I am examining several options for Horizontal shading for an office building using EQUEST.
A synopsis of the answers is as follows:
Total Annual Energy MBTU Space Cooling MBTU Space Heating MBTU Unshaded Option 8380 2411.9 308.1 2.5 ft Horizontal shading on East West and South
7936.8 2178.8 284.2 5 ft Horizontal shading on East West and South
7835
2158
269.7
The Questions:
1. Its very baffling to see the heating consumption go down too. I wanted to see an increase in heating on implementing the shading devices. How can I justify that decrease?
2. The building has a total area of 210273 sqft. with 15 ft deep perimeter zones. The shading reduces the energy consumption by 5 to 6 %. Is that acceptable?
Any help is greatly appreciated.
Thank you
