Natural Ventilation in Tall Buildings

Tall buildings in temperate climates can often achieve effective natural ventilation with thoughtful floor planning and limited reliance on mechanical ventilation. Natural ventilation can support indoor air quality and improve comfort through night flushing or evaporative cooling.

Windtech has undertaken natural ventilation studies since the mid-1990s, including wind tunnel modelling, on-site flow measurements, and detailed CFD analysis for large offices and communal spaces.

Designing Around Pressure Differentials

Senior Windtech engineers identify regions of pressure difference across the facade that can drive cross ventilation through apartments or shared spaces. Early collaboration helps the design team capture those benefits without creating conflicts with code requirements or architectural intent.
