Energy-optimising solutions in new buildings
Workplace Oo – A new construction project located in Oslo Municipality, Nydalen/Storo, with a strong focus on energy-optimising solutions
Project ID
The project focuses heavily on energy-optimising solutions, including heating and cooling from energy wells and recovery with battery exchangers.
"Workplace Oo is of a solid building quality and has energy class B, as low energy consumption is ensured through good solutions for energy supply, details and choice of materials. The building is divided into two bodies that are connected by a covered atrium made of glass, which provides daylight on all floors. The 24,000m2 building is spread over 8 floors and is the first thing you see when you get up from Storo’s metro station. (Quote: Workplace Oo)
EXHAUSTO AS was chosen AS the supplier of the ventilation solution, primarily because we at the factory in Flå are extremely flexible and can build the units according to the customer’s wishes. We also had production both in Flå and on the construction site.
Mounting the unit
The large CAHUs are produced in Flå, loaded on pallets and transported to the construction site for assembly “on site” in about three weeks.
The batteries (h=3 m, l=6 m) were hoisted into the basement of the building and then hoisted up into floor dividers before being lowered onto the base frame.
The sections were built around the batteries before the remaining sections were built up to the complete solution.
The large RVT400 CAHUs (65,000 m³/h) consist of 14 batteries in total and weigh approx. 2 tonnes per battery. Each of these consists of 6 fans – 3 for supply air and 3 for exhaust air. The fans are of type GMEB from FläktWoods. The air speed above the batteries is 1.1 m/s and up to 77% recovery is measured on these, recovered in the two large units.
All CAHUs are delivered without automation and connected to SD systems (CTS systems) from Sauter with the exception of SMART2, which is delivered with NA2 (CAV controlled).
