In situ measurements were compared with a numerical model to assess the effectiveness of the model for active envelopes as energy efficient building envelope solutions. There was good agreement for the mechanical flow active envelope, but not for the natural flow variant. States that taking into account the enthalpy change of the cavity air is essential for a correct evaluation of the energy efficiency of active envelopes.
