Project Outline – The Objective
Modeling, analysis and visualization of climatic concept is used to achieve information on heating and cooling demand and to answer following questions:
Where exactly is the heating and cooling capacity needed and in what amount?
Where are critical areas in terms of thermal comfort?
How is the performance of the intended climatic concept and how can it be improved?

Results Winter – Conclusions
Thermal comfort can be achieved by the proposed climatic concept with slight adjustments to improve local conditions.
The convectors along the perimeter and the balustrade are needed and have sufficient heating capacity to avoid downdraught from the façade and to ensure thermal comfort in all occupied zones.
The horizontal façade heating system in the vertical facades has not enough capacity to avoid condensate in all areas and can not guarantee sufficient thermal comfort close to the façade. Therefore, additional heating elements in the vertical frame structures were recommended.
The façade heating system of the roof (61 W/m² roof area) prevents condensate as well as discomfort due to cold surface temperatures.
Humidity control is recommended for all central AHU’s to maintain adequate supply air conditions for minimizing the risk of condensation.

Results Summer – Conclusions
Thermal comfort can be achieved in almost all areas by the proposed climatic concept. Modifications of the façade coverage as well as the climatic concept are required in order to reduce the room temperature on level 93 along terrace edge.
A closed restaurant area on level 92 along the terrace edge is necessary to reduce the significant influence on the comfort from the Bar on level 91.
Room temperatures can get higher than previously defined – but are still acceptable.
The balustrades need to be closed at the floor along the terrace edge to maintain appropriate comfort conditions on level 92 and 93.
It is recommended to provide additional cooling capacity by increasing the air flow rates temporarily.
