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. »

A suction and exhaust ventilation is designed in Lakhta Center. Air exchange-wise ventilation in Lakhta Center is general exchange, local, and anti-smoke. Air suction and exhaust is provided through louvres in the tower façade corners.

Ventilation is integrated in an integral system with central air conditioner.

A suction ventilation system is a system supplying a certain quantity of air inside which can be heated in winter and cooled in summer.
Exhaust ventilation serves for removing waste air from inside.

Air suction and exhaust is provided through louvres in façade corners. To reduce an impact of incoming air there is a protective curtain and air valves with electric heating.

Air is moistened to improve breathing, cell air washers are used.

Air washers are adiabatic moistening derived from external heating source, more cost effective than isothermal moistening.
Air washer is a thermal moisture exchange unit where air is treated with sprayed water. I the chamber there is a spraying system with rows of spray nozzles, an air outlet at air input, a droplet separator at air outlet, a tray with an automatic feeding valve, an overflow and filter for treatment of recirculating water. Water from the tray is supplied through pipelines with the help of a pump to nozzles and sprayed by them. Non-evaporated water flows into the tray.
The advantages of spraying chambers are simplicity of the structure and easy production, a capability to partially treat air from dust.

As zone terminal units fancoils are designed with an adjustable coolant flow.

A fancoil is a micro-climate system comprising a heat exchanger and a fan. A fancoil intakes air from inside with the help of a fan, supplies it to a heat exchanger where it is cooled or heated.

Five air conditioning units for office floors are designed by incorporating architectural features of the tower, the building has five facets (or beams).
Air conditioning units are located at plant floors with upper and lower location to the served floors. Horizontal interconnection layout of air ducts is avoided. It reduces the section of vertical shafts, makes it possible to place equipment compactly, simplifies the subsequent startup works, reduces an impact of arising variable gravitational natural pressure changing the internal aerodynamics of the building.

As zone terminal units in offices active cooling beams are designed.
Active cooling beams used in Europe since mid-90s of the last century, in North America, have come to be perceived recently as a serious alternative to air conditioning systems of non-residential buildings. Cooling beams not only condition the air but also provide incoming air. A cooling beam normally installed close to the ceiling or inside it is a kind of a radiator cooled by the use of an external source. The cooling beam cools space under it due to cooling of warm air naturally going up. Cooled air goes down back to the floor and the cycle repeats.

Cooling beams reduce a need in heavy air ducts and save energy because of the use of natural circulation.
