<div dir="ltr">Dear Design Builder Users,<div><br></div><div>I have a few queries regarding modelling in Design Builder-</div><div><br></div><div>1. Is there by any chance an alternative to the VRF system type in a older version of Design Builder. I do not have the newer version of Design Builder and have been using an older version ie 3.2. The project that i need to model is for climate zone 3 as per ASHRAE 90.1.2010 and have selected the System type 4 ie PSZ-HP for the base case. However i want to model the design case with the actual VRF system or an alternative. Is there a way i can use an existing system and change only its COP value as per my design case?</div><div><br></div><div>2. How do i model the additional lighting load that is calculated for my design as per ASHRAE 90.1 separately or does it have to be input in the regular lighting tab. </div><div><br></div><div>3. The project has not specified the building envelope material specifications like walls, roof etc since this is a Retail Interior V4 project. So construction of the project is not new and is 100% existing. However for envelope modelling purpose i have selected the standard base case values for new construction for both the base and design case. Is this right?</div><div><br></div><div>Inputs appreciated on the above points.</div><div><br></div><div>TIA.</div><div><br></div><div>Namrata</div><div><br></div><div><div><br></div>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><font face="arial black, sans-serif" size="4"><img src="http://www.sprout-green.com/assets/logo.png"></font></div><div><font size="2" face="trebuchet ms, sans-serif">Thanks and Regards ,</font></div><div><font face="arial black, sans-serif" size="4"><br></font></div><div><font size="2" face="tahoma, sans-serif">Pranati Shroff & Namrata Dhamankar </font></div><div><font face="arial black, sans-serif" size="4"><br></font></div><div dir="ltr"><div><span style="color:rgb(68,68,68)"><font style="background-color:rgb(255,255,255)" face="times new roman, serif" size="2"><span style="color:rgb(12,52,61)"><b>a:</b></span> Sprout ,Prabaht Printing Works , </font></span></div><div><span style="color:rgb(68,68,68)"><font style="background-color:rgb(255,255,255)" face="times new roman, serif" size="2">427 Gultekdi, Ind Estate Corner, </font></span></div><div><font color="#444444" face="times new roman, serif" size="2">2nd Floor, Pune-411037</font></div><div><span style="color:rgb(68,68,68)"><font style="background-color:rgb(255,255,255)" face="times new roman, serif" size="2"><span style="color:rgb(12,52,61)"><b>m:</b></span> 9922215467</font></span></div><div><span style="color:rgb(68,68,68)"><font style="background-color:rgb(255,255,255)" face="times new roman, serif" size="2"><b><span style="color:rgb(12,52,61)">e:</span><span style="color:rgb(12,52,61)"> </span> </b><a href="mailto:info@sprout-green.com" target="_blank">info@sprout-green.com</a> <b><br></b><a href="mailto:projects@sprout-green.com" target="_blank">projects@sprout-green.com</a></font></span></div><div><font style="background-color:rgb(255,255,255)" color="#999999" face="times new roman, serif" size="2"><span style="color:rgb(68,68,68)"><b><span style="color:rgb(12,52,61)">w:</span> </b><a href="http://www.sprout-green.com" target="_blank">www.sprout-green.com</a></span><a href="http://www.sprout-green.com" target="_blank"></a></font></div></div></div></div></div></div></div></div>
