anyone savvy enough with HVAC and intellectually generous enough to let me see if i can drive a stake through some is the HVAC i have been reading up on? it is one of the few topics - like string theory is the other - that i have given up on understanding. but if anyone on here really knows rhere stuff i would be interested in taking another stab at it. the problem i have is a guy like ching is so hopelessly reductive i never get it. and MEEB is hopelessly technical. even standing next to a unit on a roof or a mini split system and discussing it with an HVAC comtractor makes my eyeballs bulge. anyway, i am looking at e great illustration in an oak ridge national laboratories document written it appears for architects and it makes me hopeful it might be with taking another stab at it one last time. anyone game? like enthalpy is what again? what does an evaporator do? a chiller? a boiler? a heat exhanger? a energy recovery ventilator? i’m thinking with a little “peer to peer” help i might (?) finally put this all together. THANKS

  I'm not sure whether you have already looked at the following resources;

  • Heating, Cooling, Lighting Sustainable Methods for Architects- Chapter 16
  • Architect's Studio Companion - Section 4 
  • Amber Free Videos - https://www.youtube.com/watch?v=2wZb6HgIDE0

  I know this may seem rudimentary but what has helped me is taking printouts of system diagrams and coloring the lines with red and blue.  Don't worry about actually reading MEEB, that's insane, instead scan through it but look at diagrams because I have had several questions come directly from it. 

  AREcoach . com is a great forum where you can ask more pointed questions without the fear of NCARB breathing down your neck monitoring everything.

  More general advice:

  Ask yourself "How would a 25 year old answer?" this helps me from over complicating the question in my head with 10 years of experience.

  Don't beat yourself up if you don't pass, these tests are absolutely ridiculous.

  cassandra cook. prayerful emojis and thumbs up ones too.
  i was not aware ARE coach was still around. they had some good info for 4.0 but i didn’t realize they are still at it.
  THANK YOU for the help here.
  we really should find a way to populate this forum with advice that is more on point.
  and your input certainly fills that void...

  :)

  The AREcoach forum is definitely not as active as it was with 4.0, but if you look at the page views people are still checking it out and trying to find help from others even though they are not posting as much.

  are you in facebook or perhaps we could look each other up? one thing i would like to get out of this is to stay in contact with sensible minded professionals.
  i’m not convinced i want to walk away from these without trying to give something practical back to the testing community, in addition to making some good contacts...
