Geothermal heating is recognized as the most environmentally-friendly way of heating. It has virtually no effect to the environment and minimizes the amount of CO2 gas emitted into the atmosphere. The heating quality coefficient of the next generation geothermal pumps used by Green Hall 2 reaches 98 percent. For comparison, the coefficient of the most efficient gas boilers is 97 percent.
But let's forget the numbers, as the most important thing is optimum operating temperature, which will always be 21 degrees, because the earth's energy is stable, unchanging and operating all year round. It ensures comfortable warmth in winter and refreshing coolness in summer. The operation of the system is ensured by 39 boreholes reaching 100 meters in depth, as well as 7 kilometres of pipelines.
The business centre has a modern microclimate control system which ensures that the indoor air is always fresh. The minimum amount of carbon dioxide improves the well-being and performance of employees. The system regulates moisture content and instantly removes unpleasant odours. During the warm season, an active chilled beam technology is used for ventilation, ensuring energy efficiency and the comfort of people working in the building. The ventilation system is decentralized and controlled separately on each floor. Therefore, tenants can control the microclimate of their own premises.
Green Hall 2 -open to nature and the sun. Because we can do more by working together with it. Green Hall 2 is designed so that each workplace is illuminated with high quality natural light. The facade of the building is comprised of 3800 square metres of particularly clear Guardian ExtraClear™ glass whose light transmission index is as high as 90 percent. The even distribution of light during the day is ensured by an automatic facade blind control system which moves together with the sun.
Creativity does not like consistency, therefore Green Hall 2 business centre has comfortable work zones enabling employees to work individually or with their colleagues. There are also cosy recreational islands for those who want to rest. During the warm season, those who want to change their office environment may do so in the green square installed near the business centre, as well as a special recreational space along Neris quay, where employees can work and enjoy the panorama of Neris river loop. Work productivity is ensured by high-speed wireless internet which covers the outdoor zones.
Green Hall 2 business centre achieves its efficiency by preserving nature and taking what is best from it. An architectural solution and particularly transparent glass ensure more natural light. The building uses geothermal heating that provides as much as 80 percent of energy necessary for heating and leaves minimal traces of CO2. The building's double-skin facade reduces the demand for thermal energy. Those who use electric cars will be able to rapidly charge them in the parking lots of the business centre, and those who travel to work on bicycles can use showers and changing rooms. Ecology lies even in the smallest details of the Green Hall 2 construction. When manufacturing window systems, environmentally-friendly castor oil-based insulators were used as an alternative for petroleum-based polymers.
