Elmhurst launches Online U-Value Software

“The u-value calculator will complete calculations for walls, roofs and floors in line with BS EN ISO 6946, 13370 and BR 443 standards.”

In October this year Elmhurst launched a brand new U-Value calculator application. Unlike previous U-Value calculators that have been packaged within our Design SAP software, the new application is an independent module within our Access Elmhurst members’ area, making it simpler for users who only complete U-Value calculations to access the application.

However, we are mindful that many users of Design SAP also use the U-Value calculator, therefore there is a function to retrieve U-Values from the U-Value calculator into SAP assessments in our Design SAP 10 application.

The U-Value calculator will complete calculations for walls, roofs and floors in line with BS EN ISO 6946, 13370 and BR 443 standards. Kappa values can also be calculated which can then be used in SAP or SBEM assessments for more accurate assessment of thermal mass of building elements. There is an extension materials database available where you can select from generic building elements or from manufacturers products. Of course we have further planned developments for the U-Value calculator in 2023. Further integration options with Design SAP 10 are expected, as well as implementing a condensation risk analysis tool. We will also review our materials database periodically to ensure that it is up to date with any new or revised products that manufacturers release.

Should you have any questions about the u-value calculator please contact the On Construction Support Team who will be happy to assist.
