What "Smart Building" Means
A connected building includes:
- Occupancy sensors — desk, room, floor-level usage tracking
- Environmental sensors — temperature, CO2, humidity, air quality
- Energy sensors — sub-metering by floor, tenant, function
- Maintenance sensors — lift performance, HVAC, plumbing
- Security sensors — access, parking, perimeter
Data feeds a Building Management System (BMS) and increasingly integrates with cloud analytics.
Operational Benefits
Institutional landlords (Mirvac, GPT, Lendlease, Stockland) report:
- 10-25% energy savings (demand-driven HVAC, lighting)
- 5-15% cleaning savings (occupancy-driven scheduling)
- 30-50% reduction in unplanned maintenance (predictive)
- Improved tenant retention (better workplace experience)
Valuation Implications
NABERS Energy ratings depend on metered data. A 5.5-star NABERS rating commands 3-7% premium on lease and capital values vs 3-star equivalent.
For institutional investors (Cbus, AustralianSuper, foreign capital), connected-building data is now table stakes for office and BTR investment.
Brisbane Adoption
Brisbane CBD A-grade stock:
- 2018: ~12% with comprehensive IoT
- 2025: ~32%
- 2030 forecast: ~65%
Smaller stock (B/C-grade, suburban) trails significantly.
For Developers and Vendors
Implications:
- New developments increasingly include IoT as base spec
- Older buildings face capital expenditure to retrofit (~$80-150 per sqm)
- Vendors of older buildings face a "stranded asset" question
- Adaptive reuse / repositioning to BTR or healthcare often includes IoT upgrade

Frequently Asked Questions
Is IoT required for institutional sale?
Increasingly yes for A-grade office, BTR, healthcare. Optional for industrial, B/C-grade.
How much does retrofitting cost?
Approximately $80-150 per sqm for comprehensive IoT and BMS. Higher for full digital twin.
Does IoT data have privacy implications?
Yes — anonymised occupancy data is generally fine; identifiable individual tracking requires consent and complies with Privacy Act.
