Powerful Features

  • Generate accurate building, room, and system loads for building design engineering and HVAC equipment sizing using the ASHRAE Heat Balance Method
  • 3D modeling of the building provides powerful visualization for easy checking/editing geometry and accounts for heat transfer between adjacent spaces
  • Readily customizable templates speed the process of assigning relevant information—a quick and easy workflow that meets your daily needs while reducing potential for error
  • Solar shading, thermal mass, and self-shading of the building are taken into account to more accurately determine cooling loads for ‘right-sizing’ HVAC equipment
  • Standardized reports are easy to read and provide a range of useful engineering checks, including cfm/sf and sf/ton
  • Powerful analysis tools let you visualize detailed loads results and uncover opportunities for design optimization before and after defining the HVAC system

Our Solutions to Industry Feedback

DESIGN COMMUNITY FEEDBACK: HVAC loads and sizing tools lack visual feedback to enhance design team communication.

SOLUTION: IESVE incorporates HVAC zoning with 3D geometry and high-quality visualizations of inputs and outputs to make it easier for all project stakeholders to communicate complex information.

DESIGN COMMUNITY FEEDBACK: HVAC loads and sizing is very difficult for high performance systems like DOAS, UFAD, displacement, and Radiant Systems.


SOLUTION: Intelligent geometry objects link with HVAC objects to make it faster and easier to create, QA, and calculate loads and energy for all system types – including DOAS, chilled beam, IDDE, WSHP, DX, ASHP, VAV, UFAD, displacement, and radiant heating and cooling.  Our detailed HVAC system library is ever-expanding and features these and other system types.

DESIGN COMMUNITY FEEDBACK: HVAC loads and sizing reports are essential to high-level checks and QA.

SOLUTION: VE 2017 has expanded HVAC sizing and loads reports to make quick checks easier and faster.

DESIGN COMMUNITY FEEDBACK: Loads reports can be difficult to interpret beyond high-level checks.


SOLUTION: In addition to detailed loads reports, IESVE also supports detailed loads visualization to make it easier and faster to understand the results at a detailed level.

 

DESIGN COMMUNITY FEEDBACK: HVAC loads and sizing is time-consuming and requires lots of iteration to get it right.

SOLUTION: Pre-calculation checks reduce errors on the inputs reducing iterations.  And the simulation manager lets loads, energy simulation, and lighting simulations run in the background increasing productivity significantly by letting you keep working.

 

DESIGN COMMUNITY FEEDBACK: It’s challenging to coordinate appropriate inputs for room/zone versus system sizing.

SOLUTION: Providing tools that remember your settings so you can use one model with settings appropriate to each stage of design.
