Feature Pack 2 Updates

Geometry & BIM Enhancements

  • Ability to configure/divide a room surface into smaller surfaces. E.g. for “Spatial Mean Radiant Temperature” calculations used in Occupant Thermal Comfort calculations.  Surfaces can also be healed/consolidated from BIM imports.
  • New BIM toolbar in ModelIT containing tools to fix problematic imported BIM models natively in ModelIT.
  • ModelIT Copy and Paste which copies model opening geometry and data from space to space. 
  • Intelligent Snapping upgrade:  Easier and more intuitive snapping of mouse point to any snap points within the snap tolerance.
  • Auto-Map gbXML Templates to any useful IESVE/Apache Templates, save & re-use.
Spatial MRT
International Glazing Database

Import from International Glazing Database

  • Interface in APACHE that imports glazing materials from the International Glazing Database (IGDB)  
  • Online database is hosted and maintained by Lawrence Berkeley National Laboratory (https://windows.lbl.gov/software/igdb) 
  • Imported materials are readable by APACHE for load calculation and energy/carbon simulation
  • Imported materials are readable by RadianceIES for daylight simulation (e.g. sDA) and glare prediction (e.g. DGP). 
     

RadianceIES Enhancements

  • Spatial Daylighting Autonomy (sDA) speed improvement – up to 6X faster
  • Perez Sky option added for IES LM 83 simulation (sDA and ASE)
  • 15,000 lux CIE Sky added to sky types

Multiple Cooling Towers or fluid coolers per Condenser Water Loop

Condenser Water Temperature Control

Condenser Water Temperature Control: Approach

  • Two new Condenser Water (CW) loop Supply temperature setpoint options that include Approach as a control variable.
    • “Reset per fixed approach to outdoor WBT”: The CW loop supply temperature will be based on the user-specified approach temperature.    
    • “Reset per outdoor WBT range and fixed approach”: In this option, the CW loop supply temperature will have three setpoints based on the outdoor Wet-Bulb Temperature (WBT). The three setpoints are shown in the plot and are highlighted in the CWL dialog along with other available user-specified values.

Fan & Pump Enhancements

Alternative methods to determine pump & fan power has also been introduced which gives users the ability to specify:

  • Fan brake horsepower at design conditions instead of fan efficiency and static pressure. 
  • Pump head, design flow, impeller, and motor efficiency as an alternative to simply entering Specific Pump Power or “Power-Per-Unit-Flow” (W/gpm or W/l/s).
