SIEMENSBeliefs to Question and…. ….Tough Questions to Answer

Climate

Change

It’s getting warmer

Demographic

Change

We’re living longer

Urbanization

There are more people

in cities

Globalization

We’re 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?

Most energy consumption takes place in buildings… ….Smart Buildings are crucial to solving these challenges

A safe, secure, reliable, and comfortable facility that integrates and optimizes supply, demand, operational, and sustainability strategies that maximizes life-cycle value.

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.

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 building’s 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.

Together, We can invent our future, if we aim high and work hard.

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
