Thermal Modelling
Dynamic Simulation Modelling

Thermal modelling enables you to understand the performance of a building through a computer-generated model, allowing projects to further understand the energy consumption, carbon emissions, comfort, overheating & daylight factors that impact a project

Thermal Modelling

During the planning application process, it is often required to show how the proposed development will meet a number of criteria such as carbon emissions & sustainability, By undertaken thermal modelling in the concept stages of a project we can ensure that early strategies can be implemented to address the relevant criteria,


Similarly, recognised assessment procedures such as BREEAM will be able to obtain credits by demonstrating how the building operates and from this can be used to achieve credits towards your BREEAM rating.


Thermal modelling is the process of replicating the proposed development through the use of a computer-generated model, including Thermal Elements, Constructions, HVAC, Lighting, Daylighting, Orientation, Building use & type and much more, this enables the model to be used to improve and develop real-life scenarios and therefore meet criteria set out such as BREEAM or Net-Zero.


Understanding how the development works and performs will enable decisions and strategies to be implemented at an early stage and therefore the overall development can benefit from lower carbon and highly efficient designs.


Another potential reason behind thermal modelling is to support the planning application in the production of an energy & sustainability statement, thermal modelling can be used as a great tool to be able to design a project as close as possible to how the dwelling will ultimately perform and therefore can achieve carbon reductions or thermal comfort.

What are the next steps?

If your project is currently working toward planning or has gone through planning and further conditions have been set on the project, thermal modelling could be the next step depending on the requirement of the project, if you have a project and have initial concepts we will be able to assist, we encourage early involvement as much as possible, this allows early concept designs to take shape and we can assist in developing the design. Feel free to give us a call or send across your project details, we will be more than happy to help.
