This paper presents some of the latest resutls of an ongoing experiment quantifying, under controlled conditions, the effects of vines on wall surface temperature. The overall purpose of this study is to measure the effect of vine shading on walsl and to evaluate the interrelationship between those shading effects and differences in wal color. In our experiment, we measure surface temperature of exposed and vine covered wall panels. Since vining plants vary considerably in form and growth habit, we have tested several different plant varieties. In this latest test phase, we have increased the thickness of the test plants (from 4-6 inches to 12-14 inches), added new plant varieties, and added an additional four west facing test modules to the existing five south facing ones. Analysis of new data shows that vines can be very effective in reducing heat gain on west exposures and that increasing vine density increased the effectiveness of vines in reducing daytime wall tmeperatures.
