Overnight ventilation of the atrium makes the building take longer to heat up during the day.

Mechanically supported night-time ventilation improves the controllability and heat dissipation in midsummer.

By bypassing the heat exchanger, ventilation systems or devices can also be used for night-time ventilation.

The passive cooling of the building using night-time ventilation in summer is showing some very good results.

Conventional night ventilation involves the replacement of warm air in the building with cold night-time air.

As with all other applications, however, heat removal by means of night ventilation is necessary.

Shading systems and night ventilation are sufficient in order to prevent overheating during the summer.

Cooling via night ventilation and borehole heat exchangers creates a pleasant indoor climate in summer.

The concept is supported with night-time ventilation via the ventilation systems.

The mountains behind them ensure a cool nighttime ventilation.

This caused the nighttime ventilation to be activated.

The building has passive cooling with night ventilation as well as a daylight-optimised façade design.

Since November 2014, the operator has dispensed with continuous night-time ventilation.

Natural night ventilation cools the building mass and the air in the room effectively in the summer.

Passive cooling of the building using night ventilation was one focus of this project.

Despite difficulties with night ventilation, the thermal insulation strategy that was implemented for summer periods proved to be effective.

The pressure difference between the office and exterior that is necessary during night ventilation has not yet been achieved.

A system for building cooling through active night-time ventilation existing at the laboratory stage was developed to series maturity.

The adiabatic cooling release, supply air temperatures, switching between summer and winter operation as well as the regulation of the night-time ventilation have now been adapted to improve this.

Cooling concepts with natural or mechanical overnight ventilation have been successfully implemented in office buildings and commercial buildings in recent years.

Heat management and the desired stabilisation of room temperatures operate in a largely passive manner if night ventilation removes heat during the night.

The detailed analysis of the building “Landhaus” in Bregenz and the “Oberlandesgericht“ in Linz have shown that optimal load reduction measures (shading, computer equipment, lighting, storage mass) in combination with an efficient night ventilation can be enough to reach a predominant comfortable indoor climate.

Further studies were carried out in an administrative building (22,610 m2 of heated net floor area) with regenerative passive cooling via a geothermal heat exchanger and natural night ventilation.

However, the potential offered by night ventilation could not be fully exploited as the planned volumetric flow rate of air of 160 m3/h through the outdoor air inlets was not being achieved.

The original specifications were full occupation of the building, no room temperatures over 26 °C and no night ventilation via windows and ventilation systems.

The printing house’s energy concept, based on underfloor heating, which uses waste heat, and cooling via borehole heat exchangers and night ventilation, relies on low exergy systems.

In northern Europe, internal and relatively high solar heat gains (long hours of sunshine when the sun is low) can be efficiently dissipated with cooler outdoor air by using natural ventilation during the day and night-time ventilation.

However, the potential offered by night ventilation could not be fully exploited as the planned volumetric flow rate of air of 160 m3/h through the outdoor air inlets was not being achieved.

Experience gained in low-energy office buildings cooled via overnight ventilation shows that pleasant room temperatures are achieved during summer even without air conditioning systems.
