Estimation of sky view factor (SVF)an empirical comparison of interpolation models

Abdolhossein ZarifianMehr; Laala Jahanshahloo; Hossein Zabihi; Bohloul Alijani

Volume 28, Issue 111 , December 2019, , Pages 97-117

https://doi.org/10.22131/sepehr.2019.37509

Abstract
  Extended Abstract Introduction Obtaining reliable environmental values in vast geographic areas is usually costly and difficult; therefore, the ability to predict unknown values or in other words, the use of better interpolation methods is very important. Interpolation methods utilize a set of different ...  Read More
