First of all, Singapore's building authority may or may not accept
the ETTV calculation based on eQuest simulation. You can always try
to make the case. Arup has made this case at least once that I know
of.<br>
<br>
To do it in eQuest is quite simple. You simply need to disaggregate
the heat flow through the facade into (1) wall conduction (2) glass
conduction and (3) solar radiation. I think these values are
reported in the standard report (LS-C).<br>
<br>
An example can be found here:<br>

Methodology for Singapore’s Envelope Thermal Transfer Value
Calculation: Accounting for Non-Conventional Shading Strategies",

Local resource in Singapore, you can ask Clarice or Xuchao, or you
can always try Prof Chou of NUS.<br>

Hope this helps,<br>
