[Hap-users] U-Value for Concrete Wall with Green Wall

[Daniel Lim via Hap-users]

Iam modeling a 5-story retail building with punched windows and pre-cast concretewalls. The walls are covered with green wall at a distance of 0.7 meters fromthe concrete wall. The windows are not covered. Since the concrete walls arenow covered from direct sun, I need to make adjustments to the U-value of thewalls to account for the shading. The exterior shadings in HAP is notapplicable for this case since they apply only to windows as fins or canopy. The roof also has vegetated landscape which should also be accounted for in getting the U-value of the roof. Any advice or guidance on how to approach this in HAP is highly appreciated. Thanks in advance.
