2. Project Background APEC Program-- Nearly (Net) Zero Energy Building
Between 1971 and 2010, total energy consumption in the buildings sector grew 1.8% a year, from 58 EJ to 114 EJ. The residential sub-sector requires the largest share of energy (around 75% of total energy consumption in buildings), although the services sub-sector has increased in share of total buildings energy use since 1990, from 23% to 26%

3. APEC Program-- Nearly (Net) Zero Energy Building
Project Background
（1）Policy: the federal government enacted the Executive Order 13514
As of 2020, all planning for new Federal buildings requires design specifications that achieve Zero-Net-Energy use by 2030.
Large government buildings have to start showing progress by 2015.

APEC- EWG – EGEEC XC
11-12 April 2013 North Star Continental Grand Hotel
Beijing, China
With the support from China national energy administration, we participate the 41st APEC EGEEC meeting at Beijing and have an opportunity to share information and discussed with the experts in this group that how could the information and experience sharing of NZEB could benefit the APEC region.
How to share the existing experiences and best practices of NZEB to promote it among APEC region is the main focuses of this proposal which will benefit both the new building construct work and existing building retrofit work in both developed and developing economies.

8. APEC Program-- Nearly (Net) Zero Energy Building
APEC-Net Zero Energy Building workshop (Oct 2013 Beijing. China)
Two workshops are prepared on the topic of NZEB, first one is focus on policies and definitions, research programs and latest technology progress and how building codes upgrading influence the work of NZEB, Which held on Oct in Beijing, CABR. Fifty-two delegates from 12 economies under the Asia-Pacific Economic Cooperation (APEC) participated the workshop.
Two billion m2 of building space have been constructed each year during the past several years, which represents as high as 50% of global construction and the construction will keep on going for the next 20 years at least, so it is crucial for the buildings in China to be designed and operated towards net zero energy. We are very glad to invite so many experts from APEC economies to share their best practices in this topic,

Pilot Buildings –USA- National Renewable Energy Laboratory
The Research Support Facility (RSF) is the laboratory's newest sustainable green building. This 360,000 ft2 Leadership occupied by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) employees, uses 50% less energy than if it were built to current commercial code and achieves the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED®) Platinum rating.
With 19% of the primary energy in the U.S. consumed by commercial buildings, the RSF is changing the way commercial office buildings are designed and built.

It was built as a ZCGH demonstration housing building in early 2013 within KICT (Korea Institute of Civil Engineering and Building Technology), which is located in the northern suburbs of Seoul, with the aim to reduce heating energy by more than 80% and electricity energy by more than 85%.
The ZCGH building has an increased construction cost of less than 20% compared with conventional residential buildings and its payback period is expected to be around 10 years.

24. Program Conclusion: APEC Program--Nearly (Net) Zero Energy Building
(1) Policy and Objective

25. Program Conclusion: APEC Program--Nearly (Net) Zero Energy Building
（2）Definition
The zero energy definition determines how to design and operate buildings to achieve the zero energy targets. It is also related to the government policies and incentives. Potentially, some definitions with similar content among APEC economies need to harmonize in the future.

26. Program Conclusion: APEC Program--Nearly (Net) Zero Energy Building
(3) Building codes and standards
Building codes and standards are the most fundamental and effective measures to promote NZEB development. Energy codes and standards play a vital role by setting minimum requirements for energy-efficient design and construction. Since 1970s to now, the building energy codes already make 50%-70% energy savings and still have a 70%-90% energy saving potential in the future. ASHRAE 90.1 and Title 24 of California in the United States have already set up goals to move to NZE step by step till 2020 and 2030.

27. Goal by institutes, societies and alliances
APEC Program--Nearly (Net) Zero Energy Building
Program Conclusion:
(4) NGOs
Major institutes, societies and alliances have all established NZE or similar targets, most of them are more stringent than the federal (national) goal

Goal by institutes, societies and alliances
Canada
SNEBRN：facilitate widespread adoption of NZEB in Canada by 2030

The United States
AIA: carbon neutral buildings by 2030; ASHRAE: Vision net zero energy usage for all types of facilities by 2020

28. Program Conclusion: APEC Program--Nearly (Net) Zero Energy Building
(5) Obstacle &Barriers.
Long term NZEB target together with a clear near objective is needed in some economies.
Significant funding is still needed for the technology research and building codes upgrading to support NZEBs become widespread by 2030.
Incremental cost needs to be balanced from the government subsidy in the near future and from technology promotion, industry growth and marketization in the long term view.
Best practice projects needs more attention to show the direct energy reduction result and verify the latest research achievements, which is the most effective way to call the interest of officers and experts to expand the project influence.
