Phoenix Convention Center Phoenix, Arizona Introducing the Building Energy Asset Score Building Performance Session 2: Elements of Building and Data Management Tools Andrew Burr U.S. Department of Energy August 11, 2015

Energy Exchange : Federal Sustainability for the Next Decade Overview 2 National, free software tool for assessing the structural, mechanical, and electrical energy efficiency of commercial and multifamily residential buildings* -Envelope (roof, walls, windows) -Major energy-related systems and equipment (mechanical, electrical, service hot water) -Diagnostic tool, not an energy management tool *Asset Scores generated for more than 50 million square feet of public and private- sector property (June 2015)

Energy Exchange : Federal Sustainability for the Next Decade Types of buildings 3 Asset Score assesses the following new and existing building types: -Multifamily (low/high-rise, 3+ units) -Office -Retail -Assisted living -City hall -Community center -Courthouse -Educational (including K-12 schools) -House of Worship -Library -Lodging -Medical office -Parking garage -Police station -Post office -Senior center -Warehouse (unrefrigerated) -Mixed-Use (of the above types)

Energy Exchange : Federal Sustainability for the Next Decade How it works 4 Asset Score runs a real-time, thermal dynamic energy simulation using the EnergyPlus energy modeling engine -Normalizes for building operations, occupancy and tenant behavior -Users (owner, operator, service, provider, etc.) enter building information through an web interface –General information: # of floors, footprint dimension, orientation, use type –Envelope components: Roof, exterior wall, floor types, insulation levels –Fenestration: Skylights, windows, shading –Lighting: Fixture types, # of fixtures or % of served floor area, lighting controls –Mechanical components: Cooling/heating types, controls, equipment efficiency –Service water heating: Fuel type, distribution type, equipment efficiency
