Performance louvres are sometimes also known as ventilation louvres. For ventilation (or “performance”) louvre systems, the main objective is to allow air to pass through, while protecting against rain or water entry and, in some cases, preventing breakout or break-in noise.
Conflicting technical criteria in the industry has made specifying performance of these louvres tricky. In our experience, here’s what architects and building designers should look out for:
1. Rain Defence Effectiveness
Based on the louvre effectiveness score, performance louvres are sorted into rain defence classes, with “A” being the most effective in preventing rain penetration, and “D” being the least effective.
2. Airflow Effectiveness
The aerodynamic coefficient, derived from wind tunnel testing, is used to calculate the airflow effectiveness of a performance louvre. The higher the coefficient, the more air passes through freely.
It is the only accurate method that provides a true comparison of performance, and should be used in designing the actual airflow requirements of a building during detailed design. It should not be confused with free area percentage, which is a suitable method at the building planning stage only.
3. Noise Reduction Effectiveness
Acoustic louvres are measured for transmission loss at Octave Band Centre Frequencies. 6dB is added to transmission loss values to get the free-field noise reduction ratings.
Acoustic louvres can sometimes also be given a Weighted Sound Reduction Index or “Rw” rating, expressed in decibels. The higher the Rw figure, the better the sound insulation provided.
a. Site location and exposure
b. Local weather conditions
c. Location and exposure of louvres on building
d. Airflow rate and direction through louvres
e. Maximum acceptable pressure drop
f. Degree and depth of water penetration acceptance
g. Any special solutions for sloping applications
h. Aesthetic appearance
Sustainability standards such as the internationally-recognised LEED certification (USA) and BCA Green Mark 2021 (Singapore) are increasingly becoming a vital benchmark for buildings. They signal a fundamental shift towards environmentally conscious design and construction, assessing buildings across metrics like energy efficiency, materials selection, water conservation, and indoor environmental quality. Building designers working towards these sustainability standards cannot ignore how performance louvres are critical in making our buildings comfortable and cost and energy-efficient.
One-size-fits-all no longer cuts it. With LEED accredited experts and experience designing for standards in Asia, USA, and the UK, INNIVATE’s performance louvre systems are beautiful, bespoke solutions that are more than skin deep; they are made from fully recyclable aluminium too. It’s our responsibility to create buildings that are not only beautiful, but sustainable and healthy for both occupants and the environment.
