Test and Commissioning


1:1 Acoustic and indoor climate test

We invited1500 test-persons and askedfor their oppinionupon acoustic and indoor climate


Test in Rooms

Artificial heat gain during testingand adjustment of ventilation,cooling and BMS.

Documentation throughlogning and BMS


Energy effiency - Highlights


Energy effiency – General

Big roof gives shade for foyer

Bagside roof gives shade for canteen

Shaded glass

High insulation standard – Heat loss is 70% of public demands

LON controlled lightning by PIR sensors and daylight sensors


Energy effiency – ventilation

Very low velocity in ducts

VAV systems where possible

Frequency converters for all fans – even for CAV systems

Effective heat recovery in AHU’s

BMS controlled systems


Energy effiency - Mechanical

Freecooling

Very high cooling COP and high temperature cooling

District heating and low temperature heating

Frequency converters for all pumps

Low velocity in pipes

Dynamic balancing heating and cooling systems

High pressure mist systems
