the benefits of smart grid technology for buildings, cities, and sustainability
DESCRIPTION
June 15, 2011 Audrey Zibelman's presentation from America’s Sustainable Future: How U.S. Cities Are Making Energy Work, an invitational conference of public-private partnership efforts from U.S. cities pursuing innovative energy management and smart grid initiatives. The assembled leaders in industry, research and policy-making will explore the diverse energy strategies emerging in Philadelphia and across the United States. “We’re really looking forward to both learning from the great examples set by other cities represented in the conference, and showing off the groundbreaking work happening right here in Philadelphia,” says Laurie Actman, Viridity Energy’s director of strategic partnerships and public policy. “With smart ideas and smart policy, we should be able to build support for smart grid projects and microgrids at the federal, state and local level.”"Energy technology is changing at such a rapid pace, it's crucial to examine who's doing it right in smart grid and microgrid projects all around the country," says Eugenie Birch, Penn IUR co-director. "With the right policy moves—which we'll be exploring at the conference—Philadelphia can be a national leader in energy innovation," noted Susan Wachter, Penn IUR co-director.TRANSCRIPT
The benefits of smart grid technology for buildings, Cities and sustainability

Where We Are Today?
• Viridity founded to give new info and technology to consumers
• March 2011 FERC ruling: a MW generated is financially equivalent to a MW conserved NEGAWATT = MEGAWATT
• Consumer-led demand reductions lead to lower power prices—interesting politics
Just like IT and telecom, our energy network is on the cusp of a paradigm shift – led by advanced technology, networked devices, and informed consumer choice.

Leveraging a Building for Energy Savings and Revenues
Efficiency - Reduction of KW consumption per square foot over all hours
Demand Response – The ability to reduce consumption in response to a utility request
Dynamic Demand Optimization – The automated and continuous active management of building load from the power grid in reaction to real time prices while ensuring that tenant comfort, sustainability and productivity concerns are addressed.

A smart grid vision for the future
1. Pro-sumers: Universities, hospitals, skyscrapers, and corporate campuses that use new technologies and information to make smarter, cost-effective choices about their energy use.
2. MicroGrids: Sites that combine distributed generation, onsite storage, and optimized energy use to improve energy security and reduce electricity bills.
3. A Sustainable Grid: through new technology and consumer action, a transmission network that delivers power more securely, more inexpensively, and more environmentally friendly.
