IES and Armstrong® World Industries have collaborated to enable simulation of Templok® PCM in IESVE

IESVE 2025

Image description Image description Image description

For the first time, it is now possible to model the effect of Phase Change Materials (PCMs) within IESVE. The integration of Armstrong® Templok Ceilings® into the VE provides a pre-packaged, fast, and easy-to-use method of inputting and accurately evaluating the impact of Templok energy saving ceiling tiles on building energy use, carbon emissions, operational costs, thermal comfort, and more.  

  • Armstrong and IES partnered to develop a thermodynamic model of Templok Phase Change Material (PCM), validated with laboratory data.
  • IESVE integrates Templok within its construction database, with pre-packaged and validated performance data, enabling users to quickly add the product as a distinct construction without the need to source and input manually.
  • Appropriate modelling of HVAC strategy is key to the success of PCM integration. IESVE provides an associated “Armstong” set of preconfigured HVAC system control strategies to ensure the PCM is working to its full potential and modelled holistically.
  • Additional simulation outputs are provided to enable inspection of PCM performance, including Temperature, Specific Heat and the State of the material (Liquid Fraction) at each timestep.
  • The Armstrong® Templok Ceilings® tile has also been made available to the following tools with IESVE
    • Parametric tool so that users can explore the impact of PCM integration across a wide range of model parameters.
    • Plenum/void/stratification tools so users can automatically create and assign PCM to applicable room configurations easily.

COMPLIANCE

IESVE Approved for Compliance with Gibraltar Part F (2007) using Dynamic Simulation Modelling

IESVE 2025

IESVE already delivers the most comprehensive set of global building energy regulation, code and rating system compliance solutions within any dynamic simulation modelling tool. With the addition of Gibraltar, IES bolsters its coverage, reducing the number of tools users need to invest in, whilst saving significant modelling time.

  • Within Gibraltar IESVE delivers an alternative dynamic simulation route to Part F compliance for Compliance document and EPC generation that allows designers in the region to model and show compliance on buildings where sophisticated architecture, layouts, systems, controls, or renewable generation are utilised.
  • Such approaches are needed to achieve low carbon building design in Gibraltar’s Mediterranean climate, which is one of Europe’s most space-constrained and air conditioning reliant nations.
  • IESVE allows for automated compliance calculations and quicker assessments, which help both the Gibraltar government and industry professionals manage the complexity of building energy regulations effectively.
  • IES is the only software company to work directly with national and local governments, including Gibraltar, on energy compliance solutions for buildings.
Additional Enhancements

Additional Enhancements

IES has an ongoing commitment to improving and investing in its software with the goal of enabling energy modellers to make informed design decisions. IESVE 2025 responds to key customer feedback with updates to the VE Python API, a tool that empowers users by automating the process of harvesting input and reporting data direct from the VE and enabling bespoke post processing and report creation. In addition, modellers can benefit from improved software performance during the geometry modelling process through fundamental changes to the ModelIT framework within IESVE 2025.

  • Within ModelIT the performance of important functions (such as undo, storey creator, rotate object) have been optimised. This saves users valuable time when undertaking model creation and design iteration processes, which can be some of the most time consuming aspects of analysis.
  • The VE Python API has been updated to Python version 3.12.3 (2024) delivering a wider range of script content and features, and access to new 3rd party modules and libraries, via the built-in VE Script Python Editor. This unlocks up to date script tools and better presentation of outputs and reports. 
  • VE Python API capabilities have been extended in recent years to allow access to detailed model data and in particular the full range of ApacheHVAC system information. Further updates now allow for Thermal Comfort metrics to be extracted from simulation results.
  • Users not familiar with Python Scripting, can still access the capabilities via the VE Navigator sample scripts, or free downloadable scripts within the Content Store. IESVE 2025 updates are in part due to collaboration between the IESVE API development team and 3rd party script writers, enabling IES to deliver tools that are a perfect fit for modellers in the industry.
