1 Dean’s Cabinet April, 2008 Integrated, Integrated, Energy-Efficient Design

2 Dean’s Cabinet April 17, 2008 Integrated Building Systems Energy Efficiency in Transportation Energy Storage Energy Harvesting and Micropower (off-grid) Generation Data Center Cooling Smart Grid Dynamics. Control. Computation. Interdisciplinary. Unifying theme: Center for Energy Efficient Design

3 What are we trying to do? Why does it matter? Energy Breakdown by Sector Can we do 70% better in NEW buildings? 90% better? 50% better in RETROFITS? Can we do 70% better in NEW buildings? 90% better? 50% better in RETROFITS?

4 How is it done today, and what are the limitations of current practice? “Properly applied offtheshelf or state-of-the-shelf technologies are available to achieve low-energy buildings. However, these strategies must be applied together and properly integrated in the design, installation, and operation to realize energy savings. There is no single efficiency measure or checklist of measures to achieve low-energy buildings.” -NEED FOR INTEGRATION OF BEST-In-CLAS COMPONENTS “-There was often a lack of control software or appropriate control logic to allow the technologies to work well together. -Design teams were too optimistic about the behavior of the occupants and their acceptance of systems. -Energy savings from daylighting were substantial, but were generally less than expected. -Plug loads were often greater than design predictions. -Effective insulation values are often inflated when comparing the actual building to the asdesigned building. -PV systems experienced a range of operational performance degradations. Common degradation sources included snow, inverter faults, shading, and parasitic standby losses. “ -NEED INTEGRATED CONTROL SOFTWARE AND UNCERTAINTY ANALYSIS Each of these buildings saved energy, with energy use 25% to 70% lower than code. Although each building is a good energy performer, additional energy efficiency and on-site generation is required for these buildings to reach DOE’s ZEB goal. -NEED FOR FOR ENERGY EFFICIENT DESIGN BLUEPRINTS Faculty in CCDC
