• Building systems -- HVAC, lighting, access control -- all in separate vendor portals with no unified view?

  • Energy costs rising with no data showing which systems, zones, or times are driving consumption?

Smart Building Software Development

Smart building software connects HVAC, lighting, access control, energy meters, and occupancy sensors to a unified platform -- and then makes the data from those systems useful for the people who manage buildings and the tenants who occupy them.
We build smart building management software that goes beyond the hardware: energy optimisation dashboards, space utilisation analytics, fault detection and maintenance alerting, tenant-facing portals, and the integration layer that connects building systems that were never designed to talk to each other.

  • Unified platform connecting HVAC, lighting, access control, and energy systems

  • Energy optimisation and space utilisation analytics built on actual building data

  • Tenant portal and facilities management interface in a single platform

  • BACnet, LON, KNX, and MQTT protocol support for existing building systems

Smart building software connects a building's HVAC, lighting, access control, energy metering, and occupancy sensing systems to a unified management platform. It provides building managers with real-time operational dashboards, energy monitoring, fault detection, and maintenance alerting, and gives tenants a self-service portal for access, environment control, and service requests. The goal is to reduce energy consumption, improve space utilisation, and lower facilities management labour costs by surfacing building data in systems that teams will actually use.

Most buildings have smart systems -- HVAC with sensors, access control with logs, energy meters with half-hourly readings -- but the data lives in each vendor's portal, isolated from every other system. The facilities manager doesn't have a single view of the building. The energy manager can't correlate HVAC runtime with occupancy. The tenant can't submit a comfort complaint through a self-service interface.

Smart building software is the integration and application layer that changes this: a unified platform connecting building systems, making their data accessible to the right people, and surfacing the insights that let building managers reduce energy costs, manage space effectively, and respond to building issues before tenants notice them.

What we build

Building management system integration

Integration with existing BMS platforms and building automation systems: Siemens, Honeywell, Johnson Controls, Schneider, and independent BACnet, LON, and KNX controllers. Real-time data ingestion from HVAC, lighting, access control, and energy systems into a unified data platform. Protocol gateway setup for legacy systems without direct IP connectivity. Read-only monitoring integration and, where required, write-back control integration for automated responses to defined conditions. No replacement of existing BMS -- we build on top of what you have.

Energy monitoring and optimisation

Sub-metering dashboards showing energy consumption by floor, zone, system type, and time period -- not just a building-level total. Automated detection of energy waste: HVAC and lighting active in unoccupied zones, equipment running outside scheduled hours, and consumption spikes that indicate equipment faults. Demand response controls that reduce non-critical loads during peak tariff periods automatically. Benchmarking across buildings, floors, or time periods to prioritise the highest-impact interventions.

Occupancy and space utilisation analytics

Space utilisation analytics from occupancy sensors, access control data, and desk booking systems: how many people are in each zone, when, and what capacity that represents against desk or room availability. Reports for space planning decisions -- which floors, zones, or meeting rooms are underutilised, and whether the building layout matches how people actually work. Real-time occupancy dashboards for facilities teams managing cleaning, catering, and security deployment around actual building use.

Access control and security integration

Integration with existing access control systems to surface access data in the unified building platform: door events, badge holder management, and zone access reporting. Visitor management workflows integrated with building access. Integration of CCTV event triggers with the building management dashboard for security teams. Unified audit trails for compliance use cases combining access logs with other building system data. Single interface for facilities teams to manage access policy rather than navigating separate vendor portals.

Tenant portal development

Web and mobile tenant portals giving building occupants self-service access to building services: comfort and environment requests, service request submission and tracking, visitor pre-registration, meeting room booking, and building announcements. Notification delivery for maintenance windows, access changes, and service updates. Feedback and satisfaction collection linked to specific facilities requests. For multi-tenant buildings, per-tenancy data isolation and branded portal options.

Fault detection and maintenance alerting

Automated fault detection from building system data: HVAC operating outside normal parameters, lighting circuits with failures, access control doors held open, and energy consumption anomalies indicating equipment issues. Rule-based and statistical fault detection models that distinguish genuine faults from normal variability. Maintenance workflow integration -- faults that breach thresholds automatically create work orders in your CMMS or FM platform. Prioritised fault queues so maintenance teams focus on the highest-impact issues first.

Frequently asked questions

We integrate with the most common building management and IoT systems: BMS platforms (Johnson Controls, Siemens Desigo, Schneider EcoStruxure, Honeywell), HVAC controllers via BACnet, lighting systems via DALI or KNX, access control systems via REST API or manufacturer SDKs, energy meters via Modbus or M-Bus, and occupancy sensors via MQTT or Zigbee. For legacy building systems without network connectivity, we use protocol gateways or hardware data loggers. The integration scope depends on which systems are installed, what protocols they expose, and what data you need from each. We assess integration feasibility for each system during scoping.

Smart building software reduces energy costs by giving building managers visibility into what is consuming energy, when, and where -- which most currently lack beyond a monthly utility bill. Specific mechanisms include: identifying HVAC and lighting running in unoccupied zones outside operating hours; detecting equipment fault conditions (refrigerant leaks, HVAC running inefficiently) that show up as energy anomalies before they cause failure; enabling demand response -- automatically reducing non-critical loads during peak tariff periods; and providing benchmarking across floors, buildings, or time periods so managers know which interventions had the most impact. Typical outcomes in commercial buildings are 15--30% energy reduction, though this depends on baseline efficiency and the scope of controls integration.

Yes. BACnet (the most common protocol for HVAC and building automation controllers), LON (used in older building automation systems and some lighting controllers), and KNX (common in European commercial buildings for lighting and HVAC control) are all in scope. We use protocol gateways and integration middleware to connect these systems to modern cloud platforms or on-premise servers. We also integrate directly with Modbus for energy meters, M-Bus for utility metering, and MQTT for modern IoT sensors. The integration architecture depends on which protocols your installed systems use and what level of control (read-only monitoring vs read-write control) is required.

A focused smart building management platform -- integrating two to three building systems, energy monitoring dashboard, basic occupancy analytics, and a facilities management interface -- typically runs $35,000--$90,000. Platforms covering multiple buildings, full tenant portal functionality, advanced energy optimisation, fault detection, and integration with property management systems run higher. Cost depends on the number of systems integrated, building count, tenant-facing requirements, and the complexity of the analytics and alerting layer. We scope before pricing and deliver a fixed-cost proposal.
