Air-conditioning and controlling technics:
In 1978 Hans Huiberts got his master-degree of the Technical University of Delft at the department of Air-conditioning and Chilling Technics. At that time he was allready specialised in controlling technics. The last two years of his study he spent with the design and realisation of a control-strategy for an airhandling-unit at the lowest possible energy consumption, executed by a micro-processor. This was the first DDC-project (direct digital control) in the Netherlands!
In his work at the companies Fläkt and Burgplan he has put his knowledge into practice and constantly developped new strategies. Even "bad" installation-designs were made acceptable by means of software-cleverness.
His specialisms are of course not the standard radiatorgroups and dito AHU's, but the difficult or special projects, like the optimal integration of Total-Energy-installations and the reduction of its number of starts. Other examples are tapwater-temperature-boosting, storage of heat and/or cold in the soil or a buffertank, watertreatment, change-over-systems, dewpoint-control in public-baths, energy-saving measures, etc.

Building Management Systems:
Hans Huiberts has experience with several manufactures of BMS and has written free-programmable DDC-software for a.o. Tour & Andersson, Landis & Gyr, SAIA, Margaux, JELL and Andover Controls.

Communication-protocolls:
From 1991 lots of software-protocols have been realised in Andover Controls BMS to be able to communicate with other installations, like fire-detection-systems, security-systems, beeper-systems, chillers, power-aggregates, pump-controllers, energy-monitors, etc. Eather the protocols were standards, likes Modbus and J-bus, or were specialy developped in so-called Plain-English-programs.

Remote Control:
In 1980 Hans Huiberts introduced the "Remote Control"-system at Fläkt-Service, by which, for the first time in the Netherlands, remote installations were supervised through telephone-lines with a central mini-computer in the head-office in Amersfoort. The substations in the remote buildings were stand-alone DDC-controllers of well-known manufacturers (Tour & Andersson, Landis & Gyr, etc.). A coupling was made to the maintenance-systeem of Fläkt-Service. Alarms were automaticly distributed to service-people.
Some years later (1985) Huiberts became deputy-manager and head of the technical development at Burgplan b.v., where also remote control of installations was done, more with the aim of energy-savings. A lot of new routines he developped for several DDC-systems and the remote control was constantly improved.

When Burgplan was turned into EvoTech (on 1-1-1999), Huiberts started his own independant Consultancy and placed his knowledge at the disposal of several institutions and companies, among which EvoTech (later Cofely).
Also by Adviesbureau Huiberts a lot of work and inspection is done from the office in Castricum by telephone-lines and internet, so that customers are quickly served and there is no time-loss in traffic.

Energy-management:
Adviesbureau Huiberts can turn a BMS into a real management-system.
In all projects monitoring and saving of energy is a very important item. With the help of automatic reports of energy-usage, managers are able to see where the energy is going to and when. Automaticly produced degree-days- and running-hours-registrations are indispensable means of checking the usage.
Recently, smart routines are developped to not only diminish the usage, but also the costs. In the newest contracts of the energie-suppliers, demands are put to the minimum and maximum quantities of energy-usage, coupled with substantial fines. In some projects Adviesbureau Huiberts has recently acheived yearly savings of ten-thousands of Euro's, just by controlled usage!
