Field reports, technical deep dives and good practice in MCR and BMS engineering, published by the Workswell engineering firm in Sion.
ProKilowatt covers up to 30 % of the investment in an electrical efficiency measure. But it only funds what would not happen without it: below a four-year payback, the answer is no. On ventilation, that is exactly where the best retrofits sit.
Strike every brand name out of a supervision tender and count how many suppliers can still answer it. If the answer is one, the competition is decorative.
It is not a question of competence, still less of honesty, but of position. For whoever programmed the installation, observed operation is the intent, and an audit is precisely the exercise of telling the two apart.
Placing one master on each floor instead of grouping all three in the panel takes the powerline out of the risers. Same hardware, same catalogue limit, a radically different installation.
Two devices that are both “BACnet compatible” can still work together very poorly. Two documents, requested before you place the order, save weeks of rework at the end of the site.
The University of Fribourg has entrusted Workswell with the retrofit of its SAIA-Burgess controllers: site supervision, uninterrupted operation and KBOB guidelines built in from the design stage.
On a variable-volume installation, a fixed-threshold pressure switch ends up either blind or hypersensitive. Continuous ΔP measurement changes that.
At handover, nobody asks for the source code of the automation systems. Yet that is where twenty years of operating independence are decided.
On the quote, controls is just one line. In operation, it is the line that decides whether the building consumes energy sensibly or wastes it quietly.
Daytime cold recovery, night-time free cooling and the right trade-off on temperature difference: three points that make the difference at 35 °C.
KBOB naming of building installations is powerful once you understand it and opaque on first contact. Our editable address generator makes it readable.
Missing measurement points, controls that do not talk to each other, surprises at commissioning: what it costs to handle controls last, and how to scope them upstream.
Around 4% of losses in the belt transmission and 10% in the asynchronous motor. EC-SWAP replaces the whole assembly without touching the controls or the wiring.
A 0-10 V setpoint and a 0-10 V feedback signal work, but that is all. A bus-connected VAV box gives you thresholds, actual damper position and remote adjustment.
Network segmentation, device authentication, access logging: IEC 62443 already covers most of the Cyber Resilience Act requirements, applicable from 11 December 2027.
Workswell extends its offering with BAMO, its owner's project assistance service: end-to-end project steering, coordination of all stakeholders and SIA and KBOB compliance.
The five mistakes Workswell still sees regularly on BMS projects, and what we wish we could have said beforehand: late integration, closed systems, neglected training, skipped audits, sensors without intelligence.
Workswell has been appointed MCR/BMS engineer for the future innovation park of the Energypolis campus in Sion: control system design, supervision architecture and commissioning.
MBE-CH and AS-CH profiles, UTF-8, alarm classification, trend logging and integration from the SIA phases onwards: what the KBOB BACnet recommendation really requires of your projects.
The whole Workswell team wishes you happy holidays and thanks its clients and partners for their trust throughout the year.
WS-SMART-HG controls the entire heating plant: up to 8 heating groups, 100% web-based supervision, BACnet and Modbus compatibility, built-in safety functions and implementation through configuration alone.
Workswell opens its new office at Rue de l’Industrie 10 in Sion, strengthening its presence in Valais, closer to its clients and partners.
A Workswell solution that reuses the existing wiring of SAIA-Burgess PCD1 and PCD2 controllers to fit modern controllers without touching the electrical cabinet wiring, and up to 30% cheaper.
Anticipating constraints, controlling costs, meeting deadlines: the Workswell method for structuring your HVAC (CVS) planning on the MCR side, built on the KBOB guide.
As a specialist in the BACnet protocol, Workswell guarantees the integration of multi-brand solutions for the supervision and automation of HVAC, lighting, energy and security installations.
A Workswell patent makes it possible to replace an asynchronous motor with an EC motor without modifying the existing wiring or the building’s control system, with energy savings of up to 70%.
Workswell announces the official filing of a European patent for a technology that cuts energy consumption without heavy investment.
Workswell announces a new patent, currently under validation, that drastically cuts energy consumption without heavy investment.
Workswell and JPS Performance are launching an on-site self-consumption grouping (RCP/ZEV) in Courtelary: central management, energy independence and real-time transparency on consumption.
How to raise your solar self-consumption rate: energy audit, battery storage, load scheduling and real-time monitoring with Workswell.
Site report on a condominium building: an air handling unit running non-stop with clogged filters was costing up to 25 kWh per day.
A first conversation is usually enough to define the potential and the scope of the mandate.
