Portfolio sub-metering programme
Roll-out of tenant-level electricity, water and gas sub-metering across a multi-asset portfolio with automated monthly billing data.
Industry · Commercial Property
Smart-building engineering for office, retail and industrial portfolios.
BMS, sub-metering, access, CCTV, backup power, solar and EV — unified into one platform that lifts NOI, protects tenants and produces the data ESG and asset managers actually need.
Industry Challenges
Commercial property runs on NOI, tenant retention and ESG — all measurable, all engineering-driven.
Landlords and property managers are squeezed between rising operating costs, demanding tenants, tougher insurance, ESG disclosure and tighter capex budgets. Promation SA delivers the integrated electrical, automation, metering and security infrastructure that improves all of those metrics under one accountable contract.
Operating cost inflation
Electricity, water, security and maintenance costs rising faster than rental escalations.
Grid instability impact
Load-shedding, dips and surges damaging plant, frustrating tenants and triggering insurance claims.
Unrecovered utilities
Common-area and unmetered consumption silently eroding NOI month after month.
Tenant expectations rising
Enterprise tenants want sub-metering, EV charging, secure access, ESG data and reliable backup — or they renegotiate.
Security & insurance demands
Insurers and corporate tenants want documented access, CCTV, fire and electrical compliance — increasingly tied to premiums.
ESG and disclosure
Funds, REITs and corporate tenants demand measured energy, water and emissions data, not estimates.
Common Operational Problems
What we hear from the plant floor.
01
Recoveries are lower than actual utility cost
Common-area, after-hours and unmetered consumption silently erodes NOI every single month with no audit trail.
02
HVAC running 24/7 in empty zones
Massive avoidable energy spend, accelerated plant wear and tenant complaints about comfort despite the bill.
03
Access, CCTV and BMS as three separate contracts
Three help desks, three SLAs and three monthly invoices for systems that should respond to the same incident together.
04
No portfolio-level view of building performance
Asset managers cannot benchmark, prioritise capex, or report ESG metrics with confidence across the estate.
05
EV chargers retrofitted without an engineering plan
Tripped main breakers, lost tenants and stranded infrastructure that fails as EV uptake grows.
06
Legacy BMS controllers nobody supports anymore
Critical building functions running on hardware with no spares, no licence path and no documented logic.
07
Fault calls handled by 'whoever picks up'
No structured triage, no SLA accountability and no defensible record when tenants challenge recoveries or downtime.

Outcomes we engineer for.
Higher NOI
Recovered utilities, lower energy cost and reduced reactive maintenance spend — measurably.
Resilient operations
Tenants stay operational through grid events, lifts keep running and security stays armed.
ESG-ready data
Measured energy, water and emissions data for fund, REIT and tenant disclosures.
Tenant retention
Sub-metering, comfort, security and EV readiness become reasons to renew — not to leave.

FAQ
Common questions.
Do we have to replace our existing BMS?
Not necessarily. We integrate with what already works and only recommend replacement when the existing platform is end-of-life, unsupported or genuinely blocking operational goals.
Can sub-metering really improve NOI?
Yes. Most portfolios recover unbilled common-area and after-hours consumption within months of accurate sub-metering, and the savings compound through tariff optimisation and demand management.
How do you handle multi-tenant data privacy?
Tenant data is logically segregated, role-based access is enforced, and exports are limited to what each tenant or landlord is entitled to see — aligned to POPIA and ISO 27001 principles.
Can EV charging coexist with our existing supply?
Yes. Dynamic load management distributes available capacity across chargers and other building loads in real time, often deferring or eliminating costly supply upgrades.
Do you support ESG and green-building reporting?
Yes. Automated reports align to GBCSA, EPC and common ESG frameworks using measured rather than estimated data — directly usable in fund and tenant disclosures.
How quickly can you respond to a fault?
Under SLA, response times are explicit and contractually defined. Remote diagnostics and a 24/7 ticketing channel mean most issues are triaged in minutes.
Can you work across a portfolio in multiple cities?
Yes. We deliver portfolio programmes across Gauteng and beyond, with centralised engineering and standardised local execution.
