On Demand Energy Strategy · 500,000 sq ft
Technik connects day-to-day building operations into one intelligent system, delivering sustainable plant operation through BMS/IoT integration. Our ‘On Demand’ methodology runs equipment only when it is actually needed, here, across an entire commercial estate, without sacrificing comfort.
The landlord needed a wireless, adaptable way to bring their primary air-handling units onto an on-demand strategy, without disruptive cabling across an occupied 500,000 sq ft estate.
As with most offices, in-house demand-strategy engineering wasn’t on hand. Technik bridges that gap, linking remote sensor specialists to the right application of IoT in the building.
We deployed Pressac wireless air-quality sensors, integrated through the landlord’s BMS, so the AHUs run to meet real-time occupancy.
A wireless network places 70 IAQ sensors and gateways across the whole occupied space, and talks to the BMS live, leaving room for further demand-based initiatives down the line.
Sequence of operation
70 wireless IAQ sensors read conditions across each core and floor of the occupied space.
The building software gains live visibility of the actual HVAC requirement, floor by floor.
Where a space is unoccupied, dampers reduce the volume of supplied air to match.
The associated AHU ramps down in turn, cutting mechanical load and the heating or cooling of excess outside air.
What mattered
Trending the incoming data so the team can forecast future savings with confidence.
Clean integration with the landlord BMS, the single factor this project hinged on.
A transparent design, fully integrated with the Building Operations Platform.
Outcomes
Site metering indicates roughly 75,000 kWh/yr of AHU mechanical saving, with a similar amount again from no longer heating and cooling excess outside air, about 150,000 kWh/yr in total, driving a rapid ROI.
A clear, measurable contribution to the client’s carbon-intensity reduction targets.
~150,000 kWh/yr avoidedBuilt only from open-protocol products, so everything installed stays maintainable by the incumbent BMS company.
Now being shaped into a scalable retrofit package for existing offices looking to cut unnecessary consumption, run hours, and plant wear.
A proficient example of innovative demand-strategy implementation, collaboration across multiple parties resulting in best-practice energy management.Phil Draper, FCIBSE CEngChartered Building Services Engineer
