IECC 2012 Navigator

A dedicated Navigator for the International Energy Conservation Code (IECC) 2012 performance path (Chapter 4).

Modelling any specific code compliance or voluntary rating system methodology correctly is a tricky undertaking for any modeller. Which version of the code to use, what are the specific requirements of this code and what are the requirements for all the various models that need creating to address the code requirements? For IECC 2021 it is no different, there’s the proposed building, the reference building and all the building and HVAC system data that makes them up. In truth it could be a bit of a minefield…

This is where the patented IES Navigators really come into their own ensuring that all the vagaries of the chosen code compliance methodology are automated and contained within an easy to follow workflow with the end point being reportage that can be used directly in your submission.

  • IESVE Software (2018-FP01) provides a performance path for the International Energy Conservation Code (IECC) 2012, to complement the existing ASHRAE 90.1 performance options available in IESVE.
  • Software users will benefit from this compliance alternative for commercial buildings in 15+ US States.
  • A dedicated IECC Navigator for the IECC performance path (Chapter 4). Automatic creation of the IECC Reference model - a time-saving feature.
  • Automatic creation of IECC compliance reports.

There is a lot of model information to handle when carrying out an IECC 2012 assessment and it would be easy to introduce errors, the Navigators assist here greatly reducing the chance of human error:

  • Structure the modeling process in a concise manner using the integral innovative workflow
  • Manage and edit data for baseline and reference buildings from one central file reducing input duplication and error
  • Use the built-in Quality Assurance to reduce errors and facilitate team collaboration
  • Model in detail complex building geometry, HVAC or Renewable Energy systems
  • HVAC Sizing reporting included for the building, plant, systems, zones and rooms.
  • Streamlined annual daylight simulation within the annual energy simulation in the same model
  • IECC HVAC libraries of HVAC data including:
    • 11 systems, most have 90.1 equivalents
    • 3 new systems – Two and four pipe fan-coils & WSHP
    • HVAC System Guidance for IECC Reference Building
  • IECC Reference template data
    • Construction performance data
    • Lighting Power Densities by IECC space types
    • IECC lighting controls
  • IECC compliance report with pass/fail criteria – building energy cost must be less than or equal to 85% of the standard reference design building
