What we deliver
Twara Technologies builds monitoring systems for offices, campuses, hospitals, hotels, retail sites, warehouses and residential complexes. We bring together electricity, water and gas metering, environmental sensors and data from existing building systems, and turn them into dashboards, alerts and reports that facilities, sustainability and finance teams can use. The goal is a building that is understood: where energy goes, which systems misbehave, which spaces are used, and whether changes are working.
This service suits facilities managers, property owners, sustainability leads and operators of multi-site portfolios. You do not need a fully instrumented building to start: a few well-chosen meters and sensors, combined with data already held in your building systems, often reveal the first improvements worth making.
Typical scope
- Survey of incoming supplies, distribution boards, meters, plant rooms, BMS and network infrastructure.
- Metering plan: main and sub-meters, current transformers on major loads, and pulse or digital outputs from utility meters.
- Environmental sensing: temperature, humidity, CO2, particulates and light, placed for representative readings.
- Occupancy and utilisation sensing using privacy-preserving methods.
- Integration with BMS, chillers, air-handling units, lifts, generators, solar inverters and battery systems.
- Normalised data model for sites, floors, zones, equipment and meters.
- Dashboards, alerts and periodic reports, including tenant or department recharging where needed.
Technologies we work with
- Building protocols: BACnet and Modbus are widely used in building automation and metering; we also work with KNX and vendor APIs where installed. Read-only access is the default.
- Wireless sensors: LoRaWAN for battery-powered sensors spread across large buildings or campuses, which the LoRa Alliance designed for low power and long range; Bluetooth Low Energy or Wi-Fi where coverage and power suit them.
- Smart home and small-premises devices: Matter, the Connectivity Standards Alliance’s IP-based protocol over Wi-Fi and Thread, where residential or small-commercial interoperability matters.
- Messaging and platform: MQTT into a cloud or on-premises platform with a time-series store. See IoT Platforms & Dashboards for how we build that layer.
- Visualisation: custom web dashboards for occupants and management, Grafana for engineering views, and exports to spreadsheets or BI tools.
How we choose: reuse what is installed, use wired connections in plant rooms and wireless sensors in occupied spaces, and keep data in open formats so you are not tied to a single sensor vendor.
How we approach it
- Baseline. Collect existing bills and BMS data to understand current consumption and comfort complaints.
- Survey. Walk the building with the facilities team and record meters, systems, network points and access constraints.
- Plan metering and sensing. Decide what to measure, where, and at what interval, linked to specific questions.
- Install and integrate. Coordinate with electrical contractors for meter fitting and with the BMS vendor for data access.
- Validate. Check readings against utility meters and spot measurements before anyone relies on them.
- Act and review. Agree a small set of measures with the facilities team, track their effect and refine rules and dashboards.
Energy codes in India
India’s Bureau of Energy Efficiency publishes building energy codes, including the Energy Conservation & Sustainable Building Code 2024 (ECSBC 2024). Whether and how a code applies to a particular building is a question for your architect or energy consultant and the local authority, so we work with them on what applies. Our role is to provide the metering, monitoring and reporting that help demonstrate and sustain performance.
Security, privacy and quality
- Building networks segmented so that monitoring gateways cannot be used to reach control systems; write access to plant is never granted by default.
- Sensors and gateways configured against ETSI EN 303 645 provisions such as unique credentials, secure communication and keeping software updated.
- Occupancy data aggregated and anonymised. Where any data can identify people, we design for the principles set out with India’s DPDP Rules, 2025, including data minimisation and storage limitation.
- Every meter and sensor is commissioned with a recorded location, scaling factor and validation result.
Engagement options
- Building assessment: a survey and monitoring plan for one site or a representative sample.
- Single-site deployment: design, integration, dashboards and handover.
- Portfolio rollout: templated deployment across many sites with a common data model and benchmarking.
- Ongoing monitoring support: data quality checks, rule tuning and periodic insight reviews.
