The heat energy demand for heating is 46 % lower than required by the

Croatian building code.Energy savings

and basis of

calculation (eg. building

code, final energy consumption according to

bills, etc.)

Heat energy is produced by heat pumps integrated in air-condition system

using exhaust air and air from underground levels. Maximum heating and

ventilation capacity is 400 kW. Average COP level is 2.8. Heat energy for

cooling is supplied by adiabatic process, air-condition integrated mechanical

cooling and compact cooling device. Total cooling capacity is 1068 kW.

Average COP level is 4.1. Through integrated design concept high percentage

of energy recuperation is achieved – 80 to 92%.

The heat energy demand for heating is 71 % lower than required by national

code.Energy savings

and basis of



bills, etc.)

Large shopping, entertainment and communication areas are heated by

centralized air conditioning system consisting of ventilation chambers with heat

exchangers (summer - adiabatic cooling 60%, 1570 kW + external cooling

devices 40%, 1500 kW) and heat recovery (winter 75-85%, 4300 kW, COP 2,8

+ additional heating 1330 kW).

Heating system of retail area (60%) consists of heat pumps (air-water)

recovering waste heat of cooling system and additional heat (if needed) is

supplied by gas boiler (600 kW). Cooling energy is produced in external cooling

system. Fan coils are used for heat energy supply (heating and cooling).

All energy system are integrated with the digital regulation

which combines them into one energy efficient system. This is

achieved with free programmable control units, which allow

every function of the building being easily accommodated.

Digital regulation gets the final touch with the BMS, which

combines controlling, alarming, reporting and many other

complex components of the integrated system, with simple and

user friendly operating, from one or more places, also provides

excellent possibilities for data analyzing and optimizing and

rational use of enegy.

For heat energy production existing centralised system is used consisting of 2

boilers of 580 kW (existing) using natural gas. Heating and cooling distribution

system is reconstructed to 4 pipe fan coil system. Air conditioning system is

added using heat from centralised system. DHW is produced in centralised

system. Kitchen area is mechanically ventilated.

The main system uses condensing potential of the heat pump of 115 kW for

SHW preparation. Waste water from the sanitary block is used for the

evaporation. The waste sanitary water has sufficient thermal potential and in

energy balance gives about 80-90% of energy recovery.
