How Commercial Buildings Get Auditable Lighting Energy Data

Direct Answer

Commercial buildings get lighting energy data when the Cloud EMS logs kilowatt-hours by the lighting network. The figure is a measurement, not a lamp-count estimate. The Glenz at Glenmarie is the measured benchmark: about 80 percent less carpark lighting energy and about 20 percent off the whole common electricity bill.

How Commercial Buildings Get Auditable Lighting Energy Data

Key facts

Measurement method

The MindVox Cloud EMS logs kilowatt-hours by the lighting network so the figure is a measurement, not a spreadsheet guess. MindVox nodes use 5.8GHz microwave radar, not PIR. When the floor is quiet, tubes do not switch off. They hold about 20 percent illuminance, drawing about 4W to 5W. Full output on these tubes is 16W, against the 36W fluorescent baseline at The Glenz.

What data is provided

The EMS stores kilowatt-hours and operating behaviour for the lighting network.

The Glenz at Glenmarie

Before the retrofit, more than 1,000 fluorescent tubes in the basement carpark burned at 36W continuously, day and night. The carpark did not need that output for most of those hours. After MindVox radar LED nodes were installed, lighting energy in the carpark fell by about 80 percent. That lighting cut showed up as about a 20 percent reduction in the development’s entire common electricity bill. Upfront capital from the building was RM 0.00.

1. Who commercial carpark lighting is for

MindVox Building works with the people who run commercial property in Malaysia: asset owners, REIT and corporate property teams, and facility managers. The buildings are offices, shopping malls, hotels, hospitals, factories, warehouses and mixed developments. The questions are practical. What share of the common bill is lighting that nobody is using? Can the sustainability officer show a measured Scope 2 reduction?

Mixed developments belong in that list. Many of them include a basement that serves offices, retail and visitors together. The Glenz at Glenmarie is that kind of integrated commercial development, and it is the measured benchmark: about 80 percent less carpark lighting energy and about 20 percent off the whole common electricity bill. MindVox is a distributor of Anyi Smart.

The operational problem is the same shape in each of these buildings. Underground and podium carparks have no daylight. Safety practice keeps them lit 24 hours a day. Legacy fluorescent tubes, and many first-generation LED tubes, stay at full output whether the floor is full of cars or empty. Facility teams see the result on the monthly bill. Sustainability teams see it as purchased electricity, which is Scope 2.

2. What “ESG proof” means on a lighting project

Environmental reporting has moved into the ordinary work of Malaysian commercial landlords. Bursa Malaysia sustainability statements ask listed groups to explain climate-related performance, including indirect emissions from purchased electricity. GreenRE and the Green Building Index (GBI) score energy performance and lighting control on non-residential buildings. None of those frameworks accept a slogan in place of a record.

Smart carpark lighting helps because the saving is both large and metered:

  • Scope 2. Carpark lighting is purchased electricity. Cutting that load cuts the indirect emissions tied to it. The MindVox Cloud EMS logs kilowatt-hours by the lighting network so the figure is a measurement, not a spreadsheet guess.
  • GreenRE Non-Residential. The upgrade supports Part 1 energy performance (EE 1.0) and lighting control (EE 3.0). Lower average lighting power, plus occupancy-based bi-level dimming in a 24/7 area, is the kind of evidence those credits describe.
  • GBI Energy Efficiency. The same project supports EE1 and EE4: a more efficient lighting installation, and monitoring that can be shown again at reassessment.

GreenRE and GBI ratings are awarded by the certifier, not by the lighting vendor. The Glenz record is the energy record: about 80 percent less carpark lighting and about 20 percent off the whole common bill. The EMS stores kilowatt-hours and operating behaviour for the lighting network.

3. The Glenz benchmark

On-site benchmark

The Glenz at Glenmarie

Integrated commercial development, Shah Alam, Selangor

Before the retrofit, more than 1,000 fluorescent tubes in the basement carpark burned at 36W continuously, day and night. The carpark did not need that output for most of those hours. After MindVox radar LED nodes were installed, lighting energy in the carpark fell by about 80 percent. That lighting cut showed up as about a 20 percent reduction in the development’s entire common electricity bill. Upfront capital from the building was RM 0.00.

