Dear Adnan, increase of wind speed influences the energy loss of a building in two ways: 1.
Higher convective heat transfer coefficient at the outside of external walls 2.
Higher infiltration rates You can simulate theses effects in TRNSYS like this: 1.
Open the wall type manager in TRNBuild and use an input for back side convective heat transfer coefficient. Correlate it with the wind
speed via equations 2.
Use TRNFlow Best __________________________________________________________________________________________________ Jakob Merk M.Sc.

Im Auftrag von adnan rasheed via TRNSYS-users Hello users, I have a building, for which i am calculating its energy loss through windows i am using TYPE 56 for the building energy simulation. I want to simulate the effect of fix wind velocity outside of the building and want to see the effect of increasing wind velocity on energy loss. I am using QCOMO output to calculate heat transfer through windows. And I am using equation
as an input of wind velocity in TYPE-56, but no change in Heat loss or heat required. Can anybody help me? Regards Adnan Rasheed |
