Four Core Services.
One Precision Methodology.

Energy Performance Certificates (EPC)

Certified EPC assessments under SANS 1544:2014 — mandatory for qualifying commercial and public buildings. We issue A–G rated scorecards based on measured net energy consumption per square metre, enabling direct comparison against SANS 10400-XA:2021 benchmarks.

Compliance is not documentation. It is measured performance. Non-compliance carries penalties of up to R5 million or five years' imprisonment under the National Energy Act.

• Measured energy consumption (kWh/m²/year)
• A–G building performance classification
• EPC scorecard issuance and NBEPR registration
• Mandatory for buildings ≥2,000m² (private) and ≥1,000m² (public)
• First step in the pathway to Net Zero

Energy Management Optimisation

Efficiency is not a once-off intervention. It is a controlled system.

NegaWatt implements structured Energy Management Systems (EnMS) aligned with ISO 50001, incorporating Resource Efficient Cleaner Production (RECP) strategies and continuous performance calibration against established baselines.

• ISO 50001-aligned Energy Management Systems
• RECP — Resource Efficient Cleaner Production
• Continuous performance monitoring and calibration
• Steam, pumping, compressed air, chiller and motor systems
• Energy savings quantified in kWh, GJ, Rand, and tCO₂e

Result

Sustained energy performance improvement and cost reduction.
