Energy Aspects

What type of benefits can be obtained through ventilative cooling?

Benefits obtained through ventilative cooling include:

  • Reduction of the need of cooling capacity (kW)
  • Reduction of the cooling energy consumption (kWh)
  • Reduction of the CO2 emission
  • Comfortable or lower indoor air temperatures in case of a cooling demand
