This is a
collaborative research project between U.S. and Japan, a pending project
proposed to NSF and JSPS Grant-in-Aid program, to help understand the
mechanism of interaction between environments inside and outside of the
greenhouse, structure, and environmental control methods under semiarid
climate in Southwestern US and to develop an effective environmental
control algorithm that can create conditions suitable for plant growth as
well as minimize the water and energy usage. The results are
expected to contribute to developing technologies for efficient food
production not only in the Southwestern US, but also in semiarid areas
worldwide including Mexico, China, and Middle Eastern countries, where
food security and sustainable production are critical issues.
Initially, work will focus on: natural ventilation measurement with
a tracer gas SF6 using instrumentation; analysis of air current speed
profile inside greenhouse; and measuring the diurnal change in solar
radiation light quality inside greenhouse.
