Eco tower: glass towers are not necessarily eco friendly. This one shows how new architecture can be evolved from ecological and humane principles.


Murphy/Jahn's Post Tower dominates Bonn's former government quarter which forms the city edge against the Rhineside Central Park. Formally, the tower complements Egon Eiermann's Langer Eugen tower, previously for the civil service and now to be occupied by the UN, and Gunter Behnisch's parliament building (AR March 1993), which will become a conference centre now that the Bundestag has moved to Berlin.

The new tower develops the best traditions of modern German office building. Most offices are for one to three people; all have windows and views over river and city. Energy efficiency and conservation are equally generative gen·er·a·tive

 in the parti. Basically, the building consists of the 162m office tower and a four-storey semi-detached podium podium

In architecture, a pedestal on a large scale. It may be any of various elements that form the base of a structure, such as the platform forming the floor and substructure of a Classical temple, a low wall supporting columns, or the structurally or decoratively
 block containing auditoria and the larger meeting rooms.

In plan, the tower is an oval, split down the middle, with the two halves slightly shifted against each other. Connecting the two arcs of accommodation is the 7.2m wide vertical circulation and services core. In this, every nine storeys, there is the glass floor of a skygarden which acts as a communications level and vertical circulation crossover Crossover

The point on a stock chart when a security and an indicator intersect. Crossovers are used by technical analysts to aid in forecasting the future movements in the price of a stock. In most technical analysis models, a crossover is a signal to either buy or sell.
. Banks of glass lifts are in the middle of the skygardens, providing views and orientation.

Tower walls have a double skin of glass. The outer layer is a rainscreen and there are automatically regulated blinds in the voids between inner and outer layers of glass which are over a metre wide. The thermal mass Thermal mass, in the most general sense, is any mass that absorbs and holds heat. In the architectural sense, it is any mass that absorbs and stores heat during sunny periods when the heat is not desirable in the living space of a building, and then releases the heat during  of the building's concrete structure is called into play as part of the interior climate control system, using a cast-in pipe system that circulates water heated and cooled as necessary, partly using waste heat. Automated glass flaps in the rainscreens admit fresh air to the cavity to balance room temperatures; and air flow in the cavity can be mechanically assisted when necessary. Exhaust air from the offices conditions the climate of the skygardens, which themselves can obtain natural cross-ventilation through the louvred glass walls at their outer (east and west) ends.

All these systems are integrated and controlled by a computerized building management system. The building cost, even with the computerized system and the double glass shell, is reckoned to be no greater than for a conventional sealed air-conditioned building, and operating costs operating costs nplgastos mpl operacionales  are expected to be 60 per cent less.

Spatially, the building has the drama of the central voids and skygardens: often rather giddy-making. In contrast, the curved office corridors avoid the institutional feeling of so many German office buildings, in which the ruthless dominion dominion, power to rule, or that which is subject to rule.
