3D Modelling

Three Dimensional modelling Software

At times it is necessary to calculate a point heat loss such as a bracket or balcony penetration. Sometimes a complex steel frame junction with multiple intersecting beams or even variations within a transom / IGU interface need to be accounted for. This will require 3D modelling. We also need to calculate condensation Risk Analysis in 3D and so our application of choice is Trisco.

Sometimes an even finer resolution of analysis is required, so our Solido software provides this with incredible accuracy.

We use this to hold industry standards from:

Key considerations in 3D thermal modelling

  1. Representation of Building Geometry:
    • Architectural Elements: The model incorporates the physical dimensions and characteristics of various architectural elements, such as walls, floors, roofs, windows, and doors, in a three-dimensional space.
    • Material Properties: Different materials have different thermal properties, and the model considers these properties in its calculations. For instance, the thermal conductivity, specific heat, and density of materials influence how they absorb, retain, and release heat.
  2. Simulation of Heat Transfer:
    • Conduction: 3D thermal models simulate heat conduction through building materials and is particularly required for brackets, metal penetrations and heavy steel etc. This also involves the transfer of heat through all other solid structures, like walls and floors, based on their thermal conductivity and thickness.
    • Convection: The model also accounts for convective heat transfer, which involves the movement of heat through fluids (e.g., air). This is particularly important for understanding how air circulation affects the distribution of temperature within a building.
    • Radiation: Thermal radiation, the transfer of heat through electromagnetic waves, is considered in the model. This is crucial for assessing the impact of sunlight and other external heat sources on indoor temperatures
  3. Boundary Conditions and Environmental Factors:
    • External Conditions: The model takes into account external factors such as outdoor temperature, solar radiation, wind speed, and humidity. These factors influence the thermal performance of a building and are crucial for accurate simulations.
    • Internal Loads: Human activities, lighting, electronic equipment, and other internal sources of heat are considered as part of the model to capture the complete picture of thermal dynamics within the building.
  4. HVAC System Integration:
    • Heating and Cooling Systems: The model can be used to simulate the performance of HVAC systems, including heating, ventilation, and air conditioning. This helps in optimising the design and operation of these systems for energy efficiency and indoor comfort.
    • Airflow: Understanding the airflow patterns within the building is essential for assessing how the HVAC system distributes conditioned air and manages temperature variations.
  5. Analysis and Optimisation:
    • Energy Efficiency: 3D thermal modelling allows for the analysis of a building’s energy performance. Design modifications, such as changes to insulation, window placements, or HVAC system configurations, can be tested virtually to optimise energy efficiency.
    • Thermal Comfort: By considering factors like air temperature, radiant temperature, air velocity, and humidity, the model can assess and optimise indoor thermal comfort for occupants.

We we provide 3D thermal modelling we give a comprehensive and detailed analysis of a building’s thermal behaviour, allowing designers, engineers, and architects to make informed decisions for energy-efficient and comfortable building designs.
