<DIV dir=ltr align=left><SPAN class=387564319-14062007><FONT face=Arial color=#0000ff size=2>I'm guessing if you have no operable windows and you have occupancy at that time, you will have a LOT of unhappy campers - regardless of climate type. You need fresh air to be productive. One option could be to maintain fan power and fresh air, but set the temperature higher (in tropical climates).</FONT></SPAN></DIV>

<P class=MsoNormal>Dear All,</P>
<P class=MsoNormal>What are the chances that reducing HVAC operating hours (i.e. starting it at 9.00am rather than 8.30am in the morning and shutting it down 30 minutes before closing hours), will affect indoor air quality and productivity in office buildings in Tropical climates.</P>
<P class=MsoNormal>Additionally, could lighting period be reduced during the working period and for how long within the same tropical conditions.</P>-- <BR>Kofoworola, O.F. <PRE>==================
