Identifying excess consumption in shared building services
For a condominium building, Workswell analysed the electricity consumption of the shared services, focusing on excess consumption and energy inefficiencies.…
Self-consumption: understanding and optimising your energy
Why self-consumption matters today In the middle of an energy transition, self-consumption has become the obvious move: use the energy…
New self-consumption project in Courtelary with JPS Performance
Workswell, together with JPS Performance, is launching an on-site self-consumption grouping (RCP/ZEV) in Courtelary. Why a self-consumption grouping? Complete management:…
SAIA-Burgess retrofit at the University of Fribourg
The University of Fribourg has entrusted Workswell with the retrofit of its SAIA-Burgess controllers. A choice that says a lot…
Clogged filter: your pressure switch might be lying to you
A classic reflex in specifications for air handling units: fitting a differential pressure switch to detect clogged filters. On a…
Who really holds the keys to your building?
At handover, a building’s systems, certificates and warranties are carefully checked. But who thinks to ask for the source code…
A poorly scoped BMS costs almost nothing to install — you pay for it every month in operation
On the quote, controls is just one line among many. In operation, though, it’s the line that decides whether the…
Heatwave: now is when a double-flow AHU’s controls get put to the test
Three points make the difference when temperatures climb. Daytime cold recovery. When it’s 35 °C outside and the building is…
0026_MG10_H001_M100_S0: without the KBOB reading grid, this address means nothing to anyone
Naming and labeling of building installations (KBOB guideline “HVAC/Controls Technology”) follow a strict logic: a string of ASCII characters, structured…
On a building automation project, controls often arrive last in the chain
The result: missing measurement points, controls that don’t talk to each other, surprises at commissioning. Our role: coordinate upstream. Design…
Open a belt-driven AHU casing after ten years: the black dust on the floor is your belt
Elastomer particles in the airflow and throughout the casing. Tension needs retightening, pulleys go out of alignment, vibration, bearings need…
VAV controls: don’t fly blind
The classic setup: a 0-10 V setpoint signal to the damper, a 0-10 V flow feedback signal for control. It…
