Innovation

When your building is ready, the hardware takes over.

Algi starts with software. When the data shows it makes sense, the hardware layer adds real-time monitoring, building connectivity, and active air quality improvement. Everything is leased. Nothing lands on your balance sheet.

Bio Wall

A living panel that works on your air quality

The Algi Bio Wall is a 4ft by 4ft wall-mounted panel containing living Spirulina culture behind a woven fabric face. The culture actively processes airborne particulates and CO2 as part of the building's air handling. It is designed to complement HVAC, not replace it.

In controlled testing, the Bio Wall has shown HVAC load reductions of 25-30%* per room and approximately 10%* at property level when integrated with the building's air handling system.

*Illustrative range based on controlled environment testing. Results vary by building type, occupancy, and HVAC configuration.

Patent application GB2404515.5 pending.

The Bio Wall is designed for offices, hotels, restaurants, retail, and residential spaces.

Material and craft

The front face is a woven fabric panel that allows air exchange while containing the Spirulina culture. The frame is precision-machined from sustainable materials. The panel connects to the building's fresh air supply via the Algi Hub and operates continuously without manual maintenance.

Algi Hub

The building's nervous system

One Hub per property. It connects to your existing building systems over WiFi, Modbus, BACnet, Zigbee, and BLE. It reads any wireless device on the property network and feeds data to the Algi platform. If you have a Sense unit, a Bio Wall, or a smart meter, the Hub is what ties them together.

Raspberry Pi-class compute. No cloud dependency for local control loops. Included in Pro and above.

Algi Sense

The room-level sensor

Algi Sense measures temperature, humidity, CO2, and PM2.5 continuously. Battery powered, wireless, installs in minutes. Each unit reports to the Hub or directly to the Algi platform over WiFi. Deploy one per room for granular visibility, or one per zone for portfolio-scale coverage.

CO2 is the most valuable passive sensor signal. The rise rate indicates occupancy. The decay curve reveals ventilation rate in air changes per hour. One sensor gives you both without additional hardware.

Battery life optimised at one-minute sampling intervals. Leased in Monitor, Housing, and Complete packages.

Leased, never bought

Hardware stays on our books, not yours

Every piece of Algi hardware is leased as part of your subscription. There is no capital expenditure, no depreciation to manage, no end-of-life disposal. If a unit fails, we replace it. If you cancel, we collect it. The hardware is operational expenditure, treated the same way as your software subscription.

Zero capex
Operational expenditure only
Replaced if faulty
No maintenance contracts
Collected on exit
No disposal liability

Common questions about the hardware

Do I need hardware to use Algi?
No. Essentials and Comply are software-only packages that work from your energy bills and public data. Hardware is an add-on for Monitor, Housing, and Complete packages.
What does the Bio Wall actually do?
The Bio Wall is a living Spirulina panel that processes airborne particulates and CO2 as part of the building's air handling system. It complements HVAC rather than replacing it, and has shown load reductions of 25-30%* per room in controlled testing.
How is the hardware installed?
Algi Sense is wireless and battery powered. It installs in minutes with no wiring. The Algi Hub connects to your network via ethernet or WiFi. The Bio Wall requires connection to the building's fresh air supply, which is handled by our installation team.
What happens if hardware fails?
All hardware is leased. If a unit fails, we replace it at no additional cost. There are no maintenance contracts and no repair bills.
Is the Bio Wall patented?
Patent application GB2404515.5 is pending. The Bio Wall is an Enterprise-tier product available after the software platform has established the building's baseline performance.
Can I buy the hardware outright?
No. All Algi hardware is leased as part of the subscription. This keeps it as operational expenditure on your books and ensures we maintain responsibility for the equipment throughout its life.
