Object: session hall of the Lviv City Council
Installed equipment:

• The EcoTouch Air Kaskade air/water cascade heat pump with a capacity of 27 kW (at A2/W35) of the company Waterkotte. Cascading and inverter technology allow the system to respond flexibly and with the highest efficiency to changes in the need for thermal energy.
• The project received a fairly simple configuration, apart from the internal unit of the heat pump, there was a storage tank, an Oventrop pump group with a highly efficient circulation pump of the new generation Wilo Stratos Maxo and an emergency electric heater with a capacity of 12 kW.
  The heating unit itself, located at the entrance to the session hall next to the wardrobe, has become an element of the interior and will serve as a clear example of the introduction of energy-efficient technologies.
• The low-temperature "underfloor heating" system is used for heating and cooling the premises. In order for the system to work as efficiently as possible, a special textile covering adapted for underfloor heating with low thermal resistance was selected.
  Automation system SmartComfort, Eurotherm company monitors temperature and humidity indicators in heating and cooling mode. Remote access allows you to control all elements of the system from anywhere in the world, via the Internet
• Ventilation installation of external weatherproof design LG 2500 of the company Pichler.
  The ventilation unit is equipped with a highly efficient cross-flow recuperator made of aluminum. Modern fans with EU technology provide the necessary performance and low noise level. Integrated silencers on all sides of the installation make the operation of the ventilator practically silent. The machine is equipped with filters that remove dust, pollen and other polluting particles.
• Climate panels Comfort Breeze Waterkotte are used for air distribution in the room. The multifunctional panel combines underfloor heating and ventilation, increasing energy efficiency. Ventilation air is supplied to the room through the floor panel, in which additional heating or cooling takes place, without additional energy consumption, and at the same time, air temperature differences are leveled. Climate system Comfort Breeze is made of polystyrene and meets the highest hygienic requirements. Also, such a solution improves indoor air quality, as polluted air is forced upwards thanks to the supply from the floor.
• Electric blinds integrated into the interframe space of the windows were used to provide external sun protection.Thanks to the installed weather station, the position of the slats changes depending on the position of the sun and the intensity of radiation. This will make it possible to significantly reduce energy consumption for cooling the premises.
• All supporting structures and fasteners are made on the basis of Walraven mounting elements.
