‘We wanted to prove we didn’t need air conditioning’: the airport cooled by natural ventilation

What matters is the decision you can examine, the evidence you can gather and the limits you should keep in view.

01 / Relevance

What this could mean

The terminal’s design suggests natural ventilation could reduce reliance on mechanical cooling in some airport spaces. For UK operators, the relevant signal is that building form and local conditions may shape comfort and energy demand, not that this approach will suit every site.

02 / Evaluation

How to judge its significance

Its significance would depend on measured indoor comfort, humidity, airflow and energy use across seasons and busy periods. It may be less relevant where external air quality, noise, security needs or the building layout limit reliable ventilation.

03 / Learning

What to take from it

Passive design works as a system, rather than as a single feature: airflow paths, occupancy and local climate all affect whether a space remains usable. A design claim is more transferable when supported by evidence from actual operating conditions.

04 / Application

Use this in your organisation

For a planned refurbishment, identify one suitable occupied area and ask the building team to assess whether natural ventilation could maintain comfort there. Keep the review exploratory, and compare it with the existing cooling approach before committing to changes.

05 / Evidence

What would test the idea

What monitoring would show that the area stays within the organisation’s comfort range during peak occupancy and varied weather? Seek evidence on temperature, humidity, airflow, occupant feedback and cooling energy, and establish who would respond if ventilation proved insufficient.
