The JPFA's mission is to develop and disseminate technologically and economically sustainable plant factory systems
to address today's global challenges on food, the environment, energy, natural resources and health. We are devoted
to advancing the plant factory industry and controlled-environment agriculture in and outside Japan.
We work on about 20 R&D projects that use plant factories with artificial lighting (PFALs) and greenhouses on the
Chiba University Kashiwanoha campus. Employing state-of-the-art technology, we also engage in research projects
on such topics as artificial intelligence- and phenotyping-based smart plant factory systems for environmental control
This committee draws up specifications and guidelines for the use of LEDs and makes recommendations for
measuring light environments created by LEDs.

The committee supports PFAL operators by providing them with various indexes, definitions and productivity
measurement methods. The committee, composed of major PFAL operators and experts, defines terms and
indexes used in the industry, such as efficiency of electric energy, labor hours, cultivation area and space, and
discusses how to improve productivity of PFALs.
The JPFA has committees to foster collaborations among organizations for their activities on development and
The Research Committee on PFAL Productivity Improvement has made reports
on terminology and indexes that include ranges of estimated index numbers.
To help increase PFAL productivity, we collect data from commercial PFAL operators so that we can create a comprehensive and practical data library.
We would like you to respond to the following survey.
