max + min daily temp (C) with and without ivy
average temp + humidity range between ivy-covered and exposed surfaces
green wall benefits:
- can reduce ambient surround temperatures by 2 degrees (c) on average
- can reduce the U-value of a lightweight wall from 1.24 to 0.69 (W/m2) and heavyweight from 1.16 to 0.68 (W/m2)
- can reduce heat gain by up to 75%, and there-by also reduce cooling loads by 75%
