUI) for 121 LEED-NC Buildings compared to CBECS data

7 Energy Efficient Buildings The Future

8 Energy Efficient Buildings Integrated Project Delivery Architecture & MEP Design Innovative Design Solutions Integrated Building Design Comprehensive Understanding of Building and Systems Simulation and Modeling Energy, Comfort, Daylight, Airflow Commissioning Functionality, Performance, Documentation Monitoring & Operation Diagnostics Comfort, Savings, Persistence Energy Audit Improvement of Existing Buildings

9 Energy Efficient Buildings Integrated Project Delivery It s all about Information! Information Break Break maximum information gain Information Deficit = Performance Deficit actual information retained Break Time Design Construction Post-Occupancy Retrofit Component orientated view Functionality orientated view

10 Energy Efficient Buildings Examples Low-Energy Building with simple Technology and highest Comfort Î Details matter!

11 Energy Efficient Buildings Examples Daylighting Details matter! Without Window to Atrium With Window to Atrium

12 Energy Efficient Buildings Examples Modular Room Concept Sustainable solutions require flexibility and variability! Room Module Slab Heating and Cooling Mechanical Ventilation Electrical Installation Facade and Shading System

13 Energy Efficient Buildings Examples Energy Performance and Monitoring Energy Efficiency is an ongoing effort!

14 Energy Efficient Buildings From Design to Operation Elements of Green Building Certification Verification vs. Evaluation M&V Energy Modeling Commissioning Information possible scope of information Information Deficit = Performance Deficit Break Break actual scope of information Break Time Design Construction Occupancy Change of Utilization
