The building complex consists of two slim line multistory buildings with 28 and 33 floors respectively, a hotel and a five-story office building. The office and hotel complex is situated in a prime location and forms the "Northern Gateway" to Munich.

Energy Concept
The optimized facade concept for the "Hochhaus Ensemble am Münchner Tor", as developed by Transsolar Energietechnik GmbH, uses a high-insulating triple glazing with selective neutral sun protective coating on the exterior glazing plane. Good daylight transmission of 47% and minimum total solar heat gains of 24%, in addition to excellent thermal
protection (u-value: 0,7 W/qmK), are achieved by means of gas filling and an additional low-e coating on the inner pane. This optimized facade enables the use of a wind-independent, highly reflecting internal blind system as a sun protection combination with a displacement ventilation system, which is supplied with fresh air from decentral fan rooms on every floor. The combination of optimized building shell, displacement ventilation system and radiative cooling through an embedded piping system integrated into the non-suspended solid slabs, provides a comfortable enviroment temperature in accordance with DIN 1946. The slab cooling is driven at night by free cooling in evaporative cooling towers.
