{{Main|Senedd building}}

The [[debating chamber]] in [[Cardiff Bay]], the ''[[Senedd building|Senedd]]'' (''Senate''), was designed by the [[Richard Rogers Partnership]], and built by [[Taylor Woodrow]], with environmental, mechanical, electrical and plumbing design by BDSP Partnership. It uses traditional Welsh materials, such as slate and [[Welsh oak (tree)|Welsh oak]], in its construction, and the design is based around the concepts of openness and transparency. The timber ceiling and centre funnel, manufactured and installed by BCL Timber Projects (sub-contracted by Taylor Woodrow) is made from Canadian sourced Western Red Cedar.

The Senedd is designed to be environmentally friendly: it uses an Earth Heat Exchange system for heating; rainwater is collected from the roof and used for flushing toilets and cleaning windows, and the roof features a wind cowl which funnels natural light and air into the debating chamber below.<ref>{{cite web|url=http://www.urban75.org/photos/wales/welsh-assembly-senedd.html |title=National Assembly for Wales – the Senedd, Cardiff Bay, docks and Tiger Bay, Cardiff, south Wales |publisher=Urban75.org |access-date=21 May 2011}}</ref>
