Exhaust Systems in Commercial Renovation: Do You Need Make-Up Air and Why It Matters
Exhaust systems are common in commercial spaces such as restaurants, kitchens, clinics, and spas. However, many business owners overlook a crucial component — make-up air.
What Is Make-Up Air?
Make-up air is fresh air introduced into a space to replace air that is being exhausted out. Without it, the space can experience negative air pressure.
Why Make-Up Air Is Important
In Singapore’s enclosed commercial buildings, improper air balance can cause:
- poor indoor air quality
- doors becoming hard to open or close
- uncomfortable working conditions
- strain on air-conditioning systems
- odour issues spreading to neighbouring units
For F&B outlets especially, make-up air helps:
- stabilise kitchen exhaust performance
- improve staff comfort
- reduce heat build-up
- maintain compliance with building requirements
Common Mistake in Commercial Renovation
Many renovation works focus only on exhaust installation, without considering air replacement. This often leads to:
- inefficient exhaust performance
- complaints from staff
- unexpected retrofit costs after opening
Proper Planning Is Key
A proper commercial renovation contractor will assess:
- exhaust volume
- unit size and layout
- existing ventilation
- building management requirements
Make-up air may come from:
- dedicated fresh air ducts
- air-conditioned make-up systems
- controlled intake points
Final Thought
An exhaust system is not complete without make-up air. Proper air balance ensures comfort, efficiency, and long-term operational stability — especially in Singapore’s commercial environments.
