THE EFFECT OF ROOF COLOR AND MATERIAL ON THE RATE OF TEMPERATURE CHANGE OF AN ENCLOSED STRUCTURE
The experiment conducted was focused on evaluating the effect of color and material of the roofing material on the rate of temperature change of an enclosed structure. These results can then be analyzed and a conclusion can be drawn whether the rate of temperature change is significantly different for white than black and whether the rate of temperature change is significantly different for the asphalt shingles than the aluminum siding. To test this principle several trials were run with white aluminum siding, white asphalt shingles, black aluminum siding, and black asphalt shingles. In order to run each trial, a heat lamp was turned on and directed at a house model for 5 minutes. The temperature of the air inside the house model was taken before and after the five minutes was up. The difference was calculated by subtracting the final from the initial temperature for each trial. After the data was collected for each material and color, four analysis of variance (ANOVA) tests were used to analyze the data. These statistical tests revealed that the rate of temperature change was significantly different in every test except between white and black asphalt; Black aluminum had a higher rate of temperature change than white aluminum, black aluminum had a higher rate than black asphalt, and white aluminum had a higher rate than white asphalt.
