Have I mentioned that I love wood construction? That it sequesters carbon for the life of the building, is lightweight and gorgeous to look at? Now Various Architects (that's their name, not a group) are proposing the most sustainable office building in Norway. Among other attributes, it is built of and clad in wood. At Archdaily they write:
"A structural system of cross-laminated timber (CLT) panel walls and floors was chosen for being locally sourced with a high level of carbon sequestration. CLT represents a significant reduction in embodied CO2 compared to a traditional concrete or steel frame. The building exterior and insulated shutters are clad in Kebony, a norwegian wood product that is sustainable, low-maintenance, and suitable for the exposed seaside climate."

It has other neat features:
The building's wooden facade of individually operable insulated shutters is it's most visible and dynamic feature. Floor height shutters can be opened during the day to allow in daylight and passive solar heat, or closed after sunset on cold days for added insulation. The shutters can transform the facade from 60% to 20% window area. The inside surface of the shutters are tiled with LED lights to produce artificial daylight during the dark winter months to help provide a well-lit and healthy working environment year round. The insulated shutters are calculated to provide an additional 15% savings on heating yearly.
The architects conclude:
Various Architects and Ramboll believe that the ØKOntor project demonstrates that architects, engineers, and developers of new office buildings should push harder to develop highly energy efficient buildings with a zero net-carbon construction. We should not accept the minimum reductions required by law as standards, but should see them as a challenge to do better. Good luck to the COP15 representatives.
