EEM11 Efficient cooling system 2 calculation
3.0
All
EEM13
The improved case does not reflect the capacity installed in chiller system 2.
Project teams shall avoid using Type 2 systems, by providing 0 in capacity and efficiency. Then use Type 3 where needed.

Fix to be implemented in 3.1
U-value calculations for bottom floors calculations
3.0
All
EEM06
Cooling and heating energy is not correctly calculated with high U-values.
Project teams shall keep base case U-value for bottom floor.

Zero values in thickness or steel rebar
3.0
All
MEM01, MEM02, MEM04
The EDGE calculator assumes the default improved value when either thickness or steel rebar is zero.
Project teams shall input 0.01, instead of 0.0 in either thickness or steel rebar

Materials base case assumptions for Jordan
3.0
All
MEM01, MEM02, MEM04
Base case assumptions do not consider structural considerations for seismic zones.
Project teams may discount structural components and additional reinforcements in slabs as a result of seismic considerations in the building code.

Virtual energy for “heating only” and “cooling only”
3.0
All
Energy
When selecting “heating only” in the “detailed input loads” no virtual energy is calculated.
Project teams may only use “No conditioning required” or “Both cooling and heating” in the interim.
