SOLUTION / SMART OFFICES & MEETING ROOMS

“Ghost bookings” hold meeting rooms,
Desk utilisation still relies on gut feel

SMART OFFICE & MEETING ROOM

Real occupancy of desks and meeting rooms, illuminance, temperature & humidity, door/window and leak status all go to the cloud; bookings auto-release on actual use and lighting/HVAC follow people.

Three blind spots in office space

WHAT GOES WRONG TODAY

Rooms are booked but left empty

The booking system sees the calendar but not the room: empty bookings block others and desk ratios lack real data.

Lighting and HVAC run all day, floor by floor

Empty areas still consume power, while window zones with ample daylight remain fully lit.

Open doors/windows and pantry leaks are noticed late

Without state sensing, issues are found on the next day's patrol and energy or facility risks can only be reviewed after the fact.

Three-layer architecture: sensing → gateway → platform

SYSTEM ARCHITECTURE
Three-layer architecture: battery-free sensing, EnOcean gateways, the unified IoT platform, PC console, device app and business mini-program

Sensing layer · battery-free

PIR and presence, illuminance, temperature & humidity, door/window contacts, water leak, CO₂ and multi-function controllers

Network layer · EnOcean

868 MHz wireless; gateway uplink via Wi-Fi / Ethernet / 4G, reusing existing Aruba APs

Platform layer · private deployment

Desk and room booking, auto-release and energy dashboards, with DingTalk, WeCom and Feishu integration

Six functions that let spaces report themselves

WHAT YOU GET

Desk occupancy sensing

LD-OSB / LD-OSP detect whether a seat is occupied, including stationary people, and report true utilisation by floor and department.

Automatic meeting room release

Sustained inactivity during a booking releases the room by rule and writes back to the booking system, cutting empty bookings and raising bookable capacity.

Daylight-linked dimming

LD-ILB measures daylight and works with 0–10 V dimmers to hold target illuminance, prioritising daylight near windows.

Temperature, humidity & HVAC interlocks

LD-TH / LD-MFC collect ambient data and drive VRV controllers to switch HVAC and set temperatures by occupancy policy.

Door/window & leak alerts

LD-MC counts open/close events while LD-FS / LD-LDU watch for leaks in pantries, shafts and server rooms with instant alerts.

Energy & space review

Occupancy and energy reports by floor, department and time of day support desk ratios, floor-area adjustments and energy KPIs.

TYPICAL BILL OF MATERIALS
LD-OSBLow-power PIR · desk & seat occupancy · adjustable 120° detection
LD-OSPPresence · non-contact temperature · detects stationary occupants
LD-ILBWireless illuminance sensor · 20–1,000 lux · lighting interlocks
LD-THBattery-free wireless temperature & humidity · indoor light powered · configurable 15-min reporting
LD-MFCWireless multi-function controller · CO₂ · ambient temperature setpoint · boost button
LD-MCBattery-free wireless door/window contact · indoor light powered · open/close state and frequency
LD-FSElectrode water leak sensor · pantry and shaft leaks · customisable probe cable
LD-D010Wireless 0–10 V dimmer · connected to the lighting bus for grouped dimming
LD-GW01EnOcean gateway · up to 50 devices per unit

Typical configuration only. Point density depends on desk layout, partition height and existing network conditions; add LD-Repeater units for cross-floor or long-range scenarios.

What changes in management after rollout

WORKPLACE

From lighting by floor to lighting by person

Lighting and HVAC policies follow real-time occupancy; window zones dim to daylight and per-zone energy is metered separately, so savings can be verified before and after.

MEETING ROOMS

Booking data finally matches actual use

Empty meeting rooms auto-release by rule; utilisation reports replace gut feel and inform desk ratios and leasing decisions.

Validate on one floor, then replicate across the building
