Some projects are covered by confidentiality agreements, so client names are omitted. Technical parameters and results are real.
A 1970s production building on a dependent connection scheme with an elevator unit. The task was to stop overheating in winter and underheating in shoulder seasons.
We designed an independent scheme with plate heat exchangers, variable-speed pump groups and weather-compensated control corrected by indoor air temperature.
Fourteen exhaust units, segregated air flows by room class, negative pressure maintained floor by floor.
The difficulty was simultaneous exhaust and supply operation with a variable number of fume hoods running. We implemented cascaded control with differential pressure priority.
A residential complex of twelve buildings with its own boiler house and four pump stations. Before the project: three daily rounds and parameters written by hand into a logbook.
We built a single control room: polling controllers over the existing network, mimic diagrams, trend logs, alarms to the duty engineer's phone.
The owner reported cold zones near the gates and ice on the roof. The cause had to be found before refurbishment started.
Thermal imaging, temperature and air flow measurements, air change checks. We found a break in the vapour barrier and incorrectly set air curtains.
A two-storey 1960s building, single-pipe system, cast iron radiators. The work ran during the school year, in stages, without stopping lessons.
We split the work into four phases by wing, kept the existing risers, replaced the radiators and balancing valves, added controls at the entry unit.
The full project list and client references are available on request. We can show sections and details from completed designs if you need to judge the quality of the documentation.
Tell us about the building and the task. We will say where to start: with a survey, a concept, or straight to detail design.
