Dixon 2 Beliefs to Question and…. ….Tough Questions to Answer Climate Change Climate Change Its getting warmer Demographic Change Demographic Change Were living longer Urbanization There are more people in cities Globalization Were doing business in more places Is global warming a myth? Will environmental regulations be reduced? Is the Smart Grid the one silver bullet to solve the problem? On a personal basis, have I done everything I can? Will the cost of energy go down in the future? Does the cleanest technology make clean energy?

Thinking beyond the building……… ……..What is a Smart Building? A safe, secure, reliable building, campus, manufacturing, or production facility that efficiently and productively consumes purchased or created on-site, electricity, natural gas, renewable, other fuels, and water, in a integrated, holistically planned and day-to-day executed, environmentally friendly strategy, from its initial green field design, through construction, migration, modernization, until retirement/demolition, that provides an acceptable return-on-investment. 4 Maryland Clean Energy Summit 2013 - 10/16/2013 - R.

SIEMENS To join the Smart Grid, Smart Buildings need to be able to duplicate many of its control functions on a local scale Smart Grid functional components Note: Diagram shows major components and is not exhaustive 1) Building Automation System Wind Gas Turbines Pump hydro Thermal Fly wheels Battery Controls & monitoring : SCADA, Energy management system, DRMS, cyber security Solar PVFuel cell Lighting Heat Chillers/ boilers Electric vehicles Pumps Switch gear Inverters Sensors Trans- formers Relays Sub metering BAS 1 A new role for building automation Traditional, central generation and storage resources will remain under centralized control. But many of the new, distributed resources will be attached to building sites (e.g. rooftop solar) and will need to be integrated through the buildings Building Automation System (BAS). Building owners are unlikely to give grid managers direct access to field-level resources. The BAS will perform an important role in managing generation, storage and consumption on behalf of the building operator. Building owner control Utility or Micro-Grid Manager Control Building owners will soon expect their building automation systems to be able to talk to the grid, or at least guarantee an upgrade path. 10 Maryland Clean Energy Summit 2013 - 10/16/2013 - R.

The Best way to predict the future is to invent it. The greater for most of us is not that our aim is too high and we miss it, but we aim too low and we reach it. Opportunity is missed by most people as it is dressed in overalls and looks like work
