Wertek AI for commercial buildings

Market context

Mexico and LatAm have tens of thousands of commercial buildings — malls, office towers, hotels, retail chains, educational campuses — operating without a building management system (BMS) or with one installed 15 or 20 years ago that has become a black box: the original integrator is gone, the screens show questionable values, and no one knows which equipment is actually healthy. At the same time, HVAC manufacturers each push their own closed cloud, so a building with equipment from three brands ends up with three dashboards that don't talk to each other. The pressure on the manager grows on three fronts: energy cost (with regulatory penalties for large loads), the comfort of tenants who complain before the operator finds out, and the sustainability reports that owners, funds, and banks increasingly demand. The gap is real: modern, brand-agnostic visibility at a cost the mid-size building can afford.

Sector pain points

The BMS is a black box. It depends on the integrator who installed it; changes cost money, data doesn't come out, and there are signals stuck at ??? that no one has understood for years.
Three brands, three dashboards. HVAC from different manufacturers isn't seen in one place; each brand's cloud only sees its own equipment.
The chillers have no condition monitoring. The building's most expensive asset is serviced reactively; its degradation is discovered with the failure — emergency service, affected tenants.
Manual, contentious energy allocation. Without submetering, the manager splits consumption "by eye," absorbs discrepancies, and argues with tenants.
The tenant notices before the system does. Overcooling, out-of-setpoint zones, and broken sensors operate silently until the complaint — or the bill — arrives.
No independent opinion. The only one who can tell the owner how their BMS is doing is the same provider who sold it.

The Wertek solution

BMS/BACnet visibility audit — the entry product: a passive capture of the building's BACnet network, in read mode and without installing software on the corporate network, that discovers which controllers and points really exist, which data is reliable, and what requires attention. It delivers an independent executive report with findings prioritized in business language — the equivalent of an appraisal or structural inspection, but of the building's nervous system. How it works step by step: buildings.
Energy and submetering: multi-brand meters, consumption and cost estimated with your average price, power quality (power factor, THD, imbalance), and a per-tenant energy portal with the manager's branding — each unit sees its consumption and estimated bill without a Wertek account.
CMMS and field service for the facilities team: the audit's findings become work orders with evidence, automatic preventive maintenance, and contractor-visit logging.
Condition monitoring on the building's rotating equipment (chillers, pumps, air handlers) — vibration and temperature, chiller integration via industrial protocol depending on the site.
Continuous BMS visibility by subscription ROADMAP and HVAC control retrofit ROADMAP.

What Wertek does NOT do in this sector: it does not replace building control — control keeps living in the BMS's local controllers; Wertek observes, audits, and alerts. The audit does not write to the BMS. And Wertek is not an HVAC contractor: mechanical work and commissioning are executed by integrators and contractors, with whom Wertek works as a brand-agnostic platform layer.

Typical assets and sensors

Chillers: integration via industrial protocol (operating parameters) + vibration on compressors and pumps + electrical consumption.
Air handlers (AHU) and rooftop units (RTU): existing BACnet points (temperatures, setpoints, states) and vibration on fans.
VAV boxes and fan coils: discovery and classification via the BACnet audit, with equipment profiles compatible with open industry taxonomies.
Cooling towers and chilled-water/condenser pumps: vibration and temperature on motors and pumps.
Energy meters: main meter, submetering per floor or per tenant, and automatic detection of bidirectional meters where there is solar generation.
Capacitor banks: dedicated monitoring — a natural upsell in malls with power factor issues.

Modalities: BACnet in read mode (audit and discovery), multi-brand energy, vibration on rotating equipment, and on-demand thermography/ultrasound on facilities rounds.

Compliance and standards

Grid Code (Mexico): for large load centers, the platform compares five-minute measurements against the regulatory limits (power factor, imbalance, harmonic distortion) and generates the compliance report — corrected before the fine, with evidence. Detail in Energy.
Sustainability reports and transactions: the audit report and energy data are useful evidence for real-estate due diligence, insurers, and the owner's or fund's ESG reports.
Methodology citing industry standards: the audit's executive report references open building-automation industry standards; HVAC equipment classification uses profiles compatible with open taxonomies.
ISO 55001 (asset management): certification-support module ROADMAP.

Reference case

BMS visibility audit in 29 seconds — Class A tower, Monterrey (published case with verified results, May 2026): in a premium corporate tower whose operator believed they had a "blind" building, a passive 29-second capture discovered 57 controllers and 1,161 points already instrumented that no one was reading; it quantified that only 35% of the analog points evaluated was viable for monitoring that day; it found live two zones in severe overcooling (up to 10.4 °C below setpoint) and broken outdoor sensors feeding the building's automatic decisions; and it delivered a Building Reliability Index of 85/100 with a 30/60/90-day action plan.
