<DIV> <BR>I really got confused with this when I got a commnet recently saying that the "baseline case per section 9.4.1.2 were not modeled" and was asked to revised the baseline. So I ended up with no savings. This is in conflict with Table G3.1.6 that you have pointed out which says that No automatic lighting controls shall be modeled in the baseline building design. </DIV>
<DIV> </DIV>
<DIV>Does it mean that I am wrong when I applied also 10% savings to my baseline? This is where I got confused since 9.4.1.1.b also mentions occupant sensor that shall turn lighting off within 30 mins of occupant leaving the space. </DIV>

One of the options here is to have programmable (time-of-day) shutoff for interior lighting circuits, and you can infer from between Table G3.1 and G3.2 of Appendix G that baseline models are taken to feature only such timeclock controls for automatic shutoff. Further, it’s taken that the lighting scheduling being kept identical between the proposed and baseline adequately reflects the minimum requirements, so you aren’t supposed to try to explicitly model the programmable shutoff. </SPAN></P>

<DIV>
<P class=MsoNormal>Hello All,</P></DIV>
<DIV>
<P class=MsoNormal> </P></DIV>
<DIV>
<DIV>
<P class=MsoNormal>I am confused on the mandatory provision 9.4.1.1 which states that building larger than 5000 ft2 shall have automatic control device. Does it mean that mid-rise and high rise building cannot claim for credit in occupancy sensors shown in Table G3.2 because their GFA is more than 5000 ft2 and only small office can claim for this credit? I am sure I am not interpreting this section correct since from what I read, other modelers are claiming for savings for buildings with more than 5000 ft2 area for occupancy sensors even if mandatory requirements states that this is required which means baseline building will also have occupancy sensors.</P></DIV>
<DIV>

<P class=MsoNormal>Can someone correct me on this? </P></DIV>
