Energy data that turns into energy savings

Every meter, submeter, and load already flows into xSERVA through BACnet, MQTT, and Modbus — so energy management runs on the same live data as monitoring and alarms, not a separate spreadsheet exercise assembled once a month.

Consumption analytics

xSERVA breaks down consumption by zone, system, and time period, so a spike shows up as a specific AHU running outside schedule rather than a single number on a monthly bill. Trends are tracked continuously, letting facilities teams spot creeping waste — equipment left running after hours, a chiller operating below its efficient set point — long before it shows up as a meaningful cost.

Demand response & load shedding

When consumption approaches a demand threshold or a tariff period changes, xSERVA can automatically shed non-critical load — deferring pre-cooling, staggering equipment start-up, or dimming non-essential lighting — based on rules the facilities team defines and can override at any time. This keeps peak demand charges down without requiring a person to be watching a dashboard at the right moment.

As the peak tariff period opens, xSERVA defers pre-cooling by forty minutes and dims car park lighting to sixty percent, so the managed curve stays below the 520 kW demand threshold that the unmanaged curve would have crossed. Critical load is never shed.

Carbon & ESG reporting

Because consumption, equipment runtime, and occupancy data all live in the same platform, xSERVA can generate carbon and ESG reports directly from operational data instead of a manual reconciliation exercise. Reports roll up by site or across a portfolio, giving sustainability teams a consistent, auditable basis for internal targets and external disclosures.

A quarterly carbon report line of 318.4 tonnes CO2 equivalent drills into the lighting contribution of 62.9 tonnes, then into the individual points that produced it: a KNX dim level, a Modbus lighting submeter reading and an MQTT occupancy count. The report is structured for GBI Malaysia, Green Mark, LEED and BREEAM, and draws on the same live data as daily operations, so there is no separate collection exercise before an audit.

Aligned with the standards that matter

xSERVA structures energy and consumption data to support reporting under GBI Malaysia, Green Mark, LEED, and BREEAM — the green-building rating frameworks most commonly required across South East Asian and international portfolios. The platform does not issue certification itself; rating bodies retain that authority. What xSERVA provides is the consistent, granular operational data each framework’s reporting requirements are built around, so preparing a submission draws from live records instead of a one-off data-gathering project.

Sustainability, by role

  • Property Developers & Architects benefit from specifying one energy-aware platform at design stage instead of bolting on sustainability reporting after handover.
  • Building Owners & Operators use consumption analytics to cut operating cost per square foot without new capital equipment.
  • System Integrators deploy demand-response logic once, against unified data, instead of custom-coding it per protocol on every project.
  • Enterprise & Corporate portfolios standardize ESG reporting across every site with consistent, auditable data instead of a spreadsheet per building.
  • Government & Institutional sites use built-in alignment with recognized green-building standards to support compliance and public reporting mandates.

Lighting

The cheapest kilowatt is the one the sun already delivered

Lighting is usually the second largest electrical load in a commercial building and the easiest to waste, because a fixed-output installation runs the perimeter at full power on a bright afternoon. Daylight harvesting holds the same illuminance target at every desk and varies only the electric contribution. It needs two things that are unglamorous and decisive: a sensor that measures the actual lux at the working plane, and per-luminaire addressing so the response is a bay rather than a whole floor.

A section through one office floor divided into three lighting bays, all holding the same 500 lux target at desk level. The perimeter bay receives 780 lux of daylight and dims to 20 percent, drawing 0.9 kilowatts. The middle bay receives 310 lux and dims to 55 percent, drawing 2.4 kilowatts. The core bay receives 40 lux, runs at 90 percent and draws 4.1 kilowatts. Each bay has a ceiling sensor combining lux and occupancy, with DALI-2 addressing every luminaire individually and KNX carrying the room scene and switch input. Notes record that the perimeter bay saves about 3.2 kilowatts against a fixed-output installation while daylight lasts, on the order of 6400 kilowatt hours a year for one bay, and that a failed DALI driver reports itself so a dark fitting becomes a maintenance ticket rather than a complaint.

From reactive to proactive energy management

Traditional energy management is retrospective: a facilities team reviews last month’s bill, notices a spike, and starts asking what happened three weeks after the fact. By the time the anomaly is understood, the waste has already been paid for. xSERVA closes that gap by keeping consumption analysis continuous rather than periodic, so a deviation from expected load shows up as an alert the same day it starts, not as a line item at the end of a billing cycle.

This shift matters most in mixed-protocol buildings, where a chiller on BACnet, lighting on KNX, and a submeter on Modbus have historically lived in separate reporting silos. xSERVA reads all three through the same unified data model that also drives monitoring and alarms, so an energy anomaly in one subsystem can be correlated against occupancy, schedule, and equipment status in another — turning a raw consumption number into an explainable, actionable insight.

Built for the review that follows the report

A report only creates value if someone can act on it. xSERVA’s energy and ESG reporting is structured so that every summary number links back to the underlying zone, system, and time period it came from, letting a facilities manager or sustainability lead drill from a portfolio-level chart down to the specific AHU or lighting circuit driving it. That traceability is what turns a compliance report from an annual obligation into a working tool the operations team actually uses month to month.

Because reporting draws on the same live data as day-to-day operations, there is no separate data-collection exercise to run before an audit or a green-building resubmission. The numbers a rating body sees are the same numbers the operations team has been working from all along, which keeps the reporting process defensible and consistent year over year.

Frequently asked questions

Does xSERVA replace our utility metering?

No. xSERVA reads from existing meters and submeters over BACnet, MQTT, or Modbus and layers analytics, demand response, and reporting on top of that data, rather than replacing your metering infrastructure.

Can xSERVA automatically shed load?

Yes. Demand response and load-shedding rules can trigger automatically based on live consumption, tariff periods, or grid signals, with operators able to review and override any automated action.

Which sustainability standards does xSERVA support reporting for?

xSERVA structures energy and consumption data to align with GBI Malaysia, Green Mark, LEED, and BREEAM reporting requirements, though certification itself is issued by the respective rating body, not by xSERVA.

Are the energy savings figures on this page guaranteed?

No. Any figures shown on this page are illustrative examples and will be replaced with verified customer data as case studies become available. Actual results vary by site, equipment, and occupancy pattern.
