3D Load & Energy Calcs w/ Duct Design

Russ King joins us for a short podcast episode about using 3D load and energy calculations with duct design. Russ has developed the Kwik Model 3D software program with the help of his son, Connor.

Kwik Model 3D uses a video game platform to build a house out of boxes instead of a sketch. The software has evolved and been integrated into EnergyGauge to do load and energy calculations based on a house’s geometry. Kwik Model makes it easy and fun to create that geometry profile for a home, which makes building design and load calculation attractive to technicians. Software like Kwik Model may especially become popular as Generation Z steps into the workforce; we can expect the learning curve to be quite shallow for the digital generation.

The Manual J calculation uses the home’s characteristics in Kwik Model and does all of the mathematical calculations in EnergyGauge for an advanced load calculation. KwikModel then receives those calculations for each room. Then, you can draw the ductwork and use an auto-size function to get the proper duct size based on the calculations.

Energy simulations use several load calculations with advanced data to figure out what the energy usage will look like in a home with a certain set of load conditions.

Russ and Bryan also discuss:

  • Modeling quickly with Field Draw
  • How building materials impact load calculations and energy simulations
  • Energy simulations vs. load calculations
  • Upcoming events with Russ King
  • Kwik Model’s tech support
  • Using the Unity platform to develop software for many different industries
