off topic - HVAC design for residential

Recommended Posts

This is way off topic but I need some help. We just switched to the 2015 IECCC. My local plans examiner just told me he's going to start requiring HVAC duct designs for additions. I already use a consultant to provide HERS ratings and Manual J for new homes, but for a second story dormer addition this is getting nuts! I asked if he's going to require hot water baseboard pipe design and baseboard lengths and he said no. HOWEVER, he's going to want an analysis calculations to prove the existing how water heater and furnace can handle the additional load. 

 

I'm an architect, not an engineer. Does anyone know of software that can get me started on this because there is NOWAY I am telling me clients they need to hire an additional consultant to get a permit to add a family room, or finish a garage, etc.. This is getting completely out of hand. Tomorrow I am submitting my resume to the local 7 Eleven. Life has to get easier.

Thanks. I saw those links on the ACCA website. I'm reviewing them. Is anyone else doing these designs for their projects or is this single plans examiner being a little too anal with the code interpretation?

this where BIM could come into play

 

create the model in Chief - send the plan to the HVAC software - it does its thing to the model

then back to Chief - then off to the next app if needed

 

then finally to layout

This is becoming a problem for me too as there are three projects on the boards now that need more MEP than I can manage easily with CA.  Just received my $20 copy of SuperCool last week but it leaves a lot to be desired as a workflow solution.  I've installed a trial copy of Revit which has all the features including a steep learning curve and a high monthly cost.  

 

The lack of a third-party platform with CA is hurting.

I've talked to HVAC contractors and they don't even know how to do it, without talking to an HVAC engineer.

      Hi Guys and Girls.
       
      I've been away form this forum for a long time, maybe some of you still remember me.
      I had another job for a few year and I didn't have time to be here, how ever Covid struck and I lost the other job.
      So to make some extra money I will offer my symbols for sale and also take custom symbol orders, if you want something special I make it for you.
       
      You can see a few of my symbols, old and new on my facebook page.

      Best regards

      Here's a hvac sidewall vent similar to the Trane Bayvent. It can be used to vent many types of equipment including furnaces, water heaters, etc.

      Does Chief Architect have an HVAC ductwork tool?
       
      On commercial building plans typically show hvac trunk lines, does Chief have tool for?

      I never tried this, maybe someone else knows....how much of the original manipulation of original Sketchup items remain after they are imported into Chief?
       
      I'll try it at the office on Tuesday, just thought I would post the question here for some Sunday afteroon, below 1degree F, thniking...brrrr.
       
      Yesterday I was looking at Sketchup Pro and saw two extensions that would be tremendously helpful in lite commercial work. They have an HVAC ductwork extension and an Engineering piping extension.
       
      If you import a few symbols made in Sketchup with these extensions do you still think you can manipulate them in Cheif, or would you have to do the whole design in Sketchup and then import the finished piping layout into Chief as an end product? I hate having to switch back and forth for EVERY revision.
