[TRNSYS-users] ts15-type 56 effect of wind on heating load

[Arie Kalkman]

Hi Xavier,

The most import wind effect is the dependence of infiltration on wind 
pressure. It can be approximated using a polynomial function like a+b* 
windspeed+..
A more accurate solution is the calculation of the Cp factor of each 
surface, depending on building hight, building shape, roughness of the 
surroundings etc., and use the modified Type 56 in TRNSFLOW
The heat transfer coefficient of the outer surfaces is also dependent on 
wind speed, but for well isolated buildings this can usually be negelected.

regards, Arie.

Hi,

type 56 does not take wind  as an input,

Any method to simulate the effects of wind on the energy consumption of
the building?

thank you

Xavier D.
