New NECB Navigator for Canada

New NECB (National Energy Code of Canada for Building) Navigator. Features include:

New ASHRAE 90.1 Enhancements

  • Updated ECB (2010/2013) and PRM (2007/2010/2013) Reports
  • Zone grouping assignment
  • Automatic Receptacle controls
  • Optimal Start of HVAC Systems
  • Chilled water supply temperature reset

A New Start-Page

Upon opening VE 2018 Software, you will be welcomed with a new start page. Features include:

  • Pinned Weather data, of your most common location settings
  • New Project creation: Prototype model import options, including ASHRAE 209 prototype models
  • Dynamic information of new events and online content (new scripts, reports, etc.)

Both new and experienced users will use the new start page as a launching point into their IESVE model.

Simulation Speed Enhancements

Simulations are now ~10 times faster by utilizing the new parallel simulation mode feature. Simulations can be divided by:

  • Number of cores available
  • Number of months (user choice)

Once the divided simulations are complete, they are automatically joined back together into one simulation result set.

Note: This feature is keyed separately. Please contact sales@iesve.com

New VRF (Variable Refrigerant Flow) Capabilities

Detailed VRF capabilities in ApacheHVAC.

  • Air source VRF with heat recovery
  • Water source VRF with heat recovery
  • Fully integrated with detailed HVAC modeling (e.g. for ASHRAE 90.1 etc.)
  • Complete with performance curve data sets
  • Auto-sizable prototype systems available

New DHW (Domestic Hot Water) Feature

Detailed DHW capabilities in ApacheHVAC.

  • Multiple DHW loops, with/without recirculation
  • Integrated with heat recovery, storage tanks, etc.
  • DHW Demand and DHW Zones set by room-level or zone-level input

New Loads (+Energy) Calculations Enhancements

  • ASHRAE Design Weather upgraded to version 6 (2017 Handbook of Fundamentals)
  • Enhanced HVAC Inputs in Building Template Manager, linked to ApacheHVAC
  • Visualization of heating/cooling design loads results onto model viewer (previously only energy results)
  • System schedules & Setpoints enhancements
  • Ground-contact floor calculation improvements
  • Report improvements (RH values and SHR)

New Daylight Simulation Enhancements

  • Spatial Daylight Autonomy (sDA) & Annual Sunlight Exposure (ASE) graphics improvements and shown on working plane of 3D model viewer
  • Contoured working planes
  • Global processing capability to entire model for sDA and ASE
  • Rule-based daylight-sensor locations (e.g. by orientation) for daylight-harvesting

New Online Resources

  • Searchable website for Help (no PDFs)
  • Content Store for Scripts, reports, formula profiles, weather files, templates, HVAC systems, spreadsheets, etc.
  • User-group website for beta-testing & enhancement requests

Other New Features
