WELL(Building Standard) a LEED(Leadership in Energy and Environmental Design) are two of the most recognized certification systems for buildings that focus on sustainability, health and employee well-being. These certifications are designed to improve the quality of indoor and outdoor environments of buildings, with an emphasis on resource efficiency, reducing environmental impact and ensuring a healthy environment for employees.

WELL Certification
The WELL Building Standard is the first certification system focused exclusively on the health and well-being of people in buildings.
Modern office space should not only be functional, but also support health, well-being and performance of people.
Our vision was clear: to bring to Žilina offices that will not only be a place of performance, but a place where people feel good, motivated and healthy.
I start by analyzing every detail,that affects people's daily functioning — from air quality and light, through acoustics and design, to promote healthy habits. We have worked with experts in architecture, health and technology to create an environment that is not only aesthetically appealing, but also promotes physical and mental well-being.
Why it is important
- Healthier work environment:High indoor air quality, clean drinking water and low noise levels create ideal conditions for concentrated and comfortable work.
- Higher productivity: Natural light and biophilic design have been proven to increase employee performance and satisfaction.
- KCulture of well-being and balance: Within the building there are areas available for physical activity (fitness zones) and relaxation (green roof).

LEED Certificate
It is one of the most widely used building standards in the world. The collection of the criteria of this certification means optimizing every aspect of the building: from water consumption, energy efficiency, the value of materials to the quality of the internal environment.
NORDCITY Obchodná became the first building in Slovakia to receive the prestigious LEED Platinum v4 certification - the highest award for sustainability and energy efficiency of buildings.
Version v4 focuses on even greater efficiency and green solutions in areas such as:
- Energy efficiency: Reducing energy consumption and using renewable resources.
- Water savings: Modern technologies for efficient water management, including rainwater harvesting.
- Quality of the indoor environment:Strict monitoring of air quality and natural lighting.
- Sustainable building materials: Utilizing environmentally friendly materials with low environmental impact.

In the NORDCITY Obchodná 3D project, we regularly perform laboratory tests of water quality.
We monitor the content of dozens of substances to verify that tap water meets all applicable limits and is safe for direct consumption. This initiative promotes healthy hydration among building users while reducing the need for additional filtration or bottled water.
In the NORDCITY Obchodná 3D project, we regularly monitor air quality and test pollutant concentrations.
These measurements demonstrate that the indoor environment meets strict quality criteria, contributing to the health, comfort and focus of the building users.
