UN City has been designed to limit the use of chemicals and pollutants during both its construction and its use. The air conditioning system uses seawater as a coolant, but if that cannot meet demand, back-up ‘chillers’ are used. The refrigerants selected are ozone friendly and have a lower effect on climate change than others. Environmentally-friendly, non-toxic materials were also used in the construction and furbishing of the building, to prevent long-term damage to health and the environment.
In compliance with Danish non-smoking laws, smoking is strictly prohibited in UN City. These rules guarantee a smoke-free environment to ensure that employees are not exposed to passive smoke at work. Banning cigarette smoke in the building also avoids the need for additional ventilation to maintain air quality, and so reduces energy consumption.
At UN City, a range of systems ensure the quality of indoor air to protect the health of staff members and visitors. The building complies with strict standards on chemicals and pollutants and is monitored by a number of CO2 sensors. Filters and mats have also been installed at all entry points to capture dirt and reduce the amount of particles of dust, pollen, smoke and other particles from entering the building.
Fresh air systems
UN City is entirely ventilated with filtered, outside air. This ensures that only clean, fresh air is present in the building and helps balance the interior humidity level. Outside air also helps to create a clean and pleasant indoor environment for the employees and guests of UN City. CO2 sensors have been placed throughout the facility to monitor the air quality and ensure an optimal airflow.
