Approved Ruling: The request to use the window to wall area ratio rather than the window to floor area ratio to establish eligibility/ determine reference building glazing (in EHC-1) in apartments where all walls are external (i.e. no intertenancy walls) is AWARDED. This is because the use of the window to floor area ratio rather than window to wall area ratio in apartments and terraces is due to the presence of intertenancy walls, which are lacking in this project due to breezeway- corridors. Please note that this type of construction performs less thermally than a similar apartment building where corridors are within an insulated and enclosed corridor, due to the presence of high amount of heat loss surface area with respect to the size of the dwelling, and are thus not encouraged. |
