New technology partnership with IES

As part of our ongoing commitment to provide the best technical support to our customers and to ease the specification process we have partnered with IES (Integrated Environmental Solutions) to make a number of our products available to model within their virtual environment platform IESVE

Used by sustainable design consultants worldwide to improve a building’s performance, the IESVE platform is an in-depth suite of integrated analysis tools for the design and retrofit of buildings. It embeds energy and performance analysis into the design process across the entire building lifecycle.

Effective ventilation strategies can be complex so the fully integrated nature of IESVE offers specifiers invaluable data, ensuring natural ventilation solutions, like those which we provide, will work efficiently in operation.

Passivent Airscoop® Roof Ventilation Terminal

The Airscoop is one of our most commonly specified natural ventilation products and from Spring 2024 became available to model as part of the latest IESVE Feature Pack 5 – an integrated suite for accurate whole building performance simulation.

The inclusion of the Airscoop provides specifiers with a fast, streamlined and easy-to-use method of simulating the effect of these products within Virtual Environment models.

The Airscoop roof-mounted terminals provide displacement ventilation to large buildings and deep plan spaces. Designed to ‘capture’ prevailing wind and direct it via four separate chambers within the terminal to the space beneath, the optimised segmented design delivers maximum airflow capacity with minimal pressure drop through the system.

Dedicated VE Navigator

A dedicated VE Navigator has been created to guide users through a stepped process, from importing the Airscoop into the model, configuring the operation, preparing, and applying to rooms, thermal simulation and compliance analysis.

More to come

The agreement with IES will see more of Passivent’s products become available during 2024.
