Thermal Analysis & Building Physics

Britain has committed to a more energy efficient future – and lower carbon emissions from buildings will help fulfil that commitment while also helping clients reduce their environmental impact. Thermal Analysis and Building Physics help us gain a fundamental understanding of the physics within the built environment as well as the complex interactions between the climate, architectural form, the building envelope and building services.

At BSD, we have the skills and the latest tools to model and analyse how a building works. This enables us to deliver comfortable and functional internal environments that use natural resources efficiently and exceed the expectations of our clients. In particular, we focus on:

Indoor air quality

While fresh air is essential to the health and comfort of occupants, air movement can bring humidity, heat, pollution and noise into a building. By applying Building Physics technologies – especially dynamic simulation and Computational Fluid Dynamics – we can predict and analyse these factors, controlling air movement to improve both the internal environment and energy efficiency.

Thermal comfort studies

Dynamic simulation helps us ensure comfortable temperatures all year round, whether the building is naturally or mechanically ventilated. The simulation process includes feasibility studies of design options such as free cooling, night time cooling, exposed thermal mass, displacement ventilation and forms of solar gain control. Our work makes sure that clients’ buildings comply with the latest regulations and guidelines, including CIBSE guide A, TM52 adaptive comfort and BB101 ventilation of school buildings.

Moisture and condensation analysis

We can carry out sophisticated analysis to protect the building fabric from moisture and condensation – which can be critical in environments where the contents are sensitive, such as museums.

Visual comfort

Natural daylight increases the comfort of occupiers and also reduces the need for artificial lighting at the same time – which translates directly into lower energy costs. We can carry out daylight calculations to assess the building design and show compliance against BREEAM requirements or the Climate Based Daylight Modelling (CBDM) approach, with the energy savings incorporated into energy modelling.
