Evaluation of the function and integration of glass-roofed air spaces (atriums) in non-residential buildings. Development of guidelines for energy- and comfort-optimized planning
ATRIEN - Evaluation of glazed air spaces in non-residential buildings
Development of a guideline for planning and operation
Does the integration of an atrium into a building contribute to increasing energy efficiency?
What strategies should be pursued when planning and operating atriums?
Cooling period
Integration of the maximum available opening areas into the ventilation of the green courtyards in summer
Implementation of consistent night-time ventilation that includes green courtyards and core buildings
Prevent window ventilation to the green courtyards during the day, instead use mechanical supply air to prevent overheated air from entering from the green courtyards
Heating period
Explicit consideration of the vegetation dormancy of the plants in the green courtyards through a temporally and locally limited temperature reduction, while maximizing the green courtyard temperature is aimed for outside the vegetation dormancy period
Use of solar pre-heated air from the green courtyards to ventilate the usage areas through free window ventilation instead of mechanical ventilation
Control of indoor air quality using CO2 sensors with free window ventilation
User instructions for the use of window ventilation when required
Finally, guidelines will be drawn up to enable specialist planners, architects and building managers to implement innovative designs for office buildings with large glass-roofed air spaces while complying with economic and ecological requirements in planning and operation.
