March 22, 2026 – Canberra, Australia – NCC Update Strengthens Energy Efficiency
The Australian Building Codes Board (ABCB) has announced updated energy efficiency provisions in the National Construction Code (NCC) that require occupancy sensors in all new commercial buildings. The updated code takes effect January 1, 2028, aligning Australian standards with international best practices.
The update follows similar mandates in the European Union, California, and Japan, reflecting a global trend toward occupancy-based building controls.
Key Requirements
Occupancy Sensor Mandate
- All new commercial buildings (Class 3, 5, 6, 7, 8, and 9) must install occupancy sensors in all enclosed spaces
- Sensors must control lighting and, where applicable, HVAC systems
- Lighting must switch off or dim to ≤20% within 15 minutes of space becoming unoccupied
- HVAC systems must reduce energy consumption by at least 30% when spaces are unoccupied
- Manual override must be provided with automatic return to auto mode
Sensor Performance Standards
- Must detect both motion and stationary occupants (presence detection)
- Adjustable hold time (30 seconds to 30 minutes)
- Integrate with building management systems (BACnet or equivalent)
- Self-diagnostic capability with fault indication
- Comply with Australian EMC and safety standards (AS/NZS CISPR 15, AS/NZS 61000)
Compliance Timeline
- January 2028: All new commercial building permits must comply
- January 2030: Major renovations (>50% of floor area) must comply
- January 2033: All existing commercial buildings over 5,000 sq m must retrofit
- January 2035: All existing commercial buildings must comply
Impact on PIR Sensor Market
The Australian market is expected to see significant growth in PIR sensor demand:
- New construction: Approximately 8 million square meters of commercial space annually
- Estimated sensors per square meter: 1 per 50 sq m = 160,000 sensors/year for new construction
- Retrofit market: 100 million square meters of existing commercial space
- Total demand: 500,000-800,000 sensors annually at peak
- Market value: A$50-80 million annually (approx. US$30-50 million)
Technology Preferences
Australian building specifiers are expected to favor:
High-Sensitivity PIR
For offices and educational facilities where seated occupant detection is required, high-sensitivity sensors with 400+ detection zones (like Panasonic PaPIRs+) are expected to be specified.
Dual-Technology Sensors
In spaces with high air movement or obstructions (warehouses, manufacturing), dual-technology sensors (PIR + microwave or PIR + ultrasonic) will be preferred.
Wireless Sensors
For retrofit applications, battery-powered and energy-harvesting wireless sensors are expected to be popular due to lower installation costs.
Energy Savings Projections
The ABCB estimates the updated code will:
- Reduce commercial building lighting energy by 25% (5% of total commercial energy)
- Reduce commercial building HVAC energy by 10% (4% of total commercial energy)
- Lower total commercial building energy consumption by 9%
- Reduce CO2 emissions by 1.5 million tons annually by 2035
- Save Australian businesses A$300 million annually in energy costs
Industry Reaction
“Australia is catching up to global best practice in building energy efficiency,” said a representative of the Green Building Council of Australia. “Occupancy sensors are a proven, cost-effective technology that delivers immediate energy savings. This update will help Australia meet its 2030 emissions reduction targets.”
The Australian Electrical and Electronic Manufacturers Association welcomed the update, noting that local distributors are already stocking sensors that meet the new requirements.
Conclusion
Australia’s adoption of occupancy sensor requirements adds to the growing global momentum for building energy efficiency. With the EU, US, Japan, and now Australia mandating occupancy sensors, the PIR sensor market is set for sustained growth through the 2030s.
