The competition to design the UN's first eco building has been won by a design team including multidisciplinary engineers King Shaw Associates and Austrian architects Daniel Fugenschuh with Kirstin Rogge. The facility, to be built in Podgorica, the capital city of Montenegro, will provide office space for six UN agencies.

The building is a low profile structure set into the landscape. A 1400 m2 screen of photovoltaic cells floats above the roof slab, providing a shading device as well as sufficient energy to meet the building's entire electrical demand.

It is designed to respond to the local sub-Mediterranean climate and incorporates heavy shading and a high degree of exposed thermal mass to regulate internal temperatures. Displacement ventilation will make use of heat generated in office spaces to drive air movement and allow natural ventilation to work effectively to cool the building for most of the year. River water will be used to provide additional cooling in the summer, and to heat the building using a heat pump in the winter run from the rooftop PVs.

It is hoped the building will be ready for completion by July 2007.
