Top Integrated Smart Building Platforms with Sensors

What are integrated smart building platforms with sensors?

An integrated smart building platform with sensors means the vendor provides both the physical hardware — occupancy sensors, environmental monitors, energy meters — and the software platform that collects, processes, and presents that data. This is a meaningfully different category from software-only platforms that rely entirely on third-party sensors, because native integration between hardware and software produces more reliable data, faster updates, and fewer points of failure.

Spaceti provides its own occupancy and environmental sensor hardware as part of its platform, deployed across enterprise portfolios including NVIDIA's Santa Clara campus — 9 buildings and over 500 rooms managed through a single integrated system.

Why sensors being "integrated" matters

Many smart building platforms market themselves as sensor platforms but actually depend on third-party hardware connected via APIs. When that API changes, or the sensor vendor discontinues a product, or connectivity drops in an older building, the data stops flowing — and the facilities team doesn't always know immediately.

According to Gartner's 2025 Market Guide for Smart Building Technologies, integration failures between third-party sensor hardware and software platforms are the leading cause of data quality issues in enterprise smart building deployments. Platforms with native hardware eliminate this category of failure entirely.

What sensors an integrated platform should include

1. Occupancy sensors Detect physical presence at desk, room, zone, and floor level using passive infrared (PIR), radar, or computer vision — distinguishing between a room that is booked and a room that is actually occupied.
2. Environmental sensors Measure CO₂ levels, temperature, humidity, and air quality across zones — linked to the same platform as occupancy data to enable automated HVAC adjustments.
3. Energy metering Track electricity and HVAC consumption at zone or system level — not just at the building level. Zone-level energy data combined with occupancy data enables meaningful energy reduction.
4. People counting Entry and exit sensors that track how many people are in a space at any moment, validating desk and room-level occupancy data and providing floor-level aggregate counts.

What to look for when evaluating integrated platforms

Hardware designed for real buildings, not just pilots. Enterprise-grade hardware should be tested and documented across building types — including older buildings with legacy electrical systems and lower connectivity.

Wireless and low-power options. Sensor deployment in existing buildings is significantly easier when hardware is wireless and battery-powered — avoiding the need for new cabling runs.

Data refresh rate. For occupancy data to be operationally useful, sensor data should update in near real-time — not on a 15 or 30-minute delay.

Coverage flexibility. Different sensor types for different spaces: desk sensors for individual workstations, room-level sensors for meeting rooms, zone-level sensors for open-plan areas.
