[BLDG-SIM] Energy losses through outside doors

[David Yuill]

Ahmad,
 
A significant portion of energy loss through a door is air leakage.  I
am aware of a study that examined this issue for automatic doors:   "Air
Leakage Through Automatic Doors," G. K. Yuill, Rebecca Upham, and Chen
Hui, ASHRAE Transactions, V106, Pt 2, 2000.  This might be a starting
point.
 
Regards,

Subject: [BLDG-SIM] Energy losses through outside doors
 
Dear All,
 
     I have a case in which an owner of a building needs to know which
type of outside doors will be more energy efficient (i.e. which type is
more effective to reduce the load of the Air Conditioning system).
 
    He asked me about three door types: Automatic sliding doors,
rotating doors and hinged doors. 
 
   So, can anyone provide me with a method to calculate the energy
losses through each type? or is there any study that has been made for
such case?
 
Your help will be highly appreciated
 
Thanks & Best Regards
 
Ahmad Fraij