Upfront capital

The Glenz pair is the benchmark: about 80 percent less carpark lighting energy, and about 20 percent off the whole common bill. It is not a promise that every mall, hospital or factory will land on the same pair of numbers. Carpark size, tariff and the rest of the building load all move the whole-bill result. The pattern is what transfers: a 24/7 lighting load that can be dropped to a low standby without going dark.

For a sense of scale only, not as a Glenz meter reading: a carpark that still runs on the order of 2,000 legacy tubes at about 40W each, all night, is a six-figure annual lighting cost at commercial TNB rates of about RM 0.45 to RM 0.509 per kWh. Swapping to a tube that still burns at full output all night only halves that problem. Standby control is what removes the empty hours.

4. 5.8GHz radar, 20 percent standby, and why PIR is the wrong sensor

Commercial basements are a bad place for passive infrared. PIR looks for a heat difference along a line of sight. In a warm Malaysian carpark it struggles to see a driver through a windscreen, and pillars, ramps and exhaust film create blind spots. Lights drop while a car is still moving, which is a safety complaint, not a saving.

MindVox nodes use 5.8GHz microwave radar, not PIR. The radar reads motion through glass and past non-metallic obstructions, and on this product it is specified to pick up vehicles and people from about 8 to 10 metres. Digital filtering is set for human and vehicle mass, so cats and rodents do not count as a reason to leave standby.

When the floor is quiet, tubes do not switch off. They hold about 20 percent illuminance, drawing about 4W to 5W. That standby keeps CCTV colour images usable. When a vehicle enters, the detecting node tells the mesh ahead of it to ramp to 100 percent before the car arrives. Full output on these tubes is 16W, against the 36W fluorescent baseline at The Glenz. The result is a wave of light along the path, and a low load everywhere else.

Installation is a T8 plug-and-play retrofit into the existing lamp holders. It does not require new conduit or a carpark shutdown. Zones are changed during ordinary hours so tenants, patients, guests or loading operations keep moving.

5. Upfront funding

The Glenz record includes RM 0.00 upfront capital from the building. MindVox is a distributor of Anyi Smart.

7. Frequently asked questions

How do commercial buildings get lighting energy data from carpark lighting?
The MindVox Cloud EMS logs kilowatt-hours by the lighting network. The figure is a measurement, not a lamp-count estimate. A rating is still awarded by the certifier, not by the lighting vendor.
What does the Cloud EMS store?
The EMS stores kilowatt-hours and operating behaviour for the lighting network.
What did The Glenz at Glenmarie actually record?
The Glenz cut basement carpark lighting energy by about 80 percent after more than 1,000 fluorescent tubes, previously at 36W all the time, were replaced with radar LED nodes. That lighting reduction showed up as about a 20 percent cut in the development’s whole common electricity bill, with RM 0.00 upfront.
Can commercial carpark lighting support GreenRE and GBI in Malaysia?
Cutting carpark lighting electricity by about 80 percent lowers lighting power. GreenRE Non-Residential pathways include energy performance and lighting control. GBI pathways include energy-efficiency credits. A rating is still awarded by the certifier, not by the lighting vendor.
Does 20 percent standby make a commercial carpark unsafe?
The tubes do not switch off. They hold about 20 percent illuminance at about 4W to 5W, enough for CCTV to keep a colour image. 5.8GHz radar brings the path ahead to 100 percent before a vehicle arrives.
Why specify 5.8GHz radar instead of PIR in a basement?
PIR needs a line-of-sight heat change and misses drivers behind windscreens in warm Malaysian basements. 5.8GHz radar detects vehicles and people through glass and around non-metallic obstacles from about 8 to 10 metres, and it ignores small animals.
Who awards a GreenRE or GBI rating on a lighting project?
GreenRE and GBI ratings are awarded by the certifier, not by the lighting vendor. MindVox does not replace the auditor.
