The following clip is adapted from the recent announcement released last week by NBI on the results of achieving zero state update and zero energy consumption building list in 2018.
Even in areas with high energy density, building types are expanding: zero energy buildings can be found in more and more building types.
As in the past few years, the comprehensive education market, including K-12 schools, higher education and general education, dominates the whole education market, reaching zero in 2018, accounting for 37% of buildings.
So far, California is the leader in zero energy construction activities, and Oregon has the second largest number.
Zexinxing building is a mixture of measuring and estimating energy use.
The Rocky Mountain Institute (RMI) and the New Building Institute (NBI) jointly hosted the 2018 National Forum on achieving zero building in Pittsburgh from April 17 to 18.
Home builders said the Ze housing project “is profitable, sustainable and rewarding for their businesses and customers.” More and more communities and business districts have opened up a key path to expand zero energy buildings.
The northeast and southwest regions have the highest growth rates, with construction increasing by more than 90% since 2014.

Private sector investment and the emergence of zero energy consumption in regions are increasingly favored by the private sector.
As the design team gains capacity, the scale of emerging projects continues to expand.
The total average energy index of its site is 24 kilobits per square foot per year.
In the whole list, nearly 26% represent for-profit and private sector buildings, and the total private ownership rate is currently 46%.
If you have passive houses or zero carbon buildings, you can come to zero Hao to discuss cooperation: Zero Hao green construction technology brings you zero carbon buildings, healthy and energy-saving buildings, energy-saving transformation of existing buildings, constant temperature, humidity and oxygen comfortable buildings, passive low-energy buildings, design, supply, construction, operation Certification of a number of green building services welcome to join the cooperation platform carbon neutral building leader Tel: 13636456523 wechat QR code..
In the emerging list in 2018, more than 40% of the buildings and 88% of the total construction area are 50000 square feet or more.
There are several trends in the report: zero energy buildings are growing in more and more climate areas.
Most of the certified zero energy buildings (about 80%) are less than 25000 square feet, reflecting the early trend of small demonstration buildings becoming zero.
According to NBI’s latest certification and list of emerging zero energy buildings, zero energy buildings have developed well in the past two years.
The forum is a leading industry event aimed at expanding the market for zero energy buildings and communities.
The median total site energy intensity (EUI) of Ze certified buildings is only 18 kilobits per square foot per year (before renewable energy).
This year, the list includes nearly 500 verified and emerging Ze buildings in the United States and Canada – a significant increase of 700% since NBI began tracking projects in 2012, and private sector investment now accounts for nearly half of all buildings on the list.
These 482 buildings represent more than 45 million square feet of commercial space, including 67 proven projects (with at least one year of energy use and production data to prove the performance of Ze) and 415 emerging buildings (the stated goal is zero energy, but it has not been completed, fully occupied or still striving to achieve the performance of Ze).
However, the list of Ze emerging buildings in 2018 shows that the distribution of building scale is more uniform, which indicates that large Ze buildings are entering the market, and more buildings of different sizes pursue zero energy consumption.
According to one of the most stringent basic codes in the United States (catitle24), buildings on the Ze certified list use an average of 60% less energy than existing comparable commercial buildings in the United States and 46% less energy than new buildings.
The first book to contribute today is the guide to zero carbon building standards.
Zero energy buildings surpass the climate of North America and border on buildings in 44 states of the United States and 4 provinces of Canada.
California’s leading energy policies, ambitious energy conservation goals and effective utility plans, as well as Oregon’s net zero efficiency plan and incentives, are promoting their rapid application in Ze buildings.
Even high energy density building types, such as hospitals and restaurants, are looking for innovative ways to pursue zero energy consumption.
Certified buildings consume less than half of the energy of typical buildings.
This biennial list lists projects in North America, but more importantly, it reveals key market trends that mark the overall health and momentum of the Ze market.
We are an enterprise focusing on passive houses and zero carbon buildings.
