[esp-r] 18 Floor Apartment Building

[Ian McCall]

Good-day!

I am new to the ESP-r world and would like a recommendation of how to accurately 
/ efficiently model the energy consumption of an 18 floor apartment building. 
 Attached are two floor plans of the 1st and 2nd floors (please note that there 
are significant inconsistencies between the two plans ie. the location of 
elevators, and stairs etc..). The 1st floor has 47 rooms which I have combined 
into 10 different zones. The 2nd floor has 39 rooms that I have combined into 11 
zones (4 apartments per floor + 1 stairwell + 2 elevator shafts + 4 loggias 
/ mezzanines). The floors numbered 3-18 have the same geometry as the 2nd 
floor. 

Specific questions:

1) I have decided to enter the geometrical data directly into ESP-r model. I 
think that this is easier then using a 3rd party program (dwg / dxf files) to 
create the floor plans and then later import the files into ESP-r. Was this the 
right choice? 

2) I have created the 5 floors of geometry and have noticed that I will quickly 
run out of zones. Can I simplify my model to 2 or 3 floors and then extrapolate 
the results for an 18 storey building? 

3) I have combined all the rooms in the apartments into one large zone and one 
small zone; hence I am assuming very well-mixed conditions / 
temperature distributions within a large air volume. Is this combination of 
rooms possible or do I need to keep the room / apartment complexity in order to 
accurately model the network flow / dynamic infiltrations? 

4) A 5 floor building with 10/11 zones per floor leads to a very visually 
complicated model in ESP-r. It is very difficult to modify zones / grometry 
etc.. due to the visual complexity. Is there a way to hide zones? 

I am sure more questions will arise as I dive further into modelling this 
building. 

Cordially, 
Ian
