Lakhta Center is a multifunctional complex in St. Petersburg with the Gazprom headquarter and public spaces occupying a third of the area. Construction was completed in October 2018, now start work on the arrangement of business and public areas. The opening will take place in about a year, when the complex will be fully prepared to meet guests.
Cold accumulators make it possible to control peak loads in a climatic system. Energy is accumulated at low peak hours and used when cooling need is the highest.
This technology reduces an adverse environmental impact, reduces CO2 emissions.
Power consumption at peak hours is reduced, saving is up to 15%. Power bill amounts are reduced too especially accounting for a double-tariff system. At night when tariff is minimal when equipment operates not at full swing, excessive cooling power is used to accumulate cold in the form of ice. During the day when it is warm and there are a lot of people in offices when cooling equipment operates at full swing, accumulated cold is of help and reduces loads.
In the tallest skyscraper in the world, Burg Khalifa the centralized cooling supply system is enormous and very costly. A high capacity chiller is installed there. Without this electric unit, 13,000 tons of ice would be required to cool the building on a daily basis.
In Europe they save energy. After rehabilitation the twin towers of Deutsche Bank Headquarters in Frankfut-an-Main (Germany) have their own ice storage facility. These Green Towers are considered as one of the most ecologically friendly skyscrapers in the world.
Our skyscraper Lakhta Center is also in a row of green buildings. Cold accumulators are one of ecologically friendly green technologies which will be used here.
