Tower of glass Rondo1, Warsaw, opened (PL)

The Rondo 1 office block has been officially opened by the developer of the project, Hochtief Project Development Polska.
Almost 200 meters high, walls of glass and steal, eighteen fast elevators this is Rondo1, the most modern high-rise building in Warsaw, which was built at the Rondo ONZ.

Rondo1 complex enchants with its modernity. It has very fast elevators, all lights oper-ated by computer, remote-controlled blinds, and 192 meters of hight. Its the first building in Europe, and second in the world, where a light control system based on the digital technology DALI, has been introduced on such a large scale. Each single light bulb in the building may be switched on, off, dimmed, or checked if it works or not. Without any additional cables, as all the above is done by an existing computer net-work. Thanks to this, Rondo1 is the most intelligent and brightest building of the capi-tal.

Warsaw joined an exlusive group of cities, which have a high-riser designed by a local Polish architecture company AZO in cooperation with the world-known architects from the American firm Skidmore, Owings & Merill, specialising in designing high-rise buildings. The firm designed, among others, the Sears Tower and the John Hancock Building in Chicago. When I was designing this building, I wanted it to become a showpiece of Warsaw. This is why we used some solutions which cannot be found anywhere else in the capital. said Larry Oltmans, American designer of the building. For the construction of Rondo1 we used high quality materials. Thanks to this, Rondo1 will be a modern building even after many years. adds the architect.

The complex seems to be very interesting to the tenants, and famous firms confirm the high quality offered by Rondo1. In the beginning of March this year, Hochtief De-velopment Polska Sp. z o.o., the developer of the complex of glass, has found a fur-ther big tennant, that is Volkswagen Bank Polska S.A.

Leased office space is about 3500 m2. Clerks of the bank will move in to Rondo1 in the second half of this year, and will occupy the 3rd and 4th floor of the glazed tower. Other reputable firms which rent office space are amongst others: an international audit and advisory firm Ernst&Young (floors from 14 to 21), Calyon Bank Polska, legal firm Baker&McKenzie, legal firm Domański, Zakrzewski, Palinka, Eurohypo Bank, Templeton, and Parkingi Polska. At the moment approximately 50% of the space is leased. We treat each tenant individually, fees are negotiated and they have a market value. Agreements signed to date, and big interest from potencial tenants prove this. - said Piotr Olbryś, President of Hochtief Project Development Polska Sp. z o.o.

Rondo1 is full of modern technology. It is the first entirely transparent building in War-saw. In order for the sunbeams not to disturb the persons working inside, remote-controlled blinds are installed. They will automatically adjust themselves to the sun-beams, depending on their angle. They will reflect the natural light onto the ceiling. In this way tenants will also save on electrical light. All the bulbs and halogens in the building are managed by a coputer programme. After dark, all blinds will be lifted, and lights all over the building will be switched on. This way, the situation when the build-ing is lit only in places where people work, can be avoided. Any light bulb in the building can be switched on or off, dimmed, or checked if it works or not. In Rondo1, the lighting system cooperates with the blinds system, in order to use the daylight more efficiently. After dark, all the blinds in the building will be lifted. The firm from Atlanta designed lighting of the building for the night-time, which will make the glazed skyscraper one of the characteristical points of Warsaw due to being very bright. says Piotr Stark of Hochtief Project Development Polska Sp. z o.o.

Efficiency of Rondo1 consists of many factors, such as: flexibility of office design, raised floors, full air conditioning with fan-coil system with a humidifying system. Raised
