In September 2019, 中国’s Ministry of Housing and Urban-Rural Development (MOHURD) implemented the Technical Standard for Nearly Zero Energy Buildings. This new standard defines the way Ultra-Low Energy Buildings, Nearly Net-Zero Energy Buildings, and Net-Zero Energy Buildings are classified. The standard draws on the experiences of developed countries while taking 中国’s climate characteristics, 建筑类型, 能源的使用特点, and development trends into consideration. The standards address binding targets – including indoor environmental parameters and energy efficiency indicators – and proposes corresponding technical performance indicators, 措施, 和评价方法. 简单地说, these standards will play an important role in promoting energy conservation and emissions reduction, driving the energy-saving transformation and upgrading of 中国’s building sector.

The building sector has led to 30–40% of global energy consumption, emitting up to 40% of total carbon dioxide in direct and indirect patterns. These challenges are worse in countries undergoing rapid urbanization (like 中国).

Nearly Net-Zero Energy Buildings adopt passive architectural designs and strategies to minimize heating, cooling and lighting demands. They incorporate active technologies that maximize the energy equipment and systems’ efficiency, and provide a comfortable indoor environment with minimum energy consumption by utilizing 可再生能源. Some of these passive strategies include building envelope insulation, 外遮阳设备, and high-performance windows and doors — each a fundamental way to improve a building’s energy efficiency.

Wood-frame construction is an ideal energy-efficient solution to achieve Nearly Net-Zero Energy Building’s green development targets. Following these new standards, 加拿大木业协会 中国 developed a detailed technical guide for high-performance wood construction aligning with the Nearly-Net Zero target parameters. The guide includes technical details for how to meet specific high-performance criteria performance requirements within planning and design, 程序集, 空气的障碍, 能源系统, 可再生能源, 和建模.

Jiangsu Urban and Rural Construction Vocational College was an ideal partner for the development of a Nearly Net-Zero demonstration project. College management decided to change the design to meet the requirements of Ultra Low Energy Building or Nearly Net Zero Buildings. 在CW中国的支持下, the college decided to use light wood frame construction, and to incorporate a high level of prefabrication in one of their buildings. The combination of renewable energy, 如太阳能, green building and the low carbon aspect of wood frame construction will showcase the benefits of the building from a systemic approach, and establish a new demonstration of the possibilities for wood frame construction within the Nearly Net-Zero Building standards.
