The modernisation programme of the Diuna office complex in Warsaw is nearing completion. Thanks to the project, the 6,000 sqm concrete car park turns into a green park open to the city, covered with green hills. The project is changing its name from Marynarska Business Park to Diuna.
The Diuna project covers three areas: the outdoor space and surroundings of the buildings, the entrance lobbies of the four office buildings, and improvements to the ventilation, heat and air-conditioning systems, enabling a significant improvement in the energy efficiency of the project – Property Forum reports.
Setting a new direction that office buildings must follow
An energy audit carried out prior to the modernisation process resulted in the introduction of a number of solutions to improve the operation of building systems, e.g., CO2-dependent ventilation control, installation of VAV ventilation systems, airflow control, and replacement of cooling units to achieve up to 22% energy savings. In addition, a smart building control system based on artificial intelligence is implemented, which will bring 11.6% savings in energy used by HVAC systems.
Water consumption has been reduced by regulating flows in fittings in common areas, a leak detection and prevention system has been introduced, and a rainwater tank has been installed. The project has placed great emphasis on applying principles of circular economy. All the greenery from the original square has been distributed to the tenants, some of the materials have already been re-used in the project, and the remaining elements are waiting for a second life in storage.
“Diuna is changing the business image of Służewiec and setting a new direction that office buildings must follow to remain an attractive space for investors, tenants, and the local community. The new name of our project is the symbolic start of the next sustainable stage in its life. The most important work has been completed, including the creation of a new, open-access park, which is a showpiece of the complex.”- Witold Zatoński, founder of Syrena Real Estate
Covered in vegetation
Architecture studio MJZ has designed the project’s new look. The concrete patio has been transformed into a park, filled with trees and native vegetation. In order to create a coherent and friendly environment, the park sits on a rise-an-fall terrain covered with vegetation. The hills were constructed with lightweight materials so as not to disrupt the underground structure.
The foundation slab of the underground garage is supported by 50 columns, which serve as structures for 50 trees placed in special pots. The area now features green dunes, overgrown with 12 species of trees (50 trees) and 96 types of shrubs. This is native greenery that is important for sustainable projects.
“The Diuna patio has been designed according to the concept of biophilic design, which provides that humans have an innate tendency to seek a connection with nature and a sense of belonging to the natural world. The hills and the alleys between them create cosy spaces filled with vegetation, where you can calm down and get away from everyday life. You can stroll, relax and enjoy a cup of coffee between our green dunes. We believe that mental health is as important for tenants and their employees as physical health, which is why we have prioritised greenery and nature supporting human well-being.” – Maciej Jakub Zawadzki of MJZ Studio
The complex is screened from traffic by anti-smog screens totalling 416 sqm. The patio is pedestrian and biker friendly. Car traffic is banned across the area, and only short-term stops are possible. Diuna also offers a new infrastructure dedicated to cyclists, who can use 114 parking spaces on the underground level, a changing room with showers, four chargers for electric bicycles, self-repair stations, and ground-level racks. Car parking is located in the three-level underground garage which offers 1,300 spaces for tenants and guests of the complex.
Aiming for Breeam In-Use
Diuna (formerly Marynarska Business Park) comprises four office buildings with a total usable area of 46,000 sqm. Its corporate tenants include Accord, NewCold, Colgate, Daikin Europe, Eurocash, Ford, JDE, Oceanic, S.C Johnson, Sitel, Business Lease, Leasing Team, and WDX. The complex houses a Luxmed clinic and a Gorąco Polecam café. The complex has a WELL Health & Safety Rating and WIREDSCORE certification at the Silver level.
Following the refurbishment, Diuna will apply for Breeam In-Use certification under the new v6 system. The developer is also working with the Integration Foundation to make the investment as suitable as possible for people with disabilities.
