Measure the thermal transmittance of materials within a building and determine how well insulated a building element is, with the help of the industry’s most popular U-Value Calculator.
Elmhurst’s U-Value Calculator follows the latest conventions and standards for U-Value calculations, allowing users to accurately calculate valid U-Values for different, walls, floors and roof constructions.
The software has not only been built to work alongside Elmhurst’s Design SAP solutions, to assist new build energy professionals, but it can also be used as a standalone solution to support retrofit projects and energy modelling work.

REQUEST A TRIALU-values represent how well or how poorly a building element transmits heat from the inside to the outside. This is typically shown as W/m² K.
The slower or more difficult it is for heat to transfer through an element, the lower the U-value (which is better for the building).
U-Value calculations are needed by OCDEAs in order to produce an accurate SAP calculation for building compliance. Building Regulations will stipulate the maximum u-value required for each building element.
U-value calculations can also help to inform construction or retrofit strategies.
By completing U-Value Calculations, professionals can appraise and potentially model the thermal transmittance of different building elements, which is important when considering energy efficiency upgrades.
The existing specification and guidance for retrofitting dwellings for improved energy efficiency (PAS 2035), stipulates that U-Value calculations can be used to support initial retrofit assessments.
For traditionally constructed buildings, separate U-Value calculations are even more important as it may not be appropriate for retrofit professionals to accept the default U-values offered by RDSAP software.
We frequently update our materials database to ensure users can select the products they need for their calculations.
