Energy Management

Energy audits, smart metering, performance monitoring and compliance reporting — followed by the optimisation and renewable strategy to act on the findings.

You cannot reduce what you do not measure.

The problem

Most facilities receive one number a month: the total on the municipal bill. That number cannot tell you which chiller is failing, which tenant is subsidising another, or whether last year's lighting retrofit actually paid for itself. Meanwhile tariffs climb and load-shedding turns a comfort problem into an operational one. Metering and auditing turn a single number into decisions.

What we do

Energy Management: the scope in detail.

Measurement and data tracking

Smart meters, sensors and software that track electricity, gas and water consumption in real time — per building, per tenant, per system — so consumption is attributable rather than argued about.

Energy audits

Assessment of current energy performance to identify energy-intensive processes and pinpoint inefficiencies, including support for Energy Performance Certificate (EPC) requirements.

Optimisation strategies

Implementing energy-saving technology — LED lighting, upgraded HVAC, automated controls — to cut waste without affecting productivity or occupant comfort.

Renewable integration

Planning and transitioning toward clean energy sources such as solar, sized against measured demand rather than a guess at the roof area.

What you receive

Not a promise. A document.

Energy audit report with consumption baseline and load profile
Prioritised savings register — intervention, indicative cost, expected saving, payback
Sub-metering installation with per-tenant or per-system attribution
Monitoring dashboard and monthly performance reporting
EPC compliance support documentation

Standards we work to

SANS 50001 / ISO 50001 — energy management systems principles
SANS 1544 — Energy Performance Certificates for buildings
Regulations for the Mandatory Display and Submission of Energy Performance Certificates
SANS 10142-1 for all associated electrical work

Typical timeline

A walk-through audit takes 1 to 2 days on site with the report inside two weeks. Metered baselining needs a minimum of one full billing cycle before conclusions are reliable — we will say so rather than report early.

Questions

Asked often.

Does my building need an Energy Performance Certificate?

South African regulations require EPCs to be displayed for certain categories of building above defined floor areas, including many offices and public-sector buildings. We assess whether your building falls in scope and prepare the supporting data.

What kind of savings are realistic?

It depends entirely on the building's current condition, and any contractor quoting a percentage before measuring is guessing. Lighting, HVAC scheduling and control tuning are usually where the fastest payback sits. Our estimator gives an indicative range; the audit gives you the real number.

Can you install solar?

We plan and deliver the transition to clean energy sources including solar. We size the system against measured demand from the audit, which avoids the two common outcomes — a system too small to matter, or one too large to ever pay back.

How does sub-metering help with tenants?

It replaces an apportioned estimate with a measured reading. Recovery becomes accurate, disputes drop, and heavy users become visible instead of subsidised by everyone else.
