Who is the EMerge Alliance? Architects, Engineers Contractors/Builders/ Integrators Manufacturers - Service Providers Building Owners Facility Managers National & Independent Labs Academic Institutions Codes & Standards Groups What is an EMerge Standard? Commercial Applications Standards Subordinate to safety, equipment standards Physical, electrical, operational interfaces Application definition - listing requirements of other standards (incl. IEC) 3 Vision Standards Eco-System Transformation 3

4 Net Zero Energy Building Model Buildings that produce as much energy as they consume 1. Integrated design and operations planning 2. Site renewable strategies get optimized using dc 3. Energy Storage in dc allow Grid independence 4. System Intelligence control, monitor, verify On-site Electricity Demand DC Net Zero Energy AC Distributed Renewable Energy DC power would fundamentally change the way power is distributed in commercial buildings 2012: Begin DC Microgrid Demonstrations 2030: All new commercial buildings 2040: 50% of commercial building stock 2050: All commercial buildings Greater Philadelphia Innovation Center Energy Hub 4 EMerge Alliance Corp Vision Standards Eco-System Transformation 4

5 Zero Net Energy Buildings (ZEB) DC Microgrid with Renewable & Alternate Distributed Generation Feeds Solar PV Wind Battery Storage Gen Set Fuel Cell Other Utility Meter Microgrids may include : Various AC and DC loads: fixed & plug and play loads MPPT Wind Contr. 380VDC Converter Dispatchable generation: fuel cell or bio-fuel turbine. Non-dispatchable sources: solar PV and wind turbines. Facility Power Server and Common Distribution/Collector (380VDC Nom) Bus Energy storage, such as ultracapacitors or batteries. Common Distribution Collector Bus Lighting Loads 24VDC Plug Loads 380VDC EV Charger 380VDC HVAC Loads 380VDC Electronic Loads 380/24VDC ICT Desktop 24VDC Data Center 380VDC Management & Demand Response (DR) capability Ride-thru & Off-grid operation capability (islandable) Loads Slide Courtesy of 5 Vision Standards Eco-System Transformation 5
