Thermal Simulation Services
From Technical Services
BM TRADA offers a thermal simulation service for modelling the thermal performance of external doors and windows to BS EN ISO 10077-2 and BFRC requirements.
Thermal simulation is able to substitute materials within the product design without any physical testing. This helps to achieve the desired performance for the lowest cost, as well as addressing the material and glazing variants that exist within any range of products.
Simulation is carried out via computer modelling. In order to carry out a simulation the manufacturer needs to supply geometry and technical details of the product.
Thermal simulations are used to calculate U-Values for doors and windows for:
- Compliance with Approved Document Part L - U-Values for doors and windows need to be included in the calculation of the overall energy performance of the building as part of meeting Building Regulations.
- CE marking - thermal performance is a mandatory requirement, so U-Values verified or produced by a Notified Body will be needed as part of any Declaration of Performance.
- Achieving a BFRC Energy Rating - BFRC energy ratings can now be used to demonstrate compliance with some parts of Approved Document Part L by assessing the total energy performance of a product. The energy efficiency of the product is not purely determined by its ability to minimise the transfer of heat, a number of factors, including solar heat gain and air permeability also have an impact.
BM TRADA is BFRC Independent Agency number 001 and can provide third party certification of thermal performance based on energy rating calculations and specifications through initial assessment and continual monitoring of the manufacturer's production process.
