METr by Phius: Introducing the Future of Energy Modeling
The METr launch blog provides an overview of the new energy modeling design tool for Phius projects.
The METr launch blog provides an overview of the new energy modeling design tool for Phius projects.
METr (Modeled Energy Transfer) is a new cloud-based modeling tool developed by C3RRO and Phius optimized for passive building energy modeling. With the familiar mechanics and interface of WUFI Passive, METr features a streamlined user experience and easy-to-use tools.
Access to METr is available through C3RRO's website. The METr subscription is available for €588 (~$610 USD). Use the coupon code betasale through the end of February for 50% off the first year of the subscription! A 10% coupon code will be available in March and will remain active through the remainder of 2025.
Discounts are also available for those with active WUFI licenses, and are determined by the remaining time left in the license term.
Project teams are free to begin using METr for certification purposes as of January 14, 2025. WUFI Passive will still be accepted for projects pursuing certification until the release of the Phius 2027 standards.
As a cloud-based tool, METr offers the option to save and store projects in the cloud which can then be accessed by any device (including Macs, and even a smartphone)! Users can also download the .json file locally to share with additional team members and/or Phius for certification. Read on for more highlights of METr.
While many features of METr are similar to those of WUFI, the first iteration of METr offers significant advantages.
Project geometry can be imported either through a .json file exported through WUFI, or a SketchUp (.wps) file. The Sketchup import time is significantly faster, allowing users to quickly re-import when geometry revisions are necessary. The interface of the geometry viewer has also been updated to more closely align with modern 3D modeling software, giving users the ability to navigate the geometry window using their mouse to pan, orbit, and zoom with ease.
Important note: In order to export the .json file of a current WUFI Passive file (.mwp), access to WUFI is necessary. While the free version of WUFI does not currently support this function, a new version will be released in the near future that will allow users to export the .json file for use in METr. Stay tuned for updates, and in the meantime, reach out to Phius if you have a file that needs exported, but can’t access WUFI Passive.
This new feature allows users to manually create or import materials, assemblies, and windows. Phius is currently in the process of creating default databases for these components, which will offer a generic range of materials and assemblies for teams to apply to their projects, including the entirety of the Phius Certified Windows database. Currently, the existing WUFI database of materials is already built-in to METr. Users will still have the ability to create and save their own databases which can then be used across all projects stored in the cloud.
A map containing all of Phius’ current climate data sets has been integrated into METr. Simply open the map, enter the project coordinates or locate the project site on the map, then select the appropriate climate data set. Make sure when selecting the climate data set that the project falls within the maximum distance and appropriate altitude range of the weather station.
In addition to these exciting new features of METr, C3RRO and Phius will continue to make ongoing updates and add more features to the tool, the implementation of which will be much faster because the tool is web-based. These planned improvements include:
Phius will release additional blog posts about METr updates as they become available. For any issue or bug reporting, please contact support@c3rro.com. Be sure to also check out the FAQs at the bottom of the METr page on the Phius website and the Phius Launch Webinar for more in-depth information. We appreciate your patience while we continue to develop METr!
