Behind architecture
— physics

Computational fluid dynamics simulates the movement of liquids and gases. For building applications, we calculate airflow, pressure and heat transfer to assess comfort, ventilation and equipment performance.

What we assess

External aerodynamics: urban wind flow, wind directions and local acceleration at entrances, courtyards and passages.

What your design team receives

Velocity, pressure and temperature fields at relevant sections; an analysis of problem areas, scenario comparisons and proposals for modifying geometry or systems. We explain which design parameter affects the outcome and how to use the findings.

In cold weather, differences in indoor and outdoor air density create pressure differences along a building’s height. We analyse stack effect to coordinate entrances, vertical connections and ventilation.

What we assess

Vertical pressure distributions and neutral pressure levels under selected temperature conditions.

What your design team receives

Pressure profiles, airflow paths and values across selected doors and zone boundaries. We compare the original scheme with proposed measures, identify the most influential air connections and provide findings for architects and building services engineers.

Compare building options through energy demand and consumption. See how investment in the envelope and systems relates to future operating costs.

What we assess

Heating and cooling demand profiles, heat-gain and heat-loss balances, seasonal and peak loads.

What your design team receives

Energy balances and load profiles, with options compared against agreed indicators. The economic assessment includes initial and operating cost components, stated assumptions and sensitivity to tariffs, schedules and the evaluation horizon.

A flat wall and a real façade junction behave differently. We calculate temperature fields to assess junctions, fixings and mixed-material assemblies before construction details are finalised.

What we assess

Steady-state two- and three-dimensional temperature fields, heat fluxes and local thermal bridges.

What your design team receives

Model definition and boundary conditions, temperature and heat-flux maps, values at selected sections, option comparisons and recommendations for refining the detail. These results support coordination between architects, structural engineers and façade specialists.

Turn an engineering question into a calculation model. Understand how geometry, materials and operating conditions affect a building, and which option deserves further development.

What we assess

Problem definition: identify the decision, variables and performance indicators to compare.

What your design team receives

An agreed modelling approach, scenario results and a comparison of performance indicators. We explain which changes affect the outcome, which inputs are decisive and what to carry into the next design stage.
