Thermal Energy Modelling

We use IES modelling software on all of our projects to help design cost-efficient and low carbon buildings. Thermal energy modelling allows us to insert all the relevant data about an existing or future building, such as its location, current utility bills, the level of  insulation and its orientation, as well as how exposed it is to the Sun, wind and rain, in order to understand the energy performance of a building.

Once we know the performance based on its exact location, we can start to run different scenarios to understand how to improve the building’s energy efficiency. Instead of suggesting ideas that generally improve energy efficiency, the model will come out with a bespoke solution that works best for that building and its users. For example, we could suggest that we install underfloor heating to reduce heating bills elsewhere and the model may suggest that it would be more cost and energy efficient to only install it in certain rooms. The model also has cost benefit analysis capabilities so that we can choose the best combination of design and materials for a low carbon building that also meets the budget.
