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?</div> <div> </div> <div>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?</div> <div> </div> <div>Any help
is greatly appreciated.</div> <div>Thank you </div> <div>Jaya Mukhopadhyay</div><p>
