The first shade-house microclimatic model was developed based on the energy and moisture balances of four shade-house system components - the shade cloth, inside air, canopy, and soil surface. The transport is parameterized by resistances for small-scale turbulence and by intermittent refreshment for large-scale non-local gusts. The temperature and humidity in a semi-infinite shade house are predicted when the six coupled differential equations based on the energy and moisture balances are simultaneously solved. The model includes liquid-water balances for surfaces. The model requires only weather data, and, if desired, measured shade-house characterization data. Weather data for running the model, inside temperature and humidity data for verifying the model, and energy balance and turbulence data for further development of the model processes were collected in a large commercial shade house near Pahoa, Hawaii from 10 January to 25 March 1992
