Myntgata 2 is an historic area in Oslo consisting of five large buildings which surround a 5,500 m2 green courtyard. Four of the five buildings are from the end of the 19th century, and in 1950 they underwent a major renovation. The last building, called "German Brakka," is from 1949. The buildings were originally stabling and barracks for the military.
One of the buildings, at 3,000 m2, underwent a major renovation which will be completed in Spring 2019. The ventilation in the building was updated with automatically controlled natural ventilation. The architect on this project was oslo.works.
The facades windows are automated with intelligent window actuators that are controlled by WindowMaster’s indoor control solution, NV Embedded®. The system ensures appropriate and comfortable ventilation when controlling the windows by monitoring indoor temperature, indoor CO2 concentration, and outdoor conditions. The building has 28 ventilation zones which are individually controlled. The zones include office areas, common areas, meeting rooms, and hallways.
Most of the building is in two levels consisting of a ground floor and 1st floor. On the ground floor there are two areas which are double the height. This allows for buoyancy ventilation (stack ventilation). Other areas within the building are ventilated by cross ventilation or single-sided ventilation.
In addition to natural ventilation, four exhaust fans are located on the roof of the 1st floor in a hybrid ventilation strategy. This allows for increased buoyancy ventilation when needed.
WindowMaster BSI is responsible for regulating the natural and hybrid ventilation as well as the heating control. WindowMaster has also supplied smoke ventilation to the stair towers.
A special feature of NV Embedded® that building users can take advantage of is the ability to override the windows in their own zone via the NV Embedded® app.
