The Problem

Modern Buildings Create Modern Power Problems

Commercial buildings have never been more electrically efficient on paper — VFD-controlled HVAC, LED lighting with smart dimmers, high-density IT loads, and EV charging infrastructure. But every one of these technologies creates harmonic distortion that wastes energy and degrades the very systems designed to save it.

The result: inflated electricity bills, shortened equipment life, lift ride-quality complaints, and — critically — a neutral conductor fire risk from triplen harmonics that building managers rarely know about.

What Causes It

The Triplen Harmonic Problem

LED drivers and switch-mode power supplies generate triplen harmonics (3rd, 9th, 15th order) that don’t cancel in the neutral conductor — they add. In buildings with extensive LED lighting, neutral current can reach 1.5–1.7x the phase current, overheating conductors sized for much lower loads. This is a genuine fire risk.

VFDs on HVAC and lifts add 5th and 7th harmonics. EV chargers contribute rectifier harmonics at 60–70% THD per charger.

Why this affects property value + Read more− Close

Operating costs directly impact Net Operating Income (NOI), which determines property valuation through capitalisation rates. A $41,000 annual energy saving capitalised at 6% adds $685,000 to property value. Upcoming EPC regulations (proposed minimum B rating by 2030) mean buildings with poor electrical efficiency face obsolescence risk. Power quality optimisation improves real energy performance, protecting long-term asset value.

The Solution

How HarmoniQ Works

HarmoniQ uses narrowband tuning technology to maintain clean, efficient power across your building. Sampling 20,000 times per second, the system eliminates harmonic distortion that wastes energy, overheats conductors, and degrades equipment.

Tier 1
HarmoniQ Filter

Eliminates triplen harmonics that overload neutral conductors — addressing a genuine fire risk. Reduces total THD below 5%, extending HVAC, lift, and LED driver life.

HarmoniQ Filter
Tier 2
HarmoniQ Alpha

Stabilises voltage during chiller starts, lift operations, and EV charger cycling. Improves lift ride quality and eliminates LED flicker that affects tenant comfort.

HarmoniQ Alpha
Tier 3
HarmoniQ Booster

Corrects power factor to 0.98+, eliminating reactive charges and freeing transformer capacity for EV charging expansion without costly infrastructure upgrades.

Common Misconceptions

What We Hear — and the Reality
Myth
“Our building is only a few years old — power quality can’t be an issue.”
Reality
Newer buildings often have worse power quality because they’re packed with VFDs, LED dimmers, and EV chargers. Modern energy-efficient equipment is more efficient at its job, but generates more harmonic distortion as a side effect. The building’s age is irrelevant — its load profile determines its power quality.
Myth
“Our energy bill is small compared to rent — it’s not worth optimising.”
Reality
At a 6% cap rate, every $1 saved on operating costs adds $21 to property value. A $41,000 annual saving becomes a $685,000 valuation uplift. Add the EPC compliance benefit (proposed minimum B by 2030) and the fire risk reduction from neutral overloading, and this is an asset protection investment, not just an energy one.
Myth
“We can’t add EV chargers — our transformer is at capacity.”
Reality
Power quality correction typically frees 15–20% of transformer capacity by eliminating reactive power and harmonic losses. That’s often enough to add 10–20 EV chargers without a transformer upgrade — saving $127,000+ in infrastructure costs while meeting tenant and regulatory demands.
