Building Performance and Thermal Modelling

To fully understand the thermal performance of a building and its environmental impact, it’s essential that a detailed dynamic computer generated thermal model is undertaken. Flatt advises Clients, Architects, and Design Teams with regard to how design decisions influence energy consumption, carbon emissions, thermal comfort, daylight, overheating studies and other building performance metrics, and how thermal modelling can therefore facilitate the design.

Steady State and Dynamic Simulation Modelling (DSM)

Our Building Physics team accurately simulate the thermal performance of a building taking due account of design, climate, and use. Building façades can be optimised and plant accurately sized to create efficient and comfortable buildings to live and work in.

Planning applications often require clients to demonstrate how the proposed building addresses their sustainability and low carbon agenda and meets Building Regulations, and this can be achieved through building thermal modelling.

Dynamic Thermal and Simulation Modelling allows us to investigate:

  • Building geometry, including layouts
  • Building fabric performance
  • Façade design
  • Thermal comfort
  • Summer Overheating and solar shading
  • Natural ventilation, airflow and temperature
  • HVAC services installations – sizing and operation strategies
  • Artificial and daylight lighting design
  • Passive design strategies
  • Renewable energy systems
  • Energy consumption and carbon emissions
  • Occupancy profiles and building use
  • Building Regulation and Energy Compliance (Part L, EPC, BREEAM etc)

Computational Fluid Dynamics (CFD)

In complex buildings and spaces, for example, passive buildings, data centres, and atriums, it’s essential to obtain a more detailed understanding of the internal environment. Using CFD modelling, we can design and specify systems to meet the exacting requirements of these spaces as follows:

  • Internal airflow simulations to assess natural and mechanical ventilation systems effectiveness
  • Effectiveness of passive thermal stores, exposed slabs, night cooling strategies
  • Detailed assessments of thermal comfort at varying locations though a space
  • Airborne contaminant dispersal studies
  • Data centre room cooling strategies to avoid hot spots, size plant, heat dispersal from racks
  • Model effect of Plant failure on the internal environment
  • Displacement ventilation strategies
