Uvalue modules

The Uvalue modules calculate the thermal transmittance of building elements in order to predict the rate of conduction heat loss through the element. The resulting U-values are used in SAP calculations and also for compliance with Building Regulations.

JPA Designer Uvalue modules make calculation straight-forward, with construction elements built-up layer by layer; a process made easier by the comprehensive database of generic and branded materials. The modules also include a 'variable layer' feature which makes it easy to compare the effect of design changes on the thermal performance.

Education discounts are available for U-value modules. <Click here for more details>

Sole trader discounts are available for the U-value Professional 2010 module and the U-value Professional 2010 + SAP 9.90 bundle. Contact us for more details.

Uvalue Professional 2010

£340.00 + VAT (includes first year's licence fee)
Annual licence fee: £50.00 + VAT

Calculates U-values for:

Walls, roofs and floors (ISO 6946 'combined method');
Lightweight steel framed elements (BRE Digest 465 method);
Ground floors and basements (ISO 13770 method).

The module also performs interstitial condensation risk analysis to ISO 13788 and BS 5250:2002. As the software uses the same initial data for U-value and condensation risk calculations it is easy to analyse heat loss and condensation risk for the same element.

Uvalue 2010

£260.00 + VAT (includes first year's licence fee)
Annual licence fee: £50.00 + VAT

Calculates U-values for:

Walls, roofs and floors (ISO 6946 'combined method');
Lightweight steel framed elements (BRE Digest 465 method);
Ground floors and basements (ISO 13770 method).

The module can calculate all the U-values required for SAP calculations.

Materials database & Templates

The integral database in all JPA Designer U-value modules includes branded products and generic materials, and is designed to help users carry out U-value calculations without having to search for data.

The Materials database & Templates presents designers with key data about products at the point at which they are experimenting with ways of maximising the thermal performance of the building elements.

The Materials database & Templates can be customised to suit your individual requirements. If you are a construction product manufacturer you can have your products included in the database. Click <HERE> or on the link in the left column for more details.

The BBA operates a Scheme for assessing and monitoring
U-value and condensation risk calculation competency; it seeks to promote and assist accurate, objective and consistent calculation of U-values and condensation risk within buildings.

JPA TL supports the scheme, and scheme members can use JPA Designer to display the scheme logo on the outputs from U-value and condensation risk calculations. Click on the logo for more details.
