<DIV> </DIV>
<DIV>That is my next question. Where to base the fcu efficiency? You said Appendix G but the constant volume fans are for dx units, will it be acceptable? Should I use system 1&2 formula or system 3&4? <BR></DIV>

<P class=MsoNormal><SPAN style="FONT-FAMILY: 'sans-serif'; COLOR: #1f497d; FONT-SIZE: 11pt">To further what Shanta said: unless you have a legally binding lease agreement that lists specific efficiencies of the fan coil units that the tenants must buy (or a requirement that the tenants must purchase FCUs that match the basis of design on the contract drawings), then I believe the fan power of those FCUs must unfortunately match the Appendix G requirements. In other words, you can’t model an ECM motor tenant FCU in your proposed design unless there is some enforceable document that requires tenants to purchase them in this arrangement.</SPAN></P>

<P class=MsoNormal>Hello Jaigath,</P>
<P class=MsoNormal>My suggested answers follow your questions.</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>1. Does that mean I will be modeling only the common since it only the areas that were designed? No. You must model the whole building and site.</P>
<P class=MsoNormal>2. Do I need to also include the tenant areas? Yes, include the tenant spaces.</P>
<P class=MsoNormal>3. Since the tenant areas have FCU pipe provision, do I model it as FCU or do I have to model it as system 6 which is my baseline case? You may model the tenant spaces with FCU’s in the proposed model so long as you have an engineering drawing for a typical floor showing this; if you don’t have this I suggest that you ask for it. If that is not possible to obtain, perhaps a narrative from the engineer of record or the tenant lease would suffice, but I’m not 100% sure if it would. In my opinion, you’ll need to provide some documentation that the tenants must install the FCU’s in order to help the GBCI reviewers understand the argument why you are modeling FCU’s and not system 6. </P>

<P class=MsoNormal>I am simulating a core and shell office building with system 6 for my baseline. The design case is a two pipe fan coil units at common areas and all tenants will have chilled water pipe provision for them to tap their fan coil units. Based in CS Appendix 6 under step 1, model the HVAC system as described in the design documents. My question is:</P></DIV>
