Energy Management
Reduce Energy Costs. Improve NABERS. Take Control of Your Building.
Energy management in commercial buildings is no longer optional. Rising energy costs, NABERS expectations, ESG reporting, and tenant demands mean property managers must understand, and actively manage building energy performance.
At WR8TECH, we combine BMS expertise, HVAC knowledge, and advanced metering to give property managers clear visibility and practical control over building energy consumption.
Unlike traditional energy consultants, we don’t just write reports; we implement, optimise, and maintain.
Why Energy Management Matters
Most commercial buildings waste 10–30% of energy due to:
- Poor control strategies
- Incorrect scheduling
- Simultaneous heating & cooling
- Faulty sensors
- Outdated BMS logic
- Poor plant sequencing
- Lack of sub-metering
A Building Management System (BMS) provides centralised monitoring and control of HVAC, lighting and mechanical systems, allowing energy optimisation while maintaining comfort.
WR8TECH specialises in identifying and correcting these issues.
Our Energy Management Approach
We typically follow a structured approach:
1. Understand the Building
- Review plant and systems
- Review BMS strategy
- Review energy consumption
- Identify operational issues
2. Measure & Meter
- Electrical sub-metering
- Thermal / fluid energy metering
- Tenant metering
- Plant metering
3. Analyse
- Benchmark performance
- Compare operating strategies
- Identify inefficiencies
4. Optimise
- Control strategy improvements
- Scheduling improvements
- Plant optimisation
- Fault correction
5. Monitor & Maintain
- Ongoing reporting
- Performance tracking
- Continuous optimisation
Electrical Energy Metering
You cannot manage what you cannot measure.
WR8TECH installs and integrates:
- Main switchboard metering
- HVAC plant metering
- Tenant metering
- Lighting metering
- Mechanical plant metering
Strategic sub-metering provides clear insight into where energy is being used and whether energy saving initiatives are working.
Energy Audits for Commercial Buildings
Energy Audits (Level 1, 2 & 3)
WR8TECH provides Energy Audits aligned with Australian Standards (AS/NZS 3598).
Energy audits typically fall into three categories:
Level 1 — Walk-Through Energy Audit
Best for:
- Initial review
- Budget planning
- Identifying quick wins
Includes:
- Site inspection
- BMS review
- Energy bill analysis
- Operational review
- Quick win recommendations
A Level 1 audit provides high-level opportunities with estimated savings and is often the first step for buildings that have never been reviewed.
Level 2 — Detailed Energy Audit
Best for:
- NABERS improvement
- Capital planning
- Asset management strategy
Includes:
- Detailed plant analysis
- Control strategy review
- Metering review
- Equipment performance analysis
- Financial modelling
Level 2 audits provide quantified savings and prioritised upgrade recommendations.
Level 3 — Investment Grade Audit
Best for:
- Major capital upgrades
- Large commercial assets
- Portfolio-wide energy strategy
Includes:
- Additional metering
- Detailed data logging
- Simulation modelling
- Investment grade analysis
Level 3 audits provide high-accuracy savings projections and capital justification
Fluid Energy Metering
Energy Management in water
Chilled Water • Hot Water • Condenser Water
One of the most overlooked areas of energy management is thermal / fluid energy.
WR8TECH installs and integrates:
- Chilled water energy meters
- Heating hot water meters
- Condenser water meters
- Tenant thermal billing meters
- Plant efficiency monitoring
Flow meters measure fluid movement in HVAC systems such as chilled water or hot water, enabling energy usage calculation and system optimisation.
This provides:
- NABERS improvement
- Tenant billing capability
- Plant performance measurement
- Efficiency monitoring
- Fault detection
Siemens & Belimo Integration
WR8TECH integrates advanced energy metering devices directly into the BMS.
Belimo Energy Valves & Thermal Meters
Belimo Energy Valves provide:
- Flow measurement
- Temperature measurement
- Thermal energy calculation
- BMS integration
- Tenant billing capability
Belimo Energy Valves integrate directly into BMS platforms using BACnet and Modbus, providing real-time monitoring, control, and energy data.
BMS-Driven Energy Optimisation
Many buildings already have a BMS — but they are not optimised.
WR8TECH specialises in:
- Schedule optimisation
- Plant sequencing
- Demand limiting
- Optimal start/stop
- Economy cycle optimisation
- VSD optimisation
- Chiller optimisation
- Boiler optimisation
WR8TECH designs, upgrades and maintains integrated BMS solutions that combine HVAC, lighting and energy monitoring into a single platform for lower energy costs and improved building performance.
NABERS & ESG Performance
Energy management directly impacts:
- NABERS ratings
- Tenant retention
- Asset value
- ESG reporting
- Operating costs
NABERS Energy ratings are based on actual measured energy data and compare buildings against similar assets.
WR8TECH helps:
- Support ESG reporting
- Improve NABERS ratings
- Reduce base building energy
- Improve tenant energy transparency
What Makes WR8TECH Different
Unlike traditional energy consultants:
WR8TECH:
- Understands controls
- Understands HVAC
- Understands electrical
- Understands plant operation
We don’t just identify problems — we fix them.
