Example Use-Cases & Case Studies

These are concise summaries adapted from Adeunis case material; replicateable in the UK market with equivalent LoRaWAN/NB-IoT coverage.

1) Social Housing: Heating Optimisation at Scale

Problem: High gas bills and inconsistent temperatures across blocks with central plant.
Solution: ~3,000 sensors combining COMFORT (room T/H), external temperature, and DHW flow/return probes, all on LoRaWAN with KARE+ fleet management.
Outcome: Significant energy reduction, more stable comfort, fewer engineer call-outs.
Devices: COMFORT, TEMP/TEMP2S, PULSE on heat meters.

2) Schools & Public Buildings: Indoor Air Quality

Problem: Poor IAQ in classrooms and offices impacting health and learning.
Solution: COMFORT SERENITY and BREATH to track T/H/CO₂/VOC/PM; live LED feedback, threshold alerts to BMS/portal.
Outcome: Better ventilation control, compliance with IAQ directives, occupant confidence.
Devices: COMFORT SERENITY, BREATH. adeunis.com+1

3) Hospitality & Offices: Boiler Room & HVAC Oversight

Problem: Multiple sites with unknown plant performance; risk of Legionella due to DHW temperature drift.
Solution: Radio mapping with FTD, private LoRaWAN (Wattsense), deployment of PULSE on energy meters, TEMP2S on DHW loops, DELTA P on AHUs; data to an IoT platform for analytics.
Outcome: Verified coverage, reduced energy, proactive maintenance, DHW compliance.
Devices: FTD, PULSE, TEMP2S, DELTA P, plus platform connectivity. adeunis.com

4) Plant Rooms & Basements: Extending Reach
