The underside of the roof and cover shall be counterceiling in order to give room for concealed technical systems.
Electrical installations and central operational control system.
The Awarding Authority estimates a lighting system with focus on high-quality light technical solutions, energy saving and low operation and maintenance costs. It is estimated to use an after-glow emergency light system with signs at exits and fire technical equipment. A complete fire alarm system for the entire building shall be installed.
A necessary circuit system for lights, monitoring and HVAC technical systems shall be included. Connection and control locally and from a central operational control system. All alarm functions shall be integrated in the central operational control system, in addition to standard alarm functions. The central operational control system shall be WEB based in accordance with the municipality’s guidelines.

Ventilation in accordance with current regulations and the Norwegian Labour Inspection Authority’s regulations in relation to air volume and air replacements. Flue from common kitchen above ceiling.
The building shall have 1 balanced ventilation system for common areas/personnel areas with VAV control. Apartments shall be given separate ventilation generators.
Energy and environmental assessment.
In connection with planning and design of technical system for air conditioning, the principal objective has been to minimise the energy consumption and the climatic impact simultaneously as requirements in relation to indoor environment and cost effectiveness are safeguarded. The energy systems shall be simple, resilient and have longevity with emphasis on passive systems related to design and details of the building structure.
Existing district heating and gas network from Lyse shall be used. The project has used experience data from other projects in energy classification B. Use of 25 cm insulation in walls, 30 cm in roof and floors combined with a U-value of 1, 2 W/m2 for windows will give an annual energy consumption of approx. 100 kwh/m2. This is within the energy classification B’s requirements.
