Passivent’s full range of roof terminals now available in IES Virtual Environment

  • 22 May 2025

Passivent, a specialist in natural and hybrid ventilation solutions, has partnered with Integrated Environmental Solutions (IES) to make its full range of roof ventilation terminals available for modelling within the latest IES Virtual Environment (VE) 2024, Feature Pack 1.

This follows the launch of the Passivent/IES partnership and the inclusion of Passivent’s Airscoop® roof terminal in IESVE Feature Pack 5 last year.

The IES platform enables specifiers to simulate the performance of natural ventilation products within VE models. It can efficiently model natural ventilation strategies, configure operations, run thermal simulations and conduct compliance analysis as part of the early-stage design process. A dedicated Passivent VE navigator has also been created to guide users through a stepped process to complete the simulation and check compliance”.

Full range

The IESVE now supports the full range of Passivent roof terminals, which includes the Airscoop® roof terminal for displacement ventilation, the Airstract® and Airstract® iAT terminals for passive stack ventilation and the Hybrid Plus Airstract® – a patented system designed for ventilation provision or extraction. Also included is the Litevent Airstract, which combines a rooflight with a controllable ventilator.

Richard Quincey, Technical Director at IES, comments: “The VE provides a fast, streamlined and easy-to-use method of simulating the effects of Passivent natural ventilation roof terminals within models. It provides accurate whole-building performance simulation and integrates energy and performance analysis throughout the design process.”

Huw Poppy, Business Operations Manager for Passivent and Secretary of CIBSE’s Natural Ventilation Group (pictured below), adds: “We are delighted that our full range of roof terminals is now available in the IESVE. We have already been instrumental in supporting consultants with a more efficient and cost-effective outcome for their ventilation strategy and look forward to this continuing.”

The Airscoop, Airstract, Airstract iAT and Hybrid Plus Airstract terminals come with a 15 Year No Leak guarantee and are available in a range of designs, sizes and colours. They are manufactured in the UK at Passivent’s Pinxton factory in Nottinghamshire.
