What is a Net Zero Building?
Why Net Zero is Important?• Buildings are the Largest Energy
Consumer in the U.S.– 40% of primary energy, 72% of electricity,
55% of natural gas
Commercial Sector Trends• Energy use increasing 1.6% per year – faster that energy efficiency

Automated Technologies will drive Net Zero Energy Buildings
Pearl River Tower(A Near Net Zero Building)in Guangzhou, China
The building is designed with energy conservation in mind, including wind turbines and solar collectors, photovoltaic cells, raised floors ventilation, and radiant heating and cooling ceilings. It will be arguably one of the most environmentally friendly buildings in the world.
Pearl River Tower’s accomplishments, many are related to the sustainable design features including:
•The largest radiant-cooled office building in the world
•Most energy efficient super-tall building in the world
•The tower is an example of China’s goal to reduce the intensity of carbon dioxide emissions per unit of GDP in 2020 by 40 to 45 percent as compared to the level of 2005.
Conclusions
•Net Zero energy buildings are more a concept than a hard target in most of the Asian countries except Japan.
•Net Zero energy buildings are usually used to demonstrate low carbon technologies.
•The major market for Net Zero energy buildings will be in Europe.
•Market adoption for Net Zero buildings worldwide will be gradual.
•Net Zero energy buildings will be composed to multiple technologies bound together by building automation
•China will be posed to dominate the manufacturing market for Net Zero subsystems, such as solar photovoltaic.
