Zero Energy Buildings (ZEB)Buildings that produce as much energy as they use

What’s likely to change in the approach to design/build?

1. Integrated design and operations planning2. Site renewable energy strategies get maxed out3. Energy Storage technology will allow Grid independence

breakthroughs4. System Intelligence - More control, monitoring, verification of

everything

2030: All new commercial buildings

2040: 50% of commercial building stock

2050: All commercial buildings

“I’d put my money on sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that."

~Thomas Edison, 1880’s

Thomas Edison was right!

DC MICROGRIDSDC Micro-Grids enable significant energy savings and the

simple integration of advanced power generation technologies.

Many modern appliances such as laptops, LED lighting and communications equipment run on DC power (the type provided by batteries), yet we plug them in to the AC mains.

Also renewable technologies such as solar photovoltaics and wind power become more prevalent at a household level, DC Micro-Grids could be a cheaper and more efficient alternative.
