Optimizing façade design regarding ventilation and acoustic performance
In tropical countries, air conditioning systems are widely used to improve indoor climate. However, in most cases, natural ventilation can provide sufficient thermal comfort for the users. Though, openings in the façades for natural ventilation decrease the sound insulation. Hence, the outdoor noise can affect the acoustic comfort indoors.
This is especially important for classrooms, in which speech intelligibility plays an important role. Intelligibility is mainly compromised by background noise due to outdoor sounds.
The goal of the proposed work is to simulate different wall designs regarding the surface area, the geometry and the density of openings in order to find an optimized design for classrooms façades. The idea is to use Boundary Element Method to simulate sound transmission patterns for each parameter set. These can subsequently be implemented in a framework aiming the auralization of classroom designs.
