Webb28 okt. 2024 · Calibrated models were applied to validation datasets. Statistical analysis revealed that prediction efficiencies of soil reflectance models were highly quantitative. Coefficients of determination (R2) were near 1 (≥0.90) and ratios of predicted values to the measured standard deviation (RPD) were >2, indicative of good predictive models. WebbThe SRI provides an alternative to meeting solar reflectance and thermal emittance requirements for cool roofs. SRI values are set to a normalized scale that incorporates the effects of both reflectance and thermal emittance. Generally the higher the SRI, the better the roofing material’s ability to reduce heat transfer into the building. ヴォルテール 伝説

WebbA difference in contrasting light reflectance values of 30 points or more is considered as being good. However, a difference of 20 points or more may also be considered as acceptable – especially where the lighting is greater than 200 lux, or for large areas. Values of less than 20 are considered as being poor.
