[Bldg-sim] Model External Shading Devices for LEED compliance

[W. Peter Anderson]

Greetings-
Hisham makes a good point, why would you want to?  But more specifically, Table G3.1 - 5 c states shading shall NOT be modeled, so there really is no debate.

  Hi,

  The baseline has to be modeled as per G3.1.5 which does not require shading devices to be modeled. Why would you want to model them in the baseline ?? This will only compromise your energy savings.

    Thanks for the fast reply. But it is possible, anyway, to model the baseline building with external shading devices, right?

    Hi,

    Appendix G allows you to claim credit for shading designs/devices. Therefore, the baseline building is not required to have shading devices/projections.

    Dear All,



    I am new to Leed compliance simulations and I would like to know how to model external shading devices in the proposed and baseline building. Appendix G, Table G3.1 – 5. Building Envelope, is clear about permanent shading devices being allowed for the proposed building. But what about the baseline building? Do you model the external shading devices in the baseline building as well?



    I´d appreciate any help on the matter.



    Regards,

    Lizzy
